Stanford snake venom study shows that certain cells may eliminate poison

...st cell response runs contrary to the conventional wisdom - that the immune system only added to the woes of snakebite victims. This assumption arose because of the way mast cells respond to certain other stimuli. Mast cells synthesize a wide range of biological mediators - compounds that can promote infl...

UGA study explains peaks and troughs of dengue epidemics

The conventional wisdom is that an amplification of the severity of disease caused by repeat infections with different strains, a phenomenon known as antibody-dependent enhancement, drives the boom and bust cycles of dengue epidemics.
