MHC-unrestricted expression of the suppressor activity by M. intracellulare-induced macrophages (MI-Mφs) against target T cells. Con A-stimulated spleen cells (SPCs) (2·5 × 105) from BALB/c (H-2d), C57BL/6 (H-2b) or CBA/JN (H-2k) mice were co-cultured with MI-Mφs (2 × 104/well) from BALB/c mice. Each bar indicates the mean ± s.e.m. (n = 4).
