Expression data from mouse spleens after experimental stroke

ABSTRACT: Infection is a major complication and cause of mortality and morbidity after acute stroke however the mechanisms are poorly understood. After experimental stroke the microarchitecture and cellular composition of the spleen are extensively disrupted resulting in deficits to immune function. We used microarray to determine differentially expressed genes in the spleens of mice after experimental stroke to determine contributers to immunosuppression after stroke.

Expression data from mouse spleens after experimental stroke

Project description:Infection is a major complication and cause of mortality and morbidity after acute stroke however the mechanisms are poorly understood. After experimental stroke the microarchitecture and cellular composition of the spleen are extensively disrupted resulting in deficits to immune function. We used microarray to determine differentially expressed genes in the spleens of mice after experimental stroke to determine contributers to immunosuppression after stroke. We extracted RNA from spleens from 3 mice 5 d after experimental stroke when we have shown peak disruption to cellular composition and also from spleens from 2 sham-operated control mice for comparison.

Transfer RNA fragments replace microRNA regulators of the cholinergic post-stroke immune blockade III

Project description:After ischemic stroke, the brain initiates intensive communication with the immune system, and acetylcholine contributes to this process. Stroke triggers peripheral immunosuppression leading to increased susceptibility to infections; and post-stroke pneumonia is linked with poor stroke outcome, but the responsible processes are yet unknown. We discovered a “change of guards” where microRNA levels decreased but small transfer RNA fragments (tRFs) accumulated in post-stroke blood cells. This molecular switch may re-balance acetylcholine signaling in CD14+ monocytes by regulating their gene expression and modulating post-stroke immunity. Our observations point to tRFs as new molecular regulators of post-stroke immune responses that may become potential therapeutic targets.

Transcriptome analysis reveals intermittent fasting-induced genetic changes in ischemic stroke

Project description:Intermittent fasting is previously reported to exhibit neuroprotection against experimental ischemic stroke. However, the detailed understanding of protection mechanisms are lacking. By observing the overall transcriptomic changes in each timepoint of ischemic stroke would benefit the understanding of underlying active pathways and mechanisms. Here, we conduct experimental MCAO ischemic stroke on mice exposed to different daily intermittent fasting method to compare not only among the ischemic stroke timepoints but also the efficacy of different intermittent fasting interventions. Our current study presented the transcriptomic changes for the first time in specific timepoints of ischemic stroke as well as under the condition of intermittent fasting. A number of neuroprotective mechanisms-related genes were significantly affected by intermittent fasting conditions in differential manners.

Single cell RNA sequencing data of brain myeloid cells after experimental stroke

Project description:Acute stroke triggers extensive changes to myeloid immune cell populations in the brain that may be targets for limiting brain damage and enhancing repair. Immunomodulatory approaches will be most effective with precise manipulation of discrete myeloid cell phenotypes in time and space. Here, we investigate how stroke alters mononuclear myeloid cell composition and phenotypes at single-cell resolution and key spatial patterns. Our results show that multiple reactive microglial states and monocyte-derived populations contribute to an extensive myeloid cell repertoire in post-stroke brains. We identify important overlaps and distinctions among different cell types/states that involve ontogeny- and spatial-related properties. Notably, brain connectivity with infarcted tissue underpins the pattern of local and remote altered cell accumulation and reactivity. Our discoveries suggest a global but anatomically governed brain myeloid cell response to stroke that comprises diverse phenotypes arising through intrinsic cell ontogeny factors interacting with exposure to spatially organized brain damage and neuro-axonal cues.
