Drosophila Vision Depends on Carcinine Uptake by an Organic Cation Transporter.
Recycling of neurotransmitters is essential for sustained neuronal signaling, yet recycling pathways for various transmitters, including histamine, remain poorly understood. In the first visual ganglion (lamina) of Drosophila, photoreceptor-released histamine is taken up into perisynaptic glia, converted to carcinine, and delivered back to the photoreceptor for histamine regeneration. Here, we ...
متن کاملHistamine Recycling Is Mediated by CarT, a Carcinine Transporter in Drosophila Photoreceptors
Histamine is an important chemical messenger that regulates multiple physiological processes in both vertebrate and invertebrate animals. Even so, how glial cells and neurons recycle histamine remains to be elucidated. Drosophila photoreceptor neurons use histamine as a neurotransmitter, and the released histamine is recycled through neighboring glia, where it is conjugated to β-alanine to form...
متن کاملHistamine uptake by human endometrial cells expressing the organic cation transporter EMT and the vesicular monoamine transporter-2.
Cellular reuptake of monoamines, which is mediated by cell membrane transporters, is followed by accumulation in vesicles by vesicular monoamine transporters (VMAT). The aim of this study was to demonstrate the presence of functional monoamine transporters with high affinity for histamine in human endometrial tissue, since histamine has been implicated as a paracrine signal during endometrial d...
متن کاملFunctional characteristics and tissue distribution pattern of organic cation transporter 2 (OCTN2), an organic cation/carnitine transporter.
We have demonstrated in the present study that novel organic cation transporter (OCTN) 2 is a transporter for organic cations as well as carnitine. OCTN2 transports organic cations without involving Na(+), but it transports carnitine only in the presence of Na(+). The ability to transport organic cations and carnitine is demonstrable with human, rat, and mouse OCTN2s. Na(+) does not influence t...
متن کاملInteraction of oral antidiabetic drugs with hepatic uptake transporters: focus on organic anion transporting polypeptides and organic cation transporter 1.
OBJECTIVE The uptake of drugs into hepatocytes is a key determinant for hepatic metabolism, intrahepatic action, their subsequent systemic plasma concentrations, and extrahepatic actions. In vitro and in vivo studies indicate that many drugs used for treatment of cardiovascular diseases (e.g., oral antidiabetic drugs, statins) are taken up into hepatocytes by distinct organic anion transporters...
