摘要
创面修复过程中的炎症反应对创面愈合既有促进作用也有抑制作用。适度的炎症反应有助于免疫防御的启动和各种生长因子的产生,过度的炎症反应则会导致瘢痕组织过度增生及机体的组织损伤。树突状表皮T淋巴细胞(DETC)起源于小鼠的胸腺后定殖于表皮并特异性地表达Vγ3Vδ1 T淋巴细胞受体(TCR)。其在创面愈合过程中不仅可以通过释放各种趋化因子和促炎因子扩大炎症反应,还有可能通过抗炎介质缓解机体的过度炎症反应从而促进创面愈合。
Inflammatory response can not only promote but also inhibit wound healing.Moderate inflammatory response is beneficial to the initiation of an immune response and the production of various growth factors.However,excessive inflammatory response will lead to hyperplastic scars and tissue injury in the body.Dendritic epidermal T lymphocytes(DETCs),which specifically express the Vγ3δ1TCR,are originated from the thymus of mice and then colonized on the epidermis.In the process of wound healing,DETCs can not only exacerbate the inflammatory response by releasing various chemokines and pro-inflammatory factors,but also alleviate the excessive inflammatory response of the body through anti-inflammatory mediators to promote wound healing.
