Another targeted […]

Instead of strictly offensive measures (e.g. antivirals, antibiotics, and siRNA treatments), scientists are developing ways to improve our own natural defense against pathogens, our immune system. This can be done both by enhancing immune function and preventing immune overreactions. Enhancing the Immune System A study released last month found a way to protect mice from […]
