Sun Burn and Pain

Sunburn Study May Lead To Drugs To Treat Pain In Other Common Conditions.

Reuters (7/7, Kelland) reports that, according to a study published in Science Translational Medicine, researchers have found a molecule in the body, CXCL5, which controls sensitivity to pain from UVB irradiation. The molecule may help them develop new treatments to treat pain in other conditions, according to the researchers.

        The USA Today (7/6, Lebowitz) "Science Fair" blog reported CXCL5 "recruits immune cells to human flesh exposed to ultraviolet-B (UVB) rays, swelling the skin and triggering pain and tenderness." The researchers "exposed numerous samples of human and rat skin to different types of solar waves." After looking at the skin samples under a microscope, the researchers "observed a variety of proteins in the damaged tissue, including large quantities of CXCL5. Such abundance of the protein is what causes the skin tissue to redden and blister when in the presence the sun's harmful rays."

        Also covering the story were, on its website, ABC News (7/6, Moisse), the Wall Street Journal (7/6, Hobson, Subscription Publication) "Health Blog," the UK's Telegraph (7/7, Collins), BBC News (7/6) and WebMD (7/6, Warner).
