Autoimmunity is a process by which the immune system reacts against the body's own tissues. Chronic and/or excessive autoimmune responses can result in autoimmune diseases.
Previous studies have reported heterogeneity in the progression to clinical type 1 diabetes in children who develop either insulin- or glutamic acid decarboxylase-specific antibodies as their first autoantibodies. Here, the authors show that children who later develop disease have distinct characteristics in early immune responses, which are dependent on the type of autoantibodies that appear first.
In this Review, the authors analyze evidence for autoimmunity against components of antimicrobial immunity, metaphorically represented by the mythical ouroboros snake eating its own tail.
Multidimensional and single-cell profiling of peripheral blood and inflamed tissues is a powerful and high-resolution tool for the stratification of patients with autoimmune rheumatic diseases into distinct cellular and/or molecular endotypes. The road towards precision rheumatology is long, but the time has come to enter the territory of clinical validation.
Autoantibodies that develop in systemic lupus erythematosus (SLE) can cause long-term cognitive impairment that remains even after the systemic disease becomes quiescent. This study attributes the persistent cognitive symptoms of SLE to a self-sustaining neuroinflammatory process that continues indefinitely unless disrupted — which can be done using medications approved by the US Food and Drug Administration.
