THE PATHOLOGY OF GPP
THE IL-36 PATHWAY PLAYS A KEY ROLE IN THE PATHOGENESIS OF GPP1
GPP IS DRIVEN BY THE IL-36 PATHWAY1
IL-36 agonists bind to the IL-36 receptor, or IL-36R, on keratinocyte surfaces, promoting IL-36 expression. This pathway regulates the expression of numerous cytokines, triggering a pro-inflammatory cycle.1,2

THE IL-36 PATHWAY IS REGULATED BY THE INTERPLAY BETWEEN IL-36 AGONISTS AND ANTAGONISTS3,4
Any imbalance between IL-36 agonists and antagonists causes dysregulation in the IL-36 pathway. Unregulated IL-36R signalling leads to uncontrolled induction of downstream inflammatory cytokines, which play a key role in the pathogenesis of GPP.1,2,5
