    basic FUNCTION
  • is not only a phagocytic receptor, but also a potent inhibitor of the alternative pathway convertases
  • T cells can opposite T cell hyporesponsiveness through dampening VSIG4 inhibitory signals from macrophages and thus maintain their anti-viral function in chronic HBV infection (CHB)
  • B7 family-related macrophage protein that has the capacity to inhibit T-cell activation, and has a potential role in the development of lung cancer
  • acts as a co-inhibitory ligand to negatively regulate T cell proliferation and cytokine production, and its expression is restricted to macrophages
  • functions as a macrophage pattern recognition receptor to directly bind and capture blood-borne Gram-positive bacteria
  • macrophage-associated VSIG4 plays a negative role in helper T cell-dependent isotype switching by inhibiting helper T cell activation and differentiation, and suppressing the isotype switching-inducing cytokine production in antigen-primed CD4(+) helper T cells
  • dual functionality: a negative regulator of T cell activation and a receptor for the complement components C3b and C3c
  • B7 family-related macrophage protein with the capacity to inhibit T-cell activation, having a potential role in cancer
  • inhibits proinflammatory macrophage activation by reprogramming mitochondrial pyruvate metabolism

  • is a strong negative regulator of T cell proliferation and IL2 production
  • VSIG4 signals induce anti-intracellular bacterial phagosome activity in a CLIC3-dependent manner
  • PRKCA promotes the downregulation of VSIG4 and upregulation of ITGAM expression and TNF and IL6 production, a mechanism that may promote inflammation
