WebbThe pathogenesis of idiopathic pulmonary fibrosis (IPF) involves a complex interplay of cell types and signaling pathways. Recurrent alveolar epithelial cell (AEC) injury may occur in the context of predisposing factors (e.g., genetic, environmental, epigenetic, immunologic, and gerontologic), leading to metabolic dysfunction, senescence, aberrant epithelial … Webb29 aug. 2024 · These findings overthrow a long-held view about how epithelial cells themselves kickstart the healing response after injury. The authors believe these results could have implications for several autoimmune conditions, including inflammatory bowel disease and psoriasis, where IL-17a plays a central role.

Over-suppression or over-activation of the immune system can lead to delayed wound healing or pathological inflammation, respectively. Webb1 feb. 2001 · First, epithelial cells adjacent to the injured surface migrate into the wound to cover the denuded area. Those epithelial cells that migrate into the wound defect dedifferentiate, form pseudopodia-like structures, reorganize their cytoskeleton, and redifferentiate after closure of the wound defect. good discord text channels

Webb14 feb. 2013 · To mimic an acute injury, human proximal tubular epithelial cells (TECs) (HKC-8, ATCC, USA) were treated with Cisplatin, a well-known nephrotoxic drug causing DNA crosslinking and TEC apoptosis. A toxic pharmacological injury was preferred to an hypoxic insult. In order to ensure high reproducibility across all experimental groups. WebbA study conducted by Cejkova et al of alkali-induced chemical injury in rabbits, reported that RGTA facilitated the healing of injured corneas by reducing the proteolytic, oxidative, and nitrosative damage. 12 The faster recovery of the epithelium possibly reduces the stimulus for migration of keratocytes at the epithelium/stroma interface, which in turn, …
