Abstract

Many chronic diseases are marked by fibrosis, which is defined by an abundance of activated fibroblasts and excessive deposition of extracellular matrix, resulting in loss of normal function of the affected organs. The initiation and progression of fibrosis are elaborated by pro-fibrotic cytokines, the most critical of which is transforming growth factor-β1 (TGF-β1). This review focuses on the fibrogenic roles of increased TGF-β activities and underlying signaling mechanisms in the activated fibroblast population and other cell types that contribute to progression of fibrosis. Insight into these roles and mechanisms of TGF-β as a universal driver of fibrosis has stimulated the development of therapeutic interventions to attenuate fibrosis progression, based on interference with TGF-β signaling. Their promise in preclinical and clinical settings will be discussed. © 2021 The Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.

摘要

许多慢性疾病的特征是纤维化,其定义为大量激活的成纤维细胞和细胞外基质的过度沉积,导致受影响器官的正常功能丧失。纤维化的启动和进展由促纤维化细胞因子详细阐述,其中最重要的是转化生长因子-β1(TGF-β1)。本综述重点介绍了 TGF-β活性增加和潜在信号机制在激活的成纤维细胞群体和其他有助于纤维化进展的细胞类型中的纤维生成作用。深入了解 TGF-β作为纤维化的普遍驱动因素的这些作用和机制,激发了基于干扰 TGF-β信号的治疗干预措施的发展,以减轻纤维化进展。将讨论它们在临床前和临床环境中的前景。©2021 大不列颠及爱尔兰病理学学会。由 John Wiley & Sons, Ltd 出版。
