A previous study included subjects with JIA uveitis, JIA without eye involvement, idiopathic anterior uveitis, and healthy children (n = 18, 11, 12, and 11, respectively) and concluded that frequency of interleukin (IL)-13-expressing cells and IL-13 and IL-10 expression levels were elevated in all patient subgroups, while percentages of IL-5-expressing T cells were diminished. Here, IL13 is linked to uveitis.
