The genetic diversity among globally circulating human immunodeficiency virus type 1 (HIV-1) strains is a serious challenge for HIV-1 vaccine design. We have generated a synthetic groupMconsensus env gene (CON6) for induction of cross-subtype immune responses and report here a comparative study of T-cell responses to this and natural strain env immunogens in a murine model. Three different strains of mice were immunized with CON6 as well as subtype A, B, or C env immunogens, using a DNA prime-recombinant vaccinia virus boost strategy. T-cell epitopes were mapped by gamma interferon enzyme-linked immunospot analysis using five overlapping Env peptide sets from …

Hypertension And Kidney Disease In Asia, Tazeen H. Jafar

Section of Nephrology

PURPOSE OF REVIEW: Communicable diseases were traditionally the major cause of public health concern in Asian countries, most of which were less developed. With industrialization and associated lifestyle changes during the past few decades, however, noncommunicable diseases similar to those that affect Western societies have emerged in Asian countries. The purpose of the review was to examine recent evidence about the burden and factors associated with hypertension and chronic kidney disease (CKD) in Asian countries.RECENT FINDINGS: Hypertension has become one of the leading causes of mortality in Asia. Although its prevalence continues to rise, it remains under-diagnosed and under-treated. CKD …

Staphylococcus Aureus Escapes More Efficiently From The Phagosome Of A Cystic Fibrosis Bronchial Epithelial Cell Line Than From Its Normal Counterpart, Todd M. Jarry, Ambrose L. Cheung

Dartmouth Scholarship

Staphylococcus aureus is frequently the initial bacterium isolated from young cystic fibrosis (CF) patients, and yet its role in CF disease progression has not been determined. Recent data from our lab demonstrates that S. aureus can invade and replicate within the CF tracheal epithelial cell line (CFT-1). Here we describe the finding that the fate of internalized S. aureus in CFT-1 cells differs from its complemented counterpart (LCFSN). S. aureus strain RN6390 was able to replicate within the mutant CFT-1 cells after invasion but not in the complemented LCFSN cells. At 1 h postinvasion, S. aureus containing vesicles within both …

Immunization Update, Karl M. Hess, Jeffery A. Goad

Pharmacy Faculty Articles and Research

"Immunization represents a very effective primary prevention strategy to curb the rate of vaccine preventable diseases...Pharmacists can play a leading role in vaccination by serving as an advocate, facilitator, and active immunizer. As an advocate, pharmacists provide vaccine education while motivating people to get immunized. As a facilitator, pharmacy’s can host other groups, such as the visiting nurses association, to come into the pharmacy and vaccinate. As an active immunizer, however, pharmacists serve their greatest role by giving immunizations to adolescents and adults."

Comparison Of Og1rf And An Isogenic Fsrb Deletion Mutant By Transcriptional Analysis: The Fsr System Of Enterococcus Faecalis Is More Than The Activator Of Gelatinase And Serine Protease, Agathe Bourgogne, Susan G Hilsenbeck, Gary M Dunny, Barbara E Murray

Faculty, Staff and Student Publications

The FsrABC system of Enterococcus faecalis controls the expression of gelatinase and a serine protease via a quorum-sensing mechanism, and recent studies suggest that the Fsr system may also regulate other genes important for virulence. To investigate the possibility that Fsr influences the expression of additional genes, we used transcriptional profiling, with microarrays based on the E. faecalis strain V583 sequence, to compare the E. faecalis strain OG1RF with its isogenic mutant, TX5266, an fsrB deletion mutant. We found that the presence of an intact fsrB influences expression of numerous genes throughout the growth phases tested, namely, late log to …

Investigation Of Cell Surface Phenotypes At Mucosal Sites In Response To Murine Cytomegalovirus Infection, Mary Esther Bruorton

MUSC Theses and Dissertations

The salivary gland is the predominant effector site of mucosal immune responses in the oral cavity. In mice, the salivary glands are known to receive immune lymphocytes stimulated in inductive sites such as the gut- and nasal-associated lymphoid tissues, thus, allowing the production of antigen-specific antibodies in saliva. However, the potential of the salivary gland as a mucosal inductive site has not been fully explored. In order to investigate this concept, we have developed a model resulting in a focused salivary gland infection using intraglandular delivery of tissue culture-derived murine cytomegalovirus (tcMCMV). Utilizing this route of infection, we were capable …

HIV-1 subtype C is the most common HIV-1 group M subtype in Africa and many parts of Asia. However, to date HIV-1 vaccine candidate immunogens have not induced potent and broadly neutralizing antibodies against subtype C primary isolates. We have used a centralized gene strategy to address HIV-1 diversity, and generated a group M consensus envelope gene with shortened consensus variable loops (CON-S) for comparative studies with wildtype (WT) Env immunogens. Our results indicate that the consensus HIV-1 group M CON-S Env elicited cross-subtype neutralizing antibodies of similar or greater breadth and titer than the WT Envs tested, indicating the …

Innate Antiviral Response Targets Hiv-1 Release By The Induction Of Ubiquitin-Like Protein Isg15, Atsushi Okumura, Gengshi Lu, Ian Pitha-Rowe, Paula M. Pitha

Dartmouth Scholarship

The goal of this study was to elucidate the molecular mechanism by which type I IFN inhibits assembly and release of HIV-1 virions. Our study revealed that the IFN-induced ubiquitin-like protein ISG15 mimics the IFN effect and inhibits release of HIV-1 virions without having any effect on the synthesis of HIV-1 proteins in the cells. ISG15 expression specifically inhibited ubiquitination of Gag and Tsg101 and disrupted the interaction of the Gag L domain with Tsg101, but conjugation of ISG15 to Gag or Tsg101 was not detected. The inhibition of Gag-Tsg101 interaction was also detected in HIV-1 infected, IFN-treated cells. Elimination …

Relationship Between Antipyretic Effects And Cytokine Levels In Uncomplicated Falciparum Malaria During Different Treatment Regimes, Elisabeth Hugosson, Scott M. Montgomery, Zul Premji, Marita Troye-Blomberg, Anders Bjorkman

Pathology, East Africa

We have previously shown that both chloroquine and paracetamol (acetaminophen) have antipyretic activity during treatment of acute uncomplicated Plasmodium falciparum malaria in children 1-4 years old. Here, we studied if this effect was accompanied by changes in plasma cytokine levels. The 104 children were treated with either chloroquine or sulfadoxine/pyrimethamine (SP) alone, SP + chloroquine or SP + paracetamol for 4 days. Cytokine levels were determined days 0, 2 and 3, body temperature every sixth hour until 72 h and parasitemia once daily for 4 days. At admission, body temperature correlated with levels of IL-10, IFN-γ and IL-6, and parasitemia …

INTRODUCTION: Epstein-Barr virus (EBV) is present in over 90% of the world's population. This infection is considered benign, even though in limited cases EBV is associated with infectious and neoplastic conditions. Over the past decade, the EBV association with breast cancer has been constantly debated. Adding to this clinical and biological uncertainty, different techniques gave contradictory results for the presence of EBV in breast carcinoma specimens. In this study, minor groove binding (MGB)-TaqMan real time PCR was used to detect the presence of EBV DNA in both peripheral blood and tumor samples of selected patients. METHODS: Peripheral blood and breast …

Construction Of Improved Temperature-Sensitive And Mobilizable Vectors And Their Use For Constructing Mutations In The Adhesin-Encoding Acm Gene Of Poorly Transformable Clinical Enterococcus Faecium Strains, Sreedhar R Nallapareddy, Kavindra V Singh, Barbara E Murray

Faculty, Staff and Student Publications

Inactivation by allelic exchange in clinical isolates of the emerging nosocomial pathogen Enterococcus faecium has been hindered by lack of efficient tools, and, in this study, transformation of clinical isolates was found to be particularly problematic. For this reason, a vector for allelic replacement (pTEX5500ts) was constructed that includes (i) the pWV01-based gram-positive repAts replication region, which is known to confer a high degree of temperature intolerance, (ii) Escherichia coli oriR from pUC18, (iii) two extended multiple-cloning sites located upstream and downstream of one of the marker genes for efficient cloning of flanking regions for double-crossover mutagenesis, (iv) transcriptional terminator …

Antiviral Agents For Pregnant Women With Genital Herpes, Christopher Wenner Md

Articles

Clinical Question

Do antiviral medications prevent perinatal transmission of genital herpes to neonates?

Evidence-Based Answer

There is no evidence that the use of antiviral agents in women who are pregnant and have a history of genital herpes prevents perinatal transmission of herpes simplex virus (HSV) to neonates. [Strength of recommendation: A, based on multiple systematic reviews] However, treatment with antivirals during the last month of pregnancy does reduce the rate of HSV outbreaks in pregnant women and the resultant need for cesarean delivery. [Strength of recommendation: A, based on multiple systematic reviews]
