Human peripheral blood mononuclear cell (MN) proliferation and lymphokine production induced by mitogen could be inhibited by heat killed whole mycobacteria. The inhibition was induced by a wide variety of mycobacteri but not by other Gram-positive or Gram-negative organisms or by latex particles. Proliferation and lymphokine production by adherent cell-depleted lymphocytes was not inhibited by these organisms. Adherent cells treated with mycobacteria had the ability to inhibit lymphocyte blastogenesis when co-cultured with the lymphocytes. the inhibitory effect of these adherent cells was due to the release of a heat stable, nondialyzable suppressor cells. These latter cells, which were T gamma cells, could inhibit the blastogenic ability of normal lymphocytes activated by mitogens. The results suggest that in situations of high mycobacterial load, adherent cells are activted to release a suppressor factor that will activate lymphocytes to become suppressor cells. This mechanism may explain the anergy associated with lepromatous leprosy or advanced tuberculosis.
