Researchers discover ceramides role in aging muscle health

Like people, mice lose strength and muscle mass as they age and become less active. Now, it has been discovered by a group of researchers at EPFL, led by Johan Auwerx, that as mice get older, their muscles fill up with ceramides. Ceramides are sphingolipids, a family of fat molecules that serve a variety of functions in the cell rather than generating energy and are well-known for their use in skin care products.
