Researchers Develop Virtual Molecular Library of Thousands of 'Command Sentences' for Cells

Cellular 'Command Sentences'.

News-Medical Life Sciences, Emily Henderson,  December 8, 2022

Researchers at the University of California, San Francisco (UCSF) and IBM Research have compiled a virtual molecular database of thousands of cellular "command sentences." The researchers based the sentences on combinations of molecular "words" that directed engineered CAR-T immune cells to hunt down and destroy cancer cells. USCF's Wendell Lim and Kyle Daniels concentrated on the part of a receptor within the cell containing amino acid strings, each of which functions as a command "word." Stringing the words into a "sentence" influences the commands the cell will follow. Daniels and the IBM researchers applied novel machine learning to the data to produce new receptor sentences to boost the CART-T cells' effectiveness.
