Table 2 Inflammatory diseases associated with inflammasome and related proteins
DiseaseInflammasome involvementReferences
Systemic onset juvenile arthritis (SoJIA)Human studies in patients with SoJIA showing: (1) increased expression of IL1β from PBMCs upon stimulation and (2) cases of clinical efficacy of recombinant IL1RaPascual et al, Verbsky et al82 93
Gout/CPPDDefective crystal-induced IL1β activation in knockout animals for NALP3, ASC or caspase-1; indirect evidence from human studies proving effectiveness of IL1Ra in goutMartinon et al, So et al4 81
Familial Mediterranean feverMutations of pyrin, an inflammasome inhibitor, may lead to defective downregulation of inflammasome activation or to direct activation of caspase-1Chae et al, The French FMF Consortium, The International FMF Consortium68 69 94 95
Cryopyrin associated periodic syndromes (CAPS)Mutated NALP3 (cryopyrin) has enhanced propensity to induce caspace-1Hoffman et al74
Crohn disease, Blau syndromeNOD2 mutations are identified in 10–15% of patients with Crohn disease: (1) Loss of function NOD2 mutations may lead to defective macrophage function, persistent intracellular infection of macrophages and chronic T cell stimulation; (2) gain of function NOD2 mutations may enhance the sensitivity of macrophages to MDP, thus potentiating NFκB activity and inflammatory responsesHugot et al, Oruga et al, Baumgart et al9698
  • ASC, apoptosis-associated speck-like protein containing a caspase recruitment domain (CARD); CPPD, calcium pyrophosphate dihydrate; IL, interleukin; IL1Ra, IL1 receptor antagonist; MDP, muramyl dipeptide; NALP, NTPases implicated in apoptosis and multihistocompatability complex transcription (NACHT) leucine-rich repeat protein; NFκB, nuclear factor κB; NOD, nucleotide-binding and oligomerisation domain.
