During the initial stage of neuromuscular junction (NMJ) formation, nerve-derived agrin cooperates with muscle-autonomous mechanisms in the organization and stabilization of a plaque-like postsynaptic specialization at the site of nerve-muscle contact. Subsequent NMJ maturation to the characteristic pretzel-like appearance requires extensive structural(More)
Etiology and pathogenesis of sarcopenia, the progressive decline in skeletal muscle mass and strength that occurs with aging, are still poorly understood. We recently found that overexpression of the neural serine protease neurotrypsin in motoneurons resulted in the degeneration of their neuromuscular junctions (NMJ) within days. Therefore, we wondered(More)
BACKGROUND Giant cell arteritis is an immune-mediated disease of medium and large-sized arteries that affects mostly people older than 50 years of age. Treatment with glucocorticoids is the gold-standard and prevents severe vascular complications but is associated with substantial morbidity and mortality. Tocilizumab, a humanised monoclonal antibody against(More)
