Tuberculosis (TB) is currently one of the leading causes of global mortality. Medical non-compliance due to the length of the treatment and antibiotic side effects has led to the emergence of multidrug-resistant (MDR) strains of Mycobacterium tuberculosis (M. tb) that are difficult to treat. A current therapeutic strategy attempting to circumvent this issue aims to enhance drug delivery to reduce the duration of the antibiotic regimen or dosage of first-line antibiotics. One such agent that may help is cyclic peptide [R4W4], as it has been shown to have antibacterial properties (in combination with tetracycline) …
Ctrp3 And Alcoholic Liver Disease In Female Mice, Callie Root
Ctrp3 And Alcoholic Liver Disease In Female Mice, Callie Root
Undergraduate Honors Theses
C1q TNF Related Protein 3 (CTRP3), is a cytokine that is primarily secreted from adipose tissue, which classifies it as an adipokine. Our previous research has shown that CTRP3 prevents alcoholic fatty liver disease (ALD) in male mice. However, even when accounting for confounding factors such as absolute and relative alcohol intake, females are more sensitive to the effects of consumption compared to male mice. Therefore, the goal of this project was to determine whether CTRP3 prevented ALD in female mice. Methods: Female wild type (WT) and female CTRP3 transgenic over expressing (Tg) mice were fed an ethanol containing liquid …
Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra
Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra
The Summer Undergraduate Research Fellowship (SURF) Symposium
Microglia are the brain’s resident immune cells that are responsible for maintaining homeostasis in healthy conditions. During injury or infection, resting microglia get activated and produce pro-inflammatory cytokines such as IL-1b, IL-1a, IL-6, etc. along with reactive oxygen species like nitric oxide (NO) to combat neuroinflammatory diseases such as Alzheimer’s disease (AD). Inflammation is characterized by the activation of resident-immune cells in the brain called microglia that respond to the eat-me signals released by the toxic amyloid beta peptides as well as the dying neurons in the microenvironment. Recent studies have shown that activated microglia induce neuronal death by secreting …
Better Cognitive Control Of Emotional Information Is Associated With Reduced Pro-Inflammatory Cytokine Reactivity To Emotional Stress, Grant S. Shields, Shari Young Kuchenbecker, Sarah D. Pressman, Ken D. Sumida, George M. Slavich
Better Cognitive Control Of Emotional Information Is Associated With Reduced Pro-Inflammatory Cytokine Reactivity To Emotional Stress, Grant S. Shields, Shari Young Kuchenbecker, Sarah D. Pressman, Ken D. Sumida, George M. Slavich

Stress is strongly associated with several mental and physical health problems that involve inflammation, including asthma, cardiovascular disease, certain types of cancer, and depression. It has been hypothesized that better cognitive control of emotional information may lead to reduced inflammatory reactivity to stress and thus better health, but to date no studies have examined whether differences in cognitive control predict pro-inflammatory cytokine responses to stress. To address this issue, we conducted a laboratory-based experimental study in which we randomly assigned healthy young-adult females to either an acute emotional stress (emotionally evocative video) or no-stress (control video) condition. Salivary levels of …
Pegylated Interferon Α-2b Up-Regulates Specific Cd8+ T Cells In Patients With Chronic Hepatitis B, Ji Chen, Yan Wang, Jun Li, Feng-Qin Hou, Gui-Qiang Wang
Pegylated Interferon Α-2b Up-Regulates Specific Cd8+ T Cells In Patients With Chronic Hepatitis B, Ji Chen, Yan Wang, Jun Li, Feng-Qin Hou, Gui-Qiang Wang
Pharmacology and Toxicology Faculty Publications
AIM: To investigate the effect of pegylated interferon (IFN) α-2b on specific CD8+ T lymphocytes in patients with chronic hepatitis B (CHB). METHODS: Twenty-one patients with CHB were treated with pegylated IFN α-2b. Periphery blood mononuclear cells were isolated from fresh heparinized blood by Ficoll-Hypaque density gradient centrifugation (density: 1.077 g/L, Pharmingen) at weeks 0, 4, 8, 12, and 24, respectively. Frequency of circulating hepatitis B virus (HBV) epitope-specific CD8 T cells was detected by flow cytometry. Cytokines were detected by cytometric bead assay. RESULTS: The frequency of circulating HBV core or env-specific CD8 T cells was higher (P …
Hepatoma Cells Up-Regulate Expression Of Programmed Cell Death-1 On T Cells, Ji Chen, Gui-Qiang Wang
Hepatoma Cells Up-Regulate Expression Of Programmed Cell Death-1 On T Cells, Ji Chen, Gui-Qiang Wang
Pharmacology and Toxicology Faculty Publications
AIM: To investigate the effect of hepatoma cells on up-regulation of programmed cell death-1 (PD-1), and the function of PD-1 on T cells. METHODS: HepG2 or HepG2.2.1.5 cells were co-cultured with a lymphoma cell line-Jurkat cells. PD-1 expression was detected by flow cytometry. IL-2, INF-γ and IL-10 in culture supernatant were detected by enzyme-linked immunosorbent assay (ELISA). Cytotoxic action of T cells was determined by MTT reduction assay-direct mononuclear cell cytotoxicity assay. RESULTS: The PD-1 expression on Jurkat cells increased by 16.17% ± 2.5% and 17.43% ± 2.2% after HepG2 or HepG2.2.1.5 cells were co-cultured for 48 h. The levels …
