Interleukin-1 (IL-1), a protein produced by mononuclear phagocytes, helps to initiate the inflammatory response through its action upon a diverse population of cells. Recently this immunomodulator has been detected at sites of traumatized brain. As reported here, recombinant forms of IL-1 injected into the cerebral cortex of adult rats elicit not only astrogliosis but also new blood vessel growth. These responses are typical of brain injury and suggest that IL-1-secreting inflammatory cells may mediate wound healing in the CNS.
白细胞介素-1(IL-1)是一种由单核吞噬细胞产生的蛋白质,它通过作用于多种细胞来帮助启动炎症反应。最近,在脑外伤部位检测到了这种免疫调节剂。如本文所报道,将重组形式的IL-1注入成年大鼠的大脑皮层,不仅会引发星形胶质细胞增生,还会促进新血管生长。这些反应是脑损伤的典型表现,表明分泌IL-1的炎症细胞可能介导中枢神经系统的伤口愈合。
