Toll-like receptor 4 (TLR4) plays an important role in the pattern recognition of Mycobacterium tuberculosis, and polymorphisms in the TLR4 gene influence the function of the receptor. We therefore investigated in a cohort of HIV-infected Tanzanian patients whether the Asp299Gly TLR4 polymorphism is associated with the development of active tuberculosis. We found a greater risk of developing active tuberculosis as well as a reduction in CD4 T-cell counts in patients with the Asp299Gly TLR4 polymorphism.
Toll样受体4（TLR4）在结核分枝杆菌的模式识别中起重要作用，TLR4基因的多态性会影响该受体的功能。因此，我们在一群感染了HIV的坦桑尼亚患者中进行了研究，以探讨TLR4基因Asp299Gly多态性是否与活动性结核病的发生有关。我们发现，具有TLR4基因Asp299Gly多态性的患者发生活动性结核病的风险更高，且CD4 T细胞计数减少。
