Assessing The Morphology Of Vesicles In Inhibitory Symmetric Synapses In Safety And Fear Conditions In The Rat Lateral Amygdala, Valerie Kress

Honors Scholar Theses

There is a significant lack of research on vesicle morphology in inhibitory synapses in the rat lateral amygdala. Published research focuses heavily on excitatory synapses in different parts of the rat brain and even this research rarely focuses on the different vesicle types in axons. It is reported that in these axons, synaptic vesicles traditionally contain neurotransmitters while small dense core vesicles contain active zone proteins and large dense core vesicles contain neuropeptides. This study aims to find correlations between vesicle morphology, location, contents, and potential function of each of the different types of vesicle in inhibitory axons.

Notch Inhibitors And The Bet Inhibitor Jq-1 Decrease The Growth Of Primary Tumor Cells Derived From A Novel Mouse Model Of C11orf95-Rela Induced Brain Tumor, Ericka Randazzo, Jesse Dunnack, Justin Fang, Joseph Loturco Phd

University Scholar Projects

Brain tumors are the most common childhood solid malignancy, and because of remarkable advances in treating many cancers outside of the brain, they have become the leading cause of cancer mortality in children. Ependymomas are a class of brain tumors which can be further subdivided into three groups based upon their location and genetic features. Of the three classes, supratentorial ependymomas are the only subgroup known to be marked by an oncogenic driver gene, which consists of a fusion mutation between the C11orf95 and RELA genes. C11orf95-RELA positive tumors are the most aggressive and lethal of …

Quantifying Expression Of Interneuron Subtype Markers For Dlx-2 Transfected Ng2 Cells, Timothy Nolan

Honors Scholar Theses

Neurons are a post-mitotic cell population, and therefore, they are not able to regenerate in vivo after a traumatic injury. Because inhibitory GABAergic interneurons and oligodendrocyte precursor cells (OPCs) are derived from the same precursor, recent studies have focused on transforming these OPCs into GABAergic neurons. However, there are different types of GABAergic interneurons that have different electrophysiological responses, which can lead to functional differences. The Nishiyama laboratory had already used a key gene in GABAergic interneuron and OPC differentiation, Distal-less homeobox 2 (Dlx-2), to transfect OPCs; early electrophysiology tests showed most of these transfected cells behaved like immature neurons, …
