概括
皮肤细胞Bcl6 (B细胞淋巴瘤6) 的下调会加剧阿托皮性皮肤炎 (AD) 的炎症. Bcl6的丧失会损害角质细胞的分化,并使小鼠的AD类皮肤状况恶化.
科学领域:
- 皮肤病学 皮肤病学
- 免疫学 免疫学 免疫学
- 分子生物学分子生物学
背景情况:
- 亚托匹性皮肤炎 (AD) 是一种慢性炎症性皮肤疾病,其特征是主导的Th2免疫反应.
- 在AD病变中的角质细胞表现出分化缺陷并分泌细胞因子,放大Th2反应.
- 以前的研究将全身Bcl6损失与小鼠皮肤中Th2细胞因子的增加联系起来.
研究的目的:
- 为了研究B细胞淋巴瘤6 (Bcl6) 在皮细胞中关于亚托皮性皮炎的特定作用.
- 为了确定在角质细胞中Bcl6缺乏是否会影响AD类皮肤炎症.
主要方法:
- 利用角质细胞细胞培养来评估BCL6对分化标志物和蛋白质定位的影响.
- 产生的小鼠具有质细胞特异性Bcl6损失.
- 使用MC903诱导了类似AD的皮肤炎症,并评估了Bcl6缺乏的影响.
- 在炎症皮肤的表皮中分析了Bcl6表达水平.
主要成果:
- 发现Bcl6可以积极调节角质细胞分化标记物和粘附结位蛋白位址.
- 单独的类细胞特异性Bcl6损失并没有引起AD类炎症,但加剧了MC903诱导的炎症.

2.7K
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...

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
