Identification of IL-33 in Dendritic Cells and its Impact on Treg Populations

IL-33, initially associated with barrier cytokine released upon tissue damage, was found to be produced by dendritic cells rather than epithelial cells. This discovery challenged existing hypotheses, revealing IL-33's critical role in shaping T cell responses. IL-33 in dendritic cells is delivered to regulatory T cells via perforin 2, contributing to their suppressive nature and enhancing their proliferative capacity.
