Scientists Develop Method to Track Immune System Enzyme in Live Animals

...ks to these new mouse models, we can track in live animals whenever the AID enzyme is active as well as the result of that activity, says Casellas. Scientists can also cross these new mouse strains with mice predisposed to B-cell tumors or autoimmunity to see differences in enzyme expression in health and di...

Lipoic Acid may Help to Live Long, Free of Degenerative Disease

...lutathione levels naturally decline and make older animals more susceptible to both free radicals and other environmental toxins, but lipoic acid can restore glutathione function to near normal. "We never really expected such a surprising range of benefits from one compound. This is really unprecedented, ...

UW Establishes Stem Cell and Regenerative Medicine Center

We can then use these insights to predict where and when zoonotic disease outbreaks will occur so we can target surveillance and intervention," Real said. "Our study demonstrates the combined evolutionary and po...
