The Effect Of Age On Neurological Inflammation To Acute Sleep Fragmentation In Mice, Molly Taylor
The Effect Of Age On Neurological Inflammation To Acute Sleep Fragmentation In Mice, Molly Taylor
Mahurin Honors College Capstone Experience/Thesis Projects
Obstructive sleep apnea is identified by recurring events of airway collapse during sleep, intermittent hypoxia, and perturbations in sleep continuity, known as sleep fragmentation. There is evidence to suggest that elderly patients are more at risk of developing obstructive sleep apnea. The purpose of this study was to assess whether age affects neurological inflammatory responses to acute sleep fragmentation. This assessment was made by subjecting young (4-5 months old) and old (10-11 months old) male C57BL/6j mice to automated sleep fragmentation, as well as having mice in both age categories as a control with no sleep fragmentation, for twenty-four hours. …

Background: The migration of peripheral immune cells and splenocytes to the ischemic brain is one of the major causes of delayed neuroinflammation after permanent large vessel stroke. Other groups have demonstrated that leukemia inhibitory factor (LIF), a cytokine that promotes neural cell survival through upregulation of antioxidant enzymes, promotes an anti-inflammatory phenotype in several types of immune cells. The goal of this study was to determine whether LIF treatment modulates the peripheral immune response after stroke.
Methods: Young male (3 month) Sprague-Dawley rats underwent sham surgery or permanent middle cerebral artery occlusion (MCAO). Animals were administered LIF (125 μg/kg) or …

Damage to the skin initiates a cascade of well-orchestrated events that ultimately leads to repair of the wound. The inflammatory response is key to wound healing both through preventing infection and stimulating proliferation and remodeling of the skin. Mast cells within the tissue are one of the first immune cells to respond to trauma, and upon activation they release pro-inflammatory molecules to initiate recruitment of leukocytes and promote a vascular response in the tissue. Additionally, mast cells stimulate collagen synthesis by dermal fibroblasts, suggesting they may also influence scar formation. To examine the contribution of mast cells in tissue repair, …
