Genetic mutations in PMP22 (peripheral myelin protein 22) cause a variety of peripheral neuropathies, underscoring the importance of the protein to a healthy peripheral nervous system. But the precise function of PMP22, a major component of the myelin sheath that surrounds and insulates peripheral nerve cell axons, has been unclear.

The identification of a genetic culprit for hypoplastic left heart syndrome could lead to new treatments for the condition.

In budding yeast, accumulation of a certain type of RNA in the nucleus increased life span, offering a new clue to longevity.

James Spudich, Ph.D., renowned for his studies of proteins that function as molecular motors, will deliver the next Flexner Discovery Lecture on Thursday, April 6.
