Exposure to ultraviolet light (UV) may cause a type of DNA mutation not previously known to be associated with skin cancer, according to researchers who sequenced the genome of UV-irradiated yeast samples.
Survey: Most know UV protection is important, but still fail to protect themselves
May is Skin Cancer Awareness Month in the U.S., and the American Academy of Dermatology (AAD) has released the results of a survey that found that although most Americans know sun protection is important, they still fail to adequately protect themselves from ultraviolet light (UV) exposure. A second press release from the AAD also said that there is no evidence to support claims that UV exposure may be effective in treating Covid-19, warning the public that the risks of UV radiation outweigh any perceived positive effects.
New insights into T cell reaction to UVR inflammation
Exposure to ultraviolet radiation causes a pair of specific T cell types in the skin to intervene to suppress inflammation and help the skin repair itself, according to a new study. The study, published online in Clinical & Translational Immunology (Apr. 2, 2020), found that T cells D4+GATA3+ and CD8+GATA3+ are sent to the inflamed area and can affect the area for two weeks.
