One of the alterations that most affects the quality of life of the elderly is muscle wastage and the resulting loss of strength, a condition known as sarcopenia. At about 55 years old, people begin to lose muscle mass, this loss continues into old age, at which point it becomes critical. The underlying causes of sarcopenia are unknown and thus no treatment is available for this condition.
A new study has discovered that Mitofusin 2 is required to preserve healthy muscles in mice. In the paper, which has been published today in The EMBO Journal, these researchers indicate that this protein could serve as a therapeutic target to ameliorate sarcopenia in the elderly.
