Cryptococcus neoformans capsular glucuronoxylomannan (GXM) is shed during cryptococcosis and taken up by macrophages. The roles of the putative GXM receptors CD14, CD18, Toll-like receptor 2 (TLR2), and TLR4 in GXM clearance from serum and deposition in the liver and spleen in receptor-deficient mice were studied. While alterations in the kinetics of GXM redistribution were seen in the mutant mice, none of the receptors was absolutely required for serum clearance or hepatosplenic accumulation.
新型隐球菌荚膜葡糖醛酸木聚糖甘露聚糖(GXM)在隐球菌病期间脱落并被巨噬细胞摄取。研究了假定的GXM受体CD14、CD18、Toll样受体2(TLR2)和TLR4在受体缺陷小鼠中从血清清除GXM以及在肝脏和脾脏中沉积的作用。虽然在突变小鼠中观察到GXM重新分布动力学的改变,但血清清除或肝脾积累并非绝对需要任何一种受体。
