How Natural Killer cells regulate protective HIV antibodies
In the quest to develop a vaccine that triggers the immune system to prevent HIV infection, researchers have focused on identifying and eliciting a particular type of antibody that is capable of neutr..
Skin is a battlefield for mutations
Normal skin contains a patchwork of mutated cells, yet very few go on to eventually form cancer and scientists have now uncovered the reason why. Researchers genetically engineered mice to show that m..
