CD163 and ischemic stroke: The percentage of CD163+/CD16+ events 24 h after an ischemic stroke was positively associated with the National Institute of Health Stroke Scale (NIHSS) score (Figure 4a; r  =  0.39, p  =  0.05) and the modified Rankin Scale (mRS) at admission (Figure 4b; r  =  0.39, p  =  0.047), suggesting that stroke severity and disability are relevant triggers for the expression of CD163+ on circulating CD16+ monocytes.
