A protocol for establishing a male G×E schizophrenia mouse model.

Abstract

Schizophrenia pathogenesis involves both genetic and environmental factors (G×E). Here, we present a protocol to prepare a schizophrenia rodent model with a specific G×E pair. We describe the breeding of Bdnf-e6-/- mice with genetic deficiency in promoter-VI-driven BDNF expression. We then detail the procedure to expose the mice to postnatal environmental stress including hypoxia, social isolation, and corticosterone. This model better represents the etiology of schizophrenia and thus may facilitate basic research and drug development for schizophrenia. For complete details on the use and execution of this protocol, please refer to Chen et al. (2022)..
