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 consumed psychoactive substance worldwide. Strikingly, 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 hippocampus, at the...

Exacerbation of C1q dysregulation, synaptic loss and memory deficits in tau pat...
Carvalho, Kevin; Faivre, Emilie; Pietrowski, Marie J.; Marques, Xavier; Gomez-Murcia, Victoria; Deleau, Aude; Huin, Vincent; Hansen, Jan NAccumulating data support the role of tau pathology in cognitive decline in ageing and Alzheimer's disease, but underlying mechanisms remain ill-defined. Interestingly, ageing and Alzheimer's disease have been associated with an abnormal upregulation of adenosine A2A receptor (A2AR), a fine tuner of synaptic plasticity. However, the link between A2AR signalling and tau pathology has remained largely unexplored....
Beneficial effect of a selective adenosine A2A receptor antagonist in the APPsw...
Faivre, Emilie; Coelho, Joana E; Zornbach, Katja; Malik, Enas; Baqi, Younis; Schneider, Marion; Cellai, Lucrezia; Carvalho, Kevin; Sebda, ShéhérazadeConsumption of caffeine, a non-selective adenosine A2A receptor (A2AR) antagonist, reduces the risk of developing Alzheimer's disease (AD) and mitigates both amyloid and Tau lesions in transgenic mouse models of the disease. While short-term treatment with A2AR antagonists have been shown to alleviate cognitive deficits in mouse models of amyloidogenesis, impact of a chronic and long-term treatment on the devel...
