Abstract

Mast cells, key effector cells of allergic and innate immune responses, have recently been reported to be an important source of IL-1s in patients with autoinflammatory conditions such as cryopyrin-associated-periodic-fever syndromes (CAPS). CAPS patients show IL-1beta-driven systemic inflammation together with non-histamine dependent urticarial rash, which are caused by activating mutations of the inflammasome, a multiprotein oligomer responsible for the initiation of inflammatory responses to pathogens.

Highlights

  • Mast cells, key effector cells of allergic and innate immune responses, have recently been reported to be an important source of IL-1ß in patients with autoinflammatory conditions such as cryopyrin-associated-periodic-fever syndromes (CAPS)

  • OR11-005 - Mast cells respond to pathogen signals with IL-1ß

  • To determine if mast cells can produce and release IL-1ß in response to pathogenic signals that target the inflammasomes NLRP3, NLRC4, or AIM2
