Summary: | Sensory processing dysfunction (SPD) is present in most patients with intellectual disability (ID) and autism spectrum disorder (ASD). Silencing expression of the Fragile X mental retardation 1 (
) gene leads to Fragile X syndrome (FXS), the most common single gene cause of ID and ASD.
have a highly conserved FMR1 ortholog,
.
mutants display cognitive and social defects reminiscent of symptoms seen in individuals with FXS. We utilized a robust behavioral assay for sensory processing of the
stress odorant (dSO) to gain a better understanding of the molecular basis of SPD in FXS. Here, we show that
mutant flies present significant defects in dSO response. We found that
expression in mushroom bodies is required for dSO processing. We also show that cyclic adenosine monophosphate (cAMP) signaling via PKA is activated after exposure to dSO and that several drugs regulating both cAMP and cyclic guanosine monophosphate (cGMP) levels significantly improved defects in dSO processing in
mutant flies. |
