背景 | B7-H7, also known as HHLA2 (HERV-H LTR-associating 2), is a member of the B7 family of immune regulatory proteins (1, 2). Mature human B7-H7 consists of a 322 amino acid (aa) extracellular domain (ECD) with three immunoglobulin-like domains, a 21 aa transmembrane segment, and a 49 aa cytoplasmic domain (3-5). B7‑H7 is constitutively expressed on monocytes and is up-regulated by LPS and IFN-gamma stimulation. It is expressed on LPS/IFN-gamma treated B cells but not on resting B cells (5). B7-H7 binds to cell surface determinants on resting and mature T cells, B cells, and monocytes as well as on immature and mature dendritic cells (5). Soluble B7-H7 inhibits the proliferation of activated CD4+ and CD8+ T cells and their production of IFN-gamma, TNF-alpha, IL-5, IL-10, IL-13, IL-17A, and IL-22 (5). |

Detection of B7-H7/HHLA2 in HEK Human Cell Line Transfected with Human B7-H7/HHLA2 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with either (A) human B7-H7/HHLA2 or (B) irrelevant transfectants and eGFP was stained with Mouse Anti-Human B7-H7/HHLA2 Alexa Fluor® 647‑conjugated Monoclonal Antibody (Catalog # FAB80841R). Quadrant markers were set based on control antibody staining (Catalog # IC002R). View our protocol for Staining Membrane-associated Proteins. |
