Researchers Probe Why Colds Are More Likely in Winter

“We used mouse airway cells as a model to study this question [and found that] at the cooler temperature found in the nose, the host immune system was unable to induce defense signals to block virus replication,” Iwasaki explained.

The researchers discuss their findings in the current issue of the Proceedings of the National Academy of Sciences.

To explore the potential relationship between internal body temperatures and the ability to fend off a virus, the research team incubated mouse cells in two different temperature settings. One group of cells was incubated at 37 C (99 F) to mimic the core temperature found in the lungs, and the other at 33 C (91 F) to mimic the temperature of the nose.
