巨噬细胞是体内广泛存在的具有强大吞噬功能的细胞,其形态多样,随功能状态的改变而改变,功能活跃,常伸出较长的伪足;核小,卵圆形或肾形,着色深,核仁不明显,胞质丰富,呈嗜酸性,含空泡和异物颗粒;其主要功能是吞噬和清除异物及衰老伤亡的细胞,分泌多种炎性物质以及参与机体的生理过程。巨噬细胞通过自噬与溶酶体结合,消除、降解受损、变性、衰老和失去功能的细胞、细胞器以及变性蛋白质与 Macrophages are widely existing in the body with a strong phagocytic function of the cells, its diverse forms, with changes in functional status changes, active, often extended longer pseudopodia; nuclear, oval or kidney-shaped, colored Deep, not obvious nucleolus, rich cytoplasm, eosinophilic, containing vacuoles and foreign particles; its main function is to swallow and remove foreign body and aging cells, secrete a variety of inflammatory substances and participate in the body’s physiological processes. Macrophages bind to lysosomes via autophagy to eliminate, degrade, degenerate, senesce, and inactivate cells, organelles, and denatured proteins
