Tamm-Horsfall蛋白在肾小管间质性肾炎免疫发病机理中的作用
THE ROLE OF TAMM-HORSFALL PROTEIN IN THE IMMUNOPATHOGENESIS OF TUBULOINTERSTITIAL NEPHRITLS
【摘要】 作者从单核、淋巴因子的角度探讨了Tamm-Horsfall蛋白(THP)与免疫系统的关系,以及THP通过自身免疫反应诱发肾小管间质性肾炎(TIN)的机制。系列研究的结果提示,在生理状态下。THP可能参于了肾脏对某些细胞因子,诸如白细胞介素1、白细胞介素2和肿瘤坏死因子的清除与代谢。当某些病理状态致THP直接进入肾间质时,则可能通过激发细胞免疫反应导致TIN。单核/巨噬细胞及其分泌的某些单核因子是介导这类TIN组织炎症和纤维化的关键因素。这一结论不仅有助于进一步阐明THP的病理生理作用。同时也可能给某些TIN的治疗以新的启示。
【Abstract】 he relationship between Tamm-Horsfall protein (THP ) and cytokines and the immuno- logical mechanism was studied , by which THP triggers tubulointerstitial nephritis (TIN ). The results showed that THP might play physiologically an important role in the regulation of intrarenal bioactivity of many potent cytokines , including IL-1 , IL-2 and TNF. In some disease states , however , THP could deposit in the extra-tubular interstitium through leak- age of urine from rupture of obstructed or damaged tubules , and might be able to activate cell-mediated immunity to induce TIN. Monocytes/macrophages and monokines produced by these cells played a key role in the tissue injury in this type of TIN and probably contributed to tubulointerstitial fibrosis. Besides their significance in the understanding of the patho- physiologic effects of THP , the results may also provide a new hint for the treatment of some types of TIN.
