The U.S. Department of Defense Blast Injury Research Coordinating Office Brain Health Coordinator selects an article each month to highlight emerging research accomplishments in blast-related brain health topics including, but not limited to biomarkers, blast-related TBI, blast-related nerve injury, and modeling of the brain, spinal cord, and nerves.
Traumatic brain injuries are associated with some of the poorest outcomes in clinical practice. Such injuries can arise from blunt (closed) or penetrating trauma (open/pTBI). An injury track created by a foreign body (e.g. fragments or gunshot rounds) causes cavitation, shearing, and compression of nerve fibers and blood vessels, with damage to neurons and glia including myelin damage. The post-injury response mounted by multiple neural cell types includes microglial activation and astroglial scarring with the expression of a range of growth inhibitory molecules and cytokines in the lesion environment.
