Researchers hunt for clues: do our own antibodies harm nerves?

This study looks at whether the immune system mistakenly makes antibodies that attack the body's own nerves and muscles in people with multiple sclerosis, myasthenia gravis, and similar conditions. Researchers will collect blood samples (and sometimes cheek swabs) from 120 adults over up to 3 years to track these antibodies. The goal is to understand how these antibodies might contribute to disease, not to treat or diagnose any condition.
