Ketamine may help treat severe depression, reduce suicidal urges, UAB researchers say

University of Alabama at Birmingham researchers think ketamine, an anesthesia medication in use since the 1970s, might be a valuable tool in treating severe depression and reducing suicidal urges; they have launched two studies to explore the possibility.

Dysfunction of Calcium channel in neurons of cerebellum causes different motor diseases

A dysfunction of a certain Calcium channel, the so called P/Q-type channel, in neurons of the cerebellum is sufficient to cause different motor diseases as well as a special type of epilepsy.

Max Planck Florida Institute for Neuroscience gets grant for research into neurological disorders

The Max Planck Florida Institute for Neuroscience, the first and only U.S. extension of the prestigious Max Planck Society, today announced it has received approximately $1,257,500 in grant funding from prestigious national and international organizations to fund research into Parkinson-s, epilepsy and other neurological disorders.

Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

CALHM1 channel protein releases ATP to make neural taste connections

Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now.

CALHM1 protein plays critical role in sweet, bitter and umami taste perception

Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

Study shows how fish oils help lower blood pressure via vasodilation at ion channels

Omega-3 fatty acids found in oily fish may have diverse health-promoting effects, potentially protecting the immune, nervous, and cardiovascular systems.

Insight into how NMDA receptors function

In a pair of new papers, researchers at the University of California, San Diego School of Medicine and the Royal Netherlands Academy of Arts and Sciences upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons, and describe how a compound linked to Alzheimer's disease impacts that receptor and weakens synaptic connections between brain cells.

FSH, LH two important hormones that regulate puberty and maturation processes

FSH and LH are two important hormones which regulate the processes of puberty and maturation. These hormones are secreted by the pituitary gland and are transported in the blood to the genitalia, where they regulate maturation.

Activation of SK channels can lead to heart disease

Qing-Hui Chen's research focuses on hypertension, heart failure and the neuromechanisms that underlie these problems. Specifically, his research examines how a particular ion channel (that regulates resting and action in membranes)—the potassium channel (SK)—is linked to heart disease.

Previously poorly investigated signalling pathway crucial for proliferation of prostate cancer cells

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP.

Scientists identify cause of certain forms of epilepsy in cats

There is something sinister about epilepsy: the disease affects the very core of our being, our brain. Epileptic attacks can lead to seizures throughout the body or in parts of it. Clouding of consciousness or memory lapses are also possible. The causes are still only partially understood but in some cases brain tumours, infections, inflammations of the brain or metabolic diseases have been implicated.

Bioelectric signals can identify cells that are likely to develop into tumors

Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.

Molecular genetics expert wins Wolf Prize for his contribution to humanity

Joachim Messing, among the world's top experts in molecular genetics, became famous for developing a genetic engineering technique used in laboratories to create plants that have produced disease-resistant crops considered vital to feeding the world's population.

Researchers find new genetic differences in human hearts

Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments.

Chemical sensitivity of TRPA1 ion channel may boost melanin production

Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against DNA damage.

Model-independent way to study ion channel gating

Two studies in The Journal of General Physiology (JGP) help pave the way for a "shortcut" model-free approach to studying activation of "polymodal" ion channels-channels that open in response to multiple stimuli. Transmembrane ion channels respond to various physiological stimuli to regulate numerous cellular functions. Different classes of channels respond to different types of stimuli; some channels, for instance, respond to changes in membrane potential whereas others are activated by ligand binding.

Ion channel acts as powerful ‘brake’ after epileptic seizures

Given that epilepsy impacts more than 2 million Americans, there is a pressing need for new therapies to prevent this disabling neurological disorder. New findings from the neuroscience laboratory of Mark S. Shapiro, Ph.D., at The University of Texas Health Science Center at San Antonio, published Dec. 20 in the high-impact scientific journal, Neuron, may provide hope.
