Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham Jan 2022

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham

SURF Posters 2022

Schwann cells are a type of glial cell in the peripheral nervous system that produce the myelin sheath surrounding neuronal axons. This myelin insulates the neurons and promotes the rapid conduction of electrical impulses throughout the body. Schwann cells have also been found to play a critical role in neuron repair following nerve injury. During nerve injury, the myelin sheath is damaged, stimulating Schwann cells to release cytokines, or inflammatory mediators, that recruit immune cells to the site of injury so that the myelin debris can be cleared, and repair can take place.1 Then neuronal growth is facilitated by heregulin …

Investigating Mechanisms Of Injury And Intervention In A Novel In Vitro Model Of Traumatic Brain Injury In Organotypic Hippocampal Slice Cultures, Julia Elaine Jagielo-Miller Jan 2022

Investigating Mechanisms Of Injury And Intervention In A Novel In Vitro Model Of Traumatic Brain Injury In Organotypic Hippocampal Slice Cultures, Julia Elaine Jagielo-Miller

Theses and Dissertations--Psychology

Traumatic brain injuries (TBIs) impact millions of individuals each year and can pose long term consequences. Despite numerous attempts, no medication has been approved by the FDA to treat TBIs. The causes of these failed trials are multifaceted, but in part can be attributed to the complex nature of TBIs, as well as a lack of sufficient pre-clinical data. In vitro models of TBI are an important tool to help understand the cellular changes seen following the injury, in a highly controlled environment. For the following experiments, a novel model of TBI was used to injure organotypic hippocampal slice cultures, …

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters Jan 2022

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters

Animal Sentience

Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.

An Investigation Into The Mechanism Of Proteasome Dysfunction In Neurodegenerative Disease And The Biological Impact Of Proteasome Hyperactivation In C. Elegans, Raymond T. Anderson

Aging is an inevitable process that occurs as humans grow older. It is characterized by the chronological accumulation of cellular damage over time leading to functional decline as an organism grows older. Several processes are thought to contribute to the aging phenomenon, but one of the most prolific of these is the disruption of protein homeostasis (proteostasis). The collapse of proteostasis can lead to accelerated aging and the development of age-related diseases including devastating neurodegenerative diseases (NDs) like Alzheimer and Parkinson disease. Virtually all NDs are characterized by the buildup of proteins in and around neurons resulting in neuronal death …

Development Of Fluorescence Based Approaches To Understand Astrocyte Biology In The Context Of Nicotine And Nicotinic Receptor Activity, Surya P. Aryal Jan 2022

Development Of Fluorescence Based Approaches To Understand Astrocyte Biology In The Context Of Nicotine And Nicotinic Receptor Activity, Surya P. Aryal

Smoking and tobacco use (STU) is a major global health problem and worldwide more than six million people die due to tobacco related diseases each year. Although majority of smokers try to quit smoking several times in their life, traditional therapeutic approaches, which focus only on neuronal cells, have a very low success rate. Understanding the effect of nicotine on glial cells, synaptic communication and blood vasculature in the brain can provide further insights on the neurobiology of substance abuse and can potentially help to design better therapeutic approaches. Glial cells are non-excitable cells in the brain which do not …
