Clone REA301 recognizes the mouse CD101 antigen, a type I transmembrane glycoprotein also known as immunoglobulin superfamily member 2 (IgSF2) or V7. CD101 is expressed on monocytes, granulocytes, dendritic cells (DCs), and activated T cells. In humans CD101 inhibits the proliferative response of T cells to allogeneic cells or immobilized anti-CD3 antibody, suggesting that engagement of CD101 can antagonize TCR/CD3-mediated lymphocyte activation. Moreover, human peripheral CD8+ T cells that express CD101 and CD103 display suppressive function after activation with intraepithelial cells or placental trophoblasts. In addition to its role on T cells, triggering CD101 on human cutaneous DCs inhibits T cell proliferation via interleukin 10 (IL-10) production, suggesting that the CD101 molecule may be involved in tolerance induction. Studies in mice showed that cell surface expression of CD101 is highly correlated with functional suppressor activity within CD4+ CD25+ T regulatory cells both in vitro and in vivo .
Additional information: Clone REA301 displays negligible binding to Fc receptors.
