Cluster of differentiation 36 (CD36) is a transmembrane glycoprotein with the ability to bind to multiple ligands and perform diverse functions. Through the recognition of long-chain fatty acids, proteins containing thrombospondin structural homology repeat domains such as thrombospondin-1, and molecules with molecular structures consistent with danger- or pathogen-associated molecular patterns, CD36 participates in various physiological and pathological processes of the body. CD36 is widely expressed in various cell types, including hepatocytes and KCs in the liver, where it plays a pivotal role in lipid metabolism, inflammation, and oxidative stress. Accumulating evidence suggests that CD36 plays a complex role in the development of nonalcoholic simple fatty liver disease and NASH and contributes to the pathogenesis of inflammatory liver injury, hepatitis B/hepatitis C, liver fibrosis, and liver cancer. This review summarizes the current understanding of the structural properties, expression patterns, and functional mechanisms of CD36 in the context of liver pathophysiology. Furthermore, the potential of CD36 as a therapeutic target for the prevention and treatment of liver diseases is highlighted.
分化簇36(CD36)是一种跨膜糖蛋白,能够结合多种配体并执行多种功能。通过识别长链脂肪酸、含有血小板反应蛋白结构同源重复结构域的蛋白质(如血小板反应蛋白-1)以及分子结构与危险或病原体相关分子模式一致的分子,CD36参与机体的各种生理和病理过程。CD36在多种细胞类型中广泛表达,包括肝脏中的肝细胞和枯否细胞,它在脂质代谢、炎症和氧化应激中起关键作用。越来越多的证据表明,CD36在非酒精性单纯性脂肪肝和非酒精性脂肪性肝炎的发展中起复杂作用,并促进炎症性肝损伤、乙型肝炎/丙型肝炎、肝纤维化和肝癌的发病机制。本文综述了目前对CD36在肝脏病理生理学背景下的结构特性、表达模式和功能机制的认识。此外,还强调了CD36作为肝脏疾病预防和治疗靶点的潜力。
