About this study

Psoriasis is a skin condition characterised by patches of skin that are typically red, itchy and scaly.

This study aims to understand the underlying mechanisms that trigger psoriasis and involves a one off-visit to clinics.

The outcome of this project and knowledge gained will potentially support the development of new treatments for psoriasis and psoriatic arthritis.
