HAVCR2 is a 281aa Type-1 Th1- specific cell surface glycoprotein expressed on terminally differentiated CD4+Th1 and CD8+Tc1 cells. It consists of an IgV-region like domain and a mucin-like domain in the extracellular region and a conserved Tyrosine phosphorylation motif in the cytoplasmic region. HAVCR2 regulates macrophage activation thereby down regulating aggressive Th-1 mediated immune responses and facilitates in the development of immune tolerance. It plays an important role in the induction of autoimmune diseases by regulating macrophage activation. Pathological significance of HAVCR2 has been attributed to Experimental autoimmune encephalomyelitis (EAE), a Th-1 dependent autoimmune disease.
