CD276 (B7H3) is a type I transmembrane glycoprotein expressed on dendritic cells, osteoblasts, sinonasal epithelium, and upon activation (by inflammatory cytokines) in monocytes, NK cells, T cells and B cells. Although it has been described also as a costimulatory ligand, its major role seems to be inhibitory. It regullates T cell proliferation and functions, and may provide certain tumors with protection against NK cells. CD276 can be used as a marker of neuroblastoma cells in the bone marrow, which is the primary site of neuroblastoma relapse.
