Do Paraben Derivatives Alter T Cell Immunity?, Hailey Kintz

Spring Presentation of Undergraduate Research

T cells immunity is linked to a complex system of cytokines that determine differentiation of naïve T cells into Th1, Th2, Th17, and Treg cells. Estrogen production or periods of elevated production have been correlated with an anti-inflammatory state in which Th2 and Treg cells are up-regulated. Such responses in the immune system are capable of supporting pre-cancerous activity. We are investigating the tie between the xenoestrogen compounds found in cosmetics, parabens, and their ability to regulate T cell immunity. Testing parabens and paraben derivatives with weaker estrogen receptor association will allow for a better understanding of the interplay between …

Analyzing The Differentiation Among State Medical Marijuana Policies By Examining State Policies & Trends, Richard Furlong

Political Science Theses and Capstones

Support for marijuana has been growing nationwide. This increased support has gained a lot of momentum since the late 1990s when California became the first state to legalize marijuana for medical use by enacting Proposition 215, or the Compassionate Use Act. Since the enactment of Proposition 215, 28 more states and the District of Columbia have legalized marijuana for medicinal use. I look into why states have begun to adopt these laws, and what makes these states differ throughout the country in the timeliness of their actions. I assembled data to examine a variety of state policies to attempt to …

Structure-Based Discovery Of Mpges-1 Inhibitors Suitable For Preclinical Testing In Wild-Type Mice As A New Generation Of Anti-Inflammatory Drugs, Kai Ding, Ziyuan Zhou, Shurong Hou, Yaxia Yuan, Shuo Zhou, Xirong Zheng, Jianzhong Chen, Charles D. Loftin, Fang Zheng, Chang-Guo Zhan

Molecular Modeling and Biopharmaceutical Center Faculty Publications

Human mPGES-1 is recognized as a promising target for next generation of anti-inflammatory drugs without the side effects of currently available anti-inflammatory drugs, and various inhibitors have been reported in the literature. However, none of the reported potent inhibitors of human mPGES-1 has shown to be also a potent inhibitor of mouse or rat mPGES-1, which prevents using the well-established mouse/rat models of inflammation-related diseases for preclinical studies. Hence, despite of extensive efforts to design and discover various human mPGES-1 inhibitors, the promise of mPGES-1 as a target for the next generation of anti-inflammatory drugs has never been demonstrated in …

Aging Exacerbates Development Of Cerebral Microbleeds In A Mouse Model, Rachita K. Sumbria, Mher Mahoney Grigoryan, Vitaly Vasilevko, Annlia Paganini-Hill, Kelley Kilday, Ronald Kim, David H. Cribbs, Mark J. Fisher

Pharmacy Faculty Articles and Research

Background: Cerebral microhemorrhages (CMH) are commonly found in the aging brain. CMH are also the neuropathological substrate of cerebral microbleeds (CMB), demonstrated on brain MRI. Recent studies demonstrate the importance of systemic inflammation in CMH development, but the relationships among inflammation, aging, and CMH development are not well-defined. In the current study, we hypothesized that the pathogenesis of inflammation-induced CMH in mice differs by age.

Methods: We studied young (3 months, n = 20) and old (18 months, n = 25) C57BL/6 mice injected with low-dose lipopolysaccharide (LPS; 1 mg/kg, i.p.) or saline at 0, 6, and 24 …

The Role Of Human Dopamine Transporter In Neuroaids, Jun Zhu, Subramaniam Ananthan, Chang-Guo Zhan

Molecular Modeling and Biopharmaceutical Center Faculty Publications

HIV-associated neurocognitive disorder (HAND) remains highly prevalent in HIV infected individuals and represents a special group of neuropathological disorders, which are associated with HIV-1 viral proteins, such as transactivator of transcription (Tat) protein. Cocaine abuse increases the incidence of HAND and exacerbates its severity by enhancing viral replication. Perturbation of dopaminergic transmission has been implicated as a risk factor of HAND. The presynaptic dopamine (DA) transporter (DAT) is essential for DA homeostasis and dopaminergic modulation of the brain function including cognition. Tat and cocaine synergistically elevate synaptic DA levels by acting directly on human DAT (hDAT), ultimately leading to dysregulation …

Relationship Between The Dimerization Of Thyroglobulin And Its Ability To Form Triiodothyronine, Cintia E. Citterio, Yoshiaki Morishita, Nada Dakka, Balaji Veluswamy, Peter Arvan

Pharmacy Faculty Articles and Research

Thyroglobulin (TG) is the most abundant thyroid gland protein, a dimeric iodoglycoprotein (660 kDa). TG serves as the protein precursor in the synthesis of thyroid hormones tetraiodothyronine (T₄) and triiodothyronine (T₃). The primary site for T₃ synthesis in TG involves an iodotyrosine acceptor at the antepenultimate Tyr residue (at the extreme carboxyl terminus of the protein). The carboxyl-terminal region of TG comprises a cholinesterase-like (ChEL) domain followed by a short unique tail sequence. Despite many studies, the monoiodotyrosine donor residue needed for the coupling reaction to create T₃ at this evolutionarily conserved …

The Winding Road To Relapse: Forging A New Understanding Of Cue-Induced Reinstatement Models And Their Associated Neural Mechanisms, Mark D. Namba, Seven E. Tomek, M. Foster Olive, Joshua S. Beckmann, Cassandra D. Gipson

Psychology Faculty Publications

In drug addiction, cues previously associated with drug use can produce craving and frequently trigger the resumption of drug taking in individuals vulnerable to relapse. Environmental stimuli associated with drugs or natural reinforcers can become reliably conditioned to increase behavior that was previously reinforced. In preclinical models of addiction, these cues enhance both drug self-administration and reinstatement of drug seeking. In this review, we will dissociate the roles of conditioned stimuli as reinforcers from their modulatory or discriminative functions in producing drug-seeking behavior. As well, we will examine possible differences in neurobiological encoding underlying these functional differences. Specifically, we will …

Pharmacy Faculty Articles and Research

In this studies, three fatty acyl derivatives of CGKRK homing peptides were coupled successfully to chitosan oligosaccharides (COS) using sulfosuccinimidyl-4-(N-maleimidomethyl)cyclohexane-1-carboxylate sodium salt (sulfo-SMCC). The COS-SMCC was prepared by direct coupling between COS and sulfo-SMCC in PBS (pH 7.5) at RT for 48 h. The structure of COS-SMCC and the three fatty acyl-CGKRK-SMCC-COS conjugates were characterized by FT-IR, ¹³C NMR, and SEM. The ability of three conjugates to condense siRNA into nanosized polyplexes and their efficacy in protecting siRNA from serum nucleases degradation were investigated. Among the investigated derivatives, S-CGKRK-COS showed higher siRNA binding affinity as compared to …

Twenty-four hours after scar formation, cornea received topically either balanced salt solution (BSS; n ¼ 6), polyethylenimine-conjugated gold nanoparticle (PEI2-GNP)-naked plasmid (n ¼ 6) or PEI2-GNP plasmids expressing BMP7 and HGF genes (n ¼ 6). Donor human corneas were used to obtain primary human corneal fibroblasts and myofibroblasts for mechanistic studies. …

Bacterial Lps At The Immune Modulating Component In Juzen-Taiho-To, Diego Montenegro

Dissertations, Theses, and Capstone Projects

Juzen-taiho-to (JTT) is an immune-boosting herbal formulation with an ideal balance of safety and efficacy. For example, JTT is clinically used in Japan to stimulate the immunological functions of cancer patients undergoing chemotherapy and radiation. Although the clinical effects of JTT are recognized, the active compounds and mechanism of action are unknown. The studies conducted previously in our laboratory associated several phytosterols and plant glycolipids with the potent immunostimulatory activity of JTT: namely, β-sitosteryl β-D-glucoside (BSSG), glucocerebroside (GluCer), digalactosyldiacylglycerol (DGDG) and monogalactosyldiacylglycerol (MGDG). However, these compounds, when further purified, exhibited little or no immunostimulatory activity. This suggested that the immunostimulatory …

Regulation Of Kv2.1 Channel Inactivation By Phosphatidylinositol 4,5-Bisphosphate., Mayra Delgado-Ramírez, José J De Jesús-Pérez, Iván A Aréchiga-Figueroa, Jorge Arreola, Scott K Adney, Carlos A. Villalba-Galea, Diomedes E Logothetis, Aldo A Rodríguez-Menchaca

School of Pharmacy Faculty Articles

Phosphatidylinositol 4,5-bisphosphate (PIP2) is a membrane phospholipid that regulates the function of multiple ion channels, including some members of the voltage-gated potassium (Kv) channel superfamily. The PIP2 sensitivity of Kv channels is well established for all five members of the Kv7 family and for Kv1.2 channels; however, regulation of other Kv channels by PIP2 remains unclear. Here, we investigate the effects of PIP2 on Kv2.1 channels by applying exogenous PIP2 to the cytoplasmic face of excised membrane patches, activating muscarinic receptors (M1R), or depleting endogenous PIP2 using a rapamycin-translocated 5-phosphatase (FKBP-Inp54p). Exogenous PIP2 rescued Kv2.1 channels from rundown and partially …

Trends And Economic Drivers For United States Naloxone Pricing, January T 2006 To February 2017, Matthew Rosenberg, Grace Chai, Shekhar Mehta, Andreas Schick

United States Food and Drug Administration: Publications

Anecdotal evidence indicates that naloxone prices have risen in recent years, but limited research has examined the magnitude of these increases and potential causes. We contribute nationally representative evidence to help answer each of these questions, including wholesale pricing data from a proprietary drug sales database span- ning January 2006 to February 2017. We find that all formulations of naloxone increased in price since 2006 except for Narcan Nasal Spray. These cumulative increases totaled 2281% for the 0.4 MG single-dose products, 244% for the 2 MG single-dose products, 3797% for the 4 MG multi-dose products, and 469% for the 0.4 …

Clearance Concepts: Fundamentals And Application To Pharmacokinetic Behavior Of Drugs, Reza Mehvar

Pharmacy Faculty Articles and Research

Clearance concepts were introduced into the pharmacokinetics discipline in the 1970s and since then have played a major role in characterization of the pharmacokinetic behavior of drugs. These concepts are based on the relationship between organ extraction ratio or clearance and physiologic parameters such as the organ blood flow and the intrinsic capability of the eliminating organ to remove the free (unbound) drug from the body. Several theoretical models have been developed, which define these relationships and may be used to predict the effects of changes in the physiological parameters on various pharmacokinetic parameters of drugs, such as drug clearance. …

Galantamine's Deconstruction In The Quest Of A Pam Pharmacophore, Malaika Argade

Theses and Dissertations

Alzheimer’s disease is a progressive neurodegenerative disorder generally affecting people above the age of 65 years. Even though the pathophysiological hallmarks of AD were established more than a hundred years ago, there is yet to be a drug that can stop its characteristic neuronal damage. Of the five currently FDA-approved drugs, galantamine has a unique mechanism of action. Apart from being an AChE inhibitor, galantamine can effectively potentiate (positive allosteric modulator) the effect of agonists at nAChRs at concentrations lower than those required for its action as an AChE inhibitor. Perhaps the clinical benefits observed with galantamine are associated mainly …

Implementing A Public Health Perspective In Fda Drug Regulation, Patricia J. Zettler, Margaret Foster Riley, Aaron S. Kesselheim

Faculty Publications By Year

There is, without question, a public health crisis in the United States arising from both illicit and prescription opioid misuse, addiction, and overdose. The Food and Drug Administration (FDA) is one regulator with an important role to play in minimizing the harms associated with prescription opioids, while also ensuring that prescription opioids are available for the evidence-based management of pain. One question, however, is to what extent the agency can consider in its decisions to approve opioids and keep existing ones on the market the provider and patient behaviors contributing to the epidemic. This is, in part, because FDA’s approval …

Communicating Nutrition Information At The Point Of Purchase: An Eye‐Tracking Study Of Shoppers At Two Grocery Stores In The United States, Mike Bartels, Katherin Tillack, Chung‐Tung Jordan Lin

United States Food and Drug Administration: Publications

Providing nutrition information at the point of purchase is one approach that can be used to help consumers adopt and maintain a healthy diet. Previous research has examined consumer self‐reported notice and use of the information as well as how the design of the information affects its attention and use in a laboratory environ‐ ment using eye‐tracking methodology. This study advances the literature by applying eye‐tracking methodology to explore consumer visual and choice behavior in a real shopping environment, and by recognizing that nutrition information competes with other visual stimuli in the store and consumers are vulnerable to a “limited …

Development And Preclinical Evaluation Of Long-Lasting Cocaine Hydrolases For Cocaine Overdose And Cocaine Use Disorder Treatment, Ting Zhang

Theses and Dissertations--Pharmacy

Cocaine is a plant-based illicit drug commonly involved in substance use disorder. Although cocaine overdose and cocaine use disorders cause adverse health consequences to individuals and the economic burden on their family and society, there are no FDA (Food and Drug Administration) approved medications for treatment. Recently, it has been recognized that delivery of cocaine hydrolase (CocH) is a promising therapeutic strategy. Human butyrylcholinesterase (hBChE), the primary enzyme involved in cocaine metabolism in human, have advantages over other candidates for the development of CocH. Previous studies in our laboratory have designed and characterized hBChE mutants that have ~4,000-fold improved catalytic …

The Development Of Microfluidic Devices For The Production Of Safe And Effective Non-Viral Gene Delivery Vectors, Jason Matthew Absher

Theses and Dissertations--Chemical and Materials Engineering

Including inherited genetic diseases, like lipoprotein lipase deficiency, and acquired diseases, such as cancer and HIV, gene therapy has the potential to treat or cure afflicted people by driving an affected cell to produce a therapeutic protein. Using primarily viral vectors, gene therapies are involved in a number of ongoing clinical trials and have already been approved by multiple international regulatory drug administrations for several diseases. However, viral vectors suffer from serious disadvantages including poor transduction of many cell types, immunogenicity, direct tissue toxicity and lack of targetability. Non-viral polymeric gene delivery vectors (polyplexes) provide an alternative solution but are …
