We were also puzzled by our results indicating that TNF‐α‐stimulated SCZ astrocytes promoted the upregulation of pathways associated with multiple neurodegenerative diseases, such as Alzheimer's (AD) and Parkinson's disease (Figure S5C,D and Table S6C,D), and decided to investigate whether reactive SCZ astrocytes could prompt these dysfunctional microglia to assume a molecular profile akin to those observed in such neurological disorders. The gene discussed is TNF; the disease is Alzheimer disease.
