Blood from these animals could hold key to Alzheimer’s cure, study finds

Tiny protein molecules derived from the blood of llamas and camels could be useful in treating brain disorders such as Alzheimer’s disease with fewer side effects, a new study says.

These nanobodies are a form of the immune system’s antibodies, and were first discovered in the 1990s in the camelid family, which includes camels, llamas, and alpacas.
