AI Technical Summary
Tissue-resident memory cells (T RM ) are difficult to isolate and study due to their endogenous nature, hindering their application in basic research and adoptive cell therapy, and little is known about their differentiation.
An in vitro method involving hypoxic conditions and transforming growth factor β (TGF-β) is used to generate T RM -like T cells by culturing peripheral blood T cells, which includes activating them with anti-CD3 and anti-CD28 beads and further culturing in the presence of TGF-β to induce a T RM phenotype.
The method successfully generates T RM -like T cells expressing CD69 + CD103 + markers and having T RM -associated gene expression, mimicking endogenous T RM cells, facilitating their use in research and therapeutic applications.

DETAILED DESCRIPTION OF THE INVENTION
[0046] Tissue-resident memory cells (T RMare non-recirculating memory T cells present within tissues, lacking the molecules that enable their release from tissues and migration to lymph nodes, and act as frontline responders (Mami-Chouaib and Tartour, 2019). T RM Regarding differentiation, relatively little is known. Effector T cells that invade tissues can become T RM by upregulating or downregulating genes that enable tissue retention. In this study, it was found that hypoxia and TGF-β1 can induce a T + -like phenotype in human peripheral blood CD8 RM T cells. In this study, when human peripheral blood T cells, such as CD8 + T cells or CD4 + T cells, are differentiated in vitro under hypoxia and TGF-β1, they express a T RM phenotype and are shown to express protein markers and genes generally associated with tissue-resident memory cells (Table 1). These findings identify previously unreported factors regarding T RM differentiation and enable an easy means of generating T RM -phenotype cells for basic research and translational applications such as adoptive cell therapy.
[0047] Accordingly, certain embodiments of the present disclosure provide a method for generating T RM -phenotype cells. The terms "T RM -phenotype cells" and "T RMThe term "like cells" is used interchangeably herein to refer to the cells provided by the present method. The method can include culturing peripheral blood T cells under hypoxic conditions or in the presence of an agent that induces or mimics hypoxia. Exemplary hypoxia mimics include, but are not limited to, cobalt chloride (CoCl2), deferoxamine mesylate (DFOM), dimethyloxalylglycine (DMOG), or prolyl hydroxylase inhibitors such as roxadustat. During this period, the cells can be polyclonally activated, for example, by anti-CD3 and anti-CD28 beads, to generate early effector cells. The term "early effector cells" refers to cells within one week of activation from the naive state. Activation can include culturing in the presence of TCR stimulation and costimulation, including, but not limited to, anti-CD3 / anti-CD28 antibodies, anti-CD3 / anti-CD28 beads, feeder cells, antigen-presenting cells, artificial antigen-presenting cells, peptide and / or protein antigens, or combinations thereof. After activation to generate early effector cells, the cells are further cultured in the presence of TGF-β1 to generate T RM phenotype cells. Thus, hypoxia and TGF-β1 can be used to induce a CD8 RM cell population expressing human T + -associated markers CD69 + and CD103 + . Human CD8 T cells differentiated under hypoxia and TGF-β1 have T + -like transcriptional characteristics. RM
[0048] T RM -like cells can be antigen-specific. One method can include polyclonal activation of naive T cells under the conditions described herein for generating T RM -like cells, followed by transduction to express an antigen-specific TCR. In a modified version of the ETC stimulation method, naive T cells can be activated via peptide-pulsed antigen-presenting cells (or artificial antigen-presenting cells) under hypoxia and then further cultured in the presence of rh TGF-β1. This activation can be performed twice to generate antigen-specific cells. In another method, antigen-specific TRM Like cells may be generated by a combination of hypoxia and epigenetic modifiers such as TGF-β1 and HDAC inhibitors to differentiate the already expanded antigen-specific cells into a T RM phenotype.
[0049] The present T cells, for example, the starting population of T cells, may be modified T cells. In certain embodiments, the modified T cells include T cells expressing a chimeric antigen receptor (CAR T cells).

In certain embodiments, the modified cells are constructed using a gene transfer method based on a non-viral vector for introducing a nucleic acid encoding a chimeric antigen receptor specific for a desired target tumor antigen or a nucleic acid encoding a recombinant TCR specific for a desired tumor-specific epitope or neoepitope. In certain embodiments, the gene transfer method based on a viral vector includes a lentiviral vector. In certain embodiments, the gene transfer method based on a viral vector includes a retroviral vector. In certain embodiments, the gene transfer method based on a viral vector includes an adenovirus or an adeno-associated viral vector.

In certain embodiments, the subject has or is at risk of developing graft-versus-host disease. GVHD is a complication that can occur in any transplant that uses or contains stem cells from either a related or unrelated donor. There are two types of GVHD, acute and chronic. Acute GVHD appears within three months of transplantation. Symptoms of acute GVHD include a reddish rash on the hands and feet that may be accompanied by peeling or blistering skin, which spreads and can become more severe. Acute GVHD can also affect the gastrointestinal tract, in which case it presents with cramps, nausea, and diarrhea. Jaundice of the skin and eyes indicates that acute GVHD is affecting the liver. Chronic GVHD is ranked based on its severity: stage / grade 1 is mild; stage / grade 4 is severe. Chronic GVHD develops three months or more after transplantation. The symptoms of chronic GVHD are similar to those of acute GVHD, but chronic GVHD can also affect the mucous membranes of the eyes, the salivary glands of the mouth, and the glands that lubricate the stomach wall and intestines. Any of the populations of immune cells disclosed herein can be utilized. Examples of transplanted organs include solid organ grafts such as kidneys, livers, skin, pancreas, lungs, and / or hearts, or cell grafts such as islets, hepatocytes, myoblasts, bone marrow, or hematopoietic or other stem cells.

Examples
[0096] IV. Examples The following examples are included to demonstrate preferred embodiments of the invention. It should be understood by those skilled in the art that the techniques disclosed in the following examples represent techniques discovered by the inventors to function well in the practice of the invention and, thus, can be considered to constitute preferred modes for its practice. However, those skilled in the art will understand, in light of the present disclosure, that many changes can be made in the specific embodiments disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention.
[0097] Example 1 - Generation of Tissue Resident Memory T Cells Peripheral blood samples were obtained from healthy human subjects. Blood was sorted using FACS to naive (CD45RA + CCR7+ ) CD8 + T cells were isolated. Next, the T cells were activated polyclonally under atmospheric oxygen (about 20%) or hypoxia (2% O2) for 4 days to generate "naive effectors". Next, the naive effectors were cultured for an additional 2 days in the presence of 1.25 ng / mL of rhTGF-β1. Next, the cells were collected and analyzed for the expression of T RM -related genes and surface markers.
[0098] The combination of hypoxia and TGF-β1 induced a CD69 + CD103 + population, and it was found that human T-related markers including CD69 and CD103 were expressed (Figure 3). T RM -like T cells were further analyzed for changes in the expression of additional genes. It was found that cells cultured under hypoxic versus atmospheric oxygen conditions had changes in gene expression related to the T RM -like phenotype (Figure 2). RM
[0099] Naive CD8 + T cells were activated by hypoxia in the presence or absence of the addition of rhTGF-β1. The frequency of the CD69 + CD103 + population was evaluated by flow cytometry. It was found that hypoxia and TGF-β1 cooperate to induce CD69 + CD103 + cells (Figure 4).
[0100] Furthermore, it was found that the T RM -like phenotype cells induced by hypoxia and TGF-β1 showed transcriptional differences similar to those reported for endogenous T RM . It was found that CD69 - CD103 - , CD69 + CD103 - , and CD69 + CD103 +T cells were generated and selected, followed by RNA isolation and transcriptome analysis via RNA sequencing (n=3). RM Figure 9B shows a heat map depicting the expression of selected genes reported in the transcriptome analysis of CD8 from human lung. + CD69 + T cells vs. CD8 + CD69 - T cells and CD69 + CD103 + T induced in vitro with hypoxia and TGF-β1 RM (iT RM ) versus normal cell culture conditions (20% O2 without TGF-β1) - CD103 - Heatmaps comparing transcriptional differences (log2FC) in cells are shown. Differential expression was determined by |log2FC|≧1 and FDR<0.05.
[0101] This study demonstrated that hypoxia and TGF-β1 mediate the expression of CD8 + CD69 + CD103 + Induce cell populations and generate human T RM Expressing related markers and endogenous human T RM This study demonstrated that the in vivo T RM The antigen-specific T cells express another possible driver of differentiation and may allow for the development of adoptive cell therapy utilizing this unique cell type. RM This method provides the basis for an in vitro method for generating T-like cells. RM The phenotype can be used to generate cells having the phenotype.
[0102] Example 2 - Materials and Methods Cell Isolation and In Vitro Cell Culture: Peripheral blood mononuclear cells (PBMCs) from healthy donors were collected by leukapheresis and stored in liquid nitrogen until use. All human sample collections were performed with informed consent and approved by the Institutional Review Board (IRB) of UT MD Anderson Cancer Center. CD8 + T cells were enriched from healthy donor PBMCs using the StemCell EasySep™ kit. Next, cells were stained with fluorescent dye-conjugated antibodies against CD8, CD45RA, and CCR7. Naïve CD8 + CD45RA + CCR7 + cells were sorted using a FACSAria™ III or Fusion cell sorter (BD Biosciences). The sorted naïve cells were resuspended in cell culture medium (RPMI with 10% FBS, L-glutamine, and penicillin-streptomycin) containing 10 IU / ml of IL-2 (Prometheus) and equilibrated overnight in 2% oxygen in a hypoxic chamber (Coy Laboratory Products) or atmospheric oxygen (approximately 20%) in a standard cell culture incubator (Thermo Fisher). After equilibration, cells were activated with anti-CD3 / anti-CD28 beads (Dynabeads®, Gibco) for 4 days. On day 4, 1.25 ng / ml of recombinant human TGF-β1 (Biolegend) was added and cells were cultured for an additional 2 days. Antigen-specific CD8 + T cells generated via stimulation with autologous peptide-pulsed dendritic cells or TCR transduction followed by tetramer-based sorting were expanded using either a normal rapid expansion protocol (REP) or a TRM-modified REP. Anti-CD3 (OKT3) at 30 ng / mL was used to expand tetramer-positive cells for 10 - 14 days, either i) with the addition of IL-2 (50 IU / ml) in 20% oxygen and normal REP, or ii) with the addition of IL-15 (10 ng / ml) and rhTGF-β1 (1.25 ng / ml, starting on day 4) in 2% oxygen and modified REP, with 200 irradiated allogeneic PBMCs and LCLs as feeder cells to induce the T RM phenotype.
[0103] Flow cytometry: human T RM For the analysis of related markers, beads were removed from the cells, and the cells were washed once with staining buffer, and stained with Live / Dead Fixable Aqua (Life Technologies) and fluorescent dye-conjugated antibodies against CD8, CD69, CD103, PD-1, CD101, CXCR6, and CD49a (all from Biolegend). After staining, the cells were fixed with 4% paraformaldehyde fixation buffer (Biolegend), washed, and stored in staining buffer until analysis. The stained cells were analyzed using an ACEA Novocyte® 3000 flow cytometer. Compensation beads (UltraComp™, eBioscience) stained with a single fluorescent dye and fluorescence minus one (FMO) samples were used as controls. FlowJo software (BD Biosciences) was used to analyze the data.
[0104] Quantitative real-time PCR (qRT-PCR or qPCR): human T RM For the analysis of related gene expression, beads were removed from the cells, and the cells were washed once with PBS. The Qiagen RNeasy® Plus Mini Kit was used to isolate RNA according to the manufacturer's instructions. If necessary, the Qiagen RNeasy® MinElute Cleanup Kit was used to further purify and / or concentrate the RNA according to the manufacturer's instructions. First-strand cDNA was synthesized using M-MLV reverse transcriptase (Thermo Fisher). Quantitative real-time PCR was performed using a QuantStudio® 5 real-time PCR system and PowerUp™ SYBR® Green Master Mix (Applied Biosystems, ThermoFisher Scientific). Relative mRNA gene expression was normalized to the housekeeping gene RPL13A. The primers used are listed in the table below.

[0106] RNA-Sequence Determination Transcriptome Analysis: Cells were sorted using a FACSAria™ IIIu cell sorter (BD Biosciences), and then RNA was isolated using the Qiagen RNeasy® Plus Mini Kit, followed by the Qiagen RNeasy® MinElute Cleanup Kit. Libraries were constructed using the Illumina TruSeq Stranded mRNA Kit. RNA sequencing was performed using the Illumina NextSeq® 500 platform. Raw reads were mapped to the human (Homo sapiens) reference genome and transcriptome (GRCh38, GENCODE V23) using HISAT2 (version: 2.1.0). Counts for genes were obtained using Htseq-count (version: 2.1.0). Differentially expressed genes were identified using the R and Bioconductor package DESeq2 (version 1.14.1). Genes with FDR < 0.05 and |fold change| > 2 (mRNA only, obtaining protein-coding genes for P-value correction) were considered differentially expressed. The R and Bioconductor package fgsea (version 1.10.0) was used to determine whether a predefined gene set showed statistically significant concordant differences between two biological states (e.g., phenotypes). Gene sets were derived from several previously published T cell signatures. T RM Signatures were constructed from several experiments. Lung T RM and breast cancer TIL signatures were downloaded from the Gene Expression Omnibus (GEO), GSE61397 and GSE110938, respectively. False discovery rate (FDR) - corrected P-values less than 0.05 were considered significant or "true".
[0107] Functional analysis of genes differentially expressed (FDR < 0.05 and |fold change| > 2) was performed using Ingenuity® Pathway Analysis (IPA) software (version 48207413, Qiagen) with all genes in the Ingenuity Knowledge Base as a reference set, and by right-sided Fisher's exact test in a core analysis to determine whether a pathway was significantly altered between conditions (-log10[P-value] > 1.3).
[0108] Statistical analysis: GraphPad Prism (version 7, GraphPad software, San Diego, CA) was used to perform graphical representation and statistical analysis of the data.

[0109] Example 3 - Hypoxia acts as an environmental factor in the differentiation of human tissue-resident memory T cells Human CD8 + T cells differentiated under hypoxia and TGF-β1 acquire a T RM -like phenotype: Under conditions of relative hypoxia within inflamed tissues, it was hypothesized that hypoxia could provide an additional factor for T RM differentiation. To determine whether hypoxia could contribute to the induction of the T RM phenotype, naive (CD45RA + CCR7 + ) CD8 + T cells were isolated from human peripheral blood and activated for 4 days under hypoxia (2% O2) or normal cell culture conditions (atmospheric oxygen, ~20% O2) to generate "early effectors", and then cultured for an additional 2 days in the presence of rhTGF-β1.
[0110] Quantitative real-time PCR (qPCR) was used to evaluate a large panel of genes related to T RM transcriptional profiles. Cells differentiated under 2% O2 + TGF-β1 were human T RMshowed upregulation of most of the genes identified by Kumar et al. 2017 (incorporated herein by reference) as core transcriptional signatures (i.e., CD69, ITGAE (CD103), PDCD1 (PD-1), CD101, and CXCR6) (Figure 2A). In particular, no difference was observed in the transcript levels of ITGA1 (CD49a). Furthermore, transcripts of genes important in T cell recirculation (S1PR1, KLF2, SELL (CD62L)) were downregulated, further suggesting a resident memory phenotype. (Figure 2B). Previous reports in mouse models have shown that downregulation of S1PR1 and KLF2 is important for T RM differentiation, and reduced levels of these genes have been shown to be observed in endogenous human T RM as well. Transcripts in the transcription factor Eomes were dramatically reduced (Figure 2C). Tests in mice have shown that ablation of Eomes is required for TGF-β1 responsiveness and T RM establishment. IRF4 and RUNX3 were upregulated. The specific role of IRF4 in T RM is still unclear, but its upregulation has been reported in human T RM . The transcription factor RUNX3 has recently been identified as a major regulator of T RM differentiation. Finally, increased levels of transcripts encoding the effector molecules TNF-α and granzyme b were observed, similar to findings reported in human lung T RM (Figure 2D). Increased expression of the classical hypoxia-responsive genes SLC2A1 (Glut-1) and VEGF confirmed that the cells were responding to hypoxic conditions (Figure 1E). Overall, these results indicate that human CD8 + T cells acquire tissue-resident memory-like transcriptional characteristics when differentiated under hypoxia in combination with TGF-β1.
[0111] Human T RMFlow cytometry analysis to evaluate the protein-level expression of markers that are thought to be the core signature. In all healthy donors tested, under 2% O2 + TGF-β1 conditions, CD69 showed an increase in cells compared to 20% O2 + TGF-β1 conditions (Figure 2A). Cell viability was equivalent or superior in 2% O2 + TGF-β1 cells compared to 20% O2 + TGF-β1 cells (Figure 7B). These CD69 + CD103 + cells expressed PD-1, CD101, and CD49a (Figure 3B). In particular, CXCR6 surface protein expression was not observed despite transcriptional upregulation. The expression of both CD69 and CD103 is currently commonly used to clarify T + CD103 + but is partly due to the heterogeneous expression of CD69 and CD103 in endogenous resident memory cells, and there is still debate about which of these surface markers is most suitable for use in identifying T RM Therefore, from the 2% O2 + TGF-β1 condition, the expression levels of the related markers PD-1, CD101, and CD49a were compared among the CD69 RM CD103 - CD103 + CD69 + CD103 + CD69 + CD103 - populations. As expected, the CD69 RM CD103 + CD103 + population had the highest levels of PD-1 and CD101 surface expression (Figure 3C). CD49a expression was also high but equal to the expression levels observed in the CD69 + CD103 - population. In the comparison of different oxygen conditions, the most significant increase in the fold change of the population was found in the CD69 + CD103 + population (Figures 7C, 7D). Based on these results, CD69 as an in vitro-induced T RM cells + CD103 +It was chosen to focus on further analysis of the population.
[0112] Hypoxia and TGF-β1 exposure are T RM Synergistic factors for obtaining the phenotype: T cells are exposed to non-hypoxic oxygen levels in circulation because the atmospheric oxygen level under normal tissue culture conditions is higher than that experienced by T cells in vivo where the effect of 10% O2 (which is physiologically important) was evaluated. CD69 in 10% O2 + TGF-β1 + CD103 + There was a slight increase in T cells in 20% O2 + TGF-β1 compared to that in 20% O2 + TGF-β1, but after correction in multiple comparisons, it was revealed that there was no significant difference between the two conditions in the expression of signature genes (Figure 8A-E). Furthermore, CD69 RM CD103 + CD103 + The fold change of the population (O2 + TGF-β1 above 20%) was significantly greater in the 2% O2 + TGF-β1 condition versus the 10% O2 + TGF-β1 condition (Figure 8F).
[0113] Hypoxia and TGF-β1 of T RM To evaluate the respective contributions of hypoxia and TGF-β1 to the induction of phenotypic cells, in vitro differentiation experiments were performed under 2% O2 or 20% O2, in the presence or absence of the addition of rhTGF-β1. Consistent with published reports that hypoxia and TGF-β can each drive the expression of these markers, hypoxia mainly induced CD69 + cells while TGF-β1 induced CD103 + cells. Hypoxia or TGF-β1 alone did indeed induce a medium-sized population of CD69 + CD103 + cells, but the combination of hypoxia and TGF-β1 was seen to cooperate in the induction of the resident phenotype as the combined effect was significantly greater than the additive effect of either condition alone (Figure 4A). CD69 + CD103 + cells induced by hypoxia and TGF-β1 are T RMMarkers PD-1, CD101, and CD49a were expressed at high levels compared to the majority of the population under 20% O2 and 2% O2 conditions (each, CD69 - CD103 - and CD69 + CD103 - ) (Figure 4B).
[0114] In vitro-induced T RM showed enrichment in the endogenous human T RM gene signature: CD69 - CD103 - (20% O2) cells, CD69 + CD103 - (2% O2) cells, and CD69 + CD103 + (2% O2 + TGF-β1) cells, suggesting that differences in T RM marker expression represented distinct populations. Therefore, each phenotype was sorted and their transcriptional characteristics were analyzed by RNA sequencing. According to principal component analysis (PCA), these three populations were confirmed to be different from each other (Figure 5A). According to unsupervised hierarchical clustering, CD69 - CD103 - cells and CD69 + CD103 + cells had different gene signatures, while CD69 + CD103 - cells were shown to have somewhat intermediate transcriptional characteristics (Figures 5B, 5C). Comparison of the top differentially expressed genes between CD69 + CD103 + cells and CD69 - CD103 - cells showed gene expression patterns consistent with those reported for endogenous human T RM , such as increased expression of ITGAE, EGR2, GNLY, BMF, RASGEF1B, and NR4A1, and decreased expression of SELL, KLF2, and KLF3, indicating a non-recirculating transcriptional program (Figures 5B, 5C). The KLF2 target gene S1PR1 was also downregulated but did not meet the fold change threshold. CD69+ CD103 + The cells showed increased expression of ITGA1, PDCD1, CD101, and TNFRSF9, all of which are RM constantly reported to be upregulated in endogenous human T RM in vivo. An increase in the levels of the transcription factor NOTCH1, which is known to contribute to the
[0115] maintenance of endogenous T RM cells, and RBPJ, which plays a central role in Notch signaling, was observed (Figure 5C). RM Endogenous T + CD103 + cells often express various chemokines, presumably as part of their "alarm function" when mobilizing other immune cells to local tissues. Consistent with the chemokine properties of endogenous T RM cells, in vitro-induced CD69
[0116] CD103 - effector memory cells in the present study or CD103 - T cells within the same tissue site upregulated CXCL13 and CCL20, as well as CCL4, CCL5, and CCL22 (Figure 5C). Changes in the expression of genes that have often been reported in endogenous human T + T RM cells, such as upregulation of MYO7A and RGS1 and downregulation of SERPINE2, RAP1GAP2, RASGRP2, and FAM65B, were also observed, although their roles are unclear. - CD103 - To gain insights into the physiological relevance of these findings, gene set enrichment analysis (GSEA) was performed using gene signatures from published analyses of endogenous human CD103 + CD103 + compared to effector memory cells from peripheral blood or CD103 EM T cells within the same tissue site. According to the results, the transcriptional profiles of CD69 - CD103 RM cells were similar to the signatures of T+ CD103 - CD69 Compared to Cells + CD103 + Cells are exclusively T within the same tissue RM vs CD103 - was shown to be similar to the signature of T cells (Figure 5D). These results reflect the degree of difference in oxygen pressure during circulation relative to local tissues. Even among TILs within the same tumor, T cells within the tissue will be exposed to more similar oxygen levels compared to T cells in circulation, and multiple recent characteristics of TILs in various solid tumor types are related to CD103 + Resident memory-like TIL (TIL RM ) have been reported. Therefore, CD69 induced under hypoxia + TGF-β1 + CD103 + cells compared to CD69 + CD103 - cells induced under hypoxia alone, CD8 + CD69 + CD103 + vs CD8 + CD69 + CD103 - enrichment of the gene signature reported for breast cancer TIL was observed (Figure 5E, 5F). Since hypoxia and TGF-β are common features of the tumor microenvironment, as a result, these conditions may contribute to the generation of CD103 + TIL in vivo.
[0117] CD69 + CD103 + cells compared to CD69 - CD103 - cells according to Ingenuity Pathway Analysis (IPA), many of the differentially expressed genes were shown to be components of the glycolysis, gluconeogenesis, and TGF-β signaling pathways (Figure 6A). Given that the cells were exposed to hypoxia and TGF-β and assuming that hypoxia is a major regulator of cell metabolism, these results were expected. Enrichment of genes in the Notch signaling pathway was also observed, which is in endogenous human lung T RMreported within (Figure 6A). These findings raise questions about the role of metabolism in T RM differentiation. Hombrink et al. suggested that the major role of Notch signaling in lung T RM is the regulation of metabolic programs, as chemical inhibition of Notch signaling affected genes involved in glycolysis, oxidative phosphorylation, and fatty acid metabolic pathways. Similar to hypoxia, deletion of the purinergic receptor P2RX7, a known modifier of aerobic glycolysis, suggested that impaired metabolism via dysregulation of T RM formation, as P2RX7-deficient cells exhibited reduced mitochondrial mass and function, defects in aerobic glycolysis, and impaired glucose uptake.
[0118] Enrichment of differentially expressed genes involved in leukocyte extravasation signaling. Epithelial adhesion junction signaling, integrin signaling, and paxillin signaling were observed, all of which were involved in focal adhesion signaling and suggested changes in the programming of migration (Figure 6B). Consistent with previous reports that PI(3)K (phosphatidylinositol-3-OH kinase) signaling is involved in cytokine-induced downregulation of KLF2 and may play a role in the generation of T RM in vivo, multiple pathways involved in inositol phosphate signaling, namely, 3-phosphoinositide biosynthesis, the superpathway of inositol phosphate compounds, D-myo-inositol (1,4,5,6)-tetraphosphate biosynthesis, and D-myo-inositol (3,4,5,6)-tetraphosphate biosynthesis, were also enriched.
[0119] To more fully understand the functional relevance of the transcriptional characteristics induced by hypoxia + TGF-β, pathway analysis was also performed on the transcriptional data published by Kumar et al., and changes in Th1 and Th2 activation and granulocyte adhesion and extravasation pathways were observed in their endogenous lung T RM and in vitro-induced T RM and in vitro-induced T RMwere found to be common. In particular, across all datasets, axon guidance pathways were also highly significantly differentially regulated. Axon guidance was initially seemingly unrelated to resident memory T cells on the surface and current T RM has not been reported in the literature, but it is a process when environmental factors affect the migration pattern of cells. Many of the same elements that govern axon guidance are also known to regulate immune cell trafficking and can be regulated by hypoxia and / or TGF-β.
[0120] To evaluate the effect of the HIF prolyl hydroxylase inhibitor FG-4592 (roxadustat) in combination with TGFB1, further tests were conducted. Naïve CD8 + T cells isolated from peripheral blood were activated for 4 days under 20% O2 (AtmosO2) in the presence of the HIF prolyl hydroxylase inhibitor FG-4592 (roxadustat), and then further activated for 2 days with rhTGF-β1. On day 4, cells activated under 2% O2 (hypoxia) with the addition of rhTGF-β1 are shown in Figure 10A for comparison. The combination was found to induce + CD103 + CD69 cells (Figure 10A).
[0121] Next, naïve CD8 + T cells were stimulated with autologous monocyte-derived dendritic cells pulsed with the MART-1 (M27) peptide for 7 days under 20% O2 (AtmosO2) or 2% O2 on day 4 with the addition of rhTGF-β1, and + CD103 + antigen-specific (tetramer + ) T cells were generated (detected by flow cytometry) (Figure 10B). Used in an improved rapid expansion protocol with hypoxia and rhTGF-β1, within antigen-specific T cells RMThe phenotype was induced. Antigen-specific T cells were generated via stimulation with autologous MART-1 peptide-pulsed dendritic cells (ETC) or transduction of the TCR specific for gp100 (TCRT), labeled with a fluorescent dye-conjugated tetramer, and sorted. Next, the sorted antigen-specific T cells were stimulated with anti-CD3 (OKT3) and irradiated feeder cells under 20% O2, and IL-2 was added (normal REP) or IL-15 was added under 2% O2, and rhTGF-β1 was added after day 4. Thus, with the improved rapid expansion protocol, T RM phenotype was also shown to be induced (Figure 10C).
[0122] Therefore, in this study, in vitro T RM phenotype was reproduced from human peripheral blood-derived T cells, and hypoxia was identified as a potential factor in T RM differentiation. While there are obvious limitations to experiments feasible in humans, the described studies, supported by the observation that hypoxia + TGF-β-induced T RM mimics the transcriptional and proteomic landscapes of endogenous T RM as well as the pathways related to migration and metabolism, provide compelling evidence that hypoxia is an environmental factor that can contribute to the acquisition of the T RM phenotype.
