Current Concepts in Acne Pathogenesis: Pathways to Inflammation

Semin Cutan Med Surg. 2018 Jun;37(3S):S60-S62. doi: 10.12788/j.sder.2018.024.

Abstract

Acne is a disease of pilosebaceous inflammation. Pivotal in pathogenesis are the roles of hormones (insulin, insulin-like growth factor-1, androgens), Propionibacterium acnes, lipogenesis, and a proinflammatory lipid profile. Innate immune responses are induced through interaction with toll-like receptors and inflammasome activation initially and subsequently through adaptive immune activation. These insights into pathogenic inflammatory pathways can translate into novel therapeutic approaches for acne.
