The concentration of cAMP increases in human mononuclear leukocytes after exposure to salmon calcitonin (SCT). This response is lost when the cells are separated into adherent (monocytic) and nonadherent (lymphocytic) cells, al-though the appropriate response to prostaglandin E2 remains in both groups. Adherent and nonadherent cells, each cultured alone for 16 h, do not regain the SCT response. Coculturing adherent and nonadherent cells together for 16 h restores the SCT response in the lymphocytes. The addition of a cyclooxygenase inhibitor to this culture system prevents development of the SCT response. The SCT response may be induced in nonadherent cells by culturing them for 16 h in medium previously conditioned by the growth of mixed mononuclear leukocytes.
