Reduced expression of inflammasome complex components in cluster headache

Abstract

The involvement of inflammation in the pathophysiology of cluster headache (CH) has been suggested, with a role implied for interleukin (IL)‐1β. We aimed to measure peripheral blood expression levels of IL‐1β–inducing systems, the inflammasome complex, and nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB) signaling, and investigate their values as putative biomarkers in CH.
