Eotaxins are the chemokines which are highly selective chemotactic agents for eosinophils. The aim of our study was the evaluation of the gene expression level for eotaxin 1/CCL11, eotaxin 2/CCL24, and eotaxin 3/CCL26, both in skin changes and in uninvolved skin of atopic dermatitis (AD) patients. The study comprised 19 patients with AD and 10 healthy controls. The gene expression level for eotaxins in the skin biopsies was evaluated by the real-time quantitative PCR. The change of the gene expression level, calculated as log10 skin lesions/non-lesional skin, was 0.635 for CCL11, 0.172 for CCL24 and 0.291 for CCL26. The change of the gene expression level, calculated as log10 non-lesional skin of AD patients/healthy control, was 0.394 for CCL11, -0.216 for CCL24, and 0.229 for CCL26, while skin lesions of AD patients/healthy control, was: 0.788, -0.046, and 0.483, respectively.
The mean gene expression level for CCL11, CCL24, CCL26 was higher in skin changes of AD patients than in uninvolved skin. The higher level of CCL26 in skin changes, indicates its role in their aetiology in AD. The gene expression level for CCL24 in AD patients was lower, both in involved and uninvolved skin vs. the healthy control.
嗜酸性粒细胞趋化因子是高度选择性的嗜酸性粒细胞趋化因子。我们研究的目的是评估特应性皮炎(AD)患者皮损和未受累皮肤中嗜酸性粒细胞趋化因子 1/CCL11、嗜酸性粒细胞趋化因子 2/CCL24 和嗜酸性粒细胞趋化因子 3/CCL26 的基因表达水平。该研究包括 19 例 AD 患者和 10 例健康对照者。通过实时定量 PCR 评估皮肤活检中嗜酸性粒细胞趋化因子的基因表达水平。基因表达水平的变化,以皮损/非皮损皮肤的对数 10 表示,CCL11 为 0.635,CCL24 为 0.172,CCL26 为 0.291。基因表达水平的变化,以 AD 患者非皮损皮肤/健康对照的对数 10 表示,CCL11 为 0.394,CCL24 为-0.216,CCL26 为 0.229,而 AD 患者皮损/健康对照者分别为:0.788、-0.046 和 0.483。
与未受累皮肤相比,AD 患者皮损中 CCL11、CCL24、CCL26 的平均基因表达水平更高。CCL26 在皮损中的水平较高,表明其在 AD 发病机制中的作用。AD 患者皮损和未受累皮肤中 CCL24 的基因表达水平均低于健康对照者。
