Target Background

(From Uniprot)
Phagocytic receptor, strong negative regulator of T-cell proliferation and IL2 production. Potent inhibitor of the alternative complement pathway convertases.
Gene References into Functions
  1. Soluble VSIG4 levels are associated with the progression and recurrence of ovarian cancer, indicating that soluble VSIG4 may be used as a potential biomarker for predicting tumor prognosis. PMID: 28498255
  2. VSIG4 signaling provides an anti-immune evasion mechanism that prevents the outgrowth of intracellular bacteria in macrophages PMID: 27440002
  3. The VSIG4 upregulation by LMP1 was regulated at the transcriptional level via the NF-kB signaling axis. PMID: 28859984
  4. VSIG4 expression is significantly upregulated in human masticatory mucosa during wound healing PMID: 28005267
  5. we concluded that let-7g-5p inhibits epithelial-mesenchymal transition (EMT) consistent with reduction of glioma stem cell (GSC) phenotypes by targeting VSIG4 in glioblastoma. PMID: 27634309
  6. Data indicate that rotein kinase calpha (PKCalpha) plays a role in downregulating complement receptor Ig (CRIg coded by V-set and Ig domain-containing protein 4 VSIG4) expression. PMID: 25687755
  7. complement receptor of the immunoglobulin superfamily-L-factor H protects glomerular mesangial cells from complement-mediated injury and proliferative lesions PMID: 25114177
  8. we identified VSIG4 as a potential diagnostic marker of severe preeclampsia. The determination of this gene may improve the prognostic assessment of severe preeclampsia. PMID: 24349325
  9. Data indicate that massive V-set and Ig domain-containing 4 VSIG4(+) cell infiltration throughout the non-small-cell lung cancer samples. PMID: 24862966
  10. we showed that a complement receptor of the Ig superfamily (CRIg, also known as Z39Ig), a receptor for complement fragments (C3b and iC3b), was expressed on a subset of intestinal macrophages in murine and human large intestine PMID: 21768202
  11. These results suggest that T cells can opposite T cell hyporesponsiveness through dampening Z39Ig inhibitory signals from macrophages and thus maintain their anti-viral function in chronic hepatitis B. PMID: 20399148
  12. hVSIG4 recombinant adenovirus-transfected DCs suppress T cell proliferation, cytokine production and activation marker expression with PMID: 19914289
  13. Results report the identification and characterization of a Complement Receptor of the Immunoglobulin superfamily, CRIg, that binds complement fragments C3b and iC3b. PMID: 16530040
  14. These data indicate that the macrophage Z39Ig is involved in the pathogenesis of inflammatory diseases through chemokine induction, which will promote the migration of inflammatory cells into the lesion area, and MMP-9 induction. PMID: 16882875
  15. The specific expression of VSIG4 on resting macrophages suggests that VSIG4 may be important for the maintenance of T cell unresponsiveness in healthy tissues. PMID: 17016562
  16. CRIg is not only a phagocytic receptor, but also a potent inhibitor of the alternative pathway convertases PMID: 17051150
