疟疾是一个重大的全球卫生问题,在这个问题上,我们仍然不能理解许多人。
保护性免疫是机体免疫系统反应的重要特征。自然杀伤细胞(NK)分泌的细胞会产生免疫反应。
炎症和细胞因子是在感染的早期阶段产生的,但在其他疾病中也没有表现出来。
病毒感染模型旨在限制T细胞和B细胞的反应。我们最近证实,T细胞和B细胞的反应
产生的IL-10可在实验性脑型疟疾防治期间限制CD8+T细胞活性。
从而将小鼠从致命的CD8+T细胞介导的免疫病理学中解救出来,并使用新的方法。
由小鼠产生的菌株,我们将通过视觉观察NK1细胞的位置和细胞间的相互作用。
在人类大脑发育过程中,脑组织建立了NK细胞衍生的IL-10的主要细胞免疫靶标。
疾病。我们的新研究也将无法确定人类不同的NK细胞亚群是否更多。
如果这些细胞与预防疟疾的机制相关,那么高效的方法就是产生IL-10、IL-10和IL-10。
症状出现在人类身上。最后,我们将继续调查NK细胞衍生的IL-10对人类健康的影响。
CD8+T细胞的新的发育过程和功能变化。我们的目标是很难理解。
NK细胞的调节功能如IL-10的产生如何减少免疫病理反应。
有症状的病毒感染,并形成新的发展中的T细胞免疫反应。这项工作建议。
将不会确定在全球免疫应答过程中NK细胞衍生的IL-10的主要后果。
研究疟疾防治工作,揭示如何更好地利用自然杀伤细胞的监管功能,从而改善疟疾的状况。
在一些面临严重传染病风险的人群中,免疫力低下。
英文摘要
Project Summary/Abstract
Malaria is a significant global health problem in which we still fail to understand many
protective features of the immune response. Natural killer (NK) cells produce
inflammatory cytokines during the early stages of infection, yet have also been shown in
viral models to limit T cell and B cell responses. We recently demonstrated that NK cell-
produced IL-10 can limit CD8+ T cell activity during experimental cerebral malaria and
thereby rescue mice from fatal, CD8+ T cell-mediated immunopathology. Using newly
generated mouse strains, we will visual the location and cellular interactions of NK cells
in the brain and establish the cellular targets of NK cell-derived IL-10 during cerebral
disease. Our studies will also determine if distinct human NK cell subsets are more
efficient at producing IL-10, and if these cells correlate with protection from malaria
symptoms in humans. Finally, we will investigate the impact of NK cell-derived IL-10 on
the development and function of memory CD8+ T cells. Our objective is to understand
how NK cell regulatory functions like IL-10 production decrease immunopathology and
symptomatic infection, and shape the developing T cell response. The proposed work
will determine the consequences of NK cell-derived IL-10 during the immune response
to malaria and reveal ways to exploit regulatory NK cell function, thereby improving
immunity in populations at risk for severe disease.
