英文摘要	recent studies have shown that polyunsaturated fatty acids (pufa) regulated the functions of membrane receptors in t cells and suppressed t cell-mediated immune responses. but the molecular mechanisms of immune regulation are not yet elucidated. lipid rafts are plasma membrane microdomains, in which many receptors localized. the purpose of this study was to investigate the effect of dha on il-2r signaling pathway in lipid rafts. we isolated lipid rafts by discontinuous sucrose density gradient ultracentrifugation, and found that dha could change the composition of lipid rafts and alter the distribution of key molecules of il-2r signaling pathway, which transferred from lipid rafts to detergent-soluble membrane fractions. these results revealed that dha treatment increased the proportion of polyunsaturated fatty acids especially n-3 polyunsaturated fatty acids in lipid rafts and changed the lipid environment of membrane microdomains in t cells. compared with controls, dha changed the localization of il-2r, stat5a and stat5b in lipid rafts and suppressed the expression of jak1, jak3 and tyrosine phosphotyrosine in soluble membrane fractions. summarily, this study concluded the effects of dha on il-2r signaling pathway in lipid rafts and explained the regulation of pufas in t cell-mediated immune responses.
