A Gut Feeling about GABA: Focus on GABAB receptors
Gamma-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the body and hence GABA-mediated neurotransmission regulates many physiological functions, including those in the gastrointestinal (GI) tract.

Emerging neurotrophic role of GABAB receptors in neuronal circuit development [PDF]
The proper development of highly organized structures in the central nervous system is a complex process during which key events – neurogenesis, migration, growth, differentiation, and synaptogenesis – have to take place in an appropriate manner to ...

In Vivo GABA Detection by Single Pulse Editing with One Shot [PDF]
Over the past two decades, magnetic resonance spectroscopy with two-shot difference editing has been widely employed to characterize altered levels of GABA, the primary inhibitory neurotransmitter in the brain, in various neuropsychiatric disorders. This conventional technique detects the GABA H4 resonance, making it unsuitable for investigating GABA ...

Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Main Point Loss of oligodendrocyte ErbB receptor signaling leads to A1 hypomyelination, reduced PV expression and density of PV+ neurons and synapses, hypoconnectivity of inhibitory circuits and shift of the E/I balance towards excitation. Abstract For a long time, myelin was thought to be restricted to excitatory neurons, and studies on dysmyelination

Midazolam inhibits hippocampal long-term potentiation and learning through dual central and peripheral benzodiazepine receptor activation and neurosteroidogenesis [PDF]
Benzodiazepines (BDZs) enhance GABA(A) receptor inhibition by direct actions on central BDZ receptors (CBRs). Although some BDZs also bind mitochondrial receptors [translocator protein (18 kDa) (TSPO)] and promote the synthesis of GABA-enhancing ...

New research reveals that oxytocin signaling during the early postnatal period is critical for regulating brain development and social behavior. Selectively suppressing oxytocin neurons by chemogenetic method shows that early—but not late—disruption leads to autism‐like behaviors.

Regulation of GABAA Receptors Induced by the Activation of L-Type Voltage-Gated Calcium Channels
GABAA receptors are pentameric ion channels that mediate most synaptic and tonic extrasynaptic inhibitory transmissions in the central nervous system.

Nicotinic α7 acetylcholine receptor-mediated currents are not modulated by the tryptophan metabolite kynurenic acid in adult hippocampal interneurons [PDF]
The tryptophan metabolite, kynurenic acid (KYNA), is classically known to be an antagonist of ionotropic glutamate receptors. Within the last decade several reports have been published suggesting that KYNA also blocks nicotinic acetylcholine receptors (nAChRs) containing the \alpha7 subunit (\alpha7*).

The gut microbiome is a potential target for treating cardiovascular disease. It is found that prophylactic administration of Flavonifractor plautii or its metabolite desaminotyrosine (DAT) exerts pleiotropic cardioprotective effects via promoting cardiomyocyte survival and attenuating cardiac inflammation against myocardial ischemia/reperfusion (I/R ...
