The present invention relates to anti-Tau antibodies, such as antibodies that bind to a phosphorylated epitope on human Tau protein with high specificity and/or affinity, and methods of using the same. 1. An isolated antibody that binds to a phosphorylated epitope of Tau protein , wherein the antibody comprises at least one sequence selected from the group consisting of HVR-L1 , HVR-L2 and HVR-L3 , wherein:{'sub': 1', '2', '3', '4', '5', '6', '7', '8', '1', '2', '3', '4', '5', '6', '7', '8, '(a) HVR-L1 comprises the amino acid sequence XSSQXLXXXXGXTYXH (SEQ ID NO:89), wherein X=R or T; X=S, R or V; X=V, I or R; X=H or R; X=S, R, G or K; X=H, N, R, K or G; X=K or R; and X=L or V;'}{'sub': 9', '10', '11', '9', '10', '11, '(b) HVR-L2 comprises the amino acid sequence KVXXRFX(SEQ ID NO:90), wherein X=S, K or R; X=N, K or H; and X=S, F, G, K, R, Y or L; and'}{'sub': 12', '13', '14', '12', '13', '14, '(c) HVR-L3 comprises the amino acid sequence SQTXXFPXT (SEQ ID NO:91), wherein X=A or R; X=H, R, Q or Y; X=Y or R;'}and wherein the antibody does not comprise an HVR-L1, HVR-L2 and HVR-L3 wherein the HVR-L1 amino acid sequence is RSSQSLVHSHGKTYLH (SEQ ID NO:15) or RSSQRLVHSHGKTYLH (SEQ ID NO:92); the HVR-L2 amino acid sequence is KVSNRFS (SEQ ID NO:16); and the HVR-L3 amino acid sequence is SQTAHFPYT (SEQ ID NO:30).2. The antibody of claim 1 , wherein the phosphorylated epitope includes a phosphorylated amino acid residue selected from the group consisting of serine at position 409 of human tau (SEQ ID NO:59); serine at position 404 of human tau (SEQ ID NO:59); and serine at position 404 and 409 of human tau (SEQ ID NO:59).3. The antibody of any one of or claim 1 , wherein the antibody comprises at least one sequence selected from the group consisting of HVR-H1 claim 1 , HVR-H2 and HVR-H3 claim 1 , wherein HVR-H1 comprises the amino acid sequence GYTFTDYYMN (SEQ ID NO:33); HVR-H2 comprises the amino acid sequence DINPNRGGTTYNQKFKG (SEQ ID NO:34); and HVR-H3 comprises the ...
