The T V alpha and V beta cell specificities repertoire usage in aging subjects was studied by the use of seven different monoclonal antibodies specific for defined regions of the T cell receptor (TCR). Except for the V beta 8 subfamily, no differences were observed in the frequency of T cells bearing selected V alpha beta epitopes, between old and control subjects.
