ZAP-70 directly enhances IgM signaling in chronic lymphocytic leukemia

29 Oct 2004

Abstract excerpt

Chronic lymphocytic leukemia (CLL) B cells that express unmutated immunoglobulin heavy-chain variable region genes (IgV(H)) generally express ZAP-70, in contrast to normal B cells or most CLL cases with mutated IgV(H). Following IgM ligation, ZAP-70+ CLL cells had significantly higher levels of phosphorylated p72(Syk), BLNK, and phospholipase-Cgamma (PLCgamma) and had greater[Ca2+]i flux than did ZAP-70-negative...
