Pre-Pulse Inhibition In Mutated Mice: Studying Compromised Microglial Cells To Discover New Genetic Connections To Autism, Bailey R. Kramarik

Senior Honors Projects, 2020-current

Microglial cells “play a pivotal role in refining neural networks during early critical periods” (Gabriele & Gray, 2020, p. 1). A disturbance in the functioning of these microglial cells contribute to specific characteristics of some neurodevelopmental disorders- including autism spectrum disorder. In this study, we used a mouse model to study disruptions in cell activity, as understanding the biological and genetic background of autism spectrum disorder could help us provide better treatment and therapy options to those diagnosed.

The mutated mice in this experiment have microglial cells with “compromised fractalkine signaling” (Gabriele & Gray, 2020, p. 4-5). We studied multimodal …

Effect Of Propionic Acid-Derivative Ibuprofen On Neural Stem Call Differentiation; A Potential Link To Autism Spectrum Disorder, Aseelia Samsam

Honors Undergraduate Theses

Propionic acid (PPA) is a short chain fatty acid that is produced by the human gut microbiome. Propionate, butyrate and acetates are the end products of the fermentation of the complex carbohydrates by human gut friendly microbiome and are being used as sources of energy in our body. PPA is used as a food preservative against molds in various daily products and has been implicated in the pathogenesis of autism. In a recent study we showed that PPA in human neuronal stem cell (NSC) culture increases the astrocyte population and decreases the neuronal number and increases the inflammatory cytokines. In …

Investigation Of Behavioral And Cellular Changes In The Maternal Immune Activation Model Of Autism Spectrum Disorders, Shreya Roy

Theses & Dissertations

Maternal infection during pregnancy, which leads to maternal immune activation (MIA), is an environmental risk factor for autism spectrum disorders (ASD). MIA can be induced in mice and their offspring exhibit behaviors that model the core symptoms of ASD. One of the core behavioral symptoms in ASD patients is presence of increased repetitive behavior, which is modeled by an increase in marble burying in MIA mice. It has been shown that the deficits seen in MIA mice are associated with the dysregulation of cytokine levels in the developing brain, specifically an increase in pro-inflammatory cytokines. In this thesis, I tested …
