Gastrointestinal Alterations In Two Mouse Models Associated With Social Behavior Deficits, Gracie Leamon
Gastrointestinal Alterations In Two Mouse Models Associated With Social Behavior Deficits, Gracie Leamon
Undergraduate Honors Theses
The gastrointestinal (GI) tract is a diverse habitat for multiple microorganisms. Disturbances in the microbiome of the GI tract have been associated with psychiatric disorders including autism spectrum disorder (ASD). Individuals with ASD, when compared to neurotypical individuals, have demonstrated differing gut species. Also, it has been shown that microbial transplant therapies impact ASD symptoms in patients. Animal models of behaviors associated with ASD might offer insight for the actual role these microbial differences may occupy regarding symptoms. Unfortunately, ASD does not have an accepted animal model where the GI alterations have been thoroughly explored. In this study, we sought …
Neuroinflammation, Peripheral Inflammation And Gut Microbiome Profiles In Male Mice From Two Proposed Mouse Models Of Social Behavior Deficits, Sarah Parkinson
Neuroinflammation, Peripheral Inflammation And Gut Microbiome Profiles In Male Mice From Two Proposed Mouse Models Of Social Behavior Deficits, Sarah Parkinson
Electronic Theses and Dissertations
Autism spectrum disorder (ASD) is a neurodevelopmental disorder marked by social deficits and repetitive actions. A communication pathway exists between the brain and gut called the gut-brain axis. It is thought that gut bacteria can secrete signaling molecules, triggering inflammation across the body. These studies attempt to determine if markers are expressed in two mouse models of ASD behaviors, BTBR and a valproic acid model. Immunohistochemistry of ionized calcium binding adaptor molecule 1 from male mouse brain tissue showed no microglial activation in any group. Cytokine analysis did exhibit an increase in interleukin 1 (IL-1) in male adult mice only. …

Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, Kyla Scott
Undergraduate Honors Theses
Autism spectrum disorders (ASD) encompass neurodevelopment disorders characterized by atypical patterns of development that impact multiple areas of functioning beginning in early childhood. The etiology of ASD is unknown and there are currently no preventative treatment options. Gastrointestinal symptoms are commonly associated comorbidities. The microbiota-gut-brain axis is a multidirectional communication chain that connects the central and enteric nervous system that relates brain function to peripheral intestinal functions. Changes within this axis have been postulated in ASD. For example, the “leaky gut theory” proposes that chronic inflammation is linked to alterations in the bacterial profiles of the gut microbiome and subsequent …
