Abstract: The disclosure features fusion proteins that are conditionally active variants of IL-2. In one aspect, the full-length polypeptides of the invention have reduced or minimal cytokine-receptor activating activity even though they contain a functional cytokine polypeptide. Upon activation, e.g., by cleavage of a linker that joins a blocking moiety, e.g., a steric blocking polypeptide, in sequence to the active cytokine, the cytokine can bind its receptor and effect signaling.

Abstract: This invention provides for a fusion protein between an IL2??? Selective Agonist protein (IL2 Selective Agonist) and a IgG Fc protein using a linker. The IL2 Selective Agonist moiety provides a therapeutic activity by selectively activating the IL2??? form of the receptor, thus selectively stimulating Tregs. The Fc moiety provides a prolonged circulating half-life compared to the circulating half-life of IL-2 or an IL2SA protein.
Abstract: A monoclonal antibody, or antigen-binding portion thereof is provided that specifically binds to a region on a mammalian IL-31 protein involved with interaction of the IL-31 protein with its co-receptor, wherein the binding of said antibody to said region is impacted by mutations in a 15H05 epitope binding region selected from: a region between about amino acid residues 124 and 135 of a feline IL-31 sequence represented by SEQ ID NO: 157 (Feline_IL31_wildtype); a region between about amino acid residues 124 and 135 of a canine IL-31 sequence represented by SEQ ID NO: 155 (Canine_IL31); and a region between about amino acid residues 118 and 129 of an equine IL-31 sequence represented by SEQ ID NO: 165 (Equine_IL31). Such antibodies can be in the form of veterinary compositions useful for treating IL-31-mediated disorders in cats, dogs, or horses.

Abstract: Disclosed herein are compositions and methods for preparation and use of protein therapeutics, and more particularly protein clusters or backpacks having a plurality of therapeutic protein monomers reversibly crossed-linked by biodegradable linkers.
Abstract: Provided herein are dimeric IL-7-Fc fusion proteins that include Fc domains and one or more IL-7s. Also provided herein are variant IL-7s with modifications to reduce heterogeneity and/or reduced affinity/potency. Such variant IL-7s are useful, for example, in the subject dimeric IL-7-Fc fusion proteins. The dimeric IL-7-Fc fusion proteins can be used for applications where increased IL-7 activity is useful, for example, for increasing the proliferation of lymphocyte populations in mounting an anti-tumor response in a subject in need thereof.

Abstract: Provided is a fusion protein comprising IL-2 protein and CD80 protein. A fusion protein comprising CD80 fragment, immunoglobulin Fe, and an IL-2 variant can activate immune cells, such as natural killer cells, and at the same time, can control immune cell regulatory activity of regulatory T cells. Therefore, a pharmaceutical composition comprising the fusion protein as an active ingredient is very industrially useful in that such pharmaceutical composition can increase immune activity in the body, and thus can be effectively used against infectious diseases as well as cancer.
Abstract: Disclosed are new recombinant isoforms of human-like lubricin or PRG4 glycoprotein having outstanding lubrication properties and a novel glycosylation pattern, and methods for their manufacture at high levels enabling commercial production.
Abstract: The present invention provides methods for treating, preventing or reducing the severity of allergic reactions. The present invention also provides methods for enhancing the efficacy and/or safety of an allergen-specific immunotherapy (SIT) regimen. The methods of the present invention comprise administering to a subject in need thereof a therapeutic composition comprising an interleukin-4 receptor (IL-4R?) antagonist such as an anti-IL-4R? antibody.

Abstract: The present application relates to induction of a Treg phenotype in mammalian naïve CD4+ T cells. In certain embodiments, the methods and compositions described can be applied as methods to treat autoimmune disorders or transplant complications (e.g., lupus and graft-versus-host disease) and may be used in combination with, but do not require, systemic immune suppression, such as a chemotherapeutic agent. In particular, embodiments of the disclosure can utilize transforming growth factor-beta 2 (TGFB2), molecules that stimulate the production of TGFB2, inhibitors of molecules that suppress production of TGFB2, or molecules that effect the function of TGFB2 to induce a Treg phenotype in naïve CD4+ T cells from a mammal. Provided herein are embodiments and examples demonstrating the production of Treg cells, as well as the application of Treg cells in modulating the inflammatory response present in certain diseases.

Abstract: A heterodimeric Fc-fused protein and a pharmaceutical composition comprising the heterodimeric Fc-fused protein are disclosed. The heterodimeric Fc-fused protein includes first and second Fc regions of an immunoglobulin heavy chain constant region (Fc) pair and in which IL-21 is bound to at least one of the N-terminus or the C-terminus of the first Fc region and/or the second Fc region, wherein CH3 domains of the first Fc region and the second Fc region are mutated such that the formation of a heterodimer is promoted. When the heterodimeric Fc-fused protein is used, an in vivo half-life of IL-21 included in the heterodimeric Fc-fused protein may be significantly increased.
