Role of thyroid hormones in slumber under investigation at Rutgers

Were really just beginning to learn the true extent of how these hormones impact our overall health, Martin says.

...e novelty of our study is the discovery that Bcl-3 acting on gene expression has a profound effect on inflammation, says Ruaidhri Carmody, PhD, Senior Research Investigator in the Department of Pathology and Laboratory Medicine and first author of the Science paper. By mimicking Bcl-3 activity, we may be ab...Identified mechanism in the malaria parasite to help it adapt to infected individuals

"But the example in this study happened in a blink of the eye, in terms of evolutionary time, and is a remarkable thing to get to observe."
