Answer

Urate crystals can engage an intracellular pattern recognition receptor, the macromolecular NALP3 (cryopyrin) inflammasome complex. [7, 8] NALP3 inflammasome may result in interleukin 1 (IL-1) beta production, which, in turn, incites an inflammatory response. Inhibition of this pathway has been targeted as a treatment for hyperuricemia-induced crystal arthritis, with recent reports documenting the efficacy of the IL-1 inhibitors canakinumab and rilonacept for preventing gout flares during the initiation of allopurinol therapy.
