adjuvant

It’s the princess’ first official engagement since she concluded adjuvant chemotherapy for an undisclosed form of cancer.

Neither the palace nor the princess has said what stage of cancer she was diagnosed with, only that it was discovered after she had “major abdominal surgery” in January and that she was being treated with preventive chemotherapy, a secondary treatment that in the U.S. is known as adjuvant chemotherapy.

"During the pandemic, public health officers were really worried about QS-21 adjuvant availability because that only comes from one tree," said Jay Keasling, UC Berkeley professor of chemical and biomolecular engineering and senior faculty scientist at Berkeley Lab.

"From a world health perspective, there's a lot of need for an alternative source of this adjuvant."

"The production of the potent vaccine adjuvant QS-21 in yeast highlights the power of synthetic biology to address both major environmental, as well as human, health challenges," said former UC Berkeley postdoctoral fellow Yuzhong Liu, first author of the paper and now an assistant professor at Scripps Research in La Jolla, California.
