Target Data

Function	May participate in the regulation of T-cell-mediated immune response. May play a protective role in tumor cells by inhibiting natural-killer mediated cell lysis as well as a role of marker for detection of neuroblastoma cells. May be involved in the development of acute and chronic transplant rejection and in the regulation of lymphocytic activity at mucosal surfaces. Could also play a key role in providing the placenta and fetus with a suitable immunological environment throughout pregnancy. Both isoform 1 and isoform 2 appear to be redundant in their ability to modulate CD4 T-cell responses. Isoform 2 is shown to enhance the induction of cytotoxic T-cells and selectively stimulates interferon gamma production in the presence of T-cell receptor signaling.

PMID: 30132557 Tumor B7-H3 expression was significantly higher in immunocompetent vs. immunosuppressed patients, largely driven by very low expression in HIV+ patients. PMID: 29484464 Colorectal cancer (CRC) patients expressing both high B7-H3 and high B3GALT4 contributed to a significant decrease in overall survival. The expression of B3GALT4 in CRC is positively correlated with B7-H3 expression in vitro. B7-H3/B3GLAT4 may be used as dual prognostic biomarkers for CRC. PMID: 30131660 this study shows reduced sB7-H3 expression in the peripheral blood of systemic lupus erythematosus patients PMID: 29423417 High B7-H3 expression is associated with cervical cancer invasiveness. PMID: 28627681 IDH1 and B7H3 cannot be used as independent prognostic factors, co-expression of IDH1 and B7H3 significantly correlated with the prognosis of CRC patients and may serve as a combined predictive marker.
