Traditionally, CD4+ T cells have been separated into two different subsets named T helper
(Th) 1 and Th2. A new IL-23–driven subset of Th cells called ThIL-17 has now been
described. The data suggest that IL-23 plays an important role in the differentiation of
autoreactive pathogenic T cells. Whether these IL-23–induced ThIL-17 cells are a unique
subset or are related to other Th subsets is discussed.
