Studies in Pink1 deficient mice have also identified links between dysregulation of mitophagy, cellular stress responses and anxiety (Agnihotri et al., 2019; Duan et al., 2021; Li et al., 2024) and several studies in Pink1–/–rats have identified gene impacts on behavioral measures of anxiety in open field, light/dark box and elevated plus maze testing (Cai et al., 2019; Hoffmeister et al., 2022; Lechner et al., 2022; Marquis et al., 2020).
