Meningeal B Cells In Central Nervous System Autoimmunity: Their Phenotype And Susceptibility To Therapeutic Depletion, Yodit Tesfagiorgis

B cell depleting therapies have been effective in the treatment of Multiple Sclerosis (MS), yet to date little is known about how B cells promote disease pathogenesis. B cells can be found invading the meninges around the brain and spinal cord in MS, where they cluster in association with T cells. These meningeal B cells clusters are often adjacent to demyelinating lesions suggesting this may be a site where B cells are exerting their pathogenic effects. The purpose of this thesis was to understand the contribution of meningeal B cells to central nervous system (CNS) autoimmunity, by characterizing their phenotype …

Brain-Specific And Systemic Inflammatory Response Following Repetitive Concussive Impact In A Mouse Model, So Young Eo

Concussion is the most common form of mild traumatic brain injury (mTBI). TBI resolution is modulated by neuroinflammation, which is augmented by the infiltration of innate immune cells from the circulation. Peripheral, myeloid immune cells not only invade neural tissues but other organs as well causing local inflammation and tissue damage, known as systemic inflammatory response syndrome. Here, I assessed the temporal and anatomical nature of the neural and systemic cellular inflammatory response to repetitive, mTBI in a 3-hit mouse model of concussion. The results showed significant microglial activity, accumulation of peripheral myeloid cells and prominent axonal damage post-injury. The …

Concussions are generating increasing concern due to potential long-term neurological consequences. Currently there is no universally recognized diagnostic approach for concussion. I hypothesize that a signature temporal response of biomarkers of inflammation in systemic circulation will provide an objective diagnosis of concussion and could also be used to track patient recovery. The Western University women’s rugby team underwent blood draws at pre-season and post-season as a baseline evaluation, and players determined to have sustained a concussion underwent repeat blood analysis post-concussion. Blood samples were analyzed by flow cytometry to profile immune cell populations alongside accepted concussion assessments, and complete blood …
