Counterregulation by the coreceptors CD19 and CD22 of MAP kinase activation by membrane immunoglobulin.

abstract：:Clonal selection theories postulate that lymphocyte fate is regulated by antigen receptor specificity. However, lymphocyte apoptosis is induced through nonantigen-specific receptors such as Fas (CD95/APO-1) or TNFR. We define a selective TCR that controls apoptosis by Fas or TNFR stimulation. Variant ligands can deliv...
