Cannabinoid type 2 receptor inhibition enhances the antidepressant and proneuro...
Rodrigues, Rui S.; Moreira, João B.; Mateus, Joana; Barateiro, Andreia; Paulo, Sara L; Vaz, Sandra H.; Lourenço, Diogo M.; Ribeiro, Filipa; Soares, RitaChronic stress is a major risk factor for neuropsychiatric conditions such as depression. Adult hippocampal neurogenesis (AHN) has emerged as a promising target to counteract stress-related disorders given the ability of newborn neurons to facilitate endogenous plasticity. Recent data sheds light on the interaction between cannabinoids and neurotrophic factors underlying the regulation of AHN, with important ef...
Unravelling a novel role for cannabidivarin in the modulation of subventricular...
Lourenço, Diogo M.; Soares, Rita; Sá Santos, Sónia; Mateus, Joana; Rodrigues, Rui S.; Moreira, João B.; Vaz, Sandra H.; Sebastião, Ana M; Solá, SusanaPostnatal neurogenesis has been shown to rely on the endocannabinoid system. Here we aimed at unravelling the role of Cannabidivarin (CBDV), a non-psychoactive cannabinoid, with high affinity for the non-classical cannabinoid receptor TRPV1, on subventricular zone (SVZ) postnatal neurogenesis. Using the neurosphere assay, SVZ-derived neural stem/progenitor cells (NSPCs) were incubated with CBDV and/or 5'-Iodore...
Role of purines in brain development, from neuronal proliferation to synaptic r...
Rimbert, Solen; Moreira, João B.; Xapelli, Sara; Lévi, SabineThe purinergic system includes P1 and P2 receptors, which are activated by ATP and its metabolites. They are expressed in adult neuronal and glial cells and are crucial in brain function, including neuromodulation and neuronal signaling. As P1 and P2 receptors are expressed throughout embryogenesis and development, purinergic signaling also has an important role in the development of the peripheral and central ...
Coronal brain atlas in stereotaxic coordinates of the African spiny mouse, acom...
Vitorino, Marta; S, Simão; Moreira, João B.; Nogueira‐Rodrigues, Joana; Silva, Joana A; Sofia Lourenço, Ana; Vitor Fernandes, Dr; Sousa, Monica M.The African spiny mouse (Acomys cahirinus) is an emerging model of mammalian epimorphic regeneration that has aroused the interest of the scientific community in the last decade. To date, studies on brain repair have been hindered by the lack of knowledge on the neuroanatomy of this species. Here, we present a coronal brain atlas in stereotaxic coordinates, which allows for three-dimensional identification and ...
The mitochondrial antioxidant Sirtuin3 cooperates with lipid metabolism to safe...
Santos, Sónia Sá; Moreira, João B.; Costa, Márcia; Rodrigues, Rui S.; Sebastião, Ana M; Xapelli, Sara; Solá, SusanaNeural stem cells (NSCs), crucial for memory in the adult brain, are also pivotal to buffer depressive behavior. However, the mechanisms underlying the boost in NSC activity throughout life are still largely undiscovered. Here, we aimed to explore the role of deacetylase Sirtuin 3 (SIRT3), a central player in mitochondrial metabolism and oxidative protection, in the fate of NSC under aging and depression-like c...
The neurosphere assay : an effective in vitro technique to study neural stem cells
Xapelli, Sara; Soares, Rita; Ribeiro, Filipa; Lourenço, Diogo M.; Rodrigues, Rui S.; Moreira, João B.; Sebastião, Ana M.; Morais, Vanessa A.Neural stem cells (NSCs) are known to be present in the adult mammalian brain where they constitutively differentiate into the neuronal, astroglial, and oligodendroglial lineages, in defined processes termed n e u ro ge n e s i s , a st ro g l i o ge n e s i s a n d oligodendrogenesis, respectively (reviewed in Braun and Jessberger, 2014). During brain development, NSCs are present throughout the brain, becomin...
Cannabinoid actions on neural stem cells: implications for pathophysiology
Rodrigues, Rui S.; Lourenço, Diogo M.; Paulo, Sara L; Mateus, Joana; Ferreira, Miguel F.; Mouro, Francisco; Moreira, João B.; Ribeiro, FilipaWith the increase of life expectancy, neurodegenerative disorders are becoming not only a health but also a social burden worldwide. However, due to the multitude of pathophysiological disease states, current treatments fail to meet the desired outcomes. Therefore, there is a need for new therapeutic strategies focusing on more integrated, personalized and effective approaches. The prospect of using neural stem...
