Special Issue Information
Dear Colleagues,
Skeletal muscle atrophy is a condition common to disuse, immobilization, injury, trauma, disease and aging. Atrophy can be an extremely fast process that can be detected after just 3 days of muscle unloading in healthy humans. Many clinical conditions involving inflammation and oxidative stress exacerbate muscle wasting and, when associated with the loss of muscle mass occurring with ageing (sarcopenia), lead to frailty and loss of independence. Yet, the molecular mechanisms responsible for muscle atrophy in many neuromuscular disorders, such as amyotrophic lateral sclerosis (ALS), spinal muscle atrophy (SMA), multiple sclerosis (MS), muscular dystrophy (MD), myasthenia gravis (MG), myopathies, neuropathies, etc., as well as in aging and inactivity, are to be fully understood. The paucity of knowledge also exists on the efficacy of the physical, nutritional and pharmacological intervention on the recovery of muscle loss in most neuromuscular disorders and aging. Even in healthy young adults, chronic inactivity seems to trigger neuropathic processes causing instability of the neuromuscular junction, axonal damage and denervation/reinnervation of muscle fibres.
This Special Issue will review the current knowledge on the mechanisms of muscle atrophy with disuse, inactivity, aging and with some of the most relevant neuromuscular disorders and discuss the effect of conventional but also innovative therapeutic interventions in the prevention/recovery of muscle mass and strength loss associated with these conditions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
