New clues suggest how destructive immune cells wreak havoc in the brain

CD8 T cells wander into any tissue that is unhappy. I doubt that Tau overexpressing mice tell us much about the processes that cause damage in Alzheimer's. So I am not sure this tells us much. I don't know why it talks about neck lymph nodes because T cells there would have to go back in to the circulation and by chance end up in the brain with some blood going up the carotid.

This has all the hallmarks of immunobabble to me.
