Liver-produced hormone protects mice against the harmful effects of intoxication

A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn't receive this treatment, UT Southwestern researchers report in a new study.

First wiring map of neurons in insect brain complete

Researchers have built the first ever map showing every single neuron and how they’re wired together in the brain of the fruit fly larva.

Researchers find methods to awaken and revive neural stem cells

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. A team led by scientists from the Universities of Geneva (UNIGE) and Lausanne (UNIL) has discovered the importance of cell metabolism in this process and identified how to wake up these neural stem cells and reactivate them. Biologists succeeded in increasing the number of new neurons in the brain of adult and even elderly mice. These results, promising for the treatment of neurodegenerative diseases, are to be discovered in the journal Science Advances.

Efficient and powerful biological computing harnesses brain organoids

According to Johns Hopkins University scientists, a “biocomputer” fueled by human brain cells could be created within this lifetime. Such technology is expected to tremendously enhance the capabilities of modern computing and develop novel fields of study.

New model, C. elegans, helps pursue research on Parkinson's disease

A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.

Scientists discover two ways to preserve diseased upper motor neurons in ALS

Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.

Study provides new insight into the brain circuits involved in opioid addiction

The ongoing opioid epidemic continues to take a heavy toll on American communities, with more than 80,000 opioid-related deaths reported in 2021, according to the National Institutes of Health.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

ApoE4 from neurons plays a critical role in Alzheimer's disease

Of all the known genetic risk factors for late-onset Alzheimer's disease, the strongest is a gene for the protein called ApoE4.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.

Study findings serve as a foundation for a thorough understanding of engram networks

Ensembles of synaptic networks are known to underlie cognitive functions, and the connections between engram neurons are enhanced during memory formation. Study from the researchers led by Prof. Bong-Kiun Kaang and Prof. Hye Yoon Park, identified the in vivo dynamics of synapses that underlie fear memory formation and extinction in living brains.

Scientists unravel the secrets of polydopamine coatings

Dopamine is best known as a neurotransmitter. What is rather unknown, however, the underwater glue used by mussels contains large amounts of L-Dopa molecules, an analog of dopamine.

DZNE scientists discover major role of centrosome in neuronal migration

Researchers from the DZNE have solved an important puzzle in neurobiology: the wiring and the movement of nerve cells are interwoven, but separately controlled.

New optical tool controls bacterial electrical signaling

Bacteria, like neurons in human brains, utilize electricity to interact and react to environmental cues. Scientists have now developed a strategy to regulate this electrical signaling in bacteria to better comprehend antibiotic resistance.

IGSF3-mediated potassium dysregulation drives glioma-related epilepsy

Glioma is one of the most aggressive malignant primary brain tumors. A common feature of glioma is the presence of localized, intermittent seizures referred to as glioma-related epilepsy, which is known to promote tumor growth. However, the mechanism involved at the molecular level is still not clear.
