For type 2 diabetes mice, we also measured for changes in the body weight, glucose level, A1c, insulin, and IR for db/db‐htau mice (Figure S2A–E), and A1c and insulin concentration for db/db‐tau knock‐out (db/db‐tauKO) mice (Figure S2F–G), showing a high level of glucose, A1c, and insulin levels in db/db, db/db‐htau, and db/db‐tauKO mice. Here, MAPT is linked to type 2 diabetes mellitus.
