SERPINF1 and schizophrenia: Taken together mentioned-above cross-sectional and longitudinal changes in sTNFR1 and PEDF levels in schizophrenia, we hypothesized that; while all patients with schizophrenia were initially treated with medication on admission, it was noted that patients not taking medications, including drug-naïve patients and those with relapse, had low PEDF levels (Figure 1M), but similar sTNFR1 levels (Figure 1J) when compared with healthy controls.
