Abstract

Traumatic brain injury (TBI) is a serious global health concern, many individuals live with TBI-related neurological dysfunction. A lack of biomarkers of TBI has impeded medication development. To identify new potential biomarkers, we time-dependently evaluated mouse brain tissue and neuronally derived plasma extracellular vesicles proteins in a mild model of TBI with parallels to concussive head injury. Mice (CD-1, 30–40 g) received a sham procedure or 30 g weight-drop, and were euthanized 8, 24, 48, 72, 96 hours, 7, 14 and 30 days later. We quantified ipsilateral cortical proteins. Many of them differed from 8 hours onwards post mTBI compared to sham, 23 proteins changed in 4 or more of 8 different time points. Gene ontology pathways mapped from altered proteins over time related to pathological and physiological processes. Further validation of proteins identified in this study may provide utility as treatment response biomarkers.
