Among the immune cell populations, mainly CD14 positive cells (e.g., monocytes) and several different natural killer (NK) cell populations (especially NK1 and NK2 [7,30]) in the tumor tissue, blood, and ascites were underrepresented in Nectin 4 positive tumors and were significantly correlated to many sub-networks and clusters (cf.Figure 5). Here, NECTIN4 is linked to neoplasm.
