Environmental Enrichment Rescues Endocannabinoid-Dependent Synaptic Plasticity Lost in Young Adult Male Mice after Ethanol Exposure during Adolescence
(MDPI, 2021-07-16)
Binge drinking (BD) is a serious health concern in adolescents as high ethanol (EtOH) consumption can have cognitive sequelae later in life. Remarkably, an enriched environment (EE) in adulthood significantly recovers ...
Lack of the transient receptor potential vanilloid 1 shifts cannabinoid-dependent excitatory synaptic plasticity in the dentate gyrus of the mouse brain hippocampus
(Frontiers Media, 2021-07-07)
[EN] The transient receptor potential vanilloid 1 (TRPV1) participates in synaptic functions
in the brain. In the dentate gyrus, post-synaptic TRPV1 in the granule cell (GC)
dendritic spines mediates a type of long-term ...
Clemastine Induces an Impairment in Developmental Myelination
(Frontiers Media, 2022)
[EN] Abnormalities in myelination are associated to behavioral and cognitive dysfunction in neurodevelopmental psychiatric disorders. Thus, therapies to promote or accelerate myelination could potentially ameliorate symptoms ...
Contribution of P2X4 Receptors to CNS Function and Pathophysiology
(MDPI, 2020-08-03)
The release and extracellular action of ATP are a widespread mechanism for cell-to-cell communication in living organisms through activation of P2X and P2Y receptors expressed at the cell surface of most tissues, including ...
Role of Mitochondrial Dynamics in Microglial Activation and Metabolic Switch
(American Association Of Immunologists, 2021-08-10)
Microglia act as sensors of injury in the brain, favoring its homeostasis. Their activation and polarization toward a proinflammatory phenotype are associated with injury and disease. These processes are linked to a metabolic ...
Functional and Metabolic Characterization of Microglia Culture in a Defined Medium
(Frontiers Media, 2020-02-07)
Microglia are the endogenous immune cells of the brain and act as sensor of infection and pathologic injury to the brain, leading to a rapid plastic process of activation that culminates in the endocytosis and phagocytosis ...
Neurotransmitter signaling in the pathophysiology of microglia
(Frontiers Research Foundation, 2013)
Microglial cells are the resident immune cells of the central nervous system. In the resting state, microglia are highly dynamic and control the environment by rapidly extending and retracting motile processes. Microglia ...
Endocannabinoid LTD in Accumbal D1 Neurons Mediates Reward-Seeking Behavior
(Cell Press, 2020-03-27)
The nucleus accumbens (NAc) plays a key role in drug-related behavior and natural reward learning. Synaptic plasticity in dopamine D1 and D2 receptor medium spiny neurons (MSNs) of the NAc and the endogenous cannabinoid ...
Singular Location and Signaling Profile of Adenosine A2A-Cannabinoid CB1 Receptor Heteromers in the Dorsal Striatum
(Nature Publishing Group, 2018-04)
The dorsal striatum is a key node for many neurobiological processes such as motor activity, cognitive functions, and affective processes. The proper functioning of striatal neurons relies critically on metabotropic ...
Endocannabinoid long-term depression revealed at medial perforant path excitatory synapses in the dentate gyrus
(Elsevier, 2019-04-22)
The endocannabinoid system modulates synaptic plasticity in the hippocampus, but a link between long-term synaptic plasticity and the type 1 cannabinoid (CB1) receptor at medial perforant path (MPP) synapses remains elusive. ...
