Anxiolytic Effects of Indole Alkaloids From Rauvolfia ligustrina in Adult Zebrafish: Involvement of the GABAergic and 5‐HT Systems

Chemistry &Biodiversity, EarlyView.
ABSTRACT Benzodiazepines are widely used in the treatment of anxiety, but their use may be interrupted due to side effects. This study evaluated the indole alkaloids isocarapanaubine (indole alkaloid 1 [AIN1]) and 18‐β‐hydroxy‐3‐epi‐α‐yohimbine (indole alkaloid 2 [AIN2]), extracted from Rauvolfia ligustrina, in adult zebrafish.

Genetic Downregulation of GABA_B Receptors from Oligodendrocyte Precursor Cells Protects Against Demyelination in the Mouse Spinal Cord

Cells
GABAergic signaling and GABAB receptors play crucial roles in regulating the physiology of oligodendrocyte-lineage cells, including their proliferation, differentiation, and myelination.

Decreased GABA receptor in the cerebral cortex of epileptic rats: effect of Bacopa monnieri and Bacoside-A

Journal of Biomedical Science, 2012
Abstact Background Gamma amino butyric acid (GABA), the principal inhibitory neurotransmitter in the cerebral cortex, maintains the inhibitory tones that counter balances neuronal excitation. When this balance is perturbed, seizures may ensue. Methods In

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Functional Characterization of Native, High-Affinity GABAA Receptors in Human Pancreatic β Cells

EBioMedicine, 2018
In human pancreatic islets, the neurotransmitter γ-aminobutyric acid (GABA) is an extracellular signaling molecule synthesized by and released from the insulin-secreting β cells.

Fast detection of extrasynaptic GABA with a whole-cell sniffer

Frontiers in Cellular Neuroscience, 2014
Gamma-amino-butyric acid (GABA) is the main inhibitory transmitter of the brain. It operates by binding to specific receptors located both inside and outside synapses.

Synthesis of Substituted Imidazo[1,2‐a]pyridines, Imidazo[1,2‐a]pyrazines and Imidazo[1,2‐b]pyridazines by Multicomponent Reactions Using Green Solvents

European Journal of Organic Chemistry, EarlyView.
In an environmentally friendly process for synthesizing heterocyclic molecules of therapeutic interest, imidazo[1,2‐a]pyridine, imidazo[1,2‐a]pyrazine and imidazo[1,2‐b]pyridazine core structures are obtained by a multicomponent Groebke–Blackburn–Bienaymé reaction using bio‐based recyclable solvents.

Neurally Released GABA Acts via GABAC Receptors to Modulate Ca2+ Transients Evoked by Trains of Synaptic Inputs, but Not Responses Evoked by Single Stimuli, in Myenteric Neurons of Mouse Ileum

Frontiers in Physiology, 2018
γ-Aminobutyric Acid (GABA) and its receptors, GABAA,B,C, are expressed in several locations along the gastrointestinal tract. Nevertheless, a role for GABA in enteric synaptic transmission remains elusive.
