Distinct subpopulations of macrophages or differently activated macrophages display various functions in immune reactions. Some of their activities depend on specific sets of factors (i.e., cytokines and eicosanoids) produced by activated macrophages. We have studied the ability of murine (CBA/ca) peritoneal macrophages to selectively release tumor necrosis factor alpha (TNF-alpha), interleukin 1 (IL-1), and IL-6. We have found that the priming of cells (Mo) with different stimulants (thioglycolate vs. LPS) induces the release of particular cytokines by reactivated macrophages. The increased release of TNF-alpha correlates with lower levels of IL-1 and IL-6. We have also found that prostaglandin E2 (PGE2) and prostacyclin (PGI2) have opposing effects on the production of two of these cytokines. The release of TNF-alpha is inhibited by prostaglandins, whereas increased levels of PGE2 and PGI2 correlate with higher levels of IL-6.
