VEGFA and schizophrenia: Understanding the effects of Vegfa signaling on cortical interneurons is important, as it is expressed in neural and vascular cells in the fetal human brain (Virgintino et al. 2003), and because Vegfa polymorphisms and its downregulation in the prefrontal cortex have been implicated in schizophrenia (Fulzele and Pillai 2009; Gao et al. 2015), a neurodevelopmental disorder also associated with interneuron deficits (Murray et al. 2014; Inan et al. 2016).
