Polycystic kidney disease 1-like 3 (Pkd1l3) is expressed specifically in sour-sensing type III taste cells that have synaptic contacts with afferent nerve fibers in circumvallate (CvP) and foliate papillae (FoP) located in the posterior region of the tongue, although not in fungiform papillae (FuP) or the palate. To visualize the gustatory neural pathways(More)
The polycystic kidney disease 1-like 3 (PKD1L3) and polycystic kidney disease 2-like 1 (PKD2L1) proteins have been proposed to form heteromers that function as sour taste receptors in mammals. Here, we show that PKD1L3 and PKD2L1 interact through their transmembrane domains, and not through the coiled-coil domain, by coimmunoprecipitation experiments using(More)
Vertebrate cryptochrome homologs (CRYs) are negative regulators for the transcription/translation-based autoregulatory feedback loop of the circadian clock. In this study we identified two Cry genes in the chicken, cCry1 and cCry2, which are expressed in the pineal gland. Messenger RNA levels of both cCry1 and cCry2 displayed circadian oscillation in(More)
The electrophysiological effects of KST-5452 [3-(m-phenoxybenzylidene)-quinuclidine], an M1 muscarinic acetylcholine receptor (muscarinic AChR) binding compound, were studied in NG108-15 neuroblastoma x glioma hybrid cells transfected with m1 muscarinic AChR cDNA. Application of KST-5452 to m1-transformed NGPM1-27 cells elicited a sustained inward current(More)
Taste cells release neurotransmitters to gustatory neurons to transmit chemical information they received. Sweet, umami, and bitter taste cells use ATP as a neurotransmitter. However, ATP release from sour taste cells has not been observed so far. Instead, they release serotonin when they are activated by sour/acid stimuli. Thus it is still controversial(More)
