UVB-Induced MVP Release in Human Skin

February 22, 2023 updated by: Wright State University

Ultraviolet B Radiation-Induced Microvesicle Particle Release in Human Skin

This study is designed to assess if ultraviolet B radiation (UVB) found in sunlight causes the release of microvesicle particles in human skin, and if antioxidant vitamins can block their production.
