Lipopolysaccharide (LPS)-responsive and LPS-defective strains of C3H mice did not differ in the capacity to make an antibody response to type III pneumococcal polysaccharide or in the degree of thymus-derived suppressor cell (Ts) activity generated following exposure to type III pneumococcal polysaccharide. However, treatment with monophosphoryl lipid A (MPL) abolished the expression of Ts function in LPS-responsive but not LPS-defective mice. Since this effect was elicited by different preparations of MPL, it appears to be a general property of MPL mediated by direct action of MPL on activated Ts.
C3H小鼠的脂多糖(LPS)反应性和LPS缺陷型品系在对III型肺炎球菌多糖产生抗体反应的能力上,或在暴露于III型肺炎球菌多糖后产生的胸腺来源抑制性细胞(Ts)活性程度上并无差异。然而,单磷酰脂质A(MPL)处理消除了LPS反应性小鼠而非LPS缺陷型小鼠中Ts功能的表达。由于不同的MPL制剂均可引发这种效应,所以这似乎是MPL通过直接作用于活化的Ts所介导的一种普遍特性。
