CCR2 and Stroke: Garcia-Bonilla et al. describe that at the first week after stroke, mostly diffused CCR2+ macrophages were observed throughout the ischemic lesion, while during the second and third week after stroke, they saw that CX3CR1+ cells were localized in the peri-infarct area encircling the ischemic lesion core filled with CCR2+ macrophages [39].
