Interestingly, when only obese patients with T2DM and EC are evaluated, a non-significant increase in CD3+ T-cells (105 vs. 52 cells/mm2 epithelium, p = 0.199) and a significant increase in intraepithelial CD8+ T-cells (144 vs. 50 cells/mm2 epithelium, p = 0.046) was in seen in obese diabetic patients compared to lean patients with EC, despite the small number of patients (Figure 3C, Supplementary Table S4). The gene discussed is CD8A; the disease is type 2 diabetes mellitus.
