Research ArticleOpen accessLoss 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 PDF Cite

Research ArticleOpen accessIn vitro Activation of Human and Rat Lymphocyte and Macrophage Functions by NorepinephrineRicardo Gomez-Flores, Diana Caballero-Hernandez, Richard J. Weber et al.Norepinephrine (NE) has been associated not only with increasing blood pressure, atherosclerosis, heart disease, and other life threatening conditions, but also with altering immune responses by influencing leukocyte functions. In the present study, we evaluated the in vitro effects of NE on rat thymic lymphocyte and human peripheral blood mononuclear cells (HPBMC) functions. We observed that NE marginally, but significantly … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,075 accessesView PDF Cite

Research ArticleOpen accessSelective Lymphocyte Activation and Inhibition of In Vitro Tumor Cell Growth by Novel MorphinansRicardo Gomez-Flores, Kimberly R. Vietti, William J. Dunn et al.Opioids can suppress immune functions and increase susceptibility to developing cancer and infectious diseases. Recently, novel opioid compounds have been synthesized that lack immunosuppressive effects. We evaluated the effects of morphinans with substituted pyrimidine (methyl, phenyl, hydroxy, and amino groups) and pyrazole groups on in vitro rat thymic lymphocyte and splenic macrophage functions, and tumor cell growth. We observed that … …American Journal of Immunology, Vol. 2, Issue 1 · 5 Mar 2005 · 7,078 accessesView PDF Cite
