结核病时细胞反应活性的变化与迟发型超敏反应调节细胞的功能有关。在这类细胞中有表面带抗原—抗体复合物的淋巴细胞,它能抑制迟发型超敏反应。体内体外试验均证实这种迟发型超敏反应抑制细胞的活性受C_(1q)调节。C_(1q)由于能清除其表面IC,所以
The changes of cell reactivity in tuberculosis are related to the function of delayed-type hypersensitivity regulating cells. In these cells there are surface lymphocytes with antigen-antibody complexes that inhibit the delayed type hypersensitivity. In vitro and in vivo tests confirm that this delayed type hypersensitivity inhibits cell activity regulated by C_ (1q). C_ (1q) can clear its surface IC, so
