Nucleoside reverse transcriptase inhibitors (NRTIs) are mainstay therapeutics for HIV that block retrovirus replication. Alu (an endogenous retroelement that also requires reverse transcriptase for its life cycle)–derived RNAs activate P2X7 and the NLRP3 inflammasome to cause cell death of the retinal pigment epithelium in geographic atrophy, a type of age-related macular degeneration. We found that NRTIs inhibit P2X7-mediated NLRP3 inflammasome activation independent of reverse transcriptase inhibition. Multiple approved and clinically relevant NRTIs prevented caspase-1 activation, the effector of the NLRP3 inflammasome, induced by Alu RNA. NRTIs were efficacious in mouse models of geographic atrophy, choroidal neovascularization, graft-versus-host disease, and sterile …

Effects Of Pde4 Pathway Inhibition In Rat Experimental Stroke, Fan Yang, Rachita K. Sumbria, Dong Xue, Chuanhui Yu, Dan He, Shuo Liu, Annlia Paganini-Hill, Mark J. Fisher

Pharmacy Faculty Articles and Research

PURPOSE: The first genomewide association study indicated that variations in the phosphodiesterase 4D (PDE4D) gene confer risk for ischemic stroke. However, inconsistencies among the studies designed to replicate the findings indicated the need for further investigation to elucidate the role of the PDE4 pathway in stroke pathogenesis. Hence, we studied the effect of global inhibition of the PDE4 pathway in two rat experimental stroke models, using the PDE4 inhibitor rolipram. Further, the specific role of the PDE4D isoform in ischemic stroke pathogenesis was studied using PDE4D knockout rats in experimental stroke. METHODS: Rats were subjected to either the …

Vaccine-Preventable Diseases In Travelers, Edith Mirzaian, Jeffery A. Goad, Ani Amloian, Fady Makar

Travel to the developing world is increasing among those from developed countries, placing them at risk for vaccine preventable and non-vaccine preventable diseases. From 2007-2011, the GeoSentinel Network reported 737 returned travelers with a vaccine preventable disease. While it is essential that clinicians use vaccines when available for a disease of risk, they should also be aware that the vast majority of diseases acquired by travelers are non-vaccine preventable. The vaccine preventable diseases can be divided into routine travel vaccines, special travel vaccines and routine vaccines used for travel. The routine travel vaccines include Hepatitis A and B, typhoid; special …

This home-study CPE activity has been developed to educate pharmacists on the common drug-drug and food-drug interactions associated with cardiovascular medications.

Simultaneous Bactericidal And Osteogenic Effect Of Nanoparticulate Calcium Phosphate Powders Loaded With Clindamycin On Osteoblasts Infected With Staphylococcus Aureus, Vuk Uskoković, Tejal A. Dasai

Pharmacy Faculty Articles and Research

S aureus internalized by bone cells and shielded from the immune system provides a reservoir of bacteria in recurring osteomyelitis. Its targeting by the antibiotic therapy may thus be more relevant for treating chronic bone infection than eliminating only the pathogens colonizing the bone matrix. Assessed was the combined osteogenic and antibacterial effect of clindamycinloaded calcium phosphate nanoparticles of different monophasic compositions on co-cultures comprising osteoblasts infected with S aureus. Antibiotic-carrying particles were internalized by osteoblasts and minimized the concentration of intracellular bacteria. In vitro treatments of the infected cells, however, could not prevent cell necrosis due to the …

Nanoparticulate Drug Delivery Platforms For Advancing Bone Infection Therapies, Vuk Uskoković, Tejal A. Dasai

Pharmacy Faculty Articles and Research

Introduction—The ongoing surge of resistance of bacterial pathogens to antibiotic therapies and the consistently aging median member of the human race signal an impending increase in the incidence of chronic bone infection. Nanotechnological platforms for local and sustained delivery of therapeutics hold the greatest potential for providing minimally invasive and maximally regenerative therapies for this rare but persistent condition.

Areas covered—Shortcomings of the clinically available treatment options, including poly(methyl methacrylate) beads and calcium sulfate cements, are discussed and their transcending using calcium-phosphate/polymeric nanoparticulate composites is foreseen. Bone is a composite wherein the weakness of each component alone is …

Cxcr7 Expression Disrupts Endothelial Cell Homeostasis And Causes Ligand-Dependent Invasion, Jennifer Totonchy, Lisa Clepper, Kevin G. Phillips, Owen J. T. Mccarty, Ashlee V. Moses

Pharmacy Faculty Articles and Research

The homeostatic function of endothelial cells (EC ) is critical for a number of physiological processes including vascular integrity, immunity, and wound healing. Indeed, vascular abnormalities resulting from EC dysfunction contribute to the development and spread of malignancies. The alternative SDF-1/CXCL12 receptor CXCR7 is frequently and specifically highly expressed in tumor-associated vessels. In this study, we investigate whether CXCR7 contributes to vascular dysfunction by specifically examining the effect of CXCR7 expression on EC barrier function and motility. We demonstrate that CXCR7 expression in EC results in redistribution of CD31/PECAM-1 and loss of contact inhibition. Moreover, CXCR7+ EC are deficient in …

Implementation Of A Pharmacy-Based Adult Vaccine Benefit: Recommendations For A Commercial Health Plan Benefit, Jeffery A. Goad, Kelly J. Ko, Rolin L. Wade, Hsing-Ting Yu, Ross M. Miller, Bruce Sherman

Pharmacy Faculty Articles and Research

BACKGROUND: Although vaccination rates in children exceed 90% in the United States, adults are vaccinated at far lower rates. In order to address this issue, additional community immunizers are needed, and pharmacists are in an ideal position to fill this void.

OBJECTIVES: To explore issues and barriers related to implementation of a pharmacy-based adult vaccine benefit and develop recommendations supporting a pathway for benefit expansion.

METHODS: A literature review on the current environment surrounding pharmacy-based adult vaccinations and structured interviews were conducted to inform an expert panel meeting using a modified Delphi process (pre/post survey). The goal …
