Protein connectivity in chemotaxis receptor complexes [PDF]

open access: yes, 2015
The chemotaxis sensory system allows bacteria such as Escherichia coli to swim towards nutrients and away from repellents. The underlying pathway is remarkably sensitive in detecting chemical gradients over a wide range of ambient concentrations. Interactions among receptors, which are predominantly clustered at the cell poles, are crucial to this ...

Output of neurogliaform cells to various neuron types in the human and rat cerebral cortex

open access: yesFrontiers in Neural Circuits, 2007
Neurogliaform cells in the rat elicit combined GABAA and GABAB receptor-mediated postsynaptic responses on cortical pyramidal cells and establish electrical synapses with various interneuron types.

Postsynaptic GABAB Receptors Enhance Extrasynaptic GABAA Receptor Function in Dentate Gyrus Granule Cells

open access: yesJournal of Neuroscience, 2013
Ambient GABA in the brain tonically activates extrasynaptic GABAA receptors, and activity-dependent changes in ambient GABA concentration can also activate GABAB receptors.

Adhesion of membranes via receptor-ligand complexes: Domain formation, binding cooperativity, and active processes [PDF]

open access: yes, 2009
Cell membranes interact via anchored receptor and ligand molecules. Central questions on cell adhesion concern the binding affinity of these membrane-anchored molecules, the mechanisms leading to the receptor-ligand domains observed during adhesion, and the role of cytoskeletal and other active processes.

Temporal Profiling of Male Cortical Astrocyte Transcription Predicts Molecular Shifts From Early Development to Aging

open access: yesGlia, EarlyView.
Comprehensive analysis of cortical astrocyte gene expression across the lifespan. Profiling dynamic changes of key astrocyte genes reveals functional shifts. Astrocytes contribute to gene‐length‐dependent transcription decline in the aging brain. ABSTRACT Astrocytes are the most abundant glial cell type in the central nervous system (CNS).

Maternal restraint stress delays maturation of cation-chloride cotransporters and GABAA receptor subunits in the hippocampus of rat pups at puberty

open access: yesNeurobiology of Stress, 2016
The GABAergic synapse undergoes structural and functional maturation during early brain development. Maternal stress alters GABAergic synapses in the pup's brain that are associated with the pathophysiology of neuropsychiatric disorders in adults ...

Astroglial CB1 Reveal Sex‐Specific Synaptic Effects of Amphetamine

open access: yesGlia, EarlyView.
Astroglial CB1R mediates long‐term synaptic plasticity (LTD) in the Nucleus accumbens. Amphetamine saturates adenosine receptors and blocks LTD in males, but not females. Locomotor effects of amphetamine require astroglial CB1R in males, but not in females.

Three epilepsy-associated GABRG2 missense mutations at the γ+/β− interface disrupt GABAA receptor assembly and trafficking by similar mechanisms but to different extents

open access: yesNeurobiology of Disease, 2014
We compared the effects of three missense mutations in the GABAA receptor γ2 subunit on GABAA receptor assembly, trafficking and function in HEK293T cells cotransfected with α1, β2, and wildtype or mutant γ2 subunits.

Mechanisms Underlying Tolerance after Long-Term Benzodiazepine Use: A Future for Subtype-Selective GABAA Receptor Modulators?

open access: yesAdvances in Pharmacological Sciences, 2012
Despite decades of basic and clinical research, our understanding of how benzodiazepines tend to lose their efficacy over time (tolerance) is at least incomplete.

Research progress on the mechanisms of pain empathy

open access: yesIbrain, EarlyView.
This article is related to the graphical research progress of pain empathy, starting with the description of the pain matrix and mirror neurons. Based on the pain matrix and mirror neurons, pain empathy results from the combined action of brain regions such as the anterior cingulate cortex, insula, prefrontal cortex, and amygdala and regulatory ...
