Lower frequencies of circulating suppressive regulatory T cells and higher frequencies of CD4+ naïve T cells at baseline are associated with severe immune-related adverse events in immune checkpoint inhibitor-treated melanoma

Kovacsovics-Bankowski & Sweere. JITC (2024)

Publication Highlights

  • CD4+ naïve T cells, CD16+ natural killer (NK) cells and T cell immunoreceptor with Ig and ITIM domain (TIGIT)+ regulatory T cells (Treg) cells are present at significantly different frequencies in the peripheral blood before ICI-treatment in patients with severe irAE compared with patients without severe irAE, and that peak of severe irAE is associated with activated CD4+ and CD8+ memory T cells.
  • These immune features are not associated with BRAF mutation status and are generally observed across different irAE categories
  • Patients with severe irAE were more likely to observe clinical benefit from ICI, and patients with clinical benefit also had significantly different frequencies of CD4+ naive T cells, CD16+ NK cells and suppressive Treg at baseline compared with patients without clinical benefit.
