 AB    We investigated the cellular requirement for primary in vitro generation
       of cytotoxic T-lymphocytes (CTL) in BALB/c spleen cells against
       Ld-binding self-peptide p2Ca. Depletion of CD4+ T-cells in vitro by
       pretreatment with anti-CD4 monoclonal antibody (mAb) and complement or
       in vivo by administration of anti-CD4 mAb abrogated generation of CTL.
       Depletion of adherent cells by passing spleen cells through a nylon wool
       (NW) column also abrogated generation of CTL. Addition of peritoneal
       exudate cells (PEC) to spleen cells passed through the NW column
       restored CTL generation. These findings indicate that both CD4+ T-cells
       and antigen-presenting cells (APC) were necessary for CTL generation.
       Treatment of PEC with paraformaldehyde (PFA), but not mitomycin-C (MMC)
       abrogated their ability to restore CTL generation when mixed with spleen
       cells from the NW column, suggesting that an endocytic pathway could be
       involved in presentation of p2Ca on APC.
