Could the biological clock be a key ally in the fight against inflammatory disease? What if the symptoms and seriousness of certain inflammatory diseases were linked to time of day? Researchers have been working on this hypothesis, after noting that the seriousness and mortality associated with fulminant hepatitis were dependent on the time at which the disease was induced. Their study, conducted on human cells and mice, shows that the anti-inflammatory action of a biological clock protein could prevent the onset of fulminant hepatitis, by alleviating symptoms and increasing survival rates.
