Mon, 19 Sep 2022 17:00:04 +0200 https://news.ki.se/reverse-strategy-finds-diagnostic-marker-of-autoimmune-disease Instead of searching for proteins that the immune system reacts against in a specific autoimmune disease, researchers have taken the opposite approach to find diseases linked to a certain protein. By searching among patients with various skin diseases, they identified a disease linked to autoimmunity against the skin protein TGM1. The strategy, which is presented in the journal PNAS, can facilitate the diagnosis and treatment of autoimmune diseases.
