承担项目情况
艾滋病的人源化小鼠模型：艾滋病是由人免疫缺陷病毒（HIV）感染所引起的以CD4辅助性T细胞减少为特征的传染病。没有合适的动物模型是制约艾滋病研究的重要因素之一。我们利用严重免疫缺陷的小鼠（Rag2-/-gammaC-/-），通过移植人的造血干细胞，构建了免疫系统人源化的小鼠模型。移植细胞在小鼠体内发育成为人的各种免疫细胞，并能够在抗原的刺激下产生功能性的免疫应答。HIV能够感染人源化的小鼠并杀伤CD4＋ T 淋巴细胞。利用这一模型，我们初步开展了HIV致病机理、变异规律以及抗病毒药物的研究。在此基础之上，我们将进一步研究HIV感染的致病机理，主要是浆样树突状细胞（pDC）在HIV感染中的作用（见下面pDC的相关介绍）。
浆样树突状细胞及其在病毒感染中的作用：浆样树突状细胞（pDC）高表达Toll样受体7（TLR7）和TLR9，在病毒或其他刺激下能够产生大量Ⅰ型干扰素，并成熟为抗原提成细胞（APC）。它产生Ⅰ型干扰素的能力是其它细胞的100-1000倍，因此又被称为干扰素产生细胞。近年来的研究表明，虽然pDC在人的外周血中的比例仅为0.2-0.5%，但它在抗感染免疫，自身免疫病和肿瘤免疫中都起着非常重要的作用。在病毒感染中，它通过TLR7和TLR9分别识别病毒的RNA和DNA，释放大量干扰素和炎性因子，激活NK细胞和髓样树突状细胞（mDC）等其他天然免疫细胞；成熟为APC之后又能活化T细胞，启动适应性免疫。关于pDC，我们对以下两方面感兴趣：1. pDC产生干扰素和炎性因子的分子机制；2. 在HIV、HBV等病毒感染中，pDC在免疫逃逸和免疫病理中的作用。
