Research ArticleOpen accessIn the abstractMicrobial Translocation and B Cell Dysfunction in Human Immunodeficiency Virus DiseaseWei JiangThe gut mucosal barrier disrupted in HIV disease, resulting in increased systemic exposure to microbial products such as Lipo Polys Accharide (LPS). The association of enhanced microbial translocation and B cell dysfunction in HIV disease is not fully understood. High dose and short term exposure of microbial Toll-Like Receptor (TLR) agonists were used as vaccine adjuvants, however, low dose and … …American Journal of Immunology, Vol. 8, Issue 2 · 30 Jun 2012 · 7,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractTramadol Vs Tapentadol: Anew Horizon in Pain Treatment?Mario GiorgiProblem statement: Acute and chronic pain is a common presenting sign in animal species and human beings. Approach: Classical opioids provide very effective pain relief, although they may be less effective in the treatment of chronic pain due to their limited therapeutic windows and the induced opioid receptor down regulation. Atypical opioids, such as tramadol and tapentadol, have a dual … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 25 Feb 2012 · 17,871 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn silico Modeling of α1A-Adrenoceptor: Interaction of its Normal and Mutated Active Sites with Noradrenaline as well as its Agonist and AntagonistRamchandran Vijayan, Naidu Subbarao, Birendra Nath MallickNoradrenaline, like most other neurotransmitters, acts through various adrenoceptor subtypes. The structure and active site of adrenoceptors for the binding of noradrenaline were unknown, however, such information are crucial for understanding the molecular mechanism of action of neurotransmitters, including noradrenaline, in health and disease as well as for drug designing. In this in silico study, we modeled the α1A-adrenoceptor; a … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 7,140 accessesView PDFCite
Research ArticleOpen accessIn the abstractNaloxone benzoylhydrazone activates Extracellular Signal-Regulated Protein Kinases and modulates Nociceptin Opioid Peptide Receptor activityDeepak R. Thakker, Ghazi F. Altememi, Chitra D. Mandyam et al.Naloxone benzoylhydrazone (NalBzoH) is often used as a nociceptin opioid peptide (NOP) receptor antagonist. However, NalBzoH is also a mixed μ antagonist/κ and δ opioid agonist and its actions at the NOP receptor range from an antagonist to partial agonist, depending on the effector response/system studied. We now report that NalBzoH activates endogenously expressed κ3 opioid, but not NOP, receptors … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,549 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of HIV-1 Infection in Addictive Behavior: A Study of a HIV-1 Transgenic Rat ModelSulie L. Chang, Michael VigoritoEpidemiological research indicates that drug abuse is prevalent among individuals infected with HIV-1. Evidence from preclinical research also suggests that drugs of abuse exacerbate the progression of neuropathological changes in the HIV-1 infected brain probably through common mechanisms of neuronal injury. The effects of HIV-1 on the efficacy and abuse potential of controlled drugs such as morphine, however, has not … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractLoss of Morphine-induced Suppression of NK Cell activity and T-cell Functions in µ-Opioid Receptor Knockout MiceRichard J. Weber, Ricardo Gomez-Flores, Ichiro Sora, George R. UhlIn vivo administration of µ-opioid receptor selective agonists to various species is known to suppress lymphocyte, NK cell, and macrophage functions, in addition to mediate pain relief and euphoria. Using a mouse model in which the µ-opioid receptor gene was disrupted by targeted homologous recombination, we explored the involvement of this receptor in natural killer (NK) cell activity and T … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,937 accessesView PDFCite
