研究興趣和方向:
課題組研究方向集中在腫瘤免疫逃逸機制,機體免疫系統與腫瘤發(fā)生的關(guān)系以及腫瘤的基因和免疫治療的基礎及應用研究研究特色與成果
1. 腫瘤微環(huán)境與腫瘤形成的關(guān)系及基因疫苗研究。
研究腫瘤微環(huán)境中的免疫細胞,如腫瘤相關(guān)的巨噬細胞(TAMs)與腫瘤細胞的相互作用以及與腫瘤發(fā)生,浸潤和轉移的關(guān)系,從中發(fā)現有效的基因或免疫治療的方法。已建立了一系列以抗腫瘤細胞,抗腫瘤新生血管生長(cháng)以及調節腫瘤微循環(huán)的基因和免疫疫苗,并在疫苗的設計以及佐劑的應用上有大膽的創(chuàng )新。
(1)腫瘤相關(guān)抗原Fra-1/IL-18多功能聯(lián)合基因疫苗應用于預防和治療小鼠乳腺癌和直腸癌的研究。該研究成果2003年獲得美國腫瘤學(xué)會(huì )獎勵(AACR-Inglenook Vineyards Scholar-in-Training Award)。論文發(fā)表在PANS和 Cancer Research 。
(2)腫瘤相關(guān)巨噬細胞為靶細胞的調節腫瘤生長(cháng)微環(huán)境的基因疫苗的研究,構建了以L(fǎng)egumain為靶基因 的DNA疫苗清除浸潤進(jìn)人腫瘤組織中的TAM。重建了腫瘤微環(huán)境,使腫瘤細胞向良性分化,減少了腫瘤細胞的轉移。本研究得到了高度評價(jià),2005年獲得美國癌癥學(xué)會(huì )獎勵(AACR-Glaxo Smith Kline Outstanding Clinical Scholar Awards)。相關(guān)論文發(fā)表在JCI, (2006,并在當期的Highlight中作特別介紹)(Cancer Research和CII) 。
2.腫瘤干細胞與腫瘤微環(huán)境中腫瘤相關(guān)巨噬細胞(TAMs)相互作用的研究。
腫瘤微環(huán)境對腫瘤細胞的作用是腫瘤研究的重要領(lǐng)域,我們首先提出 TAMs可能是腫瘤干細胞的Niche,對腫瘤干細胞功能的維持發(fā)揮支持和調節作用。
(1)在首先發(fā)現TAM對CSC中 EGF-R/STAT3/SOX2高表達信號轉導通路異常調節的基礎上,系統的分析TAMs與腫瘤干細胞相互作用促進(jìn)腫瘤細胞生長(cháng)和轉移的分子基礎。這一發(fā)現對研究腫瘤微環(huán)境與腫瘤干細胞的關(guān)系的基礎及臨床應用研究具有重要的意義, 文章發(fā)表后得到同行積極的反應。 2010年獲得美國癌癥學(xué)會(huì )獎勵AACR Susan G. Komen Scholar in Training Award, 相關(guān)論文發(fā)表在BJC; Stem cell,。
(2)研究發(fā)現TAMs中高表達Fra-1轉錄因子和IL-6/Stat3信號轉導通路,而高表達的Fra-1與激活的 IL-6/Stat3信號轉導通路高度相關(guān)。(Oncogene,2010,引用 34次)進(jìn)一步,我們找到一種microRNA即miR-19a-3p,它是一種在腫瘤相關(guān)巨噬細胞受腫瘤微環(huán)境刺激并向M2型極化過(guò)程中表達受明顯抑制,miR-19a-3p在抑制TAM向M2型極化過(guò)程中起關(guān)鍵性作用,而腫瘤微環(huán)境通過(guò)分泌IL-6來(lái)抑制miR-19a-3p的表達來(lái)促進(jìn)TAM的M2極化,從而促進(jìn)腫瘤的發(fā)展和轉移。這一結論為利用miRNA調控了腫瘤微環(huán)境提供了理論依據。(Oncogene;2013)。
