Leishmaniasis affects approximately 2 million people each year throughout the world. This high incidence is due in part to the lack of an efficacious vaccine. We present evidence that the recombinant leishmanial antigens LmSTI1 and TSA, which we identified and characterized previously, induce excellent protection in both murine and nonhuman primate (rhesus monkey) models of human cutaneous leishmaniasis. The remarkable protection induced by LmSTI1 and TSA in an animal model that is evolutionarily close to humans qualifies this antigen combination as a promising candidate subunit vaccine against human leishmaniasis.
利什曼病每年在全球影响约200万人。这种高发病率部分归因于缺乏有效的疫苗。我们提供的证据表明,我们之前鉴定和表征的重组利什曼原虫抗原LmSTI1和TSA,在人类皮肤利什曼病的小鼠和非人类灵长类动物(恒河猴)模型中均能诱导出极佳的保护作用。LmSTI1和TSA在与人类进化关系密切的动物模型中诱导出的显著保护作用,使这种抗原组合成为一种有前景的抗人类利什曼病亚单位疫苗候选物。
