Read moreProtein 'passport' helps nanoparticles get past immune system
The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt, or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices, like pacemakers or artificial joints, are just as foreign and subject to the same response. Now, however, a team of researchers has identified a 'passport' for such therapeutic devices, enabling them to get past the body's security system.

Researchers at the University of Missouri have demonstrated the ability to create a multi-layered harness nanoparticle that can safely encapsulate powerful alpha-emitting radioisotopes and target tumors. The resulting nanoparticles not only offer the possibility of delivering tumor-killing alpha emitters to tumors, but also sparing healthy tissue from radiation damage.

In the quest to develop anti-cancer vaccines that would stimulate the body to destroy tumors and keep them from recurring, researchers continually run into the same problem - the immune-stimulating proteins, known as antigens, are not interacting effectively with the key immune system cells that trigger long-lasting immune responses. Now, using a novel administration system and polymer nanoparticles, a team of investigators led by Adrien Kissenpfennig of Queen's University Belfast has shown that they can deliver anticancer antigens to dendritic cells and trigger an effective immune system response against melanoma tumors.

Read moreNew nanopore sensor simplifies analysis of methylated DNA
DNA methylation, the addition of a methyl group to specific locations on a DNA strand, plays a critical role in determining which genes are active in a cell at any given time. It plays an important role in embryonic development, cell growth and reproduction, and many diseases, including cancer. Now, researchers collaborating at the Mayo Clinic and the University of Illinois in Urbana-Champaign have developed a novel single molecule test for detecting DNA methylation that should greatly simplify and advance the study of this important genomic process.
