In contrast, a lower degree of infiltration was found in 8 immune cell subpopulations in inflamed IBD tissue, including monocytes, activated NK cells, resting dendritic cells, M2 macrophages, gamma delta T cells, follicular helper T cells, CD8 T cells, and CD4 memory resting T cells in IBD inflamed tissue (p < 0.05). The gene discussed is CD8A; the disease is inflammatory bowel disease.
