Cachectin/TNF (tumor necrosis factor), an endotoxin-induced murine macrophage hormone implicated in the pathogenesis of cachexia and shock, has been found capable of stimulating collagenase and prostaglandin E2 (PGE2) production by isolated human synovial cells and dermal fibroblasts. This bioactivity associated with cachectin is comparable to that observed with the monokine interleukin 1 (IL-1), previously suggested as the major mediator of proteolysis. The ability of cachectin/TNF to stimulate collagenase and PGE2 production suggests that it may play a role in tissue destruction and remodelling, as these processes occur in inflammatory diseases.
恶病质素/肿瘤坏死因子(TNF)是一种由内毒素诱导产生的鼠巨噬细胞激素,与恶病质和休克的发病机制有关,现已发现它能够刺激分离出的人滑膜细胞和皮肤成纤维细胞产生胶原酶和前列腺素E2(PGE2)。与恶病质素相关的这种生物活性与之前被认为是蛋白水解主要介质的单核因子白细胞介素1(IL-1)所观察到的生物活性相当。恶病质素/TNF刺激胶原酶和PGE2产生的能力表明,在炎症性疾病中出现的组织破坏和重塑过程中,它可能发挥作用。
