Overview

It is thought that Atopic dermatitis is caused by either skin barrier dysfunction or immune dysregulation.

Pathophysiology

Physiology

The normal physiology of skin barrier function and immune regulation can be understood as follows:

• Skin Barrier: In the epidermis, stratum corneum consisting of stacks of anucleate corneocytes filled with keratin filaments serves as the first line of defense between the body and the environment. Interactions between terminal differentiated keratinocytes and structural proteins such as lipids, regulatory enzymes and filaggrin, determine the permeability of epidermis.

Pathogenesis

• The exact pathogenesis of [disease name] is not completely understood.

OR

• It is understood that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
• [Pathogen name] is usually transmitted via the [transmission route] route to the human host.
• Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
• [Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
• The progression to [disease name] usually involves the [molecular pathway].
• The pathophysiology of [disease/malignancy] depends on the histological subtype.

Genetics
