The role of antigen-presenting cells in the differential expansion of TH1 and TH2 T cells in murine leishmaniasis was investigated. In general, macrophages preferentially induced gamma interferon and interleukin-2 secretion by syngeneic Leishmania-specific T cells, whereas B cells were more efficient in activating interleukin 4 production. B cells from susceptible BALB/c mice were better in inducing TH2 responses than B cells from resistant C57BL/6 mice, whereas macrophages from C57BL/6 mice were superior to BALB/c macrophages in inducing TH1 responses.
研究了抗原呈递细胞在小鼠利什曼病中TH1和TH2 T细胞差异扩增中的作用。一般来说,巨噬细胞优先诱导同基因利什曼原虫特异性T细胞分泌γ干扰素和白细胞介素-2,而B细胞在激活白细胞介素4产生方面更有效。来自易感BALB/c小鼠的B细胞在诱导TH2反应方面比来自抗性C57BL/6小鼠的B细胞更好,而来自C57BL/6小鼠的巨噬细胞在诱导TH1反应方面优于BALB/c巨噬细胞。
