Medical News Today reports: Researchers from the University of Alabama at Birmingham (UAB) have discovered a new immune protein [Fc receptor] influencing autoimmune diseases such as lupus and multiple sclerosis…
The Fc receptor regulates the production of antibodies that attack bacteria in our bodies. Previously, scientists thought that Fc receptors could only shut down antibody production, but about 15% of the world's population have this new kind of Fc receptor that can also activate antibody production. In people with lupus, this means that the Fc receptor would create too many antibodies, resulting in an attack on healthy cells.
Being able to identify this receptor mutation in patients could help doctors prescribe treatments specific to that patient, and it could also provide early warning signs of autoimmune disease.
