Transcriptomic And Epigenomic Profiling Of Immune Cells Responses To Simian Immunodeficiency Virus Infection In The Brain, Xiaoke Xu

Theses & Dissertations

Human immunodeficiency virus type 1 (HIV-1) is an enveloped retrovirus that significantly impairs the human immune system. A common complication of HIV-1 infection is HIV-associated neurocognitive disorder (HAND), which, prior to the introduction of antiretroviral therapy (ART), led to considerable morbidity and mortality due to untreated neuropsychiatric manifestations. Although ART has substantially reduced the incidence of HIV-associated dementia (HAD), approximately 50% of people living with HIV (PLWH) continue to experience milder forms of HAND. The CNS is seeded by HIV during the acute phase of infection. Once in the brain, HIV targets and activates resident immune cells, primarily microglia and …

Faculty, Staff and Students Publications

Esophageal adenocarcinoma is increasingly prevalent and is thought to arise from Barrett's esophagus (BE), a metaplastic condition in which chronic acid and bile reflux transforms the esophageal squamous epithelium into a gastric-intestinal glandular mucosa. The molecular determinants driving this metaplasia are poorly understood. We developed a human BE organoid biobank that recapitulates BE's molecular heterogeneity. Bulk and single-cell transcriptomics, supported by patient tissue analysis, revealed that BE differentiation reflects a balance between SOX2 (foregut/esophageal) and CDX2 (hindgut/intestinal) transcription factors. Using squamous-specific inducible Sox2-KO (Krt5CreER/+ Sox2Δ/Δ ROSA26tdTomato/+) mice, we observed increased basal proliferation, reduced squamous differentiation, and expanded metaplastic glands at …


The Speech-To-Song Illusion Across Development And The Effects Of High-Level Expectations, Rodica R. Constantine Aug 2025

The Speech-To-Song Illusion Across Development And The Effects Of High-Level Expectations, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical listener can readily categorize auditory stimuli as either speech or song even though these structures share many acoustic similarities. These musical and linguistic categories may nevertheless take time to develop as children acquire language- and music-specific knowledge. In the Speech-to-Song (STS) illusion, multiple repetitions of a natural spoken utterance can give rise to a perceptual switch wherein the stimulus begins to sound song-like to the listener. While the STS illusion has been well-researched in adult listeners, it had yet to be investigated in children. In our study, we examined whether children experience the STS illusion by presenting participants …

The gut microbiome has emerged as a key regulator of response to cancer immunotherapy. However, a better understanding of the underlying mechanisms by which the microbiome influences immunotherapy is needed to identify strategies to optimize outcomes. To this end, we developed a mathematical model to obtain insights into the effect of the microbiome on the immune system and immunotherapy response. This model was based on (i) gut microbiome data derived from preclinical studies, (ii) mathematical modeling of the antitumor immune response, (iii) association analysis of microbiome profiles with model-predicted immune profiles, and (iv) statistical models that correlate model parameters with …

Background: The prognostic impact of Fms-like tyrosine kinase 3 (FLT3)-tyrosine kinase domain (TKD) mutation in patients with acute myeloid leukemia (AML) is not well defined. The authors described outcomes of one of the largest cohorts of patients with FLT3-TKD mutated (FLT3-TKDmut) AML to date.

Methods: This retrospective study included patients with newly diagnosed AML who received frontline treatment at The University of Texas MD Anderson Cancer Center from January 2012 to March 2024 divided into two cohorts: FLT3-TKDmut AML and nucleophosmin-mutated (NPM1mut)/FLT3-TKD wild-type (FLT3-TKDwt) AML. Patients with FLT3 internal tandem duplication mutations were excluded.

Results: In total, 2922 patients were …

Substance use disorder (SUD) significantly increases the risk of neurotoxicity, inflammation, oxidative stress, and impaired neuroplasticity. The activation of inflammatory pathways by substances may lead to reactive astrogliosis and chronic neuroinflammation, potentially mediated by the release of extracellular particles (EPs), such as extracellular condensates (ECs) and extracellular vesicles (EVs). These particles, which reflect the physiological, pathophysiological, and metabolic states of their cells of origin, might carry molecular signatures indicative of SUD. In particular, our study investigated neuroinflammatory signatures in SUD patients by isolating EVs from the dorsolateral prefrontal cortex (dlPFC) Brodmann's area 9 (BA9) from postmortem subjects. We isolated BA9-derived …
