Zusatzinfos

The beta(2) integrin LFA-1 is an important cell-cell adhesion receptor of the immune system. Evidence suggests that the molecule also participates in signaling and co-stimulatory function. We show here that clustering of the intracellular domain of the beta(2) chain but not of the alpha(L)- or beta(1)-cytoplasmic domains, respectively, triggers intracellular Ca(2+) mobilization in Jurkat cells. A beta(2)-specific NPXF motif, located in the C-terminal portion of the beta(2) tail, is required for Ca(2+) signaling, and we show that this motif is important for the induction of allo-specific target cell lysis by cytotoxic T cells in vitro. Significantly, the Ca(2+)-signaling capacity of the beta(2) integrin is abrogated in T cells that do not express the T cell receptor but may be reconstituted by co-expression of the T cell receptor-zeta chain. Our data suggest a specific function of the cytoplasmic domain of the beta(2) integrin chain in T cell signaling.
