young mice Semiquantitative analysis of the burden of clustered immunoreactive puncta in the hippocampal formation of all 40 mice (i.e., 22 young and 18 aged mice) revealed a highly significant linear trend toward greater load in aged mice ( p < 0.0001 for each of LC3, p62, ubiquitin, MAP2, and synapsin IIa stainings; χ 2 test for linear trend [Fig. 3a–e ]).
