Intense light activates proteins shown to protect against lung damage in mice, a discovery that could have major therapeutic implications for treating acute lung injury in humans, according to a new study. "Acute lung injury has a mortality rate of 40%," said lead author Tobias Eckle, M.D. "No specific therapy exists, and novel treatment options are needed." Eckle's team, which previously demonstrated that light can protect against cardiovascular disease, housed mice under intense rather than ambient light for seven days. This prompted a strong increase in the trough and peak levels of the pulmonary circadian rhythm protein - Period 2...
