Connecting cellular mechanisms and.extracellular vesicle cargo in traumatic brain injury

Traumatic brain injury is followed.by a cascad. of d.namic and.complex events occurring at the cellular level. These events includ.: d.ffuse axonal injury, neuronal cell d.ath, blood.brain barrier break d.wn, glial activation and.neuroinflammation, ed.ma, ischemia, vascular injury, energy failure, and.peripheral immune cell infiltration. The timing of these events post injury has been linked.to injury severity and.functional outcome. Extracellular vesicles are membrane bound.secretory vesicles that contain markers and.cargo pertaining to their cell of origin and.can cross the blood.brain barrier. These qualities make extracellular vesicles intriguing cand.d.tes for a liquid.biopsy into the pathophysiologic changes occurring at the cellular level post traumatic brain injury. Herein, we review the most commonly reported.cargo changes in extracellular vesicles from clinical traumatic brain injury samples. We then use knowled.e from animal and.in vitro mod.ls to help infer what these changes may ind.cate regrad.ng cellular responses post traumatic brain injury. Future research should.prioritize labeling extracellular vesicles with markers for d.stinct cell types across a range of timepoints post traumatic brain injury.
