Alzheimers disease has been found to be able to protect the body from pathogens. Amyloid- beta, a substance that gums up the brains of the affected, contains a protein capable of imprisoning pathogens that threaten the body. Before this experiment, A-beta was tested in dishes and was found able to defeat the pathogens. The mice in this new experiment were engineered to have the human form of Amyloid-beta and the ones with more of it were able to defend themselves from the disease better than the others.
