弥漫性鼻相关淋巴组织 (d-NALT) 的淋巴细胞在呼吸道病原体的进入点具有独特的定位,但在鼻内 (i.n.) 疫苗接种或感染后很少进行检查。在这里我们评估一个 i.n.接种仙台病毒 (SeV),以诱导 d-NALT 中病毒特异性抗体形成细胞 (AFC) 和 CD8+ T 细胞。病毒特异性 AFC 和 CD8+ T 细胞均在接种 SeV 后第 7 天出现,并持续了 8 个月,这解释了该疫苗对呼吸道病毒攻击具有长期持续的保护作用。 AFC 产生 IgM、IgG1、IgG2a、IgG2b 和 IgA,而 CD8+ T 细胞具有溶细胞作用并产生低水平的细胞因子。病毒特异性 T 细胞的表型分析揭示了与肠道中病原体特异性免疫反应的惊人相似性,突出了粘膜部位适应性免疫的一些关键特征。
Lymphocytes of the diffuse nasal-associated lymphoid tissue (d-NALT) are uniquely positioned to tackle respiratory pathogens at their point-of-entry, yet are rarely examined after intranasal (i.n.) vaccinations or infections. Here we evaluate an i.n. inoculation with Sendai virus (SeV) for elicitation of virus-specific antibody forming cells (AFCs) and CD8+ T cells in the d-NALT. Virus-specific AFCs and CD8+ T cells each appeared by day 7 after SeV inoculation and persisted for 8 months, explaining the long-sustained protection against respiratory virus challenge conferred by this vaccine. AFCs produced IgM, IgG1, IgG2a, IgG2b and IgA, while CD8+ T cells were cytolytic and produced low levels of cytokines. Phenotypic analyses of virus-specific T cells revealed striking similarities with pathogen-specific immune responses in the intestine, highlighting some key features of adaptive immunity at a mucosal site.
