Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

Advanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

Mitochondria‐Targeted Nanotherapeutics: A Promising Strategy in Modulating Mitochondrial Function, Transfer, and Transplantation

Advanced Science, EarlyView.
This review summarizes the pathogenic role of mitochondria in diseases and highlights mitochondrial transfer and transplantation as emerging therapeutic strategies. It systematically discusses how nanomaterials are engineered to facilitate these processes, and critically examines the current challenges and future perspectives for their clinical ...

Ryanodine receptor type 1 content decrease‐induced endoplasmic reticulum stress is a hallmark of myopathies

Journal of Cachexia, Sarcopenia and Muscle, 2023
Background Decreased ryanodine receptor type 1 (RyR1) protein levels are a well‐described feature of recessive RYR1‐related myopathies. The aim of the present study was twofold: (1) to determine whether RyR1 content is also decreased in other myopathies ...

Juvenile Idiopathic Inflammatory Myopathy at a developing Paediatric Rheumatology Clinic in Trinidad and Tobago: a case series

, 2023
Objective: Juvenile Idiopathic Inflammatory Myopathy (JIIM) is a rare autoimmune disorder with no published data from the English-speaking Caribbean. As such, we seek to produce the first dataset from Trinidad and Tobago on this condition.

Inflammatory Myopathy Associated with Anti-mitochondrial Antibody Presenting Only with Respiratory Failure

, 2021
A 56-year-old woman presenting with type II respiratory failure was transferred to our hospital. She did not exhibit muscle weakness or elevated serum myogenic enzymes, but needle electromyography revealed myogenic changes in the limb muscles, and her ...

Mechanically Regulated Secretion: How Physical Forces Instruct the Secretory Pathway and Remodel the Secretome

Advanced Science, EarlyView.
Mechanical cues, including ECM stiffness, stretch, compression, shear stress, and traction forces, remodel trafficking across the secretory pathway, from the ER and Golgi to endolysosomal compartments and the plasma membrane. The resulting secretome reshapes ECM composition and tissue mechanics, establishing feedback loops that support homeostasis or ...

Targeting necroptosis in muscle fibers ameliorates inflammatory myopathies

Nature Communications, 2022
Polymyositis (PM) is a chronic inflammatory myopathy characterized by progressive muscle weakness. Here the authors showed that muscle fibers in PM undergo necroptosis and aggravate inflammation via releasing pro-inflammatory molecules such as HMGB1.

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome

Annals of Neurology, EarlyView.
Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.

Amyloid myopathy mimicked with idiopathic inflammatory myopathy diagnosed using Congo red staining: a case report

BMC Neurology
Amyloid myopathy often occurs in the context of systemic amyloidosis, as a rare manifestation of “light chain” (AL) amyloidosis, accounting for 1% of its incidence.
