Rat lymphocyte function associated antigen 3,LFA-3 ELISA Kit

Product name:Rat lymphocyte function associated antigen 3,LFA-3 ELISA Kit
Description:
T cells require a signal induced by the engagement of the T cell receptor and a “costimulatory” signal(s) through distinct T cell surface molecules for optimal T cell expansion and activation. Many cell-bound receptor-ligand pairs have now been shown to be involved in T cell co-stimulation including CD58/CD2 in humans and CD48/CD2 in mice and rats. CD58, also known as lymphocyte function-associated antigen (LFA-3), is a 210 amino acid protein that belongs to the CD2 family of the immunoglobulin superfamily. No mouse or rat homolog of CD58 has as of yet been identified. CD58 has only one known ligand, CD2. CD2 is expressed on T cells, NK cells and Dendritic cells.2 - 4 CD2 ligation by CD58 has been shown to mediate T cell adhesion, T cell activation, T cell cytokine production and T cell and NK cells cytotoxic activity.1, 3, 5, 6 In dendritic cells, CD2 engagement increases MHC Class II, CD40, CD80, CD86, CD58 and CCR7 and induces IL-1β IL-12 cytokine secretion.
