Summary
Atopic dermatitis (AD) involves skin barrier dysfunction, allowing allergens to cause inflammation and the atopic march. Understanding these barrier defects is key to managing AD and preventing its progression.
Area of Science:
- Dermatology
- Immunology
- Cell Biology
Background:
- Atopic dermatitis (AD) is a prevalent inflammatory skin condition.
- Abnormal skin barrier function is increasingly recognized as a key factor in AD pathogenesis.
- Impaired barriers permit allergen penetration, leading to chronic inflammation and the atopic march.
Purpose of the Study:
- To review recent advancements in understanding skin barrier dysfunction in AD.
- To explore the clinical implications of these skin barrier abnormalities.
- To highlight the importance of barrier maintenance in AD management.
Main Methods:
- Literature review of recent studies on atopic dermatitis and skin barrier function.
- Analysis of molecular and cellular components of the epidermal barrier.
- Correlation of barrier defects with clinical manifestations and disease progression.
Main Results:
- Defects in cornified cell envelope proteins, lipid metabolism, and cell junctions are common in AD.
- Impaired desquamation contributes to barrier abnormalities.
- Skin barrier dysfunction directly impacts inflammation and allergen sensitization.
Conclusions:
- Skin barrier integrity is crucial for preventing AD development and progression.
- Targeting skin barrier repair offers a promising therapeutic strategy for AD.
- Further research into barrier mechanisms is essential for improved AD patient outcomes.

3.2K
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 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...

01:21Accessory Structures of the Skin: Sebaceous Glands
3.7K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

01:12Renewal of Skin Epidermal Stem Cells
2.9K
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...

4.0K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:20Asthma: Pathogenesis and Management
1.1K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
