During development of adjuvant arthritis (AA) in the rat, anterior pituitary interleukin-6 (IL-6) mRNA expression was increased. Following adrenalectomy and AA there was a further increase in the accumulation of pituitary IL-6 transcript. Corticosterone (B) replacement in adrenalectomized (ADX) animals resulted in a dose-dependent reduction in pituitary IL-6 mRNA accumulation, while in ADX plus AA animals these effects of B were less marked. Cyclosporine A (CsA) markedly reduced the AA-induced increase in IL-6 mRNA. These data are consistent with an immunologically-mediated activation of pituitary IL-6 mRNA in AA, which may contribute to the increased activity of the pituitary-adrenal axis seen in this condition.
在大鼠佐剂性关节炎(AA)的发展过程中,垂体前叶白细胞介素-6(IL-6)mRNA表达增加。肾上腺切除术后发生AA时,垂体IL-6转录物的积累进一步增加。给肾上腺切除(ADX)的动物补充皮质酮(B)导致垂体IL-6 mRNA积累呈剂量依赖性减少,而在ADX加AA的动物中,B的这些作用不太明显。环孢素A(CsA)显著降低了AA诱导的IL-6 mRNA增加。这些数据与AA中垂体IL-6 mRNA的免疫介导激活一致,这可能导致在这种情况下观察到的垂体-肾上腺轴活性增加。
