GABBR2 and infection: Other genes implicated in the regulation of odor-mediated behavior in insects, including those involved in neurotransmitter, neuropeptide and biogenic amine signaling (S3 Fig), were reliably detected, with only the CG10702/Insulin-like neuropeptide receptor, the neurotransmitter receptor GABA-B-R2, the ion transport peptide AAEL019725, and the biogenic amine receptor Oct-3R being differentially abundant across different infection states (Fig 5A).
