T细胞反应是获得性免疫反应的中心,在机体抗病原微生物感染和肿瘤的免疫应答中起关键作用,还参与感染和自身免疫疾病等各种疾病的免疫病理过程。T细胞受到抗原刺激被激活后,在不同的微环境条件下会分化成不同的功能亚群,发挥不同的效应功能。免疫应答是由重多免疫细胞和分子参与的复杂过程,受到机体非常复杂而精细的调控,从而保证免疫反应的适度发生,即抵抗了病原微生物的侵染和肿瘤的发生,又不至于引起机体免疫病理损伤而引发各种疾病。调控T细胞反应,已广泛用于各种免疫相关疾病的治疗和治疗研究,其中通过抗体阻断T细胞反应负调控信号,被认为是肿瘤治疗的方向。目前课题组主要研究方向有以下几方面:
1. 记忆性T细胞分化的调控机制:<免疫记忆是获得性免疫应答的显著特征,对疫苗预防接种、机体抵抗病原微生物的再次感染、抗肿瘤和防止肿瘤复发起着重要作用。但相对于CD4+T细胞不同功能亚群的分化,记忆性T细胞分化的调控机制研究严重滞后,目前所知甚少。我们建立了体外和体内的记忆性T细胞分化体系,利用最新的定量蛋白组学技术,同时结合分子和细胞生物学方法及小鼠模型,研究记忆性T细胞分化的分子机制。
2. 树突状细胞(DCs)的分化机制:DCs是先天免疫的主要反应细胞,也是获得性免疫的发动者,是连接先天和获得性免疫的桥梁。DCs分为多个功能和表型不同的亚群,在体内发挥各自独特的重要免疫调控功能,但目前对不同DCs细胞分化的调控机制所知甚少。我们发现去SUMO化酶(SENP-1)基因敲除小鼠的DCs在不同的分化阶段具有独特的分化缺陷,目前主要是利用该小鼠研究DCs的分化机制。
3. 抗肿瘤免疫机制及肿瘤免疫治疗:随着抗抑制性共刺激分子CTLA-4抗体被美国FDA批准用于黑色素瘤临床治疗,以及以PD-1抑制信号为靶点的肿瘤免疫治疗临床试验取得惊人疗效,肿瘤免疫治疗被认为是肿瘤治疗新的希望,受到广泛关注。我们的研究方向是肿瘤微环境(肿瘤组织和肿瘤引流淋巴结)的抗肿瘤免疫机制和肿瘤免疫耐受机制,重点研究抑制性共刺激信号和肿瘤相关巨噬细胞(TAM)对机体抗肿瘤免疫的抑制作用,及其对肿瘤常规治疗的影响,发展以这些肿瘤免疫耐受机制为靶点的肿瘤免疫治疗新途径。
