Updates on autoinflammatory diseases

Autoinflammatory diseases are hyperinflammatory, immune dysregulatory diseases caused by innate immune cells dysregulation that present typically in the perinatal period with systemic and organ-targeted inflammation, but with improved genetic testing and the development of diagnostic criteria, milder and later-onset forms are being detected in adulthood. While the discovery of gain-of-function mutations in innate sensors linked to the production of proinflammatory cytokines provided the bases for anti-cytokine therapies that changed disease and patient outcomes, the field is expanding with the increasing discovery of disease-causing loss-of-function mutations in genes with cellular house-keeping functions that affect cell homeostasis and when dysregulated trigger innate inflammatory pathways. This review focuses on updates on molecular pathways and diseases that cause predominantly IL-1β and Type-I IFN-mediated autoinflammatory diseases.
