MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Staphylococcus aureus is a common bacterial skin pathogen and its abundance is greatly increased on affected skin of eczema patients, especially during disease flares. However, how S. aureus induces skin inflammation and exacerbates the skin inflammation is incompletely understood.
In this study, we found that S. aureus exposure of mouse skin induced skin inflammation through an inflammatory mediator known as IL-36.
MedicalResearch.com: What should clinicians and patients take away from your report?
Response: A role for S. aureus in triggering IL-36 is an unexpected mechanism by which the host responds to pathogenic and virulent bacteria on the skin surface to promote cutaneous inflammation.
Our findings suggest that inhibition of IL-36 could serve a novel therapeutic approach to combat skin inflammation in eczema and other inflammatory skin diseases.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: Our future research involves the investigation of the mechanisms by which IL-36 is induced and how it causes skin inflammation.
