Virus Infection Supports Organ Acceptance

June 26, 2014 1:19 pm | News | Comments

Chronic hepatitis C virus infections are among the most common reasons for liver transplants. Because existing viruses also infect the new liver, the immune system is highly active there. Despite this, the new organ is not rejected. The long-term stimulation of the innate immune system by the virus actually increases the probability of tolerance.

ASCO Recap: Leaning in at the Plate, Swinging for the Fences

June 17, 2014 1:57 pm | by Neil Canavan | Articles | Comments

Everyone loves a grand slam: the crack of the bat, the arc of the ball as it sails over the fence, a tip of the batter’s cap, a triumphal trot around as the bases empty out, but really, it’s the lesser efforts that made it all possible—a double, a single, a walk—it’s the incremental gains that win the game. It’s called Small Ball. This year’s ASCO, absent the heavy hitters, was all about the small ball.
