| Abstract: | © 2020 Elsevier B.V. The apolipoprotein E (APOE) ε4 allele hastens cognitive decline, but other non-cognitive behaviours, as well as underpinning interactions with the cholinergic system, have not been systematically addressed. Both C57BL/6 and humanised apoE4 female mice were transiently exposed to subclinical doses (0 or 1 mg/kg body weight) of the cholinesterase inhibitor chlorpyrifos (CPF), a widely-used pesticide, from postnatal days 10–15. At 5 months of age, we assessed the impact of APOE4 genotype, postnatal CPF exposure and APOE4 x CPF interactions on anxiety (open field and light-dark tests), stereotypes (digging test) and neophobia (sucrose preference test), as well as on high-fat diet (HFD)-seeking and consumption (scheduled-feeding paradigm). We found that control APOE4 female carriers displayed a robust anxiety-like phenotype, which was accompanied by exaggerated stereotypes and a subtle neophobic response to rewarding foods. In parallel, we observed an amplified “wanting” response for HFD in these mice, which did not entail enhanced “liking”. Notably, postnatal CPF ameliorated the anxiety-like and the heightened HFD-seeking responses in adult apoE4 female mice, while caused them to gain weight steadily compared to control peers. In turn, an early-life transient exposure to CPF fostered the over-consumption of HFD during adulthood without affecting how much this reward was “wanted” or the total caloric intake. These data reveal a role for CPF towards fostering “unhealthy” dietary choices. We conclude that the APOE4 genotype modulates non-cognitive behaviours and we provide support for an APOE4-dependent cholinergic dysfunction. |
