Kawasaki disease
Debate has occurred about whether Kawasaki disease should be viewed as a characteristic immune response to some infectious pathogen, as an autoimmune process, or as an autoinflammatory disease (i.e. involving innate rather than adaptive immune pathways). Overall, immunological research suggests that Kawasaki disease is associated with a response to a conventional antigen (rather than a superantigen) that involves both activation of the innate immune system and also features of an adaptive immune response. Identification of the exact nature of the immune process involved in Kawasaki disease could help guide research aimed at improving clinical management.
