Research ArticleOpen accessIn the abstractUnderstand the Role of Natural KillerHan Yuen Lam, Swee Keong Yeap, Noorjahan Banu Alitheen et al.Problem statement: Immunosuppression is a common approach for pathogens or cancer to escape from immune system of the infected host. Some of the antimicrobe or anticancer drugs may also weaken the body immune system. Among various types of immune cell, natural killer cells are the key component of the innate immunity which plays an important role in first line defense … …American Journal of Immunology, Vol. 6, Issue 4 · 5 Aug 2011 · 7,938 accessesView PDFCite

Prothrombotic factors might play an important role in this phenomenon. Inflammation plays a pivotal role in atherosclerosis and coronary heart disease. Cardiotrophin-1 (CT-1), a member of the IL-6 family of cytokines, was identified as a growth factor for cardiac myocytes that induces cardiomyocyte hypertrophy and stimulates cardiac … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,243 accessesView PDFCite

Chao, A. GhorpadeProblem statement: Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and its cognate targets, the Matrix Metalloproteinases (MMPs), were differentially expressed in human brain samples with or without HIV-1 infection or HIV-1 Encephalitis (HIVE). Approach: A through literature review demonstrated that cell culture models of Central Nervous System (CNS) cell types had been used to illustrate the intricate temporal patterns of TIMP-1/MMP expression, … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,957 accessesView PDFCite

Krishnaraju, Chundi B.M. Rao, Dodda Sundararaju et al.Problem statement: Anti-inflammatory agents, particularly steroids and cyclooxygenase inhibitors are often associated with adverse side effects including, GI irritation, ulcers, hypertension and cardiac abnormalities. A safe and effective intervention is essential for the treatment of inflammatory disorders. Approach: Abstract Vitex leucoxylon L., a medicinal plant of the verbenaceae family, used in traditional medicine for relieving headache and catarrh. VL-89/185A, was … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of IL-17 and IL-23 in Plasma Samples of Children with AutismAmanda Enstrom, Charity Onore, Irva Hertz-Picciotto et al.Interleukin-23 (IL-23) is a survival factor for a newly described population of T lymphocytes, namely Th-17 cells, that secrete IL-17, tumor necrosis factor- alpha (TNFα) and IL-6. It has been shown that Th-17 cells are a pathogenic T cell subset involved in autoimmune and chronic inflammatory diseases. Based on the increasing evidence of immune dysfunction in autism, including possible autoimmune … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 8,228 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunopathogenesis of Dengue Hemorrhagic FeverHuan-Yao Lei, Kao-Jean Huang, Yee-Shin Lin et al.Dengue virus infection causes Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) whose pathogeneses were not clearly understood. A new hypothesis of immunopathogenesis is proposed for the development of the DHF/DSS. An aberrant immune over-activation after dengue virus infection not only impair the immune response to clear the virus, but also result in overproduction of cytokines … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 14,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutritional control of HIV-AIDS-A case for SeleniumParisa Kalantari, Hema Vunta, Umamaheswari D. Palempalli et al.Selenium (Se) is a micronutrient that is incorporated into proteins. Some of the selenoenzymes such as GPXs and thioredoxin reductases exhibit glutathione peroxidase-dependent activities towards organic and inorganic peroxides. Thus, selenoenzymes play a pivotal role in mitigating oxidative stress caused by accumulation of peroxides. In this respect, selenoproteins may interfere with the transcription-driven by oxidative stress-dependent signaling mechanisms to influence … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,346 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
