PI3K activation promotes the formation of synaptic contacts and dendritic spines, morphological features of glutamatergic synapses that are commonly known to be related to learning processes. In this report, we show that in vivo administration of a peptide that activates the PI3K signaling pathway increases spine density in the rat hippocampus and enhances the animals' cognitive abilities, while in vivo electrophysiological recordings show that PI3K activation results in synaptic enhancement of Schaffer and stratum lacunosum moleculare inputs.

Methods: We evaluated the activation of CRTC1 in the hippocampus of control mice and mice lacking the Alzheimer’s disease–linked presenilin genes (presenilin conditional double knockout [PS cDKO]) after one-trial contextual fear conditioning by using biochemical, immunohistochemical, and gene expression analyses.

24 p, 5.5 MB GSK3β inhibition promotes synaptogenesis in Drosophila and mammalian neurons / Cuesto, Germán (Centro de Investigación Biomédica de La Rioja (Logronyo)) ; Jordán-Álvarez, Sheila (Instituto Cajal (Madrid, Espanya)) ; Enríquez-Barreto, Lilian (Centro de Investigación Biomédica de La Rioja (Logronyo)) ; Ferrús, Alberto (Instituto Cajal (Madrid, Espanya)) ; Morales, Miguel (Centro de Investigación Biomédica de La Rioja (Logronyo)) ; Acebes, Ángel (Instituto Cajal (Madrid, Espanya))
The PI3K-dependent activation of AKT results in the inhibition of GSK3β in most signaling pathways. These kinases regulate multiple neuronal processes including the control of synapse number as shown for Drosophila and rodents. [...]

14 p, 2.8 MB Gene expression parallels synaptic excitability and plasticity changes in Alzheimer's disease / Saura Antolín, Carlos A. (Carlos Alberto) (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular) ; Parra Damas, Arnaldo J. (Universitat Autònoma de Barcelona. Institut de Neurociències) ; Enríquez-Barreto, Lilian (Universitat Autònoma de Barcelona. Institut de Neurociències)
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by abnormal accumulation of β-amyloid and tau and synapse dysfunction in memory-related neural circuits. Pathological and functional changes in the medial temporal lobe, a region essential for explicit memory encoding, contribute to cognitive decline in AD. [...]
