Description
We report the transcriptome analysis of epidermal CD8 tissue resident memory T (TRM) cells from healthy human skin. Specifically, epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells from healthy human skin were sorted by FACS. Differential gene expression analysis revealed functional dichotomy of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells. Overall design: Analysis of differentially expressed genes between epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- T cells from healthy human skin, biological replicates (n=7) (healthy skin donors).

Description
Mucosa-associated invariant T (MAIT) cells are unconventional innate-like T cells that recognize microbial riboflavin metabolites presented by the MHC class I-like protein MR1. Human MAIT cells predominantly express the CD8a co-receptor (CD8+), with a smaller subset lacking both CD4 and CD8 (DN). However, it is unclear if these two MAIT cell sub-populations distinguished by CD8a represent functionally distinct subsets. To address this, we investigated the phenotypic, transcriptional, and functional differences between CD8+ and DN MAIT cells using human samples from peripheral blood, mucosal tissues, and fetal tissues. Overall design: We FACS sorted CD8+ and CD8- MAIT cells from human peripheral blood and performed bulk RNAseq on these cells
Publication Title
The CD4<sup>-</sup>CD8<sup>-</sup> MAIT cell subpopulation is a functionally distinct subset developmentally related to the main CD8<sup>+</sup> MAIT cell pool.
