Among receptors we found for which expression was altered by parasite infection (Fig. 8) were beta-2 adrenergic receptor-like isoform X1, dopamine receptor and FMRFamide receptor, neuronal acetylcholine receptor subunit beta-4, QRFP-like peptide receptor, somatostatin receptor type 2 and neurogenic locus notch protein. Here, SSTR2 is linked to parasitic infectious disease.
