Description

The recombinant human VSIG4 protein was used as the immunogen to produce the VSIG4 monoclonal antibody. Obtaining the DNA sequence of the VSIG4 monoclonal antibody by sequencing the cDNA and then cloning the gene into a plasmid vector. The plasmid vector containing the VSIG4 monoclonal antibody gene is transfected into the host cell using a suitable transfection method. The VSIG4 recombinant monoclonal antibody underwent affinity-chromatography purification. It is only reactive with the human species. Its specificity has been tested in ELISA. It can bind to the recombinant human VSIG4 protein (CSB-MP896869HU) with the EC50 of 51.14-68.73 ng/mL.

The VSIG4 protein mainly regulates immune responses by interacting with immune cells such as T cells and macrophages. It is known to act as a co-stimulatory molecule, enhancing T cell activation, and also as an inhibitory molecule, suppressing the function of macrophages. VSIG4 has been shown to play a role in the regulation of autoimmune responses, tumor immunity, and infectious diseases. It is also involved in the clearance of apoptotic cells and the maintenance of tissue homeostasis.

Target Background

Function
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
