title: Antigen-dependent proliferation of cloned continuous lines of H-2-restricted influenza virus-specific cytotoxic T lymphocytes.
abstract: The antigenic requirements for in vitro proliferation of several cloned continuous lines of H-2-restricted influenza virus-specific cytotoxic T lymphocytes (CTL) has been examined. The cloned CTL lines were established from individual splenic CTL precursors obtained from A/JAPAN/305/57 (H2N2)-immune F1 (C57BL/6 X BALB/c) donors. The lines were isolated (by limiting dilution in liquid culture) and expanded in the presence of A/JAPAN/305/57-infected irradiated syngeneic (F1) spleen cells and T cell growth factor (TCGF) of rat spleen origin. Optimal proliferation (and long-term in vitro cultivation) of these H-2-restricted CTL lines required both specific antigenic stimulation in the form of virus-infected syngeneic spleen cells and an exogenous source of TCGF. In addition, the antigenic requirements for proliferation of these lines directly reflected the pattern of H-2-restricted influenza virus-specific recognition at the level of target cell recognition and lysis.
