Can a newly discovered enzyme reshape autoimmune disease treatment?

Myasthenia gravis (MG) is a chronic autoimmune disorder where antibodies block nerve-muscle communication. Like many other autoimmune conditions, these diseases result from improper regulation of IgG antibodies and are known as IgG-mediated pathologies. Based on a mouse model study, researchers at Emory University reveal a family of enzymes, particularly one called CU43, that can reduce the impact of these harmful antibodies in diseases like MG.

The enzyme, CU43, was shown to be particularly effective in treating autoimmune diseases caused by overactive IgG antibodies. When tested on mice, this enzyme performed significantly better than current MG treatments, requiring 4,000 times less of the enzyme to achieve the same therapeutic effect. This suggests a potential for fewer side effects and more flexible drug administration methods, making it a promising alternative to current treatments for MG and similar autoimmune disorders.

The research team is optimistic about the clinical potential of this enzyme. With its impressive efficacy in mice, they hope to quickly transition to human trials to explore its use for a broader range of autoimmune diseases and IgG-mediated conditions. This discovery could revolutionize treatment for such disorders, offering a more potent and lower-dose option to patients.

The Autoimmune Registry recently partnered with Own MG, a nonprofit organization dedicated to improving the lives of individuals affected by myasthenia gravis, a rare autoimmune disorder. Join our webinar with Own MG today, October 23rd from 12-1 pm Eastern via Zoom.
