Inflammation-induced alterations in the skin barrier function: implications in atopic dermatitis
Chemical Immunology and Allergy
|March 22, 2012
Summary
Inflammation in atopic dermatitis (AD) can disrupt the skin barrier by affecting filaggrin, a key skin component. This finding suggests inflammation may directly worsen AD symptoms by impairing skin barrier function.
Area of Science:
- Dermatology
- Immunology
- Biochemistry
Background:
- Atopic dermatitis (AD) pathogenesis involves skin inflammation and barrier disruption.
- These factors were historically studied independently.
- Recent research suggests a link between inflammation and skin barrier integrity.
Purpose of the Study:
- To investigate the interplay between inflammatory processes and skin barrier function in AD.
- To explore how inflammatory cytokines influence key skin barrier proteins like filaggrin.
Main Methods:
- Review of existing literature on AD pathogenesis.
- Analysis of studies examining cytokine regulation of filaggrin and related proteins.
Main Results:
- Inflammatory cytokines can regulate filaggrin, a crucial skin barrier protein.
- Cytokines also impact proteins involved in filaggrin processing and maturation.
- Inflammation may directly induce functional skin barrier defects.
Conclusions:
- Skin inflammation can directly cause or exacerbate skin barrier dysfunction in AD.
- This bidirectional relationship highlights inflammation's role in worsening eczematous reactions.
- Understanding this link is vital for developing targeted AD therapies.

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:23Skin 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...

01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:26Asthma-II: Pathophysiology and Classification
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:
