Ablation of integrin-mediated cell–collagen communication alleviates fibrosis

Activation of fibroblasts is a hallmark of fibrotic processes. Besides cytokines and growth factors, fibroblasts are regulated by the extracellular matrix environment through receptors such as integrins, which transduce biochemical and mechanical signals enabling cells to mount appropriate responses according to biological demands. The aim of this work was to investigate the in vivo role of collagen–fibroblast interactions for regulating fibroblast functions and fibrosis.
