Chemists at the University of California, San Diego have produced the first high resolution structure of a molecule that when attached to the genetic material of the hepatitis C virus prevents it from reproducing.

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus.

Brain-tumor cells that are infected with a cancer-killing virus release a protein "alarm bell" that warns other tumor cells of the impending infection and enables them to mount a defense against the virus, according to a study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James).

A team of researchers led by scientists at The Rockefeller University has identified a novel mechanism by which influenza interferes with antiviral host response. The finding, reported in this week's issue of the journal Nature, shows that the immunosuppressive NS1 protein of the influenza A virus hijacks key regulators of antiviral gene function by mimicking a core component of gene regulating machinery.

A study by Columbia researchers suggests that cells in the patient's intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant. Until now, stem cell transplants have been seen by many researchers as the ideal way to replace cells lost in type I diabetes and to free patients from insulin injections.

As scientists continue making breakthroughs in personalized cancer treatment, delivering those therapies in the most cost effective manner has become increasingly important. Now researchers at the University of Colorado School of Medicine have identified new ways of doing just that, allowing more patients to benefit from this revolution in cancer care.

In what may prove to be a major step forward for the treatment of HIV-1 infection, scientists have discovered an effective way to eliminate a notoriously persistent form of the virus that does not respond to current therapies.
