Antigen presenting cell assay

Disclosed herein are methods for diagnosing or predicting acute cellular and / or humoral rejection in a subject. In one example, a method of assessing organ rejection includes contacting a first sample comprising antigen presenting cells (APCs) obtained from a subject in need of or having received an organ transplant with a donor antigen from a donor under conditions sufficient to induce uptake of the donor antigen; contacting a second sample comprising APCs obtained from the subject in need of or having received an organ transplant with a third-party antigen under conditions sufficient to induce uptake of the third-party antigen; and determining an antigen presenting index by determining a ratio of uptake of the donor antigen in the first sample to uptake of the third-party antigen in the second sample, wherein the ratio of greater than one indicates organ rejection and the APCs are monocytes or monocyte-derived cells.

Rapid one-step generation of antigen loaded dendritic cell vaccine from precursors

A one-step method for producing antigen loaded antigen-presenting cells from monocytes ex vivo has been found which comprises contacting the monocytes with a composition comprising an activator such as TNF alpha preferably in combination with at least one growth factor such as GM-CSF and at least one soluble or particulate antigen. According to the methods of the present invention, antigen-loaded dendritic cell vaccines can be generated within as little as three (3) days. In another method of the present invention, antigen loaded antigen-presenting cells are produced from monocytes ex vivo by contacting the monocytes with TNF alpha and granulocyte-macrophage colony stimulating factor at one time point to form antigen-presenting cells and then contacting antigen-presenting cells with soluble or particulate antigenic material antigen-presenting cells, wherein the antigen loaded antigen-presenting cells are produced in less than four days. The present invention also includes a vaccine which comprises monocyte-derived antigen loaded antigen-presenting cells, wherein the antigenpresenting cells are composed of two or more subsets selected from the group consisting of Langerhans cells with surface markers (CD 1 a+CD207+); interstitial dendritic cells with surface markers (CD 1a+CD207−); double negative dendritic cells with surface markers 20 (CD 1 a−CD 14−); and dendritic cells with surface markers (CD 14+CD 1 a−CD209+).

Method of using cd1d over-expression in human dendritic cells to enhance cd8+ t cell-based and invariant natural killer t cell-based antitumor immunity

The manipulation of human dendritic cells (DCs) to induce potent anti-tumor immunity remains an essential subject of study. Here we report that the overexpression of CD1d in human DCs can enhance the priming of naïve CD8+ T cells against tumor antigen. We showed that CD1d can be overexpressed in the human DCs using baculoviral vector carrying the CD1d gene. This CD1d-overexpression is functional as demonstrated by the increased expansion of invariant natural killer T (iNKT) cells while using these modified DCs to present α-galactosylceramide (α-GC). Pulsed with tumor antigenic peptide, these CD1d-overexpressing human DCs showed enhanced capability to prime naïve CD8+ T cells. CD1d-overexpressing human DCs also induced a pro-inflammatory cytokine profile that may favor the priming. Moreover, this CD1d-overexpression strategy can be extrapolated to monocyte-derived human DCs. Therefore, our study suggest that overexpression of CD1d in human DCs may provide a novel strategy to enhance DC immunogenicity and the possible translation into human cancer immunotherapy.

Compounds, kits and methods for conferring cytoprotection

hABCG2, a member of the ATP-Binding Cassette transporters has been identified as a protective pump against endogenous and exogenous toxic agents. ABCG2 was shown to be expressed at high levels in stem cells, and variably regulated during cell differentiation. It is demonstrated herein that functional ABCG2 is expressed in human monocyte-derived dendritic cells by the activation of a nuclear hormone receptor, PPARg. The present results uncovered a mechanism by which up-regulation of functional ABCG2 expression can be achieved via exogenous or endogenous activation of the lipid activated transcription factor, PPARg. Thus the invention relates to combined treatments by PPARg agonists and cytotoxic drugs transportable by ABCG2, various treatments in the field of neoplastic diseases as well as cell therapy, including autologous cell therapy, as well as kits and composition therefor. Method for protecting cells against cytotoxic drugs are also provided.

Methods and pharmaceutical compositions for modulating monocytopoiesis

Monocytopoiesis is a hematological process that supplies the periphery with monocytes and subsequently with macrophages and monocyte-derived dendritic cells. Typically, monocytes circulate in the bloodstream for a very short time before undergoing apoptosis, however, stimulatory signals can trigger monocyte survival by inhibiting the apoptotic pathway, and thus contribute to the maintenance of the inflammatory response. Accordingly, there is a need for methods and pharmaceutical compositions for modulating monocytopoiesis. Now, the inventors show that type I interferons signaling promote the differentiation of monocyte-derived phagocytes at the level of their progenitors. Importantly, IFN-alpha and -beta were found to efficiently generate the development of monocyte-derived antigen-presenting cells while having no impact on the precursor activity of conventional dendritic cells. Accordingly, modulators of type I interferon (e.g. neutralizing antibodies or type I IFN polypeptides) would be suitable for modulating monocytopoiesis in subjects in need thereof.
