abstract：:Aging diminishes the amount of phosphotyrosine in the CD3zeta chains of resting and activated mouse CD4 T cells by about threefold and might therefore be expected to a corresponding decline in Zap-70 association with CD3zeta and in Zap-70 kinase function in CD3zeta complexes. We show here that aging leads, unexpectedl...
