Pinpointing the Cells that keep the Body’s Master Circadian Clock Ticking

The image shows a series of suprachiasmatic nucleus slices expressing click beetle green in AVP neurons and click beetle red in non-AVP neurons. As time progresses (spiraling into the image), the AVP (green) and non-AVP (red) neurons luminesce together rhythmically, thanks to the intact genetic clocks of the AVP neurons and exchange of neuronal signals.

A new mouse model helps researchers study the roles of cell types in keeping time inside the body. UT Southwestern scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice...
