Research outputs 2022 to 2026

Background: Lupus nephritis (LN) is a crucial complication of systemic lupus erythematosus (SLE) and has important clinical implications in guiding treatment. N-glycosylation of immunoglobulin G (IgG) plays a key role in the development of SLE by affecting the balance of anti-inflammatory and proinflammatory responses. This study aimed to evaluate the performance of IgG N-glycosylation for diagnosing LN in a sample of female SLE patients. Methods: This case-control study recruited 188 women with SLE, including 94 patients with LN and 94 age-matched patients without LN. The profiles of plasma IgG N-glycans were detected by hydrophilic interaction chromatography with ultra-performance liquid chromatography …

Interactions Between Hiv And Opioids On Antiretroviral Accumulation, The Blood Brain Barrier, And The Inflammatory Response In The Brain., Kara Rademeyer

Theses and Dissertations

The complex mechanisms related to HIV infection, neurodegeneration, and chronic neuroinflammation collectively describe neuroHIV (Hauser et al. 2007; Chang et al. 2014; Smith et al. 2014). Specifically, opioid abuse, poor penetration of antiretroviral (ARV) drugs, chronic inflammation and neuronal injury/degeneration are all implicated in neuroHIV (Fantuzzi et al. 2003; Letendre et al. 2004; Verani et al. 2005; Duncan and Sattentau 2011; Hong and Banks 2015; Simoes and Justino 2015; Olivier et al. 2018; Murphy et al. 2019; Osborne et al. 2020). For the first time, we demonstrate that morphine, fentanyl, and methadone in vivo alter the brain accumulation of ARVs, …

This article focuses on the two major and the most frequently used harm reduction techniques, Syringe-Service Programs (SSPs) and Opioid Agonist Therapy (OAT). Methods: A comprehensive systematic review was undertaken across multiple international databases during the period of (August-December 2021). For studies conducted before 2005, we used data from a previous published systematic review. Thirty-six studies were included, including studies that had performed HIV testing and had a confirmed …

Relative Adrenal Insufficiency In Sepsis, Dan Hao

Theses and Dissertations--Pharmacology and Nutritional Sciences

Sepsis is a leading cause of death in children. Glucocorticoid (GC) therapy had been strongly recommended for the pediatric sepsis (grade 1A). However, the recommendation was changed to grade 2C in 2020 due to weak evidence. Relative adrenal insufficiency (RAI) is a condition characterized by impaired inducible glucocorticoid (iGC) production in response to stress. It develops in 32.8% of pediatric septic patients. Unfortunately, little is known about the pathogenesis of RAI in pediatric sepsis, and whether GC therapy should be based on the status of RAI is controversial. In this study, we utilized 21-day-old SF1CreSRBI^fl/fl mice as the first …

Vitamin D Enhanced Vitamin D Receptor (Vdr) Inhibition Of Nlrp3 Inflammasome Activation Can Attenuate The Development Of Autoimmune Thyroiditis, Alexzon Mandac

Capstone Showcase

Autoimmune Thyroiditis (AIT) is a prevalent autoimmune disease affecting approximately 2% of the population. Characterized by the gradual loss of thyroid function through an autoimmune attack on the thyroid gland, the disease manifests symptoms that negatively affect one’s quality of life. The mechanisms behind the disease’s pathophysiology are not fully understood; however, researchers are examining the involvement of the NLRP3 inflammasome in the disease. This thesis will address the question of whether Vitamin D can act as an inhibitor of the NLRP3 inflammasome and attenuate the progression of AIT in mouse model. Current investigations explore the effects of NLRP3 inhibition …

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

Undergraduate Research Posters

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Alveolar Macrophages In Lung Cancer: Opportunities Challenges, Cheng-Yen Chang, Dominique Armstrong, David B Corry, Farrah Kheradmand

Faculty, Staff and Students Publications

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose foreign particles, defend the host against pathogens, recycle surfactant, and promptly respond to inhaled noxious stimuli. The behavior of AMs is tightly dependent on the environmental cues whereby infection, chronic inflammation, and associated metabolic changes can repolarize their effector functions in the lungs. Several factors within the tumor microenvironment can re-educate AMs, resulting in tumor growth, and reducing immune checkpoint inhibitors (ICIs) efficacy in patients treated for non-small cell lung cancer …

Covid-19 And Pregnancy: Clinical Outcomes; Mechanisms, And Vaccine Efficacy, Deepak Kumar, Sonam Verma, Indira U Mysorekar

Faculty, Staff and Students Publications

As the COVID-19 pandemic continues into its third year, emerging data indicates increased risks associated with SARS-CoV-2 infection during pregnancy, including pre-eclampsia, intrauterine growth restriction, preterm birth, stillbirth, and risk of developmental defects in neonates. Here, we review clinical reports to date that address different COVID-19 pregnancy complications. We also document placental pathologies induced by SARS-CoV-2 infection, entry mechanisms in placental cells, and immune responses at the maternal-fetal interface. Since new variants of SARS-CoV-2 are emerging with characteristics of higher transmissibility and more effective immune escape strategies, we also briefly highlight the genomic and proteomic features of SARS-CoV-2 investigated to …

The Effect Of An Educational Handout On Knowledge, Awareness And Attitudes Of Pre-Exposure Prophylaxis (Prep) Among Participants At A Needle And Syringe Exchange Site, Mckenzie Buckel

DNP Projects

Background: In 2018, the total number of HIV cases in the United States was 1.2 million. Almost 186,500 of these cases were attributed to intravenous drug use. With the adherence to pre-exposure prophylaxis (PrEP) there is approximately a 49% decrease in the rates of HIV among people who inject drugs and the most significant barrier to PrEP among this population is a lack of awareness and knowledge.

Objective: The purpose of this study was to determine participants’ of a needle and syringe exchange site knowledge, awareness and attitudes of PrEP after reviewing an educational handout about PrEP.

Methods: A quasi …

Effects Of Aging On Urinary Tract Epithelial Homeostasis And Immunity, Marianne M Ligon, Chetanchandra S Joshi, Bisiayo E Fashemi, Arnold M Salazar, Indira U Mysorekar

Faculty, Staff and Students Publications

A global increase in older individuals creates an increasing demand to understand numerous healthcare challenges related to aging. This population is subject to changes in tissue physiology and the immune response network. Older individuals are particularly susceptible to infectious diseases, with one of the most common being urinary tract infections (UTIs). Postmenopausal and older women have the highest risk of recurrent UTIs (rUTIs); however, why rUTIs become more frequent after menopause and during old age is incompletely understood. This increased susceptibility and severity among older individuals may involve functional changes to the immune system with age. Aging also has substantial …

Effective de-implementation models often include replacement of an ineffective practice with an alternative. We co-developed patient education materials as a replacement strategy for inappropriate post-procedural antibiotics in cardiac device procedures. Lessons learned and developed materials may be used to promote infection prevention in other periprocedural settings.

Glial Cell-Specific Contribution Of Pkr-Like Er Kinase (Perk) In Neuroinflammation And Behavior, Anirudhya Lahiri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neurological disorders such as multiple sclerosis (MS) are a major public health concern in the US, with no available therapeutic cure. Chronic neuroinflammation and aberrant proteostasis in the central nervous system (CNS) are the major hallmarks of neurological diseases. Endoplasmic Reticulum (ER) is a major cellular organelle involved in protein synthesis, folding and maturation of various secretory and transmembrane proteins. Pathophysiological stressors such as trauma and infection result in misfolded protein accumulation in the endoplasmic reticulum (ER) lumen, which results in ER stress. To regain proteostasis (protein homeostasis), cells activate the unfolded protein response (UPR). UPR is an evolutionarily conserved …

Orthodox Vs Paradox: The Roles Of Glycomics, Genetics And Beyond In Immunity, Immune Disorders And Glycomedicine, Wei Wang

Research outputs 2022 to 2026

The traditional ‘central dogma’ describes the flow of genetic information from DNA to RNA to protein. This process highlights the critical role of genes in living organisms. Nonetheless, ongoing immunological research coming to realize that emerging disciplines like glycomics and epigenetics are challenging the traditional viewpoint and extending the boundaries of the ‘central dogma’. . . .
