Abstract
Small molecules that specifically inhibit PI3K
block disease in mouse models of arthritis and lupus (pages 936–943).
Drugs that target enzymes with multiple isoforms run the risk of affecting too many cellular processes, because many isoforms perform redundant functions. Gene knockout mice of these molecules, however, often reveal selective roles, raising the possibility of precise modulation through use of highly specific, isoform-selective drugs.
