https://www.selleckchem.com/products/jnj-64264681.html Z-band alternatively spliced PDZ-motif protein (ZASP) is a sarcomeric component expressed both in cardiac and skeletal muscles. Mutations in the LDB3/ZASP gene cause cardiomyopathy and myofibrillar myopathy. We describe a c.76C>T / p.[Pro26Ser] mutation in the PDZ motif of LDB3/ZASP in two siblings exhibiting late-onset myopathy with axial, proximal and distal muscles involvement and marked variability in clinical severity in the absence of a significant family history for neuromuscular disorders. Notably, we identified involvement of the psoas muscle on MRI and muscle CT, a feature not previously documented. Proband's muscle biopsy showed an increase of ZASP expression by western blotting. Muscle fibres morphological features included peculiar sarcolemmal invaginations, pathological aggregates positive to ZASP, ubiquitin, p62 and LC3 antibodies, and the accumulation of autophagic vacuoles, suggesting that protein aggregate formation and autophagy are involved in this additional case of zaspopathy.The Corona Virus Disease (COVID-19) pandemic caused by Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) requires a rapid solution and global collaborative efforts in order to define preventive and treatment strategies. One of the major challenges of this disease is the high number of patients needing advanced respiratory support due to the Acute Respiratory Distress Syndrome (ARDS) as the lung is the major - although not exclusive - target of the virus. The molecular mechanisms, pathogenic drivers and the target cell type(s) in SARS-CoV-2 infection are still poorly understood, but the development of a "hyperactive" immune response is proposed to play a role in the evolution of the disease and it is envisioned as a major cause of morbidity and mortality. Here we propose a theory by which the main targets for SARS-CoV-2 are the Type II Alveolar Epithelial Cells and the clinical manifestations of the syndrome
