Mechanism of Disease


Not an actual patient. Individual results will vary. 

IL-1β is a critical driver of autoinflammatory disease1-4 

Autoinflammatory diseases have a different pathogenic profile than autoimmune diseases1-6

Autoinflammatory Diseases Autoimmune Diseases
Key drivers: IL-1 β, IL-6, IL-18, and TNFKey drivers: 1FN-y and IL-17

IL-1β is primarily induced and actively produced by immune cells under disease conditions7,8

Diagram showing the Ilaris mechanism of disease for periodic fever syndromes.

In certain autoinflammatory diseases, there is an excessive release of activated 1L-1β.2,4,9,10

This overabundance can1,2,4,8-10:

  • Cause an inflammatory cascade 
  • Trigger a feedback loop, inducing the production of even more IL-1β 

The inflammatory cascade in PFS can drive fever and systemic inflammation1,4,11-12
