Researchers from Mount Sinai, New York City, have discovered a key mechanism by which radiation treatment (radiotherapy) fails to completely destroy tumors. They offer a novel solution to promote successful radiotherapy for the millions of cancer patients who are treated with it.
Researchers from the Gladstone Institutes have revealed that HIV does not cause AIDS by the virus' direct effect on the host's immune cells, but rather through the cells' lethal influence on one another.
Just as the brain forms memories of familiar faces, the immune system remembers pathogens it has encountered in the past. T cells with these memories circulate in the blood stream looking for sites of new infection.
A research team, led by Weill Cornell Medical College scientists, has discovered a way to limit replication of the most common form of HIV at a key moment when the infection is just starting to develop.
