| abstractText | The expression of Epa-1, a tissue-restricted non-major histocompatibility complex (MHC) alloantigen, on CBA epidermal cells (EC), fibroblasts (FB), and macrophages (M phi) was investigated using bulk-cultured and clonally-derived anti-Epa-1 cytotoxic T lymphocytes (CTL). Epa-1 was readily detected on freshly trypsinized and 24-hr-cultured EC, and on skin FB cultured for 1-3 weeks. In contrast, fresh peritoneal (PE) M phi were specifically resistant to Epa-1 CTL but became susceptible after 12-24 hr in culture. Epa-1 expression by PE M phi also could be induced in vivo by M phi-activating agents such as concanavalin A or Bacillus Calmette-Guerin (BCG), but not by the sterile inflammatory agents peptone broth or thioglycolate, suggesting a correlation between Epa-1 phenotype and M phi activation. From this and from parallel studies of spleen cell M phi it is concluded that Epa-1 may be a strain-specific marker for activated M phi in the mouse, as well as an inducible histocompatibility antigen in vivo. |
