Neural S1PR3 Receptor Boosts Resilience To Stress

A receptor on the surface of brain cells plays a key role in regulating how both animals and people respond to stress, scientists have discovered. The research suggests that the receptor may represent an important biomarker of post-traumatic stress disorder (PTSD) in humans and may offer a new target for future, more effective treatments for […]

How Transcriptomics Is Changing How We Think About Brain Cells

Neurons, the fundamental component of the nervous system, exist in a multitude of forms and types. There may be as many as 10,000 specific types of neurons in the human brain. There is even a type of cell discovered in 2005 known as the “Jennifer Aniston neuron” that specifically responds to images of well-known celebrities […]

Researchers Identify Key Proteins For The Repair Of Nerve Fibers

A group of proteins that help to regenerate damaged nerve cells has been identified by scientists at the German Center for Neurodegenerative Diseases (DZNE). It is commonly accepted that neurons of the central nervous system shut down their ability to grow when they no longer need it; this occurs normally after they have found their […]

Activin A, Follistatin May Be Key To Restore Damaged Sound-detecting Cells In The Ear

Using genetic tools in mice, researchers at Johns Hopkins Medicine say they have identified a pair of proteins that precisely control when sound-detecting cells, known as hair cells, are born in the mammalian inner ear. The proteins may hold a key to future therapies to restore hearing in people with irreversible deafness. “Scientists in our […]

Why Strength Training Might Come At The Expense Of Endurance Muscles

The neurotransmitter brain-derived neurotrophic factor (BDNF) is produced by the muscle and acts on both muscles and synapses, researchers at the University of Basel’s Biozentrum have found. In their recent work, Prof. Christoph Handschin’s research group at the Biozentrum closely studied strength muscles and the myokine BDNF, which plays an important role in the formation […]
