This was the case for all CD103-expressing cells including γδ T cells in IEL, CD8+ Trm in IEL and LPL, and CD4+ Trm in LPL, proportions of which in CRC samples represented on average 14%, 15%, 9.0% and 5.5% of those in healthy donors, respectively. This evidence concerns the gene CD8A and colorectal carcinoma.
