Over the summer, my project would be focused on looking at immediate early gene changes following acute cocaine injection. I would be working on my own RNAscope protocol, learning brain slicing, and tissue extraction. I am also interested in sex differences so I would be analyzing males and females. Something I might expect to see is that females have an increased expression for the Fos gene in the combinatorial cells compared to males.

My research for this summer will be focusing on using a human-derived astrocyte cell culture system to model changes in gene expression after acute drug experience seen in vivo. This model will be utilized to determine which neurotransmitter systems, receptors, and cell-signaling cascades are responsible for these transcriptional responses. I will also pilot a novel astrocyte-specific CRISPR/dCas9 tool to bidirectionally manipulate gene targets in astrocytes. This will allow for future investigation of which gene expression changes in astrocytes are necessary for functional changes in cell physiology and drug-seeking behavior in a rodent model system.

The research involves studying low carbohydrate diets and whether they are able to reduce pain and increase the quality of life of amputees. The research will take form in two parts. First, the characterization of pain and psychological wellbeing in amputees will be assessed in addition to dietary habits. Secondly, a low carbohydrate diet will be assessed in whether it can help reduce pain and increase quality of life in amputees.

The SHINE (Sex, Hormones, and Identity affect Nociceptive Expression) Project aims to provide a better understanding of transgender healthcare through the community in our area. The lab I work under conducts research on pain, with a variety of research topics, subjects, and applications. We have previously conducted studies comparing the pain responses of transgender women and cisgender women, and found that the former was phenotypically similar to the latter in all measures. However, hormone levels were not taken into consideration, and transgender men were not included. In SHINE, we will be exploring the pain responses of transgender and cisgender individuals while taking blood samples for the purpose of analyzing stress and reproductive hormones, immune cells, and cytokine release.

For my research project, I want to focus on the stimulated cytokine release. I have worked in gout research in the past, and during that project, we used monosodium urate to artificially stimulate the cytokine response. In this project, the stress is inflicted in vivo, which will introduce many other variables. For my own thesis, I want to be able to study and outline the cytokine release and compare it to the perceived stress of our participants. I want to report on the different types of cytokines and the demographics that express some more than the others. This will allow me to potentially establish a correlation between emotional and/or physical distress with immune markers, which can be extended to a study on the correlation between immune markers and chronic conditions.

My research focuses on determining the relationship between melatonin levels and smoking behaviors. Participants' saliva samples are used to measure their melatonin concentrations throughout different points of their circadian cycle which helps determine how smoking affects circadian characteristics in different races.

My research project will be examining the relationship between perceived discrimination and ratings of daily pain. Discrimination has been indicated to have adverse effects on mental well-being, so I will be looking at whether it influences a physical aspect of health as well.

My research is aiming to establish the basic knowledge and attitudes of people in the Appalachian area on psychedelics and psychedelic assisted therapies. As someone from this region who has seen the impact of the opioid crisis and the lack of mental health care, I am thrilled to be doing research to positively impact my community.

The research project that I am working on will be investigating the differences between idiopathic generalized epilepsy (IGE) patients and age –matched healthy controls (HCs) in diffusion MRI (dMRI) white matter characteristics and fMRI activation during executive attention, as well as their relationships with self-reported physical activity and cognitive function. My role will be analyzing dMRI and flaker task (FT) fMRI in the cross-sectional study of 12 IGE patients and 12 HCs to allow us to examine differences in white matter structural connectivity as well as in attentional processes. Additionally, we will also use Statistical Analysis System (SAS) to perform group statistical analyses with the demographic and behavioral data, and to run correlations and regression analyses to examine relationships between our variables of interest.

My research centers around the study of how the activity of norandrenergic cells in the nucleus of the solitary tract (NTS) is altered in freely behaving animals during free and motivated food consumption. To study this, I am working under my PI, Dr. Hardaway, and other mentors in my lab to record these cells during feeding trials using viral intersection tools and optogenetic recording methods.

My summer research project is focusing on the differences between our Alzheimer’s disease mouse model (5XFAD) and our TFEB overexpressed mice. TFEB is a transcriptional factor that is important in regulating proteostasis and autophagy. Our lab has generated a new line of transgenic mice that overexpress TFEB specifically in their skeletal muscle (cTFEB;HSACre mice), and we have observed marked improvements in brain function through aging. We hypothesize that a secreted factor originating in skeletal muscle can elicit neuroprotective responses in the central nervous system in response to Alzheimer’s disease pathogenesis. We will directly test this hypothesis using a cohort of single transgenic 5XFAD and 5XFAD;cTFEB;HSACre triple transgenic mice. We will measure a battery of established AD biomarkers in pre-symptomatic (3 months) and symptomatic mice (6 months), including intraneuronal amyloid-beta plaques, through tissue staining and ELISAs, as well as markers for neuroinflammation via immunostaining for reactive astrocytes (GFAP) and microglia (Iba1).

The current project I am working on is my undergraduate thesis in partial fulfillment of the requirements for Honors in Psychology. My thesis will focus on examining the impact of chronic pain stigma and HIV stigma on pain interference and depression.

With evidence suggesting that the inhibition of HuR may limit functional damage in neurodegenerative diseases, there is vast potential for application of this drug. Our lab is mainly focused on neuroinflammation in amyotrophic lateral sclerosis (ALS), so I am excited to be able to use this inhibitor this summer on an ALS mouse model and investigate if the results we have seen in the LPS model will translate into the ALS model. In addition to testing this inhibitor on potential anti-inflammatory effects in ALS, I will also be working on a project with Dr. King and Dr. Sorge to determine if this drug may also have an effect on acute and chronic pain. This summer I want to be able to progress my research and understanding on the potential avenues of application for this inhibitor while also expanding my knowledge of these fatal neurodegenerative diseases.

I have two primary goals for my summer research experience. First, I will use single nucleus RNA sequencing datasets of rat NAc, from both repeated and acute exposures to cocaine, to build a single cell atlas. I will use this atlas to test the enrichment of cell type specific genes for genome wide association study (GWAS) phenotypes for neuropsychiatric, neurodevelopmental, and neurodegenerative diseases. As previously mentioned, the Science Advances paper, published by the Day Lab, identified that specific cell types are changed in response to acute cocaine. Thus, my second goal would be to build upon this information and extend findings in a repeated cocaine model, identifying cell type specific transcriptional programs altered by recurrent cocaine exposure. Exploring the brain on a cell-specific level was previously difficult due to its heterogeneous cell type composition. With single nucleus RNA sequencing technology and the platform established by the Day Lab, I believe my work will further develop our understanding of how these cell types contribute to addiction.
