Fig. 2From: Absence of endothelial α5β1 integrin triggers early onset of experimental autoimmune encephalomyelitis due to reduced vascular remodeling and compromised vascular integrityImpact of endothelial α5 integrin deletion on EAE development. a. Confirmation of the absence of α5 integrin expression in spinal cord endothelial cells in α5-EC-KO mice. Frozen sections of spinal cord taken from disease-free or pre-symptomatic EAE mice were processed for dual-IF for CD31 (AlexaFluor-488) and α5 integrin (Cy-3). Scale bar = 100 μm. Note that in contrast to WT spinal cord where strong upregulation of endothelial α5 integrin was observed, vessels in α5-EC-KO mice showed total lack of α5 integrin. b. The impact of endothelial α5 integrin deletion on clinical severity in EAE. The progression of EAE in α5-EC-KO and WT littermate control mice was evaluated by measuring clinical score on daily intervals. All points represent the mean ± SEM (n = 3 experiments, with 6–10 mice of each strain used per experiment). Note that compared to WT littermates, α5-EC-KO mice showed markedly earlier onset and faster progression of EAE. * p < 0.05 vs. WT.Back to article page
