CD2 expressing innate lymphoid and T cells are critical effectors of immunopathogenesis in hidradenitis suppurativa.

Proc Natl Acad Sci U S A

Center for Epigenomics and Translational Research in Inflammatory Skin Diseases, University of Alabama at Birmingham, Birmingham, AL 35294.

Article Synopsis
  • Hidradenitis suppurativa (HS) is identified as a chronic inflammatory skin disease characterized by an increase in CD2-expressing lymphocytes and T cells in affected skin areas.
  • CD2+ cells, primarily innate lymphocytes and CD4 T cells, interact with keratinocytes and fibroblasts, highlighting their role in the disease's unique skin dynamics.
  • Blocking the CD2:CD58 interaction may reduce inflammation and suggests a promising immunotherapeutic strategy for managing HS.

In 1997 rituximab, a genetically engineered chimeric monoclonal antibody (mAb) targeting CD20 expressed on B cells was approved for treatment of non-Hodgkin's lymphoma. Since then, pharmacological improvements combined with increased knowledge on the immunopathogenesis of diseases led to the development of specific mAb targeting different antigens (e.g.

Article Synopsis
  • The management of pediatric dermatological conditions has advanced with new biologics and small molecule therapies, originally approved for adults but now being evaluated for children and adolescents.
  • The review aims to summarize recently FDA-approved and potential therapies for conditions like alopecia areata, psoriasis, atopic dermatitis, and hidradenitis suppurativa in pediatric patients.
  • Key findings include FDA-approved treatments such as ritlecitinib for alopecia areata and multiple biologics for pediatric psoriasis and atopic dermatitis, with several others undergoing phase 3 clinical trials for potential approval.

The immunopathogenesis of HS is partially understood and exhibits features of an autoinflammatory disease; it is associated with the potential involvement of B cells and the contribution of Th1 or Th17 cell subsets. Recently, the pathogenic role of both innate immunity and IL-1 family cytokines in HS has been deeply investigated. Several agents targeting the IL-1 family pathway at different levels are currently available and under investigation for the treatment of HS.
