Fibrosis is a common and intractable condition associated with various pathologies. It is characterized by accumulation of an excessive amount of extracellular matrix molecules that primarily include collagen type I. IL-6 is a profibrotic cytokine that is elevated in the prototypic fibrotic autoimmune condition systemic sclerosis and is known to induce collagen I expression, but the mechanism(s) behind this induction are currently unknown. Using healthy dermal fibroblasts in vitro, we analyzed… CONTINUE READING
