Research ArticleOpen accessIn the abstractLemon Pepper Fruit Extract (Zanthoxylum acanthopodium DC.) Suppresses the Expression of Inflammatory Mediators in Lipopolysaccharide-Induced Macrophages In VitroYanti, Theodorus Eko Pramudito, Nerissa Nuriasari, Katarina JulianaProblem statement: Lemon pepper fruits (Zanthoxylum acanthopodium DC.; Rutaceae) have been used as a traditional source against stomach ache by Batak people in North Sumatera province, Indonesia. However, its scientific evidence for treatment of inflammatory disorders particularly gastritis has not been reported. Approach: Here, we investigated the inhibitory effects of Lemon Pepper Fruit Extract (LPFE) against inflammatory biomarkers by conducting … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 14 Feb 2012 · 9,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Salmonella enteritidis Outer Membrane Proteins and Lipopolysaccharide Profiles with the Detection of Immune Dominant ProteinsA. Maripandi, Ali A. Al-SalamahProblem statement: Salmonella infection is a serious medical and veterinary problem world-wide and causes great concern in the human health and food safety. Salmonella enteritidis outer membrane proteins and lipopolysaccharide play important role in the virulence and immunological properties of bacteria. Prophylaxis of enterobacterial infection has proven difficult to achieve. Vaccination is an effective tool for the prevention of Salmonella … …American Journal of Immunology, Vol. 6, Issue 1 · 21 Jun 2010 · 9,151 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 · 9,083 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunodeficient Parameters in the HIV-1 Transgenic Rat ModelSulie L. Chang, Frank Ocasio, Jose A. BeltranRecently an HIV-1 transgenic (HIV-1Tg) rat model was created that carries a gag-pol-deleted HIV-1 genome under the control of the HIV-1 viral promoter. However, other viral proteins are expressed in most organs and tissues, and are found in the circulating blood. Since HIV-1 targets the immune system in humans, we examined two immunological parameters, leukocyte-endothelial adhesion (LEA) and inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicroarray Analysis of Human Vascular Smooth Muscle Cell Responses to Bacterial LipopolysaccharideJoe Minta James, J. Yun, Sandy Der, Shikha RanaAccumulating evidence suggest a causal role of bacterial and viral infections in atherogenesis. Bacterial lipopolysaccharide (LPS) has been shown to stimulate resting vascular smooth muscle cells (SMC) with the production of inflammatory cytokines and modulation of quiescent cells to the proliferative and synthetic phenotype. To comprehensively identify biologically important genes associated with LPS-induced SMC phenotype modulation, we compared the transcriptomes … …American Journal of Immunology, Vol. 3, Issue 2 · 31 Dec 2007 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection against Lipopolysaccharide-induced Death by An Anti-Interleukin-6 Monoclonal AntibodyBailin Liang, Debra Gardner, Don Griswold, Xiao-yu R. SongSepticemia is frequently associated with serious complications and high mortality despite recent advances in treatment with antibacterial agents. Infectious organisms or their soluble products initiate septic shock through a complex cytokine cascade. Lipopolysaccharide (LPS) induced excessive production of inflammatory cytokines is regarded as a model of septic shock. Experiments of LPS-induced excessive cytokine production were conducted in Balb/c mice for … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 6,861 accessesView PDFCite
