We also measured transcript levels of the reactive astrocyte marker GFAP since cortical astrogliosis may exist in a subset of people with schizophrenia (Webster et al., 2005; Feresten et al., 2013; Catts et al., 2014; Toker et al., 2018; Murphy et al., 2020a) and reactive astrocytes reciprocally influence microglia polarization states (Jha et al., 2019; Corsi-Zuelli and Deakin, 2021). The gene discussed is GFAP; the disease is schizophrenia.
