GFAP, tubulin and plectin were significantly enriched in aggregates from AD relative to AMC, isolated by immuno-pulldown (IP) with antibodies to Aβ1–42 (amyloid-β) or tau, whereas only GFAP and plectin were also significantly enriched (although to a lesser extent) in total insoluble aggregates (Ayyadevara et al., 2016b; Figures 7B–E). This evidence concerns the gene MAPT and Alzheimer disease.
