The antirejection eicosanoids--PGE2, (PGD2), and PGI2--have an attenuating effect on T-cell proliferation by inhibition of IL-1, IL-2, and class II antigen expression on macrophages, and the prorejection eicosanoids--TXA2, LTB4, LTC4, and LTD4--enhance T-cell proliferation. LTB4 stimulates IL-1 and IL-2 formation and expression of IL-2 receptor. The mechanism of enhancement of T-cell proliferation by TXA2 has not been demonstrated. LTC4 and LTD4 promote gamma-interferon release and can replace IL-2 as a stimulator of gamma-interferon. PAF at high concentrations inhibits lymphocyte proliferation. The eicosanoids interfere with the same mechanisms as CsA and corticosteroids on T-cell clonal expansion. In experimental organ transplantation, corticosteroids can be replaced by compounds preventing the formation or expression of the prorejection eicosanoids or analogs of antirejection eicosanoids as well as by PAF antagonists. In addition, these drugs exert synergistic effect with CsA and azathioprine.

Immune and inflammatory responses involve a whole array of cells and cell products which interact and mutually regulate each other. Many of these interactions are mediated by cytokines acting through specific receptors. Furthermore, lipid mediators such as PAF and the arachidonic acid metabolites LTB4 and PGE2 are known to affect several of the mechanisms involved in the regulation of the immune and inflammatory responses. In this paper, we review recent data from our laboratory illustrating the differential regulation of IL-6 and TNF alpha production and IL-2 receptor alpha and beta expression by these lipid mediators. We show that the regulation of these genes is both transcriptional and post-transcriptional, and that LT and PG can also be involved as second messengers in these regulatory processes.
