Repairing nerve cells after injury and in chronic disease

Each year in the United States there are more than 3 million cases of peripheral neuropathy, wherein nerves outside of the brain and spinal cord are damaged and cause pain and loss of feeling in the affected areas. Peripheral ...

New clues into the head-scratching mystery of itch

Scientists at Harvard Medical School have shown for the first time that a common skin bacterium—Staphylococcus aureus—can cause itch by acting directly on nerve cells.

New biomarker predicts whether neurons will regenerate

Neurons, the main cells that make up our brain and spinal cord, are among the slowest cells to regenerate after an injury, and many neurons fail to regenerate entirely. While scientists have made progress in understanding ...

Unlocking a secret nerve cell regenerator

Just like a gecko that regrows a broken tail, our peripheral nervous system knows how to regenerate the branches of its cells after an injury. Unfortunately, the cells in our central nervous system—our brain and spinal ...

Researchers uncover signal needed for blood-brain barrier

What makes the vital layer of protective cells around the brain and spinal cord—the blood-brain barrier—more or less permeable has been one of the more mystifying questions in neuroscience.
