[Myasthenia gravis. Prototype of an anti-receptor autoaggression disease (author's transl)]
Abstract:
Myasthenia gravis is a classic autoaggression disease in which autoantibodies against the acetylcholine receptors (AChR) of the neuromuscular end-plate have a decisive patho-genetic significance. With sensitive radioimmunoassays anti-AChR antibodies are demonstrable in over 90% of myasthenics and consequently are of great diagnostic significance. The treatment possibilities to date have distinctly improved the prognosis but are either symptomatic or unspecific. More recent knowledge on pathophysiology and pathogenesis and the strategies for development of a specific immunotherapy deducible from this are discussed. X

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
Myasthenia Gravis: Overview and Treatment
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...
