RESUMO
Activation of both T and B lymphocytes through their membrane receptors for antigen is known to induce breakdown of inositol phospholipids. In addition, T cell activation by antigen is accompanied by increased protein tyrosine phosphorylation of components of the T cell antigen receptor. We now provide evidence that B cell activation through membrane immunoglobulin is also coupled to stimulation of protein tyrosine kinase activity. One potential candidate for a B lymphocyte protein tyrosine kinase is an 80 kd molecule that is itself phosphorylated at tyrosine residues in response to stimulation with anti-immunoglobulin antibodies.
