概括
使用皮肤贴片的皮肤上皮肤免疫疗法显示出对儿童对食物过敏原不敏感的承诺. 这种方法利用皮肤.
科学领域:
- 免疫学 免疫学 免疫学
- 皮肤病学 皮肤病学
- 过敏研究 研究过敏
背景情况:
- 皮肤是人体最大的免疫器官,在食物过敏原敏感和耐受性方面发挥着至关重要的作用.
- 双重过敏原暴露假说表明,皮肤暴露在炎症皮肤上 (例如,亚托皮炎) 可以导致敏感化,而口服则促进耐受性.
- 然而,对过敏原敏感化的复杂机制,即使在患有亚托皮炎的儿童中也是如此,尚不完全理解,这表明其他因素也会影响结果.
研究的目的:
- 研究皮肤屏障状态在皮肤过敏原暴露的结果确定中的作用.
- 探索皮肤上免疫疗法 (EPIT) 诱导对食物过敏原脱敏的潜力.
- 评估EPIT在患有花生过敏的儿童的疗效和安全性,包括患有亚托皮炎的儿童.
主要方法:
- 在临床前的研究中,使用隐蔽贴片将过敏原涂在皮肤上,评估免疫反应和调节性T细胞诱导.
- 临床试验涉及1至11岁的花生过敏儿童,他们接受了用遮贴片进行皮肤上免疫疗法.
- 在有和没有亚托皮性皮肤炎的儿童之间比较了疗效和安全性.
主要成果:
- 临床前研究表明,将过敏原应用于完好无损,未炎症的皮肤可以减少T-辅助细胞2型反应,并诱导保护性调节性T细胞.
- 临床研究表明,在治疗皮免疫疗法的花生过敏儿童中,显著降低了敏感性.
- 在患有和没有亚托皮性皮肤炎的儿童之间,没有观察到有效性或安全性的重大差异.
结论:
- 皮肤屏障的状态显著影响皮肤过敏原暴露的免疫结果,健康的皮肤促进了耐受性.
- 皮肤上免疫疗法是诱导食物过敏原脱敏的可行策略,即使在患有亚托皮炎的儿童中也是如此.

Hypersensitivities
615
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Allergic Drug Reactions
838
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Clinical Applications of Epidermal Stem Cells
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 Diseases and Disorders

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...
