  2. Myasthenia gravis - Wikipedia

    en.wikipedia.org/wiki/Myasthenia_gravis

    Myasthenia gravis is an autoimmune disease of the neuromuscular junction which results from antibodies that block or destroy nicotinic acetylcholine receptors (AChR) at the junction between the nerve and muscle. [6][7][1] This prevents nerve impulses from triggering muscle contractions. [1]

  3. Acetylcholine receptor - Wikipedia

    en.wikipedia.org/wiki/Acetylcholine_receptor

    In myasthenia gravis, the receptor at the neuromuscular junction is targeted by antibodies, leading to muscle weakness. Muscarinic acetylcholine receptors can be blocked by the drugs atropine and scopolamine. Congenital myasthenic syndrome (CMS) is an inherited neuromuscular disorder caused by defects of several types at the neuromuscular ...

  4. Autoimmune autonomic ganglionopathy - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_autonomic...

    Autoimmune autonomic ganglionopathy is a type of immune-mediated autonomic failure that is associated with antibodies against the ganglionic nicotinic acetylcholine receptor present in sympathetic, parasympathetic, and enteric ganglia. Typical symptoms include gastrointestinal dysmotility, orthostatic hypotension, and tonic pupils. [1]

  5. Lambert–Eaton myasthenic syndrome - Wikipedia

    en.wikipedia.org/wiki/Lambert–Eaton_myasthenic...

    Myasthenia gravis is caused by autoantibodies to the postsynaptic acetylcholine receptors. Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder characterized by muscle weakness of the limbs. It is also known as myasthenic syndrome, Eaton–Lambert syndrome, and when related to cancer, carcinomatous myopathy.

  6. Neuromuscular junction disease - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction_disease

    Transient neonatal myasthenia gravis is a very rare condition in which a mother with myasthenia gravis passes down her myasthenia gravis-inducing antibodies to her fetus through the placenta, causing the fetus to be born with antibodies that attach to self-antigens at the neuromuscular junction.(reference 12) Most cases of transient neonatal ...

  7. Ocular myasthenia - Wikipedia

    en.wikipedia.org/wiki/Ocular_myasthenia

    Ocular myasthenia. Ocular myasthenia gravis (MG) is a disease of the neuromuscular junction resulting in hallmark variability in muscle weakness and fatigability. MG is an autoimmune disease where anomalous antibodies are produced against the naturally occurring acetylcholine receptors in voluntary muscles. MG may be limited to the muscles of ...
