Outline of Final Research Achievements

Myofibroblasts are known to play an important role in inflammatory bowel diseases. Schizophyllan (SPG) can be used as a transporter of DNA sequence into cytoplasm via Dectin-1 which is expressed on the surface of myofibroblasts. We have investigated the application of this drug delivery system focusing on Foxl1. Inhibition of Foxl1 using antisense-Foxl1/SPG complex ameliorates body weight loss and significant increase in length of the colon and crypts in dextran sodium sulfate (DSS) colitis model.
