The kinetics of generation of influenza-specific cytotoxic T-lymphocyte precursor cells.
A dramatic increase in the number of restimulatable (memory) cytolytic T-cell precursors (CTLps) has been demonstrated to occur 2 to 4 days postimmunization. By 4 or at the latest 6 days following in vivo priming, the frequency of restimulatable influenza-specific CTLps has reached that characteristic of a memory response. This indicates that the proliferative events which give rise to memory CTLps occur earlier than might have been expected and in fact are completed prior to the cessation of othe primary CTL response. Such information may have important significance to future immunomodulatory efforts aimed at perturbing the establishment of T-cell memory in vivo.
