Sean Ainsworth hopes to strike biotech gold, again, joining Seattle-based Immusoft Corp. as CEO and chairman. Immusoft is a gene-therapy company that hopes to use a patient’s immune cells to treat diseases, including MPS-I, or mucopolysaccharidosis type I, a rare genetic disease that is expected to be Immusoft’s first clinical application. The company uses a cell-culture system invented by Nobel laureate David Baltimore that it calls Immune System Programming.
