概括

亚托皮炎 (AD) 显著损害了皮肤屏障功能,改变了皮肤的地形. 这项研究显示,阿尔茨海默病患者的皮肤间流失水分增加和水分减少,以及皮肤表面特征的变化.

科学领域:

皮肤病学皮肤病学
皮肤屏障研究研究
生物医学工程生物医学工程

背景情况:

亚托皮炎 (AD) 是一种日益严重的慢性炎症性皮肤疾病.
皮肤屏障功能障碍,其特点是皮肤间流失水分增加 (TEWL) 和角层水分减少 (SCH),是AD的一个关键特征.
关于阿尔茨海默病患者皮肤微观图形变化的数据有限.

研究的目的:

为了全面评估皮肤屏障功能障碍在患有亚托邦性皮肤炎的患者.
为了研究阿兹海默症患者皮肤的结构和地形变化.
为了比较皮肤屏障和地形参数之间的健康皮肤和疹病变在AD.

主要方法:

一项涉及32名被诊断患有亚托皮性皮肤炎的患者的横截面研究.
测量关键的皮肤屏障功能参数:TEWL,温度,红斑,pH,皮肤水分和弹性.
对地形参数的评估,包括,纹,光滑,表面积,对比度和在受损皮肤和健康皮肤上的变异.

主要成果:

与健康皮肤相比,柔性湿疹病变的红血和TEWL显著增加,SCH和弹性相比较低.
地形分析显示,AD病变的度,光滑度,纹,表面积,对比度和变异性增加.
在受损皮肤中观察到细胞数显著减少,这表明在亚托皮炎中皮肤质量受到损害.

结论:

皮肤屏障功能和皮肤拓在阿托皮性皮肤炎患者中显著受损.
在AD中,健康的皮肤和湿疹性病变之间存在明显的皮肤屏障参数和地形特征的差异.
这些发现强调了在亚托皮炎中皮肤损伤的多面性,影响了屏障完整性和表面结构.

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
