A key hallmark of Alzheimer Disease (AD) pathology is the accumulation of tau protein in the form of neurofibrillary tangles across large-scale networks of the human brain cortex. Currently, it is still unclear how tau accumulates within specific cortical systems, and whether in situ genetic traits play a role in this circuit-based propagation progression. In this study, using two independent cohorts of cognitively healthy older participants, we reveal the backbone of tau spreading and its network intersections with high-resolution transcriptomic genetic data. We observed that specific connectomic-genetic gradients exist along the tau spreading network. Particularly, we identified 577 genes that significantly accompany the spatial spreading of tau; a set of genes in which APOE and glutamatergic synaptic genes (e.g. SLC1A2) play a central role. Thus, our study characterizes neurogenetic topological vulnerabilities in distinctive brain circuits of tau spreading and suggests that drug development strategies targeting the gradient expression of this set of genes should be explored to help stop or prevent the accumulation of tau. Tau accumulation is related to a gradient gene-expression signature of cell-susceptibility where APOE and SLC1A2 play a key role.
