“The search for a better animal model to stimulate human disease has been a ‘holy grail’ of biomedical research for decades,” Yale University researchers write in a new book on the science and ethics of chimeras.
The monkeys in Douglas Munoz’s Kingston lab look like other monkeys.
They socialize and move around and eat and drink in the same way. They don’t fall over or stagger around. In fact, the only thing separating the macaques from their unaltered lab mates is the elevated level of a specific human protein implanted inside their brains — proteins that accumulate in the brains of humans with Alzheimer’s disease.
