大麻素受体2 (CB2) 在囊中高度表达,与desmoglein 3 (DSG3) 相对应. 一种CB2抑制剂AM630降低了CB2和DSG3水平,这表明尾虫的潜在治疗点.
科学领域:
- 免疫学 免疫学 免疫学
- 皮肤病学 皮肤病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 囊是一种自身免疫性疾病,其特征是形成水泡,通常涉及对desmogleins的自身抗体.
- 大麻素受体 (CBs),特别是CB2,已涉及到炎症过程.
研究的目的:
- 为了研究CB2抑制剂对与虫血清共培养的HaCaT细胞中desmoglein 3 (DSG3) 表达的作用.
- 探索胞患者的CB2表达及其与DSG3.3的相关性.
主要方法:
- 免疫组织化学和ELISA被用来评估虫患者和正常个体的CB2表达.
- 哈卡特细胞与虫血清共同培养,并用CB2抑制剂AM630.0治疗.
- 实时PCR和Western blot分析了CB2,DSG3和β-catenin的表达.
