WebDec 1, 2024 · Acute CPP crystal arthritis can be considered an auto-inflammatory disease. CPP crystals are recognised by the innate immune system as damage-associated molecular patterns (DAMPs), capable of activating the NLRP3 inflammasome-a molecular platform which, when stimulated, cleaves and expresses interleukin-1β (IL-1β) [7]. WebOct 10, 2024 · Calcium pyrophosphate (CPP) crystals (sometimes called pseudogout crystals) can become deposited on cartilage and various other tissues in and around joints.
