不变自然杀伤T(iNKT)细胞包括在胸腺中发育的先天淋巴细胞亚群。一种新的模型提出将鼠iNKT细胞细分为iNKT 1、2和17细胞。在这里,我们使用从BALB/c和C57 BL/6胸腺分离的iNKT 1,2和17亚群的转录组分析,以确定可能影响iNKT细胞发育,迁移或功能的候选基因。我们发现,Fc γ r1γ参与iNKT 1细胞的生成,SerpinB 1调节iNKT 17细胞的频率。此外,相当大比例的iNKT 17细胞同时表达IL-4和IL-17。这些结果不仅验证了iNKT 1/2/17概念的有效性,而且为iNKT细胞生物学提供了新的见解。 恒定自然杀伤T细胞(iNKT)细胞生物学的最新进展是将其分类为iNKT 1,iNKT 2和iNKT 17亚群。在这里,作者提供了来自Balb/c和C57 Bl/6小鼠的这些胸腺亚群的转录组学分析,支持并扩展了分类。
Invariant natural killer T (iNKT) cells comprise a subpopulation of innate lymphocytes developing in thymus. A new model proposes subdividing murine iNKT cells into iNKT1, 2 and 17 cells. Here, we use transcriptome analyses of iNKT1, 2 and 17 subsets isolated from BALB/c and C57BL/6 thymi to identify candidate genes that may affect iNKT cell development, migration or function. We show that Fcɛr1γ is involved in generation of iNKT1 cells and that SerpinB1 modulates frequency of iNKT17 cells. Moreover, a considerable proportion of iNKT17 cells express IL-4 and IL-17 simultaneously. The results presented not only validate the usefulness of the iNKT1/2/17-concept but also provide new insights into iNKT cell biology. A recent advance in invariant natural killer T cell (iNKT) cell biology is their classification into iNKT1, iNKT2 and iNKT17 subsets. Here the authors provide a transcriptomic analysis of these thymic subsets from Balb/c and C57Bl/6 mice that supports and extends the categorization.
