Treatment Of Spinal Tuberculosis: Role Of Surgical Intervention, Ather Enam, Ahmed Ali Shah
Treatment Of Spinal Tuberculosis: Role Of Surgical Intervention, Ather Enam, Ahmed Ali Shah
Section of Neurosurgery
The treatment of tuberculosis of the spine (Pott's disease) is essentially conservative and a vast majority of patients can be successfully managed on antituberculo us therapy (ATT) alone.1 Surgery is indicated in a few specific cases where deformity of spine, pain, or neurological compromise is becoming a serious issue. In cases where surgery is indicated the benefits are almost immediate and excellent. Tuberculosis (TB) is one of the leading causes of infectious disease-related deaths in under-developed countries and it has had a resurgence in developed countries as well. The most common site of bony dissemination of this disease is in …

Toxin-coregulated pilin A (TcpA) is the main structural subunit of a type IV bundle-forming pilus of Vibrio cholerae, the cause of cholera. Toxin-coregulated pilus is involved in formation of microcolonies of V. cholerae at the intestinal surface, and strains of V. cholerae deficient in TcpA are attenuated and unable to colonize intestinal surfaces. Anti-TcpA immunity is common in humans recovering from cholera in Bangladesh, and immunization against TcpA is protective in murine V. cholerae models. To evaluate whether transcutaneously applied TcpA is immunogenic, we transcutaneously immunized mice with 100 mug of TcpA or TcpA with an immunoadjuvant (cholera toxin [CT], …

The neutralizing antibody response to the protective antigen (PA) component of anthrax toxin elicited by approved anthrax vaccines is an accepted correlate for vaccine-mediated protection against anthrax. We reasoned that a human anti-PA monoclonal antibody (MAb) selected on the basis of superior toxin neutralization activity might provide potent protection against anthrax. The fully human MAb (also referred to as MDX-1303 or Valortim) was chosen from a large panel of anti-PA human MAbs generated using transgenic mice immunized with recombinant PA solely on the basis of in vitro anthrax toxin neutralization. This MAb was effective in prophylactic and postsymptomatic treatment of …

Dartmouth Scholarship
The interactions between CD80 and CD86 on antigen-presenting cells and CD28 on T cells serve as an important costimulatory signal in the activation of T cells. Although the simplistic two-signal hypothesis has been challenged in recent years by the identification of different costimulators, this classical pathway has been shown to significantly impact antiviral humoral and cellular immune responses. How the CD80/CD86-CD28 pathway affects the control of chronic or latent infections has been less well characterized. In this study, we investigated its role in antiviral immune responses against murine gammaherpesvirus 68 (MHV-68) and immune surveillance using CD80/CD86−/− mice. In the …

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 …

Five cases of Lassa fever have been imported from West Africa to the United States since 1969. We report symptoms of the patient with the second imported case and the symptoms and long-term follow-up on the patient with the third case. Vertigo in this patient has persisted for 30 years.
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
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 …

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

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 …
