"Skin Sodium Accumulates in Psoriasis and Reflects Disease Severity" (Maifeld et al., 2021) showed that skin sodium ion (Na) is increased in patients with a PASI > 5. Na concentration as well as its content were increased in these patients, supporting the proposed mechanism that increased Na concentrations enhance IL-17 expression from CD4 cells. These data initially were generated using a noninvasive technique, sodium (Na) magnetic resonance imaging, and then were verified using Na spectroscopy and atomic absorption spectrometry in ashed-skin biopsies in humans and also using mouse models of psoriasis. These findings suggest a novel pathologic mechanism for psoriasis development and target for treatment.
“银屑病患者皮肤钠离子蓄积且与疾病严重程度相关”(Maifeld 等,2021)表明,PASI>5 的患者皮肤钠离子(Na)增加。这些患者的 Na 浓度及其含量均增加,支持了这样一种提出的机制,即增加的 Na 浓度增强了 CD4 细胞的 IL-17 表达。这些数据最初是使用非侵入性技术——钠离子(Na)磁共振成像获得的,然后在人类的皮肤活检组织经灰化处理后使用 Na 光谱法和原子吸收光谱法以及银屑病的小鼠模型进行了验证。这些发现提示了银屑病发病的新病理机制和治疗靶点。
