Abstract EN

Infection with the protozoan parasite, Toxoplasma gondii (T.

gondii), was linked to several psychiatric disorders.

The exact mechanisms of a hypothesized contribution of T.

gondii infection are poorly understood, and it appears that only a subset of seropositive individuals go on to develop a mental illness, suggesting genetic vulnerability.

In order to stimulate mechanistic studies of how exposure to T.

gondii could interact with genetic predisposition to psychiatric disorders, we have generated and characterized a mouse model of chronic T.

gondii infection in BALB/c mice with inducible forebrain neuronal expression of a C-terminus truncated dominant-negative form of disrupted-in-schizophrenia 1 (DN-DISC1).

In this gene-environment interaction (GxE) model, exposing control and DN-DISC1 male and female mice to T.

gondii produced sex-dependent abnormalities in locomotor activity and prepulse inhibition of the acoustic startle.

No genotype- or sex-dependent effects were found on levels of anti-Toxoplasma IgG antibodies or anti-NMDAR or C1q antibodies.

Our work demonstrates that a psychiatric genetic risk factor, DN-DISC1, modulates the neurobehavioral effects of chronic T.

gondii infection in a sex-dependent manner.

The present T.

gondii model of GxE provides a valuable experimental system for future mechanistic studies and evaluation of new treatments.
