We found significantly higher estimates of eosinophils, macrophages M1, neutrophils, CD4+ naive T cells, and plasmacytoid DC (pDC) in SCC with high immune score and more gamma delta T cells (Tgd cells), conventional DC (cDC), mast cells, NK cells, CD4+ T cells, DC, activated DC (aDC), type 2 T‐helper cells (Th2 cells), and CD4 memory T cells in AD with high immune score. Here, CD4 is linked to Alzheimer disease.
