Cellular adhesive connections directed by the extracellular matrix (ECM) and maintenance of cellular homeostasis by autophagy are seemingly disparate functions that are molecularly intertwined, each regulating the other. This is an emerging field in the brain where the interplay between adhesion and autophagy functions at the intersection of neuroprotection and neurodegeneration. The ECM and adhesion proteins regulate autophagic responses to direct protein clearance and guide regenerative programs that go awry in brain disorders. Concomitantly, autophagic flux acts to regulate adhesion dynamics to mediate neurite outgrowth and synaptic plasticity with functional disruption contributed by neurodegenerative disease. This review highlights the cooperative exchange between cellular adhesion and autophagy in the brain during health and disease. As the mechanistic alliance between adhesion and autophagy has been leveraged therapeutically for metastatic disease, understanding overlapping molecular functions that direct the interplay between adhesion and autophagy might uncover therapeutic strategies to correct or compensate for neurodegeneration.
由细胞外基质(ECM)引导的细胞黏附连接以及通过自噬维持细胞内稳态,这两种功能看似不同,但在分子层面相互交织,彼此相互调节。这是大脑中一个新兴的领域,其中黏附与自噬功能之间的相互作用发生在神经保护和神经退行性变的交叉点。ECM和黏附蛋白调节自噬反应以直接清除蛋白质,并指导在脑部疾病中出错的再生程序。与此同时,自噬流作用于调节黏附动力学,以介导神经突生长和突触可塑性,而神经退行性疾病会导致功能破坏。本综述强调了健康和疾病状态下大脑中细胞黏附与自噬之间的协同作用。由于黏附与自噬之间的机制联盟已被用于转移性疾病的治疗,了解指导黏附与自噬相互作用的重叠分子功能可能会揭示纠正或补偿神经退行性变的治疗策略。
