Jacob Goldstein: 本期节目探讨了麻疹病毒对人体免疫系统的影响,以及利用麻疹病毒治疗癌症的可能性。麻疹病毒不仅会导致发烧和皮疹等症状,还会对免疫系统造成严重损害,导致免疫记忆丧失,使人更容易感染其他疾病。 Michael Mina: 我在哈佛大学任教期间的研究表明,麻疹疫苗接种后儿童死亡率下降幅度远超预期,这表明麻疹对免疫系统的影响可能比我们想象的要大。麻疹会攻击儿童的免疫记忆,降低他们对其他感染的抵抗力。麻疹会导致免疫记忆丧失(免疫性遗忘),使人更容易感染其他疾病。死于其他疾病的儿童中,约有一半的死亡可能归因于麻疹引起的免疫性遗忘。麻疹通过独特的细胞机制攻击免疫系统,导致免疫记忆丧失。麻疹的研究促进了我们对病毒、免疫系统以及它们之间相互作用的更深入理解。 Stephen Russell: 我长期致力于研究如何利用病毒治疗癌症。麻疹病毒可以被用来治疗癌症。麻疹感染可能导致肿瘤消退。麻疹疫苗株在实验室培养过程中适应了癌细胞,并失去了引起麻疹的能力。麻疹病毒治疗多发性骨髓瘤的疗效因人而异,部分患者疗效显著,部分患者疗效不佳。患者体内缺乏抗麻疹抗体,但存在抗麻疹T细胞,这可能是麻疹病毒治疗多发性骨髓瘤成功的关键因素之一。为了克服麻疹病毒治疗癌症的免疫障碍,研究人员正在探索使用其他病毒或对麻疹病毒进行修饰。病毒疗法在治疗某些癌症方面显示出前景,但仍处于发展阶段。

Deep Dive

Chapters
This chapter explores the surprising and devastating effects of measles beyond the typical rash and fever. Research reveals measles's ability to cause "immune amnesia," significantly increasing vulnerability to other infections and contributing to a substantial number of childhood deaths.
  • Measles causes "immune amnesia", significantly weakening the immune system.
  • Measles outbreaks lead to increased deaths from other infectious diseases in subsequent years.
  • The measles virus attacks immune memory cells (B cells and T cells), wiping away years of built-up immunity.

Shownotes Transcript

We thought we knew everything there was to know about measles. But in recent years, new research has revealed that the virus attacks the immune system and creates effects far more dramatic than a rash and fever. For this episode we’re joined by Michael Mina, a former Harvard epidemiologist now at eMed, who helped discover how measles was causing “immune amnesia.” Our second guest is Stephen Russell, a former Mayo Clinic researcher who co-founded a company called Vyriad. Russell is trying to use the measles virus to treat cancer. Enjoy this episode from Incubation), another Pushkin podcast.
