Keratinocyte Proline-Rich Protein Deficiency in Atopic Dermatitis Leads to Barrier Disruption

Skin barrier in atopic dermatitis.

The skin represents the largest organ of the body and provides a vital interface between the body and the environment. Hereditary and acquired alterations of structural proteins and lipids of the stratum corneum and epidermal tight junctions leading to a diminished skin barrier function are major causative factors for a number of skin diseases, in particular atopic dermatitis (AD). This review ...

Skin barrier in atopic dermatitis.

Research about the skin barrier and its properties has increased significantly since the 60s, with studies that indicated its resistance when isolated, as well as its particularities in relation to skin permeability. At the same time, description of Odland bodies helped to understand how stratum corneum stability is maintained. The âbrick and mortarâ model is the most accepted so far. In this a...

Epidermal Barrier in Atopic Dermatitis

Atopic dermatitis (AD) is a complex disease that affects up to 20% of children and impacts the quality of patients and families in a significant manner. New insights into the pathophysiology of AD point to an important role of structural abnormalities in the epidermis combined with immune dysregulation. Filaggrin (FLG) is synthesized as a large precursor, profilaggrin, and is expressed in the u...

Skin barrier in atopic dermatitis: beyond filaggrin*

Atopic dermatitis is a chronic inflammatory skin disease with a complex pathogenesis, where changes in skin barrier and imbalance of the immune system are relevant factors. The skin forms a mechanic and immune barrier, regulating water loss from the internal to the external environment, and protecting the individual from external aggressions, such as microorganisms, ultraviolet radiation and ph...
