    Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with complex pathophysiology involving immune and stromal cells.

  • 2

    CD4+ central memory T cells (TCM) are significantly expanded in HS lesions compared to healthy skin, indicating altered immune dynamics.

  • 3

    A positive correlation exists between skin-infiltrating TCM levels and those in systemic circulation among HS patients.

  • 4

    CD4+ resident memory T cells (TRM) are significantly depleted in HS lesions, suggesting potential phenotypic changes during chronic inflammation.

  • 5

    Skin-derived memory T cells in HS exhibit a hyper-responsive phenotype, producing higher levels of key cytokines than matched peripheral blood mononuclear cells.
