Sex differences in AMPA receptor trafficking proteins

Biology of Sex Differences
AMPA receptors are a type of ionotropic glutamate receptor that is important for fast excitatory neurotransmission. healthy brain function. Glutamate signaling is regulated, in part, by the trafficking of glutamate receptors in and out of the synapse ...

m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy

Annals of Neurology, EarlyView.
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

Gut–Brain Axis Modulation by Short‐Chain Fatty Acids Exerts Disease‐Modifying Effects in a Murine Model of Drug‐Resistant Epilepsy

Annals of Neurology, EarlyView.
Objective Drug‐resistant epilepsy (DRE) remains a clinical challenge, as therapies modifying disease trajectory are lacking. Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short‐chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti‐inflammatory properties.

Plasticity of GABAB receptor-mediated heterosynaptic interactions at mossy fibers after status epilepticus

, 2003
Several neurotransmitters, including GABA acting at presynaptic GABAB receptors, modulate glutamate release at synapses between hippocampal mossy fibers and CA3 pyramidal neurons.

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study

, 2008
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.
