摘要: TFEB作为一种新型转录因子,可由mTOR、细胞应激等自噬调节因子激活,介导自噬、溶酶体相关基因以及过氧化物酶体增殖物激活受体α(PPAR α)、过氧化物酶体增殖活化受体γ共激活因子-1α(PGC-1α)的表达,促进脂质外排、抑制炎性因子释放。TFEB调节脂质代谢可作为一种新机制,起到抑制动脉粥样硬化进展、稳定斑块的作用。

Abstract: TFEB could induced by autophagic regulatory factors, such as mTOR and cellular stresses. TFEB could media the translation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PPAR α), peroxisome proliferator-activated receptor γ coactivator 1 α(PGC-1α) and autophagy, lysosomal synthesis related genes, then regulat lipid metabolism and the release inflammatory cytokine. AS a novel Mechanism, TFEB could regulate Lipid metabolism in order to restrain the progression of atherosclerosis and promote to plaque stabilization.

Key words: TFEB , atherosclerosis, autophagy, PPAR α, PGC-1α
