Although expression of TNFR1 in astrocytes has not been found in other central nervous system (CNS) disorders, astrocytes express FAS in inflammatory-related neurodegenerative diseases such as Alzheimer’s disease (72), Parkinson’s disease (73), Huntington’s disease (73), and autoimmune encephalitis (74), similar to what we found here in schizophrenia and bipolar disorder. Here, TNFRSF1A is linked to Parkinson disease.
