Scientists rewrite the genesis of mosquito-borne viruses

Better designed vaccines for insect-spread viruses like dengue and Zika are likely after researchers discovered models of immature flavivirus particles were originally misinterpreted.

Stress slows the immune response in sick mice

The neurotransmitter noradrenaline, which plays a key role in the fight-or-flight stress response, impairs immune responses by inhibiting the movements of various white blood cells in different tissues, researchers report April 28th in the journal Immunity. The fast and transient effect occurred in mice with infections and cancer, but for now, it’s unclear whether the […]
