High in vitro lymphoproliferative responses were induced in humans and dogs by a recombinant Leishmania (Leishmania) chagasi cysteine proteinase, with secretion of IFN-gamma in asymptomatic subjects or of IFN-gamma, interleukin 4 (IL-4), and IL-10 in oligosymptomatic subjects. In contrast, responses of symptomatic patients and dogs were lower, with production of IL-4 and IL-10.
重组恰加斯利什曼原虫半胱氨酸蛋白酶在人和犬中诱导出了较高的体外淋巴细胞增殖反应,无症状受试者分泌γ干扰素,而少症状受试者分泌γ干扰素、白细胞介素4(IL-4)和白细胞介素10。相比之下,有症状患者和犬的反应较低,产生IL-4和IL-10。
