GABA<sub>B</sub> Receptors Mediate Intracellular Calcium Release in Astrocytes of the Prefrontal Cortex. [PDF]
We took advantage of GLAST‐promoter driven GCaMP6s expression in astrocytes to study Ca2+ signaling in astrocytes of the young adult prefrontal cortex in response to GABA with confocal Ca2+ imaging. The results show that GABA induces Ca2+ signaling via the stimulation of the metabotropic GABAB receptor in astrocytes.

A PI3K-mediated negative feedback regulates Drosophila motor neuron excitability [PDF]
Negative feedback can act as a homeostatic mechanism to maintain neuronal activity at a particular specified value. At the Drosophila neuromuscular junction, a mutation in the type II metabotropic glutamate receptor gene (mGluRA) increased motor neuron ...

Therapeutic Targeting of the α7 Nicotinic Receptor: Challenges and Prospects for Cognitive Improvement in Alzheimer's and Schizophrenia [PDF]
ABSTRACT The α7 nicotinic acetylcholine receptor (α7 nAChR) has emerged as a key target for treating cognitive dysfunction in neurological disorders such as Alzheimer's disease (AD) and schizophrenia. α7 nAChRs play essential roles in neurotransmission, neuroinflammation and synaptic plasticity, not only in neurons but also in glial cells, where they ...

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

Abstract Objective Drug‐resistant epilepsy (DRE) affects >25 million people worldwide and is often associated with neuroinflammation. Increasing evidence links deficiency or malfunctioning of the enzyme phosphoglycerate dehydrogenase (PHGDH), which converts 3‐phosphoglycerate to generate serine and the neurotransmitter glycine, with (drug‐resistant ...

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

Metabotropic glutamate receptors in auditory processing [PDF]
As the major excitatory neurotransmitter used in the vertebrate brain, glutamate activates ionotropic and metabotropic glutamate receptors (mGluRs), which mediate fast and slow neuronal actions, respectively. Important modulatory roles of mGluRs have been shown in many brain areas, and drugs targeting mGluRs have been developed for the treatment of ...

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,
