Abstract
Hematogenous recruitment of monocytes and macrophages has traditionally been viewed as a harmful process causing exacerbation of brain injury after stroke. However, emerging findings suggest equally important protective features. Inflammatory monocytes are rapidly recruited to ischemic brain via a CCR2-dependent pathway and undergo secondary differentiation in the target tissue towards non-inflammatory macrophages, mediating neuroprotection and repair of the ischemic neurovascular unit. In contrast, independent recruitment of non-inflammatory monocytes via CX3CR1 does not occur. Thus, protective features of hematogenous macrophages mainly depend on initial CCR2-dependent cell recruitment. Under therapeutic considerations, specific modulation of monocyte-derived macrophages will therefore be more appropriate than non-selectively blocking their hematogenous recruitment.
