Research ArticleOpen accessIn the abstractAnamnestic Immune Response Eight Years After Immunization of Primates with a Multivalent HIV-1 GP120 Variable Peptide VaccineRebecca Rivera, Kyung Hee Kang, David E. Anderson et al.Successful development of an effective HIV vaccine hasn’t occurred yet partly as a consequence of the antigenic variation deployed by HIV-1 to escape the immune system. Our laboratory is dedicated to develop a single peptide synthesis approach to create multivalent peptides representing hypervariable epitopes of the gp120 envelope glycoprotein of HIV-1. Our previous study showed that our HIV HECs are … …American Journal of Immunology, Vol. 9, Issue 1 · 13 Mar 2013 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractPorcine Respiratory and Reproductive Syndrome Virus Vaccinology: A Review for Commercial VaccinesV. G. PapatsirosPorcine Reproductive and Respiratory Syndrome (PRRS) since its appearance in Europe in the early 1990’s has resulted in tremendous economic losses. Under field conditions vaccination is one of the most efficient strategies for the prevention and control of PRRS. The aim of this study is to perform the PRRSV vaccinology regarding current status of commercial vaccines in Europe. There are … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 5 Nov 2012 · 8,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractHyper-Ag-specific Ab Production in NC/Nga Mice is not associated with Deletion Polymorphism in the Promotor Region of the FcγRIIB GeneTohru Sakai, Mariko Nakamoto, Emi SutoProblem statement: NC/Nga (NC) mice produced high levels of ovalbumin (OVA)-specific IgG, IgG1 and IgG2a. We previously found deletion polymorphisms in the promoter region of fcgr2b in NC mice. To determine whether this mutation causes a hyper-humoral immune response, we generated congenic BALB/c mice carrying the NC-type fcgr2b allele (NC fcgr2b) and analyzed humoral immune response and FcγRIIB on germinal … …American Journal of Immunology, Vol. 5, Issue 3 · 31 Dec 2009 · 7,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractSerological Evaluation of Brucella abortus S99 Lipopolysaccharide Extracted by an Optimized MethodAli Sharifat Salmani, Seyed Davar Siadat, Mohammad Reza Fallahian et al.Problem statement: Brucellosis is a globally found infectious disease and there is no licensed vaccine against human brucellosis. The present study carried-out to evaluate the potency of our modified extracted lipopolysaccharide (LPS) of B. abortus to elicit specific anti-Brucella antibodies in animal model (Rabbit) as a part of a candidate vaccine for brucellosis. Lipopolysaccharide is one of the main virulence … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 9,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHumoral and Cellular Effects of Stress-An Extensive Model SystemMazal Shimon-Hophy, Ramy R. AvtalionThe influence of stress on the immune system of the common carp (Cyprinus carpio) was studied by measuring leukocytes levels using flow cytometry and mRNA immune components by real time qPCR. Acute and chronic oxidative stresses were generated by different regimes of exposure of carp to environmental air. In acute stress, induced by single air exposure, the pro-inflammatory cytokines (IL1β, … …American Journal of Immunology, Vol. 13, Issue 2 · 18 Apr 2017 · 6,724 accessesView PDFCite
