p11 is an adaptor protein which binds to serotonin 5-HT1B receptors and 5-HT4 receptors and regulates their localization at the cell surface. In the present study, we examined to what extent pll containing neurons co-expressed 5-HT1BR and/or 5-HT4R in cerebral cortex, hippocampus, cerebellum and caudateputamen. A triple-labeling immunohistochemical approach was taken using antibodies to detect native p11 and 5-HT1BR combined with visualization of EGFP driven under the 5-HT4R promoter in BAC-transgenic mice. In the caudate-putamen, the hippocampal pyramidal cell layer of CA1 and the hippocampal granule cell layer of dentate gyrus, most pll containing cells co-expressed both 5-HT1BR and 5-HT4R. In the cingulate cortex, stratum radiatum/oriens of CA1, hilus of the dentate gyrus and cerebellar cortex, many cells co-expressed p11 and 5-HT1BR, but not 5-HT4R. In the studied brain regions, few cells solely expressed p11 without any significant expression of 5-HT1BR or 5-HT4R. It can be concluded that pll is anatomically positioned to modulate serotonin neurotransmission, via 5-HT1BR and 5-HT4R, in brain regions important for emotionality, cognition and locomotion.
