Investigating The Effects Of Maternal Immune Activation On Sensory Processing: Timing, Immune Mechanisms, And Gene-Environment Interactions, Faraj Haddad

Electronic Thesis and Dissertation Repository

Maternal infection during the first or second trimester of pregnancy poses a risk factor for the child to have neurodevelopmental disorders like autism spectrum disorder (ASD) and schizophrenia. Various clinical and preclinical studies have shown that the maternal immune response to infection, also known as maternal immune activation (MIA), can disrupt fetal brain development.

Over the past two decades, MIA has been studied in rodents using the Polyinosinic Polycytidylic acid (Poly I:C) rodent model. Poly I:C has a molecular pattern resembling viruses that can induce a robust immune response. Following exposure to Poly I:C MIA, rodent offspring exhibit many brain …

The Effects Of Two Novel Anti-Inflammatory Compounds On Prepulse Inhibition And Neural Microglia Cell Activation In A Rodent Model Of Schizophrenia, Heath W. Shelton

Electronic Theses and Dissertations

Recent studies have shown elevated neuroinflammation in a large subset of individuals diagnosed with schizophrenia. A pro-inflammatory cytokine, tumor necrosis factor-alpha (TNFα), has been directly linked to this neuroinflammation. This study examined the effects of two TNFα modulators (PD2024 and PD340) produced by our collaborators at P2D Bioscience, Inc., to alleviate auditory sensorimotor gating deficits and reduce microglial cell activation present in the polyinosinic:polycytidylic (Poly I:C) rodent model of schizophrenia. Auditory sensorimotor gating was assessed using prepulse inhibition and microglial activation was examined and quantified using immunohistochemistry and confocal microscopy, respectively. Both PD2024 and PD340 alleviated auditory sensorimotor gating deficits …
