Hidradenitis Suppurativa: An Exploration of Genetic Perturbations and Immune Dysregulation
Hidradenitis suppurativa (HS) is a chronic, inflammatory skin condition that poses a significant diagnostic and therapeutic challenge for clinicians, as the underlying etiology and pathogenesis remains unclear. The host of genetic mutations and immune dysfunction has been identified to be involved in the pathogenesis of HS during recent years. These genetic defects, including monogenetic mutations altering subunits of γ-secretase, a protease that functions through Notch signaling to maintain skin appendages, promote epithelial stability, suppress/terminate innate immune responses (ie, Toll-receptors), further have the propensity to induce aberrant cytokine responses that create to a proinflammatory environment, consequently induce hyperkeratosis and promote expression of pro-inflammatory, locally destructive matrix metalloproteinases. Cytokine-driven inflammation propagates the disease state of HS and contributes to the formation of painful subcutaneous nodules, abscesses, and eventually, fistulas and draining sinus tracts. A closer look at genetic mutations linked to the disease may explain the immune perturbations seen in HS. An understanding of the immune cells and inflammatory markers expressed in affected individuals provides insight into disease pathogenesis and can help identify therapeutic targets.
