MAPT and Alzheimer disease: Finally, ferroptosis-related genes deregulation in glial cells seems to be associated with later stages of tau-associated AD pathology, as not only more DEGs could be observed with increased pathology, reflected by a higher Braak stage, but also more cell types were affected by AD pathology (number of DEGs in 0 vs. 2 < 0 vs. 6 and 0 vs. 2 < 2 vs. 6).
