Abstract：
:Phagocytosis of latex beads by peritoneal macrophages was examined by means of flow cytometry (FCM). This assay revealed that adrenocorticotropic hormone (ACTH) suppressed phagocytosis in a dose-dependent manner. ACTH (1-24) was more suppressive than ACTH (1-39). Control phagocytosis was partially suppressed in Ca(2+)-free solution. Phagocytosis was suppressed by ACTH in this solution to the same degree as in the normal solution. Suppression by ACTH was reduced in phosphodiesterase inhibitor-containing solution. These results suggest that (1) ACTH suppresses extracellular Ca(2+)-dependent and -independent phagocytosis, (2) the suppression is not mediated by cAMP and (3) the inhibition of macrophage phagocytosis by ACTH is one of the mechanisms that modulate immune responses in stressful situations.
