Nanoparticle Developed To Boost Anti-Cancer Immunotherapy

(PhysOrg.com) -- One of the hallmarks of cancer is that tumors are able to suppress the immune system, preventing the body's own defense system from eliminating the disease, particularly as tumors spread through the body. Cancer researchers have identified the molecule responsible for this unwanted immune suppression, and have even designed an inhibitor of this molecule. Now, they have the means of delivering this molecule to tumors - a biocompatible polymer nanoparticle that will release potentially therapeutic levels of the inhibitor for as long as a month at a time.
