MAPT and Alzheimer disease: Quantification indicated there were substantial numbers of tau-positive puncta in the ipsilateral fimbria/fornix of injured TauP30L mice; approximately half as many as in injured 3xTg-AD mice (TauP301L: 63,180±9,636 tau-positive puncta per cubic mm of fimbria, n = 6, vs. 3xTg-AD mice: 138,887±35,543, n = 8, p = 0.1).
