From: Active full-length DNA Aβ42 immunization in 3xTg-AD mice reduces not only amyloid deposition but also tau pathology

  1. Bold letters indicate differences higher than 20% in DNA Aβ42 trimer immunized mice compared to Aβ42 peptide immunized mice; letters in bold cursive font indicate high significance for differences in reduction of tau in DNA Aβ42 trimer and Aβ42 peptide immunized mice compared to the control mice, and in the comparison of the two immunization groups (Mann Whitney u test).
  2. * indicates p values ≤0.05, ** indicates p values ≤0.005, *** indicates p values ≤0.001, and **** indicates p values < 0.0001. All data are based on the analyses and comparison of seven DNA Aβ42 trimer immunized mice, nine Aβ42 peptide immunized mice, and 14 age and gender matched 3xTg-AD control mice
