Description
Per Stal and co-authors report in 2026 that a key muscle protein is missing from some fibers in head and neck muscles. Desmin is a building protein long thought to appear in every mature muscle fiber.
The team checked twenty one adult head and neck muscles, plus toddler and fetal samples, with stained tissue views. Two limb muscles served as controls, and every fiber there showed the protein. In head and neck muscles, by contrast, some fibers in every muscle lacked the protein or showed it only weakly. Those fibers were mostly of the slow type. Gene message tests in one muscle group matched the pattern, which reveals hidden variety in these muscles.
