2、is reason the term autoinflammatory is preferable to autoimmune in describing these disorders.”“Germline mutations in the extracellular domains of the 55 kDa TNF receptor,TNFR1,define a family of dominantly inherited autoinflammatory syndromes.”McDermott,et al.,Cell.1999 Apr 2;97(1):133-44.4自身免疫性炎症综

3、合症“Autoinflammatory”DiseaseAt the time,autoinflammatory was coined to distinguish diseases involving innate immune dysregulation(FMF&TRAPS)from autoimmune diseases known to involve adaptive immune dysregulation(SLE&RA).Two premises of autoimmune disease are unfulfilled in autoinflammatory disorders:

4、1.The inflammation is seemingly“unprovoked”.2.Autoantibodies and antigen-specific T cells are absent.5自身免疫性炎症综合症6自身免疫性炎症综合症7自身免疫性炎症综合症8自身免疫性炎症综合症9自身免疫性炎症综合症CytokineDisease GeneProteinInherit.patternDisease onsetFever patternSpecific organ inflammationIL-1b bCAPSFCASMWSCIAS1CIAS1CIAS1CryopyrinCryopyr
