Autophagy is a critical intracellular pathway which maintains cellular function by lysosomal degradation of damaged proteins and organelles besides elimination of invading pathogens. Its primary function is to prevent cell death. Autophagy has diverse physiological functions namely; starvation adaptation, prevention of tumorigenesis, energy homeostasis, intracellular quality control and degradation of abnormal intracellular protein aggregates. Understanding the molecular mechanisms of autophagy has given key insights into the pathogenesis of various diseases like Non Alcoholic Steato-Hepatitis, Hepatitis B and C infections, Alpha-1 antitrypsin deficiency and hepatocellular carcinoma. Pharmacological modulation of autophagy may have a therapeutic potential in management of these liver diseases.
自噬是一种关键的细胞内途径,它通过溶酶体降解受损蛋白质和细胞器来维持细胞功能,此外还能清除入侵的病原体。其主要功能是防止细胞死亡。自噬具有多种生理功能,即饥饿适应、预防肿瘤发生、能量稳态、细胞内质量控制以及异常细胞内蛋白质聚集体的降解。对自噬分子机制的理解为深入了解各种疾病的发病机制提供了关键见解,如非酒精性脂肪性肝炎、乙型和丙型肝炎感染、α-1抗胰蛋白酶缺乏症以及肝细胞癌。自噬的药理调节在这些肝脏疾病的治疗中可能具有治疗潜力。
