Breast :乳腺癌的免疫预防疫苗或将问世

2013-11-01 孟秋君-编译 the breast journal

一项来自意大利博洛尼亚大学的最新研究显示,在小鼠实验模型上已成功研发了针对乳腺癌进行免疫预防的有效抑制疫苗。该临床前期结果为人类癌症免疫预防基因表达提供了有效参考,同时预示该疫苗可成功实现人类基因表达,属于肿瘤免疫治疗的阶梯形进步。 肿瘤免疫预防可在健康个体中加强免疫防御,并可有效控制肿瘤发病。在以往的研究中,病毒性肿瘤的预防已在人类肝癌

肿瘤免疫预防可在健康个体中加强免疫防御,并可有效控制肿瘤发病。在以往的研究中,病毒性肿瘤的预防已在人类肝癌与宫颈癌群体水平上得到实现。总的来讲,病毒性疫苗可阻止10%以上人类肿瘤的发病。但是,是否该疫苗同时适用于包括乳腺癌在内的非病毒性肿瘤在以往研究中还处于空白阶段。

已在临床前期模型中获得针对具有乳腺癌发展倾向的 HER-2/neu 转基因鼠使用对抗HER-2/neu P185癌基因蛋白疫苗后的研究结果,且该结果颇具前景。保护性免疫机制主要是基于T细胞因子的帮助,特别是伽玛干扰素和反-p185抗体,由疫苗的有效性得到确认。将那些抑制肿瘤增长的抗肿瘤基因模型,特别是针对HER-2起到良好抑制作用的肿瘤模型,对于抑制肿瘤增长是必不可少的。因此代表了肿瘤免疫预防目标的最佳分类。针对免疫预防疫苗对抗肿瘤进展后续阶段的研究结果发现对抗乳腺癌显著失去药效,然而肿瘤恶性进展被成功抑制。
