EFFECT OF LEUKOTRIENES C4 AND D4 ON PROSTAGLANDIN I2-LIBERATION FROM HUMAN LYMPHATICS

---

Abstract

Whereas prostaglandin I₂ (PGI₂), a major metabolite of human lymphatics, does not itself affect lymphatic contractility significantly, it is able to counterbalance the contractile response to thromboxane and leukotrienes. We now demonstrate that leukotrienes C₄ and D₄ evoke a dose-dependent increased production of PGI₂ from human lymphatics. It is likely that leukotrienes either exert a contractile rhythmic effect on human lymphatics or, alternatively, evoke increased PGI₂-formation which relaxes human lymphatics. These mechanisms may be of local importance in regulating lymphatic "tone" at sites of inflammation as leukotrienes are liberated from activated white blood cells.
