Applying TALEN and CRISPR/Cas9 Technique to Knock out the PD1 Gene in Human Primary T Lymphocytes [PDF]
, 2016 过继性细胞免疫治疗(adoptivecellularimmunotherapy)是将患者自体免疫细胞在体外处理，然后筛选并大量扩增具有高度特异性的肿瘤杀伤性免疫效应细胞，再回输到患者体内杀灭肿瘤的一种治疗方法，过继性T细胞治疗是一种很有前景的癌症治疗方法。体内T细胞在进行免疫应答时，T细胞活化需要双重信号的协同作用，分别是抗原呈递信号和协同刺激信号。协同刺激分子通过为淋巴细胞提供正性或负性的调控信号参与机体的免疫调控。肿瘤细胞会利用体内免疫调节过程，表达或分泌的一些分子，对T细胞进行负向调控 ...

The effects of miR-30c-1-3p regulating group ⅡA secretory phospholipase A2（sPLA2-ⅡA）expression on the pathogenic mechanism of atherosclerosis [PDF]
, 2015 动脉粥样硬化（Atherosclerosis，AS）是急性冠脉综合症、脑卒中等众多心脑血管疾病共同的病理基础。sPLA2-ⅡA在动脉粥样硬化病变处含量明显增多、活性显著增强，同时伴随中性粒细胞的增多。sPLA2-ⅡA以酶的催化水解作用和作为致炎因子的促炎症反应双重生物学作用参与AS发生发展的各个阶段。 MicroRNA（miRNA）是近年发现广泛存在于真核细胞中的高度保守的、非编码单链小分子RNA，具有最广泛的基因调节功能，参与机体多种生理、病理过程的调控。 我们运用miRNA靶基因预测软件发现miR ...
