We studied the role of phospholipids and nitric oxide in expression of the suppressor activity of splenic macrophages induced by Mycobacterium avium‐intracellulare complex infection (MAIC‐induced macrophages) in mice against mitogenic response of concanavalin A (Con A)‐stimulated splenocytes (SPC) as follows. First, phosphatidylserine (PS) and phosphatidylinositol were found to suppress Con A‐induced mitogenesis of SPC via inhibition of IL‐2 production and acquisition of IL‐2 reactivity in Con A‐stimulated T cells. The mitogenesis‐inhibitory activity of PS was increased when SPC were cultured under mildly acidic condition (pH 6.3). When SPC were pretreated with PS for 24 h prior to Con A blastogenesis, their mitogenic response was irreversibly abrogated. Second, NG‐monomethyl‐l‐arginine, an inhibitor of nitric oxide (NO) synthase, was found to attenuate in part the expression of the suppressor activity of MAIC‐induced macrophages. Third, reactive nitrogen intermediates (RNI) including NO generated from acidified NO−2 exerted potent inhibitory activity against SPC mitogenic response, and the suppressive activity of RNI was significantly augmented by the combination with PS. These findings indicate that phospholipids and RNI play an important role in the expression of suppressor activity of MAIC‐induced macrophages as the effector molecules.
