title: Frequency of herpes simplex virus-specific murine cytotoxic T lymphocyte precursors in mitogen- and antigen-driven primary in vitro T cell responses.
abstract: The aim of this study was to assess and to compare the frequencies and specificities of herpes simplex virus (HSV)-specific cytotoxic T lymphocyte precursors (CTL-p) in mitogen (concanavalin A)-activated splenic T cells, as well as in antigen-activated splenic T cells of normal nonimmunized mice. In the mitogen-driven system one of 130 T cell blasts developed clonal progenies able to lyse specifically HSV-infected syngeneic targets. In the antigen-driven system HSV-specific CTL-p could be detected in normal lymphocytes provided the stimulator cells used were enriched for dendritic cells and pulsed with high concentrations of heat-inactivated HSV. Depending on the mouse strain used, the frequencies of HSV-specific CTL-p ranged from 1/500 to 1/10,000 in normal mice. Upon antigen priming within local lymph node cells, an increase of frequencies from 1/500 to 1/170 was observed in CBA/Ca mice.
