Parasites' impact goes beyond host to affect ecosystem

The good news, if you’re grazing normally on algae in the rocky intertidal zone of the North Atlantic, is that you may not be infected by a parasite.

Protease inhibitors reach beyond HIV

The immunodeficiency that arises in HIV may be due to excessive programmed cell death of immune CD4 T cells. HIV protease inhibitors (PI) can block programmed cell death in virus-infected T cells in vitro, but have also been shown to induce programmed cell death at higher concentrations. The mechan...
