Enhancement of Antibodies to the Human Immunodeficiency Virus Type 1 Envelope by Using the Molecular Adjuvant C3d
(East Carolina University, 2003-02)
DNA vaccines expressing the envelope (Env) protein of the human immunodeficiency virus have been relatively ineffective at generating high-titer, long-lasting, neutralizing antibodies in a variety of animal models. In this ...
Functions Required for Extracellular Quinolone Signaling by Pseudomonas aeruginosa
(East Carolina University, 2002-12)
A set of 30 mutants exhibiting reduced production of the phenazine poison pyocyanin were isolated following transposon mutagenesis of Pseudomonas aeruginosa PAO1. The mutants could be subdivided into those with defects in ...
Transcriptional Activation of Bordetella Alcaligin Siderophore Genes Requires the AlcR Regulator with Alcaligin as Inducer
(East Carolina University, 2001-01)
Genetic and biochemical studies have established that Fur and iron mediate repression of Bordetella alcaligin siderophore system (alc) genes under iron-replete nutritional growth conditions. In this study, transcriptional ...
Enhanced Avidity Maturation of Antibody to Human Immunodeficiency Virus Envelope: DNA Vaccination with gp120-C3d Fusion Proteins
(East Carolina University, 2001-06-10)
DNA vaccination can elicit both humoral and cellular immune responses and can confer protection against several pathogens. However, DNA vaccines expressing the envelope (Env) protein of human immunodeficiency virus (HIV) ...
RecA and RadA Proteins of Brucella abortus Do Not Perform Overlapping Protective DNA Repair Functions following Oxidative Burst
(East Carolina University, 2006-07)
Very little is known about the role of DNA repair networks in Brucella abortus and its role in pathogenesis. We investigated the roles of RecA protein, DNA repair, and SOS regulation in B. abortus. While recA mutants in ...
PI(4,5)P2 concentration at the APC side of the Immunological Synapse is Required for Effector T cell Function
(East Carolina University, 2009-05-01)
Little is known about the signaling that occurs in an antigen presenting cell (APC) during contact with a T cell. Here we report the concentration of the signaling lipid, PI(4,5)P2, at the APC side of the immunological ...
Targeting the RAF/MEK/ERK, PI3K/AKT and P53 pathways in hematopoietic drug resistance
(East Carolina University, 2007)
Raf-Induced Vascular Endothelial Growth Factor Augments Kaposi's Sarcoma-Associated Herpesvirus Infection
(East Carolina University, 2004-12)
Recombinant green fluorescent protein encoding Kaposi’s sarcoma-associated herpesvirus (rKSHV.152) infection of -estradiol stimulated human foreskin fibroblasts (HFF) or HFF/ B-Raf[FF]:ER (expressing a weaker form of ...
Generation and characterization of the humoral immune response to DNA immunization with a chimeric beta-amyloid-interleukin-4 minigene
(East Carolina University, 2003-12)
Active immunization with fibrillar beta-amyloid peptide (AB42) as well as passive transfer of anti-AB antibodies significantly reduces AB plaque deposition, neuritic dystrophy, and astrogliosis in the brain of mutant amyloid ...
Inhibition of Quorum Sensing by a Pseudomonas aeruginosa dksA Homologue
(East Carolina University, 2001-03)
The Pseudomonas aeruginosa las (lasR-lasI) and rhl (rhlR-rhlI) quorum-sensing systems regulate the expression of several virulence factors, including elastase and rhamnolipid. P. aeruginosa strain PR1-E4 is a lasR deletion ...
