Study sheds new light on neurobiological processes that control drug-related adaptations

The lab of Jeremy Day, Ph.D., at the University of Alabama at Birmingham, has used single-nucleus RNA sequencing approaches to compare transcriptional responses to acute cocaine in 16 unique cell populations from a portion of the brain called the nucleus accumbens, or NAc.

GIRK channel activator can provide potential treatments for brain disorders

Potassium channels play an important role in controlling the electrical activity of neurons in the brain.

Researchers track brain receptor as it transmits or inhibits neural signals

For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals. Critical for brain development and function, the receptor converts chemical messages between cells into electrical signals within a neuron.

Researchers identify a novel mutation through whole-exome sequencing

Long QT syndrome (LQTS), caused by an ion channel-related gene mutation, is a malignant heart disease with a clinical course of a high incidence of ventricular fibrillation and sudden cardiac death in the young.

Researchers identify mouse model that mimics HFpEF syndrome in humans

A receptor that plays an essential role in safely clearing chronic unresolved cardiac inflammation may offer new targets for treating an increasing type of heart failure associated with age-related obesity, suggests a preclinical study led by researchers at the University of South Florida Health Heart Institute, Morsani College of Medicine.

Mutations linked to intellectual disability, epileptic seizures affect ion channel's function

Two mutations identified in individuals with developmental and epileptic brain disease can be traced back to the same ion channel.

Genetic marker may predispose African Americans to cardiac complications from COVID-19

Nearly one out of every 10 African Americans has a genetic variant that puts them inherently at an increased risk for ventricular arrhythmias and sudden cardiac death.

Chemotherapy and cancer join together to cause neuropathy

Contrary to common medical guidance, chemotherapy does not appear to be the only culprit in neuropathy, a neurological side effect of cancer treatment, a new study says. Cancer itself contributes heavily, too, and the stresses on neurons appear far worse than the sum of the two causes.

Tanycytes in the brain play an active role in increasing appetite

Tanycytes are glial cells, which communicate with neurons in the brain to inform it of what we have eaten. Researchers from the School of Life Sciences at the University of Warwick have found when tanycytes are selectively stimulated appetite was increased.

JGU professor wins Exploration Grant for research into membrane proteins of parasites

So-called neglected tropical diseases (NTDs) cause great suffering in some of the world's poorest countries and can lead also to significant economic losses due to, for example, the infestation of animal herds.

Breakthrough discovery could lead to treatment of Fragile X syndrome

Scientists at the Hotchkiss Brain Institute, Alberta Children's Hospital Research Institute, and Owerko Centre at UCalgary's Cumming School of Medicine have made a breakthrough discovery that could lead to treatment of Fragile X syndrome, the leading genetic cause of Autism Spectrum Disorder.

Frog brain discovery may pave the way for repairing birth defects in humans

A team of researchers from Tufts University, Universitat de Valencia, and Harvard University has discovered that the brains of developing frog embryos damaged by nicotine exposure can be repaired by using “ionoceuticals” that can help in the recovery of bioelectric patterns in the embryo.

Research identifies a disease trigger for pancreatitis

One factor contributing to the development of pancreatitis lies in mutations within a cell membrane ion channel that is characterized by its specific permeability for calcium ions.

Study: Unique glucose-sensing neurons in the brain prevent severe hypoglycemia

Low blood sugar levels, known as hypoglycemia, can be a life-threatening situation, especially for people with type 1 diabetes who rely on intensive insulin therapy to prevent blood sugar from going too high.

UTSW researchers uncover shape of key protein involved in muscle contraction

Researchers at UT Southwestern Medical Center have uncovered the detailed shape of a key protein involved in muscle contraction. The report, published today in Neuron, may lead to improved understanding of muscle-weakening genetic conditions called congenital myasthenic syndromes.

Study provides insights into pain signaling mechanism in the brain

Fast communication between our brain cells - or neurotransmission as it is called - is hugely important for our brain to work properly. Some of the messengers involved in this form of communication are neuropeptides, which are chemicals produced in the brain.
