Abstract

The invention provides agonistic anti-human VISTA antibodies and antibody fragments. These agonist antibodies and antibody fragments may be used to potentiate or enhance or mimic VISTA's suppressive effects on T cell immunity and thereby suppress T cell immunity. These agonist antibodies and antibody fragments are especially useful in the treatment of autoimmunity, allergy, inflammatory conditions, GVHD, sepsis and transplant recipients. Screening assays for identifying these agonists are also provided.

Claims

exact text as granted — not AI-modified
1 . A method of treating or preventing an autoimmune, allergic or inflammatory condition comprising administering to a patient in need thereof a therapeutically or prophylactically effective amount of an isolated antibody or antibody fragment thereof comprising an antigen binding region that specifically binds to human V-domain Ig Suppressor of T cell Activation (human VISTA), wherein the antibody or antibody fragment agonizes or promotes one or more of the effects of VISTA on immunity.
