Integrin α4β1 is required for IL‐1α‐ and Nrf2‐dependent, Cox‐2 induction in fibroblasts, supporting a mechanism that suppresses α‐SMA expression

Growth and repair processes, both normal and pathological, require reciprocal interactions between cells and their microenvironment. Integrins are bidirectional, cell surface receptors that transduce mechanical and chemical signals to and from the extracellular matrix. We recently reported that keratinocyte α3β1 is required for interleukin (IL)‐1α secretion. Importantly, IL‐1α regulates fibroblast Cox‐2 expression and prostaglandin E2 (PGE 2 )...
