To evaluate levels of the calcium-binding proteins S100A8 and S100A9 in the skin of patients with psoriatic arthritis.
Skin punch biopsies were obtained from patients with psoriatic arthritis and healthy control subjects. S100A8/A9 were semiquantified via immunohistochemistry and semiquantitative polymerase chain reaction.
The study included biopsies from nine patients with psoriatic arthritis and nine control subjects. S100A8 and S100A9 were present at visibly higher levels in psoriatic plaques compared with normal skin samples. S100A8 and S100A9 RNA levels were significantly higher in the peripheral region of plaques compared with the central region.
Both S100A8 and S100A9 may represent good therapeutic targets in psoriasis and psoriatic arthritis.
评估银屑病关节炎患者皮肤中钙结合蛋白S100A8和S100A9的水平。
从银屑病关节炎患者和健康对照者身上获取皮肤打孔活检样本。通过免疫组织化学和半定量聚合酶链反应对S100A8/A9进行半定量分析。
该研究纳入了9例银屑病关节炎患者和9例对照者的活检样本。与正常皮肤样本相比,银屑病斑块中S100A8和S100A9的水平明显更高。与斑块中央区域相比,斑块周边区域的S100A8和S100A9 RNA水平显著更高。
S100A捌和S100A9可能都是银屑病和银屑病关节炎良好的治疗靶点。
