New MG Cell Model May Best Capture How Autoantibodies Affect Muscles in MG

Cell models that best mirror the surface of muscle cells crowded with acetylcholine receptors (AChR) are most helpful for understanding how self-reacting antibodies interrupt communication between nerve cells and muscles in myasthenia gravis (MG), a study reports. Using these models, researchers found that some antibodies only recognize clustered receptors,…

Immunoglobulin Helps by How It Acts on Regulatory T-Cells, Study Finds

Intravenous immunoglobulin (IVIg) works to treat people with myasthenia gravis (MG) by increasing the numbers of regulatory immune cells that help to control autoimmune reactions in the bloodstream, an early study suggests. A subset of these cells containing the CTLA-4 protein appears to be particularly important, and may provide…
