Understanding the Neuroimmunology of Aging and Traumatic Brain Injury

Heterogeneity of pathoanatomical subtypes and diversity in the extent of injury contribute to differences in the pathogenesis of TBI. Although this heterogeneity can be influenced by many variables including sex and genetic variability; age and aging related processes remain key factors that determine the clinical outcomes after TBI. Alongside age, there is a growing consensus that neuroinflammation plays a key role in determining the pathophysiology of TBI. Given neuroinflammation can be detrimental or beneficial, before developing immunomodulatory therapies, it is necessary to better understand the timing and complexity of the neuro-immune responses that follow TBI. Dr. Main will present data displaying the temporal progression of secondary injury cascades including blood brain barrier dysfunction, and the secretion of pro-inflammatory cytokines and chemokines by resident microglial and astrocyte populations after injury. In addition, he will show how meningeal lymphatics link the brain and periphery and play an important bi-directional inflammatory role, with particular involvement in the drainage of immune cells after TBI. Finally, he will evidence how these combined responses are exacerbated with age, and discuss the implications of these findings in the broader context of secondary injury in TBI, and TBI-induced neurodegenerative disease.

Human Tau Isoform Expression Alters Acute and Chronic Progression of Traumatic Brain Injury

Brain injury is compared in knock-in mice (MAPTKI) that express all 6 human tau isoforms using the mouse tau promotor with wild-type mice that express 3 mouse tau isoforms. At 14 days post-injury, wild-type mice have axonal injury, demyelination and cognitive deficits. Many cognitive deficits in injured wild-type mice resolve by 90 DPI. In contrast, at 14 days post-injury, MAPTKI mice have less white matter injury and lack the cognitive deficits in wild-type mice. At 90 DPI, MAPTKI mice develop cognitive and memory deficits not present in wild type. Thus, expression of human tau greatly changes disease course in MAPTKI mice after a single closed head injury.

White Matter Pathology in TBI: Clues to Therapeutic Ppportunities for Intervention

Traumatic brain injury can produce white matter pathology that involves axon damage and demyelination, as well as neuroinflammation and vascular injury. Long axons in white matter tracts are especially vulnerable to damage from TBI. Axon signal conduction is highly sensitive to disruption of axon-myelin interactions. Myelination also provides trophic and metabolic support for axon function and survival. This talk will use neuroimaging, structural and molecular data to demonstrate a range of axon and myelin pathological features in white matter injury across times post-injury. Importantly, this data broadens the population of axons involved and reveals additional opportunities for therapeutic intervention to protect axons and promote recovery of function after traumatic axonal injury.

Prevention, Prognostication, and Problems in Managing Pediatric Mild Traumatic Brain Injury

Rebekah Mannix, MD, MPH, Professor of Pediatrics & Emergency Medicine, Harvard Medical School

Prevention is the Best Medicine for Youth Concussion

This presentation will discuss fundamentals in concussion prevention with an emphasis on the following topics:

  • Can equipment prevent concussions?

  • Is there a biomechanical threshold for injury?

  • Are head impact sensors a useful tool to understand exposure?

  • What are other characteristics of a prevention-focused view of concussions?

You Injure the Body You Have: Implication of Body Habitus on Inflammatory Response and Recovery from Mild Traumatic Brain Injury

Obesity is a disease state which is associated with chronic circulatory inflammation and numerous baseline comorbidities. These conditions have the potential to increase short- and long-term inflammatory responses to physical trauma in comparison to a normal mass patient. Higher acute inflammatory markers predict worse outcomes from mild traumatic brain injury (mTBI). To date, little is known about the role of baseline (at time of injury) obesity and outcomes from mTBI. The purpose of this presentation is to describe differences in inflammatory response to mTBI between obese and non-obese patients and the association between inflammatory response, comorbid health conditions, and long-term outcomes following the injury.

The Utility of Acute Neurotrauma Biomarkers

Ava Puccio, RN, Ph.D., Associate Professor of Neurological Surgery, Co-Director Neurotrauma Clinical Trials Center, University of Pittsburgh

Blood-Based Biomarkers of Epileptogenesis after Traumatic Brain Injury; Clinical Studies

Post-traumatic epilepsy (PTE) is one of the major complications following severe traumatic brain injury. The epileptogenic process leading to PTE is currently poorly understood but likely multifactorial and crosses multiple modalities. Without a full understanding of the underlying pathobiological process, there will be no cures for PTE. Identifying blood borne protein biomarkers of the TBI-induced epileptogenic process provide not only diagnostic and prognostic information but also help to identify potential molecular targets for developing therapeutic interventions. Dr. Agoston will present blood-based biomarker data identified in the clinical studies from the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx). EpiBioS4Rx is an NINDS-funded international, multicenter Center without Walls (CWOW) research program with the objectives of developing the techniques to identify biomarkers to determine patient populations at risk and likely to benefit from PTE prevention therapies, rendering such future clinical trials cost-effective. He will discuss the power of using Machine Learning in analyzing and interpreting blood borne protein biomarker data to identify pathobiologies underlying the development of PTE, high-risk individuals, and identifying disease modifying therapies.

Neurologic Function Across the Lifespan: A Prospective, Longitudinal, and Translational Study of Former NFL Players

(NFL-LONG) has assessed a cohort of former National Football League players, some for as long as 20 years. In this update, Dr. Meehan will discuss their current health-related quality of life, how it compares to age matched men in the general population, and describe associations between the concussions they sustained and their current health related quality of life measures. He will discuss murine models of repeated concussions and the potential for future therapies. He will also briefly discuss the future plans of the study.
