Stimulation of Neural Stem Cell Proliferation by Inhibition of Phosphodiesterase 5
Santos, Ana I.; Carreira, Bruno P.; Nobre, Rui J.; Carvalho, Caetana M.; Araujo, Ines M.The involvement of nitric oxide (NO) and cyclic GMP (cGMP) in neurogenesis has been progressively unmasked over the last decade. Phosphodiesterase 5 (PDE5) specifically degrades cGMP and is highly abundant in the mammalian brain. Inhibition of cGMP hydrolysis by blocking PDE5 is a possible strategy to enhance the first step of neurogenesis, proliferation of neural stem cells (NSC). In this work, we have studied...
Evaluation of neurotoxic and neuroprotective pathways affected by antiepileptic...
Morte, Maria I.; Carreira, Bruno P.; Falcão, Maria J.; Ambrosio, António M.; Soares-da-Silva, Patrício; Araújo, Inês M.; Carvalho, Caetana M.In this study we evaluated the neurotoxicity of eslicarbazepine acetate (ESL), and of its in vivo metabolites eslicarbazepine (S-Lic) and R-licarbazepine (R-Lic), as compared to the structurally-related compounds carbamazepine (CBZ) and oxcarbazepine (OXC), in an in vitro model of cultured rat hippocampal neurons. The non-related antiepileptic drugs (AEDs) lamotrigine (LTG) and sodium valproate (VPA) were also ...
