CX3CL1 and stroke disorder: In addition to functional outcome, the dynamics of post-stroke microglia response were monitored in vivo by 2-photon-laser-microscopy in heterozygous transgenic CX3CR1-green fluorescent protein (GFP) mice (CX3CR1GFP/+) and complemented with analyses for fractalkine (FKN) and pro-inflammatory cytokines.
