Too much of a good thing: Detrimental effects of interferon.

Abstract excerpt

Healthy tissues of the body express relatively low basal levels of interferons. However, following detection of microbial invasion by sentinel receptors, a cascade of events initiates leading to the transcriptional induction of interferon genes.
