[0123] Detailed description of the invention 1.Summary The proteins described herein are in human form unless otherwise specified. The NCBI reference for the substance is as follows: human TβRII isoform A(h TβRII ロング ), NP_001020018.1, and human TβRII isopho 'B(hTβRII ショート ), (NP_003233.4). Native from humans The sequences of the TβRII protein are shown in Figures 1 and 2. In some embodiments, T βRII proteins are derived from non-human animals such as mice, rats, dairy cows, or monkeys. That is the case.

[0124] The TGFβ superfamily shares common sequence elements and structural motifs, and is diverse in its composition. It contains growth factors. These proteins are highly effective in both vertebrates and invertebrates. It is well known that it exerts biological effects on a wide variety of cell types. Superfamily The members play important roles in pattern formation and tissue specificity during embryonic development. Various processes including adipogenesis, myogenesis, chondrogenesis, cardiogenesis, hematopoiesis, neurogenesis, and epithelial cell differentiation. It can influence the differentiation process. It can manipulate the activity of members of the TGFβ family. By doing so, it is often possible to cause significant physiological changes in living organisms. For example Piedmontese and Belgian Blue cattle breeds exhibit a significant increase in muscle mass due to GD. It carries a loss-of-function mutation in the F8 gene (also known as myostatin). Grobet et al. Nat Genet. 1997, Vol. 17 (No. 1): pp. 71-74. Similarly, in humans, GDF8 The inactive allele is thought to be involved in muscle mass increase and, where it is believed, in exceptional strength. Related. Schuelke et al., N Engl J Med 2004, Vol. 350: pp. 2682-2688.

[0125] TGFβ signaling is classified into type I (e.g., TβRI) and type II (e.g., TβRII). The serine / threonine kinase receptor heteromer complex mediated ligand stimulation It then phosphorylates and activates downstream SMAD proteins (Massague, 2000, Na (t. Rev. Mol. Cell Biol. Vol. 1: pp. 169-178). These type I and type II receptors The substance consists of a ligand-binding extracellular domain with a cysteine-rich region and a transmembrane domain. It consists of a transmembrane and a cytoplasmic domain having predictive serine / threonine specificity. It is a protein. Type I receptors are essential for signal transduction, and type II receptors are rigorous. It is required for ligament binding and for the expression of type I receptors. Type I and type II receptors are ligament binding. After binding, a stable complex is formed, and as a result, the type I receptor is phosphorylated by the type II receptor. It will be oxidized. TGFβ is divided into three types: TGFβ1, TGFβ2, and TGFβ3. It has three mammalian isoforms, each of which has distinctly different mechanisms in vivo. It has the ability. The binding of TGFβ to TβRII opens the TGFβ signaling pathway. This is an extremely important step in getting things started, and this activation causes SMAD2 to be phosphorylated. As a result, the activated SMAD2 / SMAD4 complex is translocated to the nucleus and gene generation occurs. This will modulate the current state.

[0126] Therefore, in certain embodiments, this disclosure relates to various TGFβ1 or TGFβ3-related As an antagonist of TGFβ1 or TGFβ3 for use in treating disorders, Tβ We provide RII polypeptides that are not constrained by any particular mechanism of action. However, such polypeptides bind to TGFβ1 or TGFβ3 and these ligands It is expected to act by inhibiting the ability of the ternary signaling complex to form. .

[0127] This disclosure relates to a fusion tan comprising a TβRII polypeptide and a heterogeneous portion (e.g., an Fc portion). Provides protein. In certain embodiments, the TβRII portion and the heterogeneous portion are linked to the linker. Therefore, they are fused. As will be explained in more detail below, this disclosure is a linker of a certain length. TβRII-Fc fusion protein containing (for example, a linker with 21 amino acids) However, surprisingly, the TβRII-Fc fusion protein has a linker consisting of only four amino acids. We demonstrated that it was possible to bind to TGFβ-1 and TGFβ-3 with stronger affinity than the original substance. To testify.

[0159] In certain embodiments, the disclosure provides a method for altering the glycosylation of polypeptides. The aim is to induce specific mutations in the TβRII polypeptide. Such mutations are O Introducing one or more glycosylated sites, such as linked or N-linked glycosylated sites. It may be selected for the purpose of, or to eliminate. Asparagine linkage glycosylation recognition The site is a tripeptide sequence that is specifically recognized by the appropriate cellular glycosylation enzyme. , asparagine-X-threonine (or asparagine-X-serine) (where "X" is) It generally contains one or more serine or treonine amino acids. By the addition of a transcript residue, or by the addition of one or more serine or threonine residues Through this exchange, the sequence of the wild-type TβRII polypeptide (relative to the O-linked glycosylation site) You can also make changes.

Biochem., pp. 259-306, and are provided by: Incorporated herein by reference: one or The removal of multiple sugar chain substructures can be carried out chemically and / or enzymatically. Chemical deglycosylation is a process that involves, for example, the chemical deglycosylation of a compound such as trifluoromethanesulfonic acid or an equivalent compound. This may involve exposure of the compound to TβRII polypeptide. This procedure preserves the amino acid sequence. While retaining the linked sugars (N-acetylglucosamine or N-acetylgalactosamine) This results in the cleavage of most or all sugars except for (n). Chemical deglycosylation This is according to Hakimuddin et al. (1987) Arch. Biochem. Biophys. 259: 52. Furthermore, according to Edge et al. (1981) Anal. Biochem. Vol. 118: p. 131, It is listed that the enzymatic cleavage of the glycosylated substructure on TβRII polypeptide was performed by Thotakura et al. As described in (1987) Meth. Enzymol. Vol. 138: p. 350, various This can be accomplished by the use of endoglycosidases. Mammals, yeast, Insect and plant cells are all different types that can be influenced by the amino acid sequence of peptides. Since a lycosylation pattern can be introduced, it depends on the type of expression system used. The sequence of the TβRII polypeptide can be adjusted as appropriate. Generally, in humans TβRII polypeptides for use in mammalian cell lines that provide appropriate glycosylation For example, it will be expressed in HEK293 or CHO cell lines, but in other mammals. Animal-expressing cell lines, yeast cell lines with modified glycosylation enzymes, and insect cells are also available. It is expected to be useful.

[0160] This disclosure relates to mutants, particularly combinatorial mutants of TβRII polypeptides. We are further planning to develop a set of and methods for generating shortened mutants, combinatorial A pool of al-mutants is particularly useful for identifying functional mutant sequences. The purpose of screening a national library is, for example, to identify agonists or an TβRII polypeptide variants that can be used as either tagagonists, Alternatively, a TβRII polypeptide variant possessing all the novel activities together is generated. This is possible. Various screening assays are provided below, and such assays Mutants can be evaluated using this method. For example, the TβRII polypeptide mutant can be evaluated using Ability to bind to TβRII ligand, and the relationship between TβRII ligand and TβRII polypeptide. The ability to prevent binding, or to interfere with signaling induced by TβRII ligands. The ability to cross can be screened. TβRII polypeptide or The activity of the mutants can be evaluated using cell-based assays or in vivo assays, particularly in the examples. The test can also be performed using any of the assays disclosed herein.

[0161] A mutant induced by combinatorial chemistry, and naturally occurring TβRI A selective or Generally, mutants with increased efficacy can be generated. Similarly, mutations The induction has a variant with a dramatically different serum half-life compared to the corresponding wild-type TβRII polypeptide. It is possible to create different forms. For example, denatured proteins can be subjected to proteolytic degradation. Alternatively, it may cause the breakdown, removal, or inactivation of the native TβRII polypeptide. This makes it more stable for other processes that would otherwise cause problems, or it can be made less stable. Such mutants, and they By using a gene that modulates the half-life of the TβRII polypeptide, This can alter TβRII polypeptide levels. For example, a short half-life can be used to change the TβRII polypeptide level. It can produce short-term biological effects, and recombinant TβRII polypeptide in the patient's body This allows for more precise control at the cytoplasm level. In Fc fusion proteins, Mutations that alter the half-life of the protein are linked to the linker (if any) and / or F It can be added to part c.

[0162] The combinatorial library contains fewer possible TβRII polypeptide sequences. A degenerate library of genes encoding polypeptide libraries, each containing a portion of the same molecule. It can be created by Lee. For example, a mixture of synthetic oligonucleotides enzymatically It can ligate to the gene sequence, and as a result, the potential TβRII polypeptide A degenerate set of nucleotide sequences can be expressed as individual polypeptides, and Alternatively, as a larger set of fusion proteins (e.g., phage display), It can be expressed for the purpose of [reason].

[0163] From degenerate oligonucleotide sequences, the potential TβRII polypeptide variants There are many ways to generate ibraries. This involves the chemical synthesis of degenerate gene sequences. This is done using an automated DNA synthesis machine, and then the synthesized gene is transferred to a suitable vector for expression. It can be gated. The synthesis of degenerate oligonucleotides is a circumstance in the art. This is knowledge (for example, Narang, SA (1983) Tetrahedron Vol. 39: p. 3; Itakura et al.

Such methods have been used for the directional evolution of other proteins (for example, Scott et al., (1990) Science Vol. 249: pp. 386-390; Roberts et al., (199 (2nd year) PNAS USA Vol. 89: pp. 2429-2433; Devlin et al., (1990) Science Volume 249: pp. 404-406; Cwirla et al., (1990) PNAS USA Volume 87: 6378 ~Page 6382; and U.S. Patent Nos. 5,223,409 and 5,198,346 See also Nos. 5,096,815.

[0164] Alternatively, combinatorial libraries can be generated using other forms of mutagenesis. This can be done. For example, by generating a TβRII polypeptide variant and extracting it from a library. For example, a script that uses alanine scanning mutagenesis and similar methods.

In particular, combina In a trial setting, linker scanning mutagenesis is performed on the shortened (bioactive) form of Tβ. This is an attractive method for identifying RII polypeptides.

[0165] Gene products of combinatorial libraries created by point mutation and shortening To screen for, incidentally, gene products that possess certain characteristics A wide range of methods for screening cDNA libraries are available in this technology field. This is publicly known. Such methods involve combinatorial mutations of TβRII polypeptides. Generally applicable to rapid screening of gene libraries generated by gene induction. It is expected to be effective. It is most widely used for screening large gene libraries. The method involves cloning a gene library into a replicable expression vector. The resulting vector library is used to transform appropriate cells. The relatively easy isolation of the vector encoding the detected gene is a desirable activity. Under conditions facilitated by the detection of [specific element], combinatorial gene expression is usually performed. Includes. Preferred assays include the TβRII ligand binding assay and the ligand-mediated cell assay. Includes a Gunnar signaling assay.

[0169] 4. Different parts In certain embodiments, functional variants or modified forms of the TβRII polypeptide are Tβ A fusion tan having at least a portion of an RII polypeptide and one or more heterogeneous portions. It contains protein. Well-known examples of such heterogeneous parts include polyhistidine and Glu-Gl u, glutathione S transferase (GST), thioredoxin, protein A, p Rothein G, immunoglobulin heavy chain constant region (Fc), maltose-binding protein (MBP) Examples include, but are not limited to, human serum albumin, or the heterogeneous portion. You can select to assign the desired characteristics. For example, some heterogeneous parts are affiliate It is particularly useful for isolating fusion proteins by tide chromatography. For purification, glutathione conjugate resin, amylase conjugate resin, and affinity chromatography such as nickel or cobalt conjugate resins. A suitable matrix for the fee is used. Many such matrices are (H IS6) Useful Pharmacia GST purification system and fusion partner Available in kit form, such as the QIAexpress (trademark) system (Qiagen). It is possible. As another example, to facilitate the detection of heterologous parts of the TβRII polypeptide. , can be selected. Examples of such detection domains include various fluorescent proteins. Examples include (GFP, for example) and "epitope tags," where epitope tags are typically, It is a short peptide sequence for which a specific antibody can be used. A specific monoclonal antibody is readily available. Well-known epitope tags available for use include FLAG and influenza virus red. Examples include hemagglutination (HA) and c-myc tags. In some cases, heterogeneous parts are Protease cleavage region enables partial digestion of the fusion protein by the appropriate protease. It has a position, for example, a protease cleavage site of factor Xa or thrombin, thereby The recombinant protein is released from the fusion protein. Then, the released protein is... Subsequent chromatographic separation allows for isolation from heterogeneous regions. In one embodiment, the TβRII polypeptide is used in vivo. It is fused with a domain that stabilizes it ("stabilizer" domain). "and" refers to something that prolongs the serum half-life, and whether this prolongation is due to a decrease in disintegration, or kidney The question is whether this is due to decreased clearance by organs or to other pharmacokinetic effects. It means that fusion with the Fc portion of immunoglobulins is desired for a wide range of proteins. It is well known that this imparts specific pharmacokinetic properties. Similarly, fusion with human serum albumin is also possible. This can impart desirable characteristics. Other types of heterogeneous parts that can be selected include: Examples include polymerization domains (e.g., dimerization, tetramerization) and functional domains. .

[0170] As a specific example, this disclosure relates to TβRII fused to the Fc domain of Sequence ID No. 20. Provides a fusion protein containing polypeptide variants. If necessary, the Fc domain Asp-265, Lys-322, and Asn-434 (according to their corresponding full-length IgGs) It has one or more mutations in residues such as those that are numbered. In some cases, the patient has one or more of these mutations (e.g., the Asp-265 mutation). The mutant Fc domain has a greater ability to bind to the Fcγ receptor compared to the wild-type Fc domain. It has a decrease in [something]. In other cases, one or more of these mutations (e.g., Asn- The mutant Fc domain with the 434 mutation is more MH than the wild-type Fc domain. It has an increased ability to bind to Class C I-associated Fc receptors (FcRNs).

[0171] The different elements of the fusion protein can be arranged in any configuration that matches the desired functionality. It is understood that this is possible. For example, the TβRII polypeptide can be processed into the C-terminus of a heterogeneous domain. They may be placed at the end, or alternatively, a heterogeneous domain at the C-terminus of the TβRII polypeptide. It may be placed on the edge. The TβRII polypeptide domain and heterologous domain are fused together. They do not need to be adjacent within the protein; an additional domain or amino acid sequence can be either It may be included at the C or N-terminus of the domain, or between these domains. That's fine.

The domains are: 1) CH1 domain, CH2 domain and CH3 domain, 2) CH1 domain and CH2 domain, 3) CH1 domain and CH3 domain, 4) CH2 domain and CH3 domain, or 5) two or more domains and immunoglobulin This may include a combination of hinge regions. In a preferred embodiment, the immunoglobulin Fc region is It includes at least the immunoglobulin hinge region, the CH2 domain, and the CH3 domain, and is preferable In some embodiments, the CH1 domain is missing. In some embodiments, the immunoglobulin Fc region This is the human immunoglobulin Fc region.

[0173] In one embodiment, the class of immunoglobulin from which the heavy chain constant region originates is IgG (Igγ ) (γ subclass 1, 2, 3 or 4). Other classes of immunoglobulins, IgA ( Even if you use Igα, IgD (Igδ), IgE (Igε), and IgM (Igμ), Good. The selection of an appropriate immunoglobulin heavy chain constant region is described in U.S. Patent No. 5,541,087. This is discussed in detail in publications No. 5,726,044. The weight of certain immunoglobulins from a particular immunoglobulin class and subclass. The selection of the chain constant region sequence is considered to be within the range of skill levels in this field. The portion of the DNA construct encoding the immunoglobulin Fc region is preferably a hinged May At least a portion of the IgA, preferably the CH3 domain of Fc gamma or IgA, IgD , including at least a portion of the homologous domain in either IgE or IgM.

[0174] Furthermore, amino acid substitutions or deletions within the constant region of immunoglobulin heavy chains are permitted in this specification. The methods and compositions shown may be useful in carrying out the work. One example is the Fc receptor.

And to treat chronic kidney disease (e.g., tissue damage, inflammation and / or fibrosis) It can prevent the disease or reduce its progression and / or severity. Chronic kidney disease (CKD), also known as chronic kidney disease, is a condition that can last for months or years. This is a gradual loss of kidney function over time. Symptoms of worsening kidney function include poor overall health. This may include feeling that and experiencing a loss of appetite. In many cases, chronic kidney disease is People with kidney disease, such as those with high blood pressure or diabetes, and those with a blood relative who has CKD. It is diagnosed as a result of screening of people who are known to be at risk. The patient may develop one of its recognized complications, such as cardiovascular disease, anemia, or pericarditis. It may be confirmed at that time. Recent expert guidelines classify the severity of CKD into 5 stages. It is classified into stages, with Stage 1 being mild and usually causing little to no symptoms. Stage 5 CKD is a serious illness with a short life expectancy if left untreated. Often referred to as end-stage renal disease or end-stage renal failure, this term is now considered outdated. This is generally synonymous with nephrotic renal failure or chronic renal failure, and may include forms of dialysis, but is ideal. In general, this usually means that the patient requires renal replacement therapy equivalent to a kidney transplant. (CKD) In its early stages, it often presents with no specific symptoms, and generally involves an increase in serum creatinine or urinary protein. It is detected only as an additive. As kidney function declines, various symptoms manifest as follows: It can manifest as fluid overload and is produced by the kidneys via the renin-angiotensin system. The production of vasoactive hormones can cause blood pressure to rise, resulting in hypertension. The risk of developing the disease and / or developing congestive heart failure increases. It can accumulate, resulting in azotemia and ultimately uremia (from lethargy to pericarditis). It can lead to various symptoms, including encephalopathy. Due to this high level of systemic circulation, the urine is highly concentrated and ductile. It is excreted in phosphate sweat and crystallizes on the skin as the sweat evaporates ("urea frost"). Potassium It can accumulate in the blood (causing various symptoms, including fatigue and potentially fatal arrhythmias). Symptomatic hyperkalemia. Hyperkalemia is usually characterized by a glomerular filtration rate of 20-25 mg / L. The onset of symptoms does not occur until potassium levels drop to less than l / min / 1.73m2, and at the time of onset, renal potassium excretion is impaired. Potassium excretion capacity is reduced. Hyperkalemia in CKD is due to acidic blood (potassium extracellular transfer). It can be exacerbated by (leading to) and insulin deficiency. Erythropoietin It can also reduce synthesis, leading to anemia. This can progress from mild edema to fatal pulmonary edema. Various symptoms of excess body fluid volume can occur. Hyperphosphatemia caused by decreased phosphate excretion is Generally, it can occur after a decrease in glomerular filtration. Hyperphosphatemia is associated with an increased cardiovascular risk. This directly stimulates vascular calcification. Hypocalcemia may also become apparent, which is... Generally, it is caused by stimulation of fibroblast growth factor 23. Osteocytes use the enzyme 1-al pha-hydroxylase (1,25-dihydroxy of 25-hydroxycholecalciferol) It is a potent inhibitor of (which is involved in the conversion to vitamin D3), and is involved in increasing the production of FGF23. It agrees. Later, this led to secondary hyperparathyroidism, renal osteodystrophy, and vascular It progresses to calcification, and vascular calcification further impairs cardiac function. Metabolic acidosis ( This occurs due to the accumulation of sulfates, phosphates, uric acid, etc., and the excessive action of acid on enzymes. This can cause changes in enzyme activity, and hyperpotassium can result from excessive acid (acidic blood). The promotion of mucinosis can also lead to increased excitability of the pericardium and neuronal membranes. Sidosis is caused by a decrease in the ability of cells in the proximal tubules to produce sufficient ammonia. Iron deficiency anemia, in particular, can occur as kidney function declines, and its prevalence increases with age. It is frequently seen in those requiring hydrodialysis. Iron deficiency anemia is multifactorial in terms of its cause. However, these include increased inflammation, decreased erythropoietin, and hyperuricemia, which contribute to bone marrow suppression. Connected. People with CKD suffer from rapidly progressive atherosclerosis, and the general public Patients with chronic kidney disease (CKD) and cardiovascular disease are more likely to develop cardiovascular disease than others. Some individuals tend to have a significantly worse prognosis than those who suffer from cardiovascular disease alone.
