New study finds how cells with damaged DNA alert the immune system

...ating immune responses to infectious diseases, but given what we have shown here, it is certainly plausible that it contributes to the expression of the NKG2D ligand," said Raulet. "It may also be that the Rae1 ligand helps trigger T cell responses that contribute to long term specific immunity. It's certa...

As a comparison, they looked at a second contact zone on the border between north and south, where frogs were not isolated from either lineage. "Reinforcement does not appear to occur at th...

This signal essentially puts the plant on alert, but staying on alert too long can be harmful: If not reduced quickly, the toxic superoxide will kill plant cells.Since the superoxide reductase gene is no...
