阅读下面两个材料并回答问题:
【材料一】2011年10月3日,诺贝尔奖委员会宣布,美国科学家布鲁斯·巴特勒、卢森堡科学家朱尔斯·霍夫曼和加拿大科学家拉尔夫·斯坦曼获得2011年诺贝尔医学生理学奖。在长期进化过程中人体具备两种免疫机能:一是“固有免疫”,二是“获得性免疫”。布鲁斯·巴特勒、朱尔斯·霍夫曼的获奖领域在前者;而拉尔夫·斯坦曼的工作主要在后者。
布鲁斯·巴特勒、朱尔斯·霍夫曼发现了由“Toll”基因编码的关键受体蛋白,该受体蛋白能识别病原微生物,并激活“固有免疫”,打开免疫反应的第一步;拉尔夫·斯坦曼发现的树突状细胞在免疫应答中作用,树突状细胞在体内游弋,发现并摄取病原体的特异性抗原,并报告给T淋巴细胞,T细胞将调动其他免疫细胞发生级联反应,最终消灭病原体。
(1)材料中所描述的“固有免疫”就是_____________________免疫,这种免疫对所有的病原体都有防御作用。(1分)
(2)下列有关“Toll”基因的叙述正确的是:_____________(单选)(1分)
A.Toll基因只存在于免疫细胞中
B.Toll基因编码受体蛋白,体现基因对性状的直接控制
C.Toll基因编码的受体蛋白能识别病原微生物,体现了免疫细胞的特异性识别
D.效应T细胞能与靶细胞密切接触就是该受体功能体现
(3)下列有关树突状细胞的叙述正确的是:_____________________(不定项)
A.树突状细胞在免疫中发挥作用,说明神经系统与免疫系统功能密切相关
B.在细胞免疫和体液免疫中树突状细胞所起的作用没有明显差别
C.树突状细胞能够处理和呈递病原体的抗原特异性
D.树突状细胞可触发T细胞发生免疫反应
E.树突状细胞可能是一种吞噬细胞
【材料二】(根据南方周末《乔布斯的错误与诺奖得主的试验》整理)就在瑞典卡罗琳医学院宣布本年度诺贝尔医学奖的前3天,斯坦曼因胰腺癌不幸离世,他没能亲耳听到自己获奖的喜讯,令人惋惜。就在他离世死后的第6天“改变世界”的IT精英乔布斯也因胰腺癌英年早逝。
两人所患的胰腺癌都是死亡率极高的恶性肿瘤。乔布斯患的是“胰腺内分泌型肿瘤”,该病症病情发展缓慢,能存活数年的患者不在少数。但这位著名的素食主义者曾一度拒绝手术治疗,导致肿瘤细胞转移,病情迅速恶化。
而斯坦曼所患的病症为“胰腺外分泌型肿瘤”,该病患者的存活期往往只有数月。斯坦曼在2007年确诊胰腺癌后,就积极尝试基于树突状细胞的治疗性疫苗(DC疫苗)。借助这种“细胞免疫疗法”,他的生命从预期的数月延长至4年。
(4)乔布斯癌变的细胞可能是_____________细胞,该细胞的分泌物与_________________。系统消灭癌细胞的过程是_____________(填一种特异性免疫)发挥作用。
(5)斯坦曼所注射的DC疫苗是由其体内的树突状细胞和肿瘤细胞中提取的一种短肽(即治疗性疫苗),该短肽在免疫中作为_____________引起人体发生免疫反应。除树突状细胞外,斯坦曼体能够特异性识别这种短肽的细胞还有(至少写出3种)______________________________________。
(6)有人认为DC疫苗对防治癌症有一定的疗效,原因是:通过免疫反应斯坦曼体内的免疫系统产生抗体,抗体与该短肽特异性结合,使短肽失效。你认为这个解释对吗,____________,请说出你的理由:_________________________。(共2分)
(7)斯坦曼生前尝试注射过三种DC疫苗,却还是未能逃出死神的魔掌,请从免疫学的角度分析导致他死亡的可能原因是:________________________________________。
