July 9 (HealthDay News) -- Sunburned skin is detected through
release of damaged RNA, which stimulates an inflammatory
response from the surrounding cells, according to research
published online July 8 in Nature Medicine. Jamie J. Bernard,
Ph.D., from the University of California San Diego, and
colleagues treated skin cells with acute ultraviolet B radiation
to investigate how skin detects damaging levels of ultraviolet
radiation that trigger the inflammatory response. The
researchers found that radiation caused release of RNA from the
irradiated cells. Sequencing revealed that irradiation of
keratinocytes induced alterations in some double-stranded
noncoding domains. These damaged self-RNAs induced production of
the inflammatory cytokines tumor necrosis facto
