CCR6 and systemic sclerosis: In the skin of SSc patients, CCR6 expression was significantly increased in dermal small vessels and keratinocytes as compared to those cells of healthy control skin (2 [2–2.8] versus 1 [0.5–1.5], p = 0.022; 2.0 [2.0–3.0] versus 1.0 [1.0–2.0], p = 0.0089; respectively), while comparable in dermal fibroblasts and inflammatory cells.
