Skin microdialysis: methods, applications and future opportunities-an EAACI position paper

Area of Science:

• Dermatology
• Immunology
• Pharmacology

Background:

• Skin microdialysis (SMD) is a sampling technique for analyzing molecules in human skin's extracellular space.
• Despite its availability since the 1990s, SMD's potential in studying skin inflammation and allergies remains underutilized.
• An EAACI Task Force was established to promote knowledge and application of SMD.

Purpose of the Study:

• To provide an overview of current Skin Microdialysis applications in investigating skin diseases and reactions.
• To encourage wider adoption of SMD by detailing its methodology and uses.
• To present standardized operating procedures for in vivo and ex vivo SMD.

Main Methods:

• Review of current literature and applications of Skin Microdialysis.
• Focus on SMD's role in studying chronic inflammatory skin diseases (atopic dermatitis, urticaria, psoriasis).
• Exploration of SMD in type 1 hypersensitivity, drug hypersensitivity, UVB-induced inflammation, and drug penetration studies.

Main Results:

• SMD is a versatile tool for investigating pathophysiological mechanisms in various skin conditions.
• The paper details SMD's utility in understanding allergic and inflammatory skin reactions.
• Standardized procedures are provided to facilitate the technique's accessibility.

Conclusions:

• Skin Microdialysis is crucial for advancing the understanding of skin pathophysiology.
• This position paper aims to boost the utilization of SMD in clinical and preclinical research.
• Standardized protocols will enhance the reproducibility and accessibility of SMD studies.
