The process of dead cell clearance by phagocytic cells, called efferocytosis, prevents inflammatory cell necrosis and promotes resolution and repair. Defective efferocytosis contributes to the progression of numerous diseases in which cell death is prominent, including liver disease. Many gaps remain in our understanding of how hepatic macrophages carry out efferocytosis and how this process goes awry in various types of liver diseases. Thus far, studies have suggested that, upon liver injury, liver-resident Kupffer cells and infiltrating monocyte-derived macrophages clear dead cells, limit inflammation, and, through macrophage reprogramming, repair liver damage. However, in unusual settings, efferocytosis can promote liver disease. In this review, we will focus on efferocytosis in various types of acute and chronic liver diseases, including metabolic dysfunction-associated steatohepatitis. Understanding the mechanisms and consequences of efferocytosis by hepatic macrophages has the potential to shed new light on liver disease pathophysiology and to guide new treatment strategies to prevent disease progression.
吞噬细胞清除死亡细胞的过程称为胞葬作用,它可防止炎症细胞坏死,并促进炎症消退和组织修复。胞葬作用缺陷会促使众多以细胞死亡为突出特征的疾病进展,包括肝脏疾病。在我们对肝巨噬细胞如何进行胞葬作用以及该过程在各种类型肝病中如何出错的理解方面,仍存在许多空白。到目前为止,研究表明,在肝损伤时,肝脏常驻库普弗细胞和浸润的单核细胞衍生巨噬细胞清除死亡细胞,限制炎症,并通过巨噬细胞重编程修复肝损伤。然而,在特殊情况下,胞葬作用可促进肝病发展。在本综述中,我们将聚焦于各种类型的急性和慢性肝病中的胞葬作用,包括代谢功能障碍相关脂肪性肝炎。了解肝巨噬细胞胞葬作用的机制和后果,有可能为肝病病理生理学提供新的见解,并指导预防疾病进展的新治疗策略。
