Scientists have discovered that blocking PD-1 (programmed death-1), an immune molecule that inhibits the immune response to viral infections, can have a significant effect on HIV-like illness in nonhuman primates.

Good news! Researchers have discovered a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer.

In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer.

After eight years of work, researchers have unearthed what has been a well-kept secret of our immune system's success.

Killer T cells begin to divide en route to virus-infected tissue, allowing them to hit the ground running when they arrive.
