The role of Clec4e (Mincle) in microglia response to transient ischemic injury

ABSTRACT: This data set shows dramatic changes in gene expression in microglia isolated from C57Bl6/J mice subjected to transient middle cerebral artery occlusion, as compared to those subjected to sham surgery. Mice deficient in Mincle (Clec4e-/-) showed significantly improved injury outcomes 3 and 7 days after transient middle cerebral artery occlusion. However, when comparing changes in gene expression in microglia 24 hours after blood reperfusion, there were no differences between wild-type and Clec4e-/- mice, indicating that Mincle does not participate in early microglial activation.

Mice deficient in Mincle (Clec4e-/-) showed significantly improved injury outcomes 3 and 7 days after transient middle cerebral artery occlusion. However, when comparing changes in gene expression in microglia 24 hours after blood reperfusion, there were no differences between wild-type and Clec4e-/- mice, indicating that Mincle does not participate in early microglial activation. Wild type and Mincle knock-out (Clec4e-/-) mice. After 1 h of transient middle cerebral artery occlusion (tMCAO) and 24 h of reperfusion, mice were perfused with PBS, their brains dissected, and 2 ipsilesional hemispheres (with cerebellum and brainstem removed) pooled for microglia isolation. For sham-operated animals, the whole forebrain was used and brains were not pooled. After myelin separation by Percoll gradient centrifugation, around 80,000 CD45intermediate, CD11b+ microglial cells were sorted from each sample. Sham samples n=3, tMCAO samples n=5.

Responses of microglia in the mouse brain after ischemic stroke

Project description:This project investigated responses of microglia in the mouse brain after an ischemic stroke. Mice were subjected to transient focal cerebral ischemia induced by 1 hour of left middle cerebral artery (MCA) occlusion followed by reperfusion. Control mice were subjected to sham surgery without the occlusion of the MCA. Three days after MCA occlusion or sham surgery, microglia were enriched from the brain by fluorescence-activated cell sorting and subjected to bulk RNA-seq. This project was closely related to our previously published dataset GSE141972; therefore, the animals had the same genetic background for comparison purposes. The animals used in this study were hemizygouse for CX3CR1(CreER), so that they can serve as wild-type controls for any conditional knockout driven by the CX3CR1(CreER) promoter.

Stroke-induced transcriptomic alterations in mouse cerebral microvessels

Project description:To investigate the stroke-induced changes in gene expression in cerebral microvessels, we subjected mice to transient middle cerebral artery occlusion (tMCAO) or sham surgeries. 24h hours later, cerebral microvessels were harvested and RNA was isolated. We then performed gene expression profiling analysis using data obtained from RNA-seq of cerebral microvessels isolated from 8 mice (4 shams and 4 tMCAO)

Comparison of microglia of old vs. young ischemic male mice

Project description:We subjected old (21-22 month) and young (3-4 month) male C57BL/6 mice to 45 min transient oclusion of the middle cerebral artery and obtained the brain four days later. We obtained bodipy+ microglia from the ischemic brain tissue by FACS.
