CD163 and neoplasm: Interestingly, tumors displaying low densities of CD8+ cells in both tumor regions (i.e., CD8LL; n = 48) were vastly co-infiltrated by low numbers of CD163+ or FoxP3+ cells (CD163LL: n = 21 of 48; FoxP3LL: n = 20 of 48; total: 41 of 48; 85.4%), whereas tumors displaying high densities of suppressor elements (i.e., either CD163HH or FoxP3HH) could be detected only in a restricted number of patients (n= 7 of 48; 14.6%) (Figure 2B).
