Adenosine A2A receptor activation is determinant for BDNF actions upon GABA and...
Vaz, Sandra H.; Lerias, Sofia; Parreira, Sara; Diógenes, Maria José; Sebastião, Ana MAdenosine, through A(2A) receptor (A(2A)R) activation, can act as a metamodulator, controlling the actions of other modulators, as brain-derived neurotrophic factor (BDNF). Most of the metamodulatory actions of adenosine in the hippocampus have been evaluated in excitatory synapses. However, adenosine and BDNF can also influence GABAergic transmission. We thus evaluated the role of A(2A)R on the modulatory effe...
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...
