一些但不是全部特应性皮炎 (AD) 患者出现过敏性结膜疾病 (ACD),包括严重类型,例如伴有/不伴有巨大乳头的特应性角结膜炎 (AKC)。我们假设 ACD 和 AD 的严重程度涉及不同的因素。最近我们报道 hsa-miR-628-3p 可以通过抑制 Toll 样受体 3 (TLR3)、RIG-I 和 MDA-5 等病原体相关分子模式来影响先天免疫的平衡。我们还报道,TLR3 正向调节眼表和皮肤炎症,如接触性皮炎和 AD。在这里,我们将患有严重 AKC(伴有巨大乳头和/或盾状溃疡)的 AD 患者中 miR-628-3p 的血浆水平与健康对照和无 AKC 或非常轻度 AKC 的 AD 患者的血浆水平进行了比较。我们使用了 32 名患有严重 AKC 的 AD 患者、40 名健康对照者和 23 名没有 AKC 或患有非常轻微的 AKC 且没有巨大乳头或盾状溃疡的 AD 患者的血浆。使用定量 microRNA PCR 检测来测量他们的血浆 miR-628-3p 水平。我们发现血浆 miR-628-3p 在伴有严重 AKC 的 AD 中上调,但在不伴有严重 AKC 的严重 AD 中没有上调,在我们的健康对照中也没有上调。我们的新发现表明,血浆 miR-628-3p 水平可能是预测 AD 患者是否存在严重 AKC 的标志物。
Some but not all patients with atopic dermatitis (AD) present with allergic conjunctival disease (ACD) including severe types such as atopic keratoconjunctivitis (AKC) with/without giant papillae. We hypothesized that different factors are involved in the severity of ACD and AD. Recently we reported that hsa‐miR‐628‐3p could affect the balance of innate immunity by suppressing pathogen‐associated molecular patterns such as toll‐like receptor 3 (TLR3), RIG‐I, and MDA‐5. We also reported that TLR3 positively regulates ocular surface‐ and skin inflammation such as contact dermatitis and AD. Here we compared the plasma level of miR‐628‐3p in AD patients with severe AKC with giant papillae and/or shield ulcers, with the level in healthy controls and AD patient without AKC or with very mild AKC. We used the plasma from 32 AD patients with severe AKC, from 40 healthy controls, and from 23 AD patient without AKC or with very mild AKC without giant papillae nor shield ulcers. Quantitative microRNA PCR assays were used to measure their plasma level of miR‐628‐3p. We found that plasma miR‐628‐3p was upregulated in AD with severe AKC, but not in severe AD without severe AKC, nor in our healthy controls. Our new findings suggest that the plasma miR‐628‐3p level may represent a marker to predict the presence of severe AKC in AD patients.
