Brain cells communicate through neurotransmitters like glutamate or dopamine, the substances we got used to read about when learning about brain function. However, it seems this is not the only way neurons can communicate. A new study suggests that certain proteins can act as brain messengers in the brain.
Previously, only pathological proteins like tau or prions were known to transfer from one cell to the next, but whether this mechanism also took place in “normal” conditions was not clear.
