Aberrant Lipid Accumulation And Retinal Pigment Epithelium Dysfunction In Prcd-Deficient Mice, Sree Indrani Motipally

Graduate Theses, Dissertations, and Problem Reports (ETD)

Progressive Rod-Cone Degeneration (PRCD) is a peripheral membrane protein predominantly expressed in photoreceptor outer segment (OS) disc membranes with an unknown function. Several mutations in Prcd are implicated in Retinitis pigmentosa (RP) in humans. The most common “cysteine to tyrosine” (C2Y) mutation in Prcd leads to progressive retinal atrophy in multiple dog breeds and RP in humans. Canine models harboring the C2Y mutation in Prcd show disorganized OS structure with greatly attenuated photoreceptor OS renewal rates. Recent studies show defects in the photoreceptor nascent disc flattening in the absence of Prcd. However, it is unclear how OS discs eventually …

Impulsiveness was determined by performance on a delay-discounting task based on Mok et al. (2020) and the Barratt Impulsivity Scale-11 (BIS-11) Self-control subscale. False confessions were measured based on whether participants orally admitted to a minor wrongdoing. All participants experienced the same study procedure. The false confession paradigm utilized …

Synaptic Zinc Transporters Support Normal Synapse Structure And Function In Mouse Auditory Cortex, Abbey Manning

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many regions of the brain are highly enriched with free zinc inside glutamatergic vesicles at presynaptic terminals. At these synapses, zinc transporter 3 (ZnT3) moves zinc into vesicles where it is co-released with glutamate. Alterations in ZnT3 are implicated in multiple neurodevelopmental disorders, and ZnT3 knock-out (KO) mice – which lack synaptic zinc – show behavioral deficits associated with autism spectrum disorder and schizophrenia. Shank3 is a synaptic scaffolding protein that assists in tethering and organizing structural proteins and glutamatergic receptors in the postsynaptic density of excitatory synapses. The localization of Shank3 at excitatory synapses and the formation of stable …
