摘要:
The present invention is directed to a peptide, multimer, conjugate, analog, derivative or mimetic thereof that inhibits the activity of VISTA. The invention further contemplates therapeutic use of the VISTA antagonist peptide, multimer, conjugate, derivative or mimetic thereof, including treating or preventing cancer, bacterial infections, viral infections, parasitic infections and fungal infections, as well as research uses of the antagonist.
摘要:
The present invention relates to a fusion proteins comprising regulatory T cell protein, VISTA (V-domain Immunoglobulin Suppressor of T cell Activation (PD-L3) and an immunoglobulin protein (Ig), preferably also containing a flexible linker intervening the VISTA and Ig Fc polypeptide. The invention also provides the use of VISTA polypeptides, multimeric VISTA polypeptides, VISTA-conjugates (e.g., VISTA-Ig), and VISTA antagonists for the treatment of autoimmune disease, allergy, and inflammatory conditions, especially lupus, multiple sclerosis, psoriasis, psoriatic arthritis, multiple sclerosis, Crohn's disease, inflammatory bowel disease and type 1 or type 2 diabetes.
摘要:
A method of treating lupus using anti-gp39 antibodies or fragments is provided. Such treatment has been shown to reverse disease, and in particular lupus-associated kidney disease, the major killer of lupus subjects.
摘要:
Method for the treatment of multiple sclerosis and other T cell mediated autoimmune disorders is described. The method involves administering to a subject a therapeutically effective amount of an antagonist of a receptor on a surface of a T cell which mediates contact dependent helper effector functions, for example, an anti-gp39 antibody.

摘要:
The present disclosure relates to compositions and therapeutic methods for activating an immune response in a patient in need thereof. In a preferred embodiment, the subject methods and compositions are able to antagonize the activity of VISTA, a naturally occurring “checkpoint” protein which contributes to immune tolerance, optionally in combination with an antagonist of a second checkpoint pathway such as PD-1. For example, such methods and compositions may be suitable for preventing and treating colon cancer or another cancer. An exemplary VISTA antagonist, specifically, an anti-VISTA antibody, is demonstrated herein to activate an immune response against cancer cells in vitro and in vivo, thereby conferring protective anti-tumor immunity which decreased tumor burden. Additionally, an additive benefit was observed when a VISTA antagonist was used in combination with a second checkpoint protein antagonist, specifically, an antibody against PD-1 ligand (PD-L1).
