    摘要: The present invention relates to a novel regulatory T cell protein. This protein, designated PD-L3 OR VISTA resembles members of the PD-L1 family, identified a novel and structurally-distinct, Ig-superfamily inhibitory ligand, whose extracellular domain bears homology to the B7 family ligand PD-L1. This molecule is designated as PD-L3 OR VISTA or V-domain Immunoglobulin Suppressor of T cell Activation (VISTA). Expression of VISTA is primarily within the hematopoietic compartment and is highly regulated on myeloid APCs and T cells. Therapeutic intervention of the VISTA inhibitory pathway represents a novel approach to modulate T cell-mediated immunity for the treatment of a wide variety of cancers, e.g., ovarian, bladder cancer and melanomas. Also, VISTA proteins, especially multimeric VISTA proteins and antibodies may be used to suppress T cell immunity in autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis and artritic conditions such as RA.

    摘要: The present invention relates to novel regulatory T cell proteins. One protein, designated PD-L3, resembles members of the PD-L1 family, and co-stimulates αCD3 proliferation of T cells in vitro. A second, TNF-like, protein has also been identified as being upregulated upon αCD3/αGITR stimulation. This protein has been designated Treg-sTNF. Proteins, antibodies, activated T cells and methods for using the same are disclosed.In particular methods of using these proteins and compounds, preferably antibodies, which bind or modulate (agonize or antagonize) the activity of these proteins, as immune modulators and for the treatment of cancer, autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis is disclosed
