There are many different types of receptors; that have many different functions. Neuromics selection of receptor antibodies includes antibodies in the following families; GABA, Leptin, NMDA, Neuropeptide, Neurotensin, Opioid, 5HT Serotonin, Purinergic, TLRs, Semaphorins, mGluRs, Trks, G-protein coupled, and iGluRs. With a wide range of families come a large range of functions. In vertebrates, GABA acts as an inhibitory synapses in the brain. Neuropeptides are neuronal signaling molecules. Chemokine receptors play roles in development, homeostasis, inflammation and infection. Opioids are important targets in pain and addiction research. 5HT Serotonin are involved in regulation of mood and appetite and have various other functions in the CNS and PNS

Changes in expression of μ-opioid receptor (μOR), green fluorescent protein (GFP), and overlapping μOR immunoreactivity (-ir) with GFP in L3–L5 dorsal root ganglia at 4 weeks after topical hind paw infection with herpes simplex virus encoding the gene for the μOR in antisense (SGAMOR) or sense (SGMOR) direction relative to the cytomegalovirus promoter, or the viral control encoding β-galactosidase (SGZ). Compared with control SGZ infection, infection with SGAMOR decreases the percentage of μOR-ir neurons in the L3–L5 dorsal root ganglia. In contrast, infection with SGMOR increases the percentage of μOR-ir neurons in the L3–L5 dorsal root ganglia. Full publication: doi:10.1097/01.anes.0000299836.61785.79
