Low‐dose UVB radiation perturbs the functional expression of B7.1 and B7.2 co‐stimulatory molecules on human Langerhans cells
1 Oct 1995
Abstract excerpt
In previous studies, we have shown that ultraviolet (UV) B radiation perturbs the APC function of Langerhans cells (LC) by interfering with as-yet unidentified co-stimulatory signals. Recently, B7.1 and B7.2 on APC were shown to deliver important co-stimulatory signals through interaction with their counter receptors CD28 and CTLA-4 on T cells. To determine whether UVB affects the functional expression of B7.1 or...
