The neuromuscular junction disorders.
Neuromuscular junction (NMJ) disorders result from destruction, malfunction or absence of one or more key proteins involved in neuromuscular transmission, illustrated diagrammatically in fig 1. The most common pathology is antibody mediated damage or down regulation of ion channels or receptors, resulting in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), and acquired neuromyo...
متن کاملAutoimmune disorders of the neuromuscular junction.
The neuromuscular junction lies beyond the protection of the blood-brain barrier and is particularly vulnerable to antibody-mediated attack. In myasthenia gravis, the expression of acetylcholine receptors (AChRs) in the thymus is under the control of the autoimmune regulator protein (AIRE), and polymorphisms in the AChR correlate with early onset of disease. In some 'AChR seronegative' patients...
متن کاملMyasthenia gravis and other neuromuscular junction disorders.
Correspondence to: Dr Saiju Jacob, Department of Neurology, Queen Elizabeth Neurosciences Centre, University Hospitals of Birmingham, B15 2TH, UK; [email protected] Myasthenia gravis is the most common autoimmune disease affecting the neuromuscular junction and is characterised by painless fatigable muscle weakness. It is caused by autoantibodies against neuromuscular junction proteins, eithe...
متن کاملElectrophysiological recordings from the neuromuscular junction of C. elegans.
Electrophysiology provides a quantifiable measure of synaptic activity useful in the functional analysis of synaptic proteins. Recent advances in the application of this technique to C. elegans provides a means of coupling genetics to electrophysiological analysis, providing new insights into the molecular mechanisms regulating neurotransmission. Here we describe a dissection technique that exp...
متن کاملPitfalls in Using Electrophysiological Studies to Diagnose Neuromuscular Disorders
Electrodiagnostic testing is used widely for the full characterization of neuromuscular disorders and for providing unique information on the processes underlying the pathology of peripheral nerves and muscles. However, such testing should be considered as an extension of anamnesis and physical examination, not as pathognomonic of a specific disease entity. There are many pitfalls that could le...
