New #ScienceImmunology research involving mice and human tissues demonstrates how different immune cell types modify expression of stimulator of interferon genes (STING) to support their normal development and function. scim.ag/4idx7wn
Dynamic STING repression orchestrates immune cell development and function
Repression of STING expression in neutrophils and T lymphocytes is required for immune homeostasis and tumor response.

The best part of science for me is when someone in the lab or a former lab member has awesome new data and rushes to share it. everything else pales in comparison.
