科学领域:
- 皮肤病学 皮肤病学
- 药理学 药理学是指药理学的学科.
- 毒理学 毒理学 毒理学
背景情况:
- 一个功能性的人体皮肤屏障对于防护环境剂至关重要,并调节局部产品的吸收.
- 皮肤屏障功能的个体差异,受内在和外在因素的影响,对于皮肤产品安全性评估至关重要.
- 在特定的种族群体中观察到的某些皮肤病理的倾向表明皮肤的潜在生理差异,包括屏障功能.
研究的目的:
- 审查皮肤透现有的数据与种族和皮肤颜色的关系.
- 要突出评估皮肤吸收的方法的进步.
- 确定在皮肤吸收研究中更好地代表人类人口多样性的研究机会.
主要方法:
- 对皮肤透和皮肤吸收研究的现有文献进行分析.
- 评估体内和体外方法来评估化合物通过人体皮肤的透.
- 对重建的人类有色素皮肤模型的实用性进行评估.
主要成果:
- 目前的数据将人类皮肤屏障功能与种族相关,由于不同的实验方法,这些数据往往是冲突的.
- 重建人类皮肤模型的进步允许将来自不同种族背景和色素水平的黑色素细胞纳入.
- 试验室方法为标准化皮肤吸收研究提供了潜力.
