B7-H4 is a B7 family member that negatively regulates T cell immunity by inhibiting of T cell proliferation, cytokine production and cell cycle progression. In vitro, B7-H4 inhibits CD4+ and CD8+ T cell proliferation, cytokine production and generation of alloreactive cytotoxic T cells (CTLs). In vivo, blockade of endogenous B7-H4 by specific monoclonal antibody promotes T cell responses. B7-H4 ia an important negative regulator of innate immunity through growth inhibition of neutrophils. B7-H4 is expressed on some tumor cancer cells. The role of B7-H4 in tumor progression may be to transform precancerous cells and then protect them from immunosurveillance. - Protein. The extracellular domain of human B7-H4 (aa 29-258) is fused to the N-terminus of the Fc region of rabbit IgG. Source: HEK 293 cells. Endotoxin content: <5EU/mg protein (LAL test; Lonza). Lyophilized from 0.2microm-filtered solution in PBS. Purity: >98% (SDS-PAGE).
