Immune cells take cue from animal kingdom: Together, everyone achieves more Much like birds fly in flocks to conserve energy and ants create complex nests to protect their queens, immune cells engage in coordinated behavior to wipe out viruses like the flu. Scientists discovered that cells called neutrophils arrive at the site of injury within an hour of infection and leave a chemical 'trail' behind them. Killer immune cells called T cells use this trail to find the site of injury and destroy the invader
Immunity study signals new ways to treat liver failure Patients with liver failure could benefit from a treatment that helps the immune system to combat infections linked to the condition, research suggests. A study in mice has revealed that treatment with an immune-boosting molecule called CSF-1 helps to trigger the body's natural defense mechanisms in the liver.
Novel role of mitochondria identified in immune function A new role for an enzyme involved in cell death has been discovered by scientists. Their study shows how the enzyme, called RIPK3, relays signals between the cell’s mitochondria “powerhouses” and the immune system
Old vaccine trains immune system Not only the acquired immune system but also the innate immune system has a memory. And the BCG vaccine against tuberculosis can stimulate this memory, researchers report. After a BCG vaccination, the innate immune system responds better to a wide range of other infections
