Emory scientists track down immune sentinel cells with gene gun

All the cells in the skin received the trigger signal, but only the dendritic cells migrated to the draining lymph nodes.

Once people get the idea that studying environmental risks is a powerful research tool, there ought to be more success in finding undocumented relationships between genes and all sorts of diseases." The idea, according to Mo......their bodies, their internal hydrostatic pressures shot up, she said. Still more measurements, taken as control experiments, showed that seven days after molting, internal pressures did not increase when the animals pulled in their claws.

For example, smokers with at least one KL-VS copy had more than seven times the risk of non-smokers without the gene variant.
