Are you specifically interested in iv adminstration or peripheral administration of tau fibrils? I know of only one paper that describes intraperitoneal administration of tau aggregates with seeding in transgenic mouse brain, see:http://link.springer.com/article/10.1007%2Fs00401-013-1231-5

thanx Dick.

Indeed IV is preferred route for try-out, peripheral is 2nd option. No papers to find on IV admin of tau fibrils.
