In a screening of macrophage-related markers by immunohistochemical staining, Komohara et al. reported that the densities of Iba1+ (M1/M2), CD163+ (M2), and CD204+ (M2) TAMs were positively correlated with each other, and that the density of CD163+ TAMs was high in older patients or those with a smaller tumor size [52]. The gene discussed is CD163; the disease is neoplasm.
