Genome sequencing has revealed a potential function for circular RNAs in the immune response.

Circular RNAs are a type of RNA — molecules that regulate genetic activity — that has formed in a circle rather than a straight line. Their function in cells is not entirely clear as the closed loop reduces the likelihood of reactions with other molecules.

A team including researchers from the University of Chinese Academy of Sciences used all-human genome sequencing to investigate how circular RNAs form under different conditions. They found that, during viral infections, a drop in the number of two antibodies, the proteins NF90 and NF110, in the nucleus led to a decrease in the number of circular RNA. The team suggest that the two proteins regulate the growth of circular RNA, with which they coordinate a response to viral infections.

Further investigations into the formation and function of circular RNAs may reveal their wider role in immunity.
