The findings could make it easier to develop new treatments for the condition, in which loss can range from patches on the scalp to complete absence of hair on the entire body. Affecting approximately 5.3 million people, AA is the most common autoimmune disease in humans and is second only to male pattern baldness, when it comes to common forms of hair loss. There is no cure and no effective treatments, aside from painful steroid injections to the scalp that don't always work.
Dr. Angela Christiano, professor of dermatology and genetics and development at Columbia University Medical Center, was lead author of the study. She noted her team's discovery is important because it was originally thought that AA was more related to inflammatory diseases, such as psoriasis, where a particular cell attacks the skin. But during their research, Christiano and her investigators learned that AA is actually more genetically related to celiac disease, rheumatoid arthritis and type 1 diabetes – and since there are many drugs under development and some on the market already for the same gene targets, new treatments for AA should be relatively close by. That makes Christiano happy. Not only because her research will be helping millions of people, but she herself may benefit. She, too, suffers from AA.
"It gives us hope, that some day there may be a cure for this condition," she says. " It gives pharmaceutical companies a target to go forward and start developing new drugs to fight AA."
