A new murine model of myasthenia gravis that is more effective and better suited to animal welfare

The Myasthenia gravis, etiology, pathophysiology & therapeutical approaches team, led by Rozen Le Panse at the Institute of Myology’s Myology Research Centre, has developed a new experimental murine model of myasthenia gravis (N-EAMG) that is at least as effective as the classic experimental model (C-EAMG) and offers several advantages. N-EAMG:

  • is better suited to animal welfare,
  • is characterised by the production of T-AChR and m-AChR antibodies, like C-EAMG,
  • also has altered transmission in the NMJ,
  • presents symptoms similar to those observed in C-EAMG, but with a more rapid onset.

This model can replace the classical model in preclinical and fundamental research.
