There is evidence for interactions between leptin and cholecystokinin in controlling food intake. Since cholecystokinin acts on vagal afferent neurones, we asked whether the leptin receptor was also expressed by these neurones. Primers for different forms of the leptin receptor were used in reverse transcriptase-polymerase chain reaction (RT-PCR) of rat and human nodose ganglia. RT-PCR yielded products corresponding to the long (functional) form as well as short forms of the rat leptin receptor. Moreover, RT-PCR revealed the long form of the leptin receptor in a human nodose ganglion. The identities of RT-PCR products were confirmed by sequencing. Primers corresponding to leptin itself did not give RT-PCR products in nodose ganglia. Immunocytochemical studies revealed leptin-receptor immunoreactivity in neuronal cell bodies. Many neurones co-expressed the leptin and cholecystokinin type A receptors, or leptin receptor and cocaine- and amphetamine-related transcript. We conclude that vagal afferent neurones that express the cholecystokinin type A receptor and cocaine- and amphetamine-related transcript, may also express the long form of the leptin receptor providing a neurochemical basis for observations of interactions between cholecystokinin and leptin.
