Caffeine intake exerts dual genome-wide effects on hippocampal metabolism and l...
Paiva, Isabel; Cellai, Lucrezia; Meriaux, Céline; Poncelet, Lauranne; Nebie, Ouada; Saliou, Jean-Michel; Lacoste, Anne-Sophie; Papegaey, AnthonyCaffeine is the most widely consumed psychoactive substance in the world. Strikingly, the molecular pathways engaged by its regular consumption remain unclear. We herein addressed the mechanisms associated with habitual (chronic) caffeine consumption in the mouse hippocampus using untargeted orthogonal omics techniques. Our results revealed that chronic caffeine exerts concerted pleiotropic effects in the hippo...
Dysregulation of TrkB receptors and BDNF function by amyloid-β peptide is media...
Jerónimo-Santos, André; Vaz, Sandra H.; Parreira, Sara; Lerias, Sofia; Caetano, António P.; Buée-Scherrer, Valérie; Castrén, Eero; Valente, Cláudia A.Brain-derived neurotrophic factor (BDNF) and its high-affinity full-length (FL) receptor, TrkB-FL, play a central role in the nervous system by providing trophic support to neurons and regulating synaptic plasticity and memory. TrkB and BDNF signaling are impaired in Alzheimer's disease (AD), a neurodegenerative disease involving accumulation of amyloid-β (Aβ) peptide. We recently showed that Aβ leads to a decr...
