We previously reported that brain-derived neurotrophic factor (BDNF) regulates both food intake and blood glucose metabolism in rodent obese diabetic models such as C57BL/KsJ-lepr(db)/lepr(db) (db/db) mice. To elucidate the effect of BDNF on glucose metabolism, we designed a novel pellet pair-feeding apparatus to eliminate the effect of appetite alteration(More)
Expression of the p16(Ink4a) tumor suppressor gene, a sensor of oncogenic stress, is up-regulated by a variety of potentially oncogenic stimuli in cultured primary cells. However, because p16(Ink4a) expression is also induced by tissue culture stress, physiological mechanisms regulating p16(Ink4a) expression remain unclear. To eliminate any potential(More)
The roles of autoimmune regulator (Aire)-expressing medullary thymic epithelial cells (mTECs) in the organization of the thymic microenvironment for establishing self-tolerance are enigmatic. We sought to monitor the production and maintenance of Aire-expressing mTECs by a fate-mapping strategy in which bacterial artificial chromosome transgenic (Tg) mice(More)
Factors that determine the spectrum of target organs involved in autoimmune destruction are poorly understood. Although loss of function of autoimmune regulator (AIRE) in thymic epithelial cells is responsible for autoimmunity, the pathogenic roles of AIRE in regulating target-organ specificity remain elusive. In order to gain insight into this issue, we(More)
Signal transduction pathways regulating NF-kappaB activation essential for microenvironment formation in secondary lymphoid organs remain to be determined. We investigated the effect of a deficiency of TNFR-associated factor 6 (TRAF6), which activates the classical NF-kappaB pathway, in splenic microenvironment formation. Two-week-old TRAF6-deficient mice(More)
