Scientists identify molecular trigger for Alzheimer's disease

Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease – when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.

Scientists design protein that prods cancer-fighting T-cells

Scientists at UW Medicine's Institute for Protein Design (IPD) in Seattle have created a new protein that mimics the action of a key immune regulatory protein, interleukin 2 (IL-2).  IL-2 is a potent anticancer drug and ...

Neurons with good housekeeping are protected from Alzheimer's

Some neurons in the brain protect themselves from Alzheimer's with a cellular cleaning system that sweeps away toxic proteins associated with the disease, according to a new study from Columbia University and the University ...

Cellular pumps protect the gut from toxins

The master regulators of gut stem cells, called intestinal myofibroblasts, have pumps that protect them, and thus the gut, from the toxic effects of a wide range of compounds, including the anticancer drug tamoxifen, according ...
