The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski
The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski
Biomedical Sciences ETDs
Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Synaptic plasticity is the ability of the brain to make changes and the changes occur at synapses. To achieve the complicated functions, a good number of proteins are present at synapse and are called synaptic proteins. To stabilize these proteins at synapses, proteins are modified through posttranslational modifications (PTMs). The most studied PTMs include phosphorylation, acetylation, ubiquitination, glycosylation, palmitoylation, etc. Palmitoylation is a type of lipid modification and has received more attention recently for its contribution to protein trafficking, localization, and interaction in various synaptic plasticity. The membrane-associated guanylate kinase (MAGUK) family includes PSD-95, PSD-93 (also known as chapsyn-110), SAP102, …

ipRGCs are retinal ganglion cells that project to visual processing centers of the brain for nonimage forming visual functions. The relation of ipRGCs to tramatic brain injury (TBI) is emerging as data has been published describing ipRGC functional changes in TBI affected military veterans. Major symptomologies of concussions, a mild form of TBI, also overlap with the function governed by sites in the brain with major ipRGC projection percentages. Assesing if a morphological change is occuring in the ipRGCs after a TBI could support the idea of a pathological mechanism of the injury. This study could also indicate further relevance …
