Muscle homeostasis involves de novo myogenesis, as observed in conditions of acute or chronic muscle damage. Tumor Necrosis Factor (TNF) triggers skeletal muscle wasting in several pathological conditions and inhibits muscle regeneration. We show that intramuscular treatment with the myogenic factor Arg(8)-vasopressin (AVP) enhanced skeletal muscle(More)
STIMs (STIM1 and STIM2 in mammals) are transmembrane proteins that reside in the endoplasmic reticulum (ER) and regulate store-operated Ca(2+) entry (SOCE). The function of STIMs in the brain is only beginning to be explored, and the relevance of SOCE in nerve cells is being debated. Here we identify STIM2 as a central organizer of excitatory synapses.(More)
How a cell decides to self-renew or differentiate is a critical issue in stem cell and cancer biology. Atypical protein kinase C (aPKC) promotes self-renewal of Drosophila larval brain neural stem cells, neuroblasts. However, it is unclear how aPKC cortical polarity and protein levels are regulated. Here, we have identified a zinc-finger protein, Zif, which(More)
Recent findings point to a central role of the endoplasmic reticulum-resident STIM (Stromal Interaction Molecule) proteins in shaping the structure and function of excitatory synapses in the mammalian brain. The impact of the Stim genes on cognitive functions remains, however, poorly understood. To explore the function of the Stim genes in learning and(More)
Common variable immunodeficiency (CVID), a frequent primary immunodeficiency disease, is characterized, by defects involving T and B cells. The Aiolos transcription factor plays an important role in the control of B cell differentiation and proliferation and is modulated through alternative splicing. In order to assess the role of Aiolos in this human(More)
Peripheral Facial palsy (PFP) is generally considered a benign condition with good recovery and no sequelae. Yet, a distortion in the gesture and abnormal blinking, as those typically found in blepharospasm, can potentially develop early on. Such abnormal movements seem to be related to remodelling mechanisms that take place in the process of recovery. We(More)
AIMS The aim of this study was to review the value of neurophysiological exploration in peripheral facial paralysis in the literature and in our own experience. METHOD Peripheral facial paralysis is a frequently occurring cranial neuropathy with an acute presentation. Its striking clinical expression is usually in strong contrast to its benign prognosis,(More)
