Prostaglandins and Expression of Lymphocyte Cytotoxicity
- 27 Downloads
The suggestion that prostaglandins may play an important role in immune response/tumor cell interactions is based upon several observations. First, a variety of prostaglandins are produced both by cells that are themselves active in the expression and regulation of immune response activity (1–4) as well as by a number of tumor targets (5,6). Second, the production of prostaglandins has been found to increase as a result of direct contact between effector lymphocytes and tumor targets (7). Third, prostaglandins at levels produced during these interactions have been shown to influence the ultimate expression in vitro of lymphocyte and macrophage cytotoxicity against tumor targets (8–12).
