CD163 and dementia: Moreover, the classic and intermediate monocytes of patients with dementia show a significant decrease in the percentage of monocytes expressing CD163, while the decrease in the expression levels of CD206 is mainly observed in classic and non-classic monocytes, when compared with patients without dementia (classic—528.2 vs. 456.2 MFI, p = 0.002; non-classic—752.9 vs. 447.3 MFI, p = 0.008) (Table 5).
