Class A serotonin (5-hydroxytryptamine) 2A (5-HT2AR) and class C metabotropic glutamate 2 receptors (mGluR2) are seven transmembrane receptors (7TMRs or G protein-coupled receptors – GPCRs) involved in multiple neuropsychiatric disorders including schizophrenia. Previous findings from our laboratory reported that 5-HT2AR and mGluR2 are dysregulated in the prefrontal cortex of patients suffering from this psychiatric condition, although 5-HT2AR’s expression was recovered in antipsychotic-medicated patients. Genome-wide association studies on schizophrenia reported that endosomal trafficking that regulates cell surface abundance of another 7TMR implicated in this disease (dopamine D2 receptor) can be altered. Ligand-activated receptors, including the …

Schizophrenia is a severe neuropsychiatric disorder that presents with diverse symptoms, some of which remain resistant to treatment. Increased risk of neurodevelopmental disorders such as schizophrenia has been observed following gestational infection in humans, leading to development of maternal immune activation (MIA) animal models. Increased density of the serotonin 5-HT2AR receptor (5-HT2AR), the primary target of hallucinogenic drugs and a key target of atypical antipsychotics, has been observed in postmortem antipsychotic-free prefrontal cortex samples from schizophrenia subjects, a change reflected in frontal cortex of adult MIA offspring. To model MIA, we administered 20 mg/kg i.p. of the viral mimetic poly-(I:C) …
