Introduction to the Special Issue “Skeletal Muscle Atrophy: Mechanisms at a Cellular Level”

Abstract

Skeletal muscle is the most abundant tissue in the body and requires high levels of energy to function properly. Skeletal muscle allows voluntary movement and body posture, which require different types of fiber, innervation, energy, and metabolism. Here, we summarize the contribution received at the time of publication of this Introductory Issue for the Special Issue dedicated to “Skeletal Muscle Atrophy: Mechanisms at a Cellular Level”. The Special Issue is divided into three sections. The first is dedicated to skeletal muscle pathophysiology, the second to disease mechanisms, and the third to therapeutic development.
