Anti-Ro/SSA antibodies

Anti-Ro/SSA antibodies are special proteins made by the immune system that mistakenly target parts of the body's own cells, specifically molecules called Ro/SSA proteins. Their presence is often associated with autoimmune diseases like Sjögren's syndrome and lupus, where the immune system attacks the body's moisture-producing glands and other tissues. Detecting these antibodies helps doctors diagnose and understand these conditions. While their exact role isn't fully understood, their presence indicates immune system activity against certain cell components, contributing to disease symptoms and progression.
