Research ArticleOpen accessIn the author namesHyper-Ag-specific Ab Production in NC/Nga Mice is not associated with Deletion Polymorphism in the Promotor Region of the FcγRIIB GeneTohru Sakai, Mariko Nakamoto, Emi SutoProblem statement: NC/Nga (NC) mice produced high levels of ovalbumin (OVA)-specific IgG, IgG1 and IgG2a. We previously found deletion polymorphisms in the promoter region of fcgr2b in NC mice. To determine whether this mutation causes a hyper-humoral immune response, we generated congenic BALB/c mice carrying the NC-type fcgr2b allele (NC fcgr2b) and analyzed humoral immune response and FcγRIIB on germinal … …American Journal of Immunology, Vol. 5, Issue 3 · 31 Dec 2009 · 7,366 accessesView PDF Cite

Research ArticleOpen accessIn the author namesγ-Aninobutyric acid (GABA) suppresses antigen-specific immune responses in ovalbumin γ(OVA)-immunized BALB/c miceTohru Sakai, Hiroko Okada, Mitsuo Kise et al.γ-Aminobutruic acid (GABA) is known to be a ubiquitous inhibitory neurotransmitter in the central nervous system. Furthermore, recent studies have shown that GABA modulates cardiovascular and respiratory functions. In this study, we examined the effect of GABA on antigen (Ag)-specific immune responses and elucidated the mechanisms underlying those effects in ovalbumin (OVA)-immunized BALB/c mice. OVA-specific proliferative responses were decreased in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,503 accessesView PDF Cite
