Susceptibility and resilience to maternal immune activation are associated with differential expression of endogenous retroviral elements

Abstract

Endogenous retroviruses (ERVs) are ancestorial retroviral elements that were integrated into the mammalian genome through germline infections and insertions during evolution. While increased ERV expression has been repeatedly implicated in psychiatric and neurodevelopmental disorders, recent evidence suggests that aberrant endogenous retroviral activity may contribute to biologically defined subgroups of psychotic disorders with persisting immunological dysfunctions. Here, we explored whether ERV expression is altered in a mouse model Show more
