Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Researchers investigate cell-free DNA as early sepsis marker in foals
It's hard to be a horse. It's especially hard to be a newborn foal, dropped into a world of microbes and bacteria with your sole initial defense against devastating infections being the antibodies you get from your mother's milk, or colostrum. Resear.....»»
