脂类物质作为细胞及细胞膜的一个重要组成部分,对于生物体有着重要影响。近年来,有关n-3多不饱和脂肪酸(n-3 PUFA)、溶血卵磷脂和鞘氨醇-1-磷酸等物质对T细胞影响的研究取得了重要进展,发现了n-3 PUFA具有免疫抑制的作用,而鞘氨醇-1-磷酸和溶血卵磷脂分别对T细胞因子的分泌、免疫稳态和T淋巴细胞进出循环系统有着重要影响。在此基础上,一些相关的生物活性物质被鉴定,并且有望开发成为有效的治疗药物。
As one of the important components of cell and cell membrane, lipids play important roles in cell functions. Among these, scientists have made progresses in elucidating the effects of n-3 poly unsaturated fatty acids (n-3 PUFA), lysophosphatidylcholine and sphingosine 1-phosphate on T cell. It has been discovered that n-3 PUFA has an effect of immune suppression, while, lysophosphatidylcholine and sphingosine 1-phosphate can impose important effects respectively on the secretion of cytokines, immune homeostasis and T lymphocyte egress into circulation system. Based on those, several kinds of bioactive substances have been identified, which have potentials of developing into effective therapeutic drugs.
