TNF-like weak inducer of apoptosis (TWEAK), a TNF superfamily ligand, and its bona fide receptor, the TNF receptor superfamily member fibroblast growth factor-inducible 14 (Fn14), represent a pivotal axis for shaping both physiological and pathological tissue responses to acute or chronic injury and disease. In recent years significant advances have been made in delineating the prominent role of TWEAK-Fn14 dyad in regulating skeletal muscle mass and metabolism. Also emerging from the broad study of tissue injury in skeletal muscle and other organs is the role of the TWEAK-Fn14 pathway in promoting fibrosis. This review article highlights recent advancements toward understanding how the TWEAK-Fn14 pathway regulates the response to various skeletal muscle insults and, more broadly, engages multiple mechanisms to drive tissue fibrosis.
肿瘤坏死因子样弱凋亡诱导因子(TWEAK)是肿瘤坏死因子超家族配体,其真正的受体是肿瘤坏死因子受体超家族成员成纤维细胞生长因子诱导 14(Fn14),它们是调节组织对急性或慢性损伤和疾病的生理和病理反应的关键轴。近年来,在阐明 TWEAK-Fn14 二聚体在调节骨骼肌质量和代谢中的突出作用方面取得了重大进展。从对骨骼肌和其他器官组织损伤的广泛研究中也出现了 TWEAK-Fn14 途径在促进纤维化中的作用。本文综述了近年来在理解 TWEAK-Fn14 途径如何调节各种骨骼肌损伤反应方面的进展,更广泛地说,该途径通过多种机制参与驱动组织纤维化。
