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 abstractLevamisole Enhances Cell-Mediated Immune Responses and Reduces Shedding of H9N2 Avian Influenza Virus in Japanese Quails (Coturnix coturnix japonica)Tahoora Shomali, Najmeh Mosleh, Arash AlaeddiniProblem statement: Regarding the role of Japanese quails (Coturnix coturnix japonica) in reassortment and spreading of avian influenza (AI) viruses and inadequate protection of vaccination in this species, the present study aimed to evaluate the effect of levamisole as an immunomodulatory agent on cell-mediated immunity (CMI), antibody responses and shedding of H9N2 AI virus in experimentally infected quails. Approach: On … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 6 Mar 2012 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating the Effect of Booster Dose of Hepatitis B Vaccine in Low-and Non-Responders Healthcare Workers and the Role of some Host-Related FactorsMojtaba Varshochi, Mehdi HaghdoostProblem statement: Hepatitis B comprises one of the major health problems worldwide. Health Care Workers (HCW) are a group at risk for Hepatitis B Virus (HBV) infection. Infection with hepatitis B virus has become a vaccine-preventable disease. Vaccination against Hepatitis B Virus infection (HBV) is safe and effective. The aim of this study is evaluation the immunologic response of booster … …American Journal of Immunology, Vol. 7, Issue 2 · 4 Nov 2011 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeroprevalence of Neospora Caninum in Stray DogsGaredaghi YagoobProblem statement: To investigate anti-Neospora caninum antibodies in stray dogs living in Tabriz city, 100 blood samples were collected. Serum samples were screened for detection of anti-N. caninum IgG antibodies using Indirect Fluorescent Antibody Test (IFAT; ≥50). Antibodies were seen in 31 (31%) of 100 dogs. Approach: The IFAT antibody titers were as follows: 1:50 in 11 dogs, 1:100 in … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 3 · 5 Oct 2011 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Methionine and Threonine Supplementations on Immune Responses of Broiler Chickens Challenged with Infectious Bursal DiseaseElham Maroufyan, Azhar Kasim, Seyed Reza Hashemi et al.Problem statement: The aim of this study was conducted to determine the effects of supplementing methionine and threonine higher than the National Research Council (NRC) recommendation in the diets on immune responses of broiler chickens challenged with Infectious Bursal Disease (IBD). Approach: A total of 450 day-old male broiler chicks were assigned to one of the nine dietary treatments. Three … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,844 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of the Salivary Anti-Phenolic Glycolipid-1 Antibody in Leprosy Patients as a Tool to Monitoring MultidrugtherapyN. L.B. Bonfitto, A. C.F. Motta, R. B. Furini et al.Problem statement: The upper airways has a great importance as a route of M. leprae infection and because of the possibility of identifying relevant tools by systematic patient evaluation, the detection of leprosy patients by means of salivary markers becomes important. The aim of this study was to analyze anti-phenolic glycolipid 1 (anti-PGL-1) salivary and serum titers as parameters for … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 8,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of a DNA Vaccine for Immunocontraceptive Potential Against Zona Pellucida Glycoproteins in CattleC.A. Foley, S.M. Boyle, R.E. Pearson, F.C. GwazdauskasHolstein cows were administered zona pellucida (ZP) DNA vaccine and used to determine the potential of recombinant rabbit ZP glycoproteins (rZP) as immunocontraceptive antigens. Zona pellucida proteins were purified and quantified. Cows were assigned to one of four treatment groups in which plasmids encoding rabbit ZP proteins were administered, i.d., using a gene gun (ZP55, n=2; ZP75, n=2; Hep55, n=2; … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,888 accessesView PDFCite

Research ArticleOpen accessIn the abstractImmunological Response of Albino Rats Immunized with UV-Killed Candida albicansAhmad Ibrahim, Yahaya Abdullahi Umar, Mohammed Shehu BusuThe treatments of systemic candidiasis in humans with the current antifungal drugs of choice such as azole derivatives and amphotericin B have raised issues of toxicity and resistance among others. The immunogenic property of killed C. albicans was explored to evoke immunological response in the possible prevention of candidemia. Rats were immunized after acclimatization on two occasions with 106 cells/ml … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 26 Jul 2019 · 7,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractGlucans and the Poultry Immune SystemJacqueline Jacob, Anthony PescatoreWith the reduced availability of antibiotics, poultry producers are looking for feed additives to stimulate the immune system of their birds. Some beta-glucans have been shown to improve gut health in poultry subjected to a bacterial challenge, to increase the flow of new immunocytes into the various lymphoid organs, to increase macrophage function, to increase antibody titers after a vaccination … …American Journal of Immunology, Vol. 13, Issue 1 · 12 Apr 2017 · 12,367 accessesView PDFCite
