Lymphocytes play an important part in the development and progression of a number of autoimmune and inflammatory disorders, which are characterized by the presence of activated T cells and cytokines at the site of tissue injury and in the circulation. There has been considerable interest in using dietary polyunsaturated fatty acids (PUFA), particularly the n-3 PUFA found in fish oils, in the therapy of these conditions; such therapies aim, primarily, to suppress T-lymphocyte activity. While several studies have investigated the effects of fatty acids on the production of monocyte- and macrophage-derived cytokines, few have investigated their effects on the production of T cell-derived cytokines. Each of these studies have been restricted to IL-2 and have produced results which are not entirely clear. Moreover, there have been no studies to investigate the effects of dietary lipids other than fish oils on IL-2 production or the effects of dietary lipids on lymphokines other than IL-2. To investigate the effects of dietary lipid manipulation on the production of IL-2, IL-4, IL-10 and IFN-gamma by lymphocytes, mice were fed for 8 weeks on a low fat (LF) diet or one of 4 high fat diets, which contained 20% (by weight) hydrogenated coconut oil (HCO), olive oil (OO), safflower oil (SO) or menhaden oil (MO). Culture medium of lymphocytes from mice fed the OO or SO diets contained significantly more IL-2 than that of lymphocytes from mice fed the LF or HCO diets.(ABSTRACT TRUNCATED AT 250 WORDS).
