Fumie Hirose, Shingo Takai, Ichiro Takahashi, Noriatsu Shigemura, Expression of protocadherin-20 in mouse taste buds, Scientific reports, 10.1038/s41598-020-58991-8, 10, 1, 2020.12, Taste information is detected by taste cells and then transmitted to the brain through the taste nerve fibers. According to our previous data, there may be specific coding of taste quality between taste cells and nerve fibers. However, the molecular mechanisms underlying this coding specificity remain unclear. The purpose of this study was to identify candidate molecules that may regulate the specific coding. GeneChip analysis of mRNA isolated from the mice taste papillae and taste ganglia revealed that 14 members of the cadherin superfamily, which are important regulators of synapse formation and plasticity, were expressed in both tissues. Among them, protocadherin-20 (Pcdh20) was highly expressed in a subset of taste bud cells, and co-expressed with taste receptor type 1 member 3 (T1R3, a marker of sweet- or umami-sensitive taste cells) but not gustducin or carbonic anhydrase-4 (markers of bitter/sweet- and sour-sensitive taste cells, respectively) in circumvallate papillae. Furthermore, Pcdh20 expression in taste cells occurred later than T1R3 expression during the morphogenesis of taste papillae. Thus, Pcdh20 may be involved in taste quality-specific connections between differentiated taste cells and their partner neurons, thereby acting as a molecular tag for the coding of sweet and/or umami taste..

Osaki A, Sanematsu K, Yamazoe J, Hirose F, Watanabe Y, Kawabata Y, Oike A, Hirayama A, Yamada Y, Iwata S, Takai S, Wada N, Shigemura N, Drinking Ice-cold Water Reduces the Severity of Anticancer Drug-induced Taste Dysfunction in Mice, Int J Mol Sci., 10.3390/ijms21238958, 21, (23), 8958, 2020.11, Taste disorders are common adverse effects of cancer chemotherapy that can reduce quality of life and impair nutritional status. However, the molecular mechanisms underlying chemotherapy-induced taste disorders remain largely unknown. Furthermore, there are no effective preventive measures for chemotherapy-induced taste disorders. We investigated the effects of a combination of three anticancer drugs (TPF: docetaxel, cisplatin and 5-fluorouracil) on the structure and function of mouse taste tissues and examined whether the drinking of ice-cold water after TPF administration would attenuate these effects. TPF administration significantly increased the number of cells expressing apoptotic and proliferative markers. Furthermore, TPF administration significantly reduced the number of cells expressing taste cell markers and the magnitudes of the responses of taste nerves to tastants. The above results suggest that anticancer drug-induced taste dysfunction may be due to a reduction in the number of taste cells expressing taste-related molecules. The suppressive effects of TPF on taste cell marker expression and taste perception were reduced by the drinking of ice-cold water. We speculate that oral cryotherapy with an ice cube might be useful for prophylaxis against anticancer drug-induced taste disorders in humans..

8. Jihye Park, Balaji Selvam, Keisuke Sanematsu, Noriatsu Shigemura, Diwakar Shukla, Erik Procko, Structural architecture of a dimeric class C GPCR based on co-trafficking of sweet taste receptor subunits, Journal of Biological Chemistry, 10.1074/jbc.RA118.006173, 294, 13, 4759-4774, 2019.03, Class C G protein– coupled receptors (GPCRs) are obligatory dimers that are particularly important for neuronal responses to endogenous and environmental stimuli. Ligand recognition through large extracellular domains leads to the reorganization of transmembrane regions to activate G protein signaling. Although structures of individual domains are known, the complete architecture of a class C GPCR and the mechanism of interdomain coupling during receptor activation are unclear. By screening a mutagenesis library of the human class C sweet taste receptor subunit T1R2, we enhanced surface expression and identified a dibasic intracellular retention motif that modulates surface expression and co-trafficking with its heterodimeric partner T1R3. Using a highly expressed T1R2 variant, dimerization sites along the entire subunit within all the structural domains were identified by a comprehensive mutational scan for co-trafficking with T1R3 in human cells. The data further reveal that the C terminus of the extracellular cysteine-rich domain needs to be properly folded for T1R3 dimerization and co-trafficking, but not for surface expression of T1R2 alone. These results guided the modeling of the T1R2–T1R3 dimer in living cells, which predicts a twisted arrangement of domains around the central axis, and a continuous folded structure between transmembrane domain loops and the cysteine-rich domains. These insights have implications for how conformational changes between domains are coupled within class C GPCRs..

Margolskee, Peihua Jiang, Ikiru Atsuta, Kiyoshi Koyano, Yuzo Ninomiya, Noriatsu Shigemura, Effects of insulin signaling on mouse taste cell proliferation, PloS one, 10.1371/journal.pone.0225190, 14, 11, 2019.01, Expression of insulin and its receptor (IR) in rodent taste cells has been proposed, but exactly which types of taste cells express IR and the function of insulin signaling in taste organ have yet to be determined. In this study, we analyzed expression of IR mRNA and protein in mouse taste bud cells in vivo and explored its function ex vivo in organoids, using RT-PCR, immunohistochemistry, and quantitative PCR. In mouse taste tissue, IR was expressed broadly in taste buds, including in type II and III taste cells. With using 3-D taste bud organoids, we found insulin in the culture medium significantly decreased the number of taste cell and mRNA expression levels of many taste cell genes, including nucleoside triphosphate diphosphohydrolase-2 (NTPDase2), Tas1R3 (T1R3), gustducin, carbonic anhydrase 4 (CA4), glucose transporter-8 (GLUT8), and sodium-glucose cotransporter-1 (SGLT1) in a concentration-dependent manner. Rapamycin, an inhibitor of mechanistic target of rapamycin (mTOR) signaling, diminished insulin’s effects and increase taste cell generation. Altogether, circulating insulin might be an important regulator of taste cell growth and/or proliferation via activation of the mTOR pathway..

3. Noriatsu Shigemura, Taste perception and food intake, 86th Annual meeting of the Japanese Pharmalogical Society, 2013.03, Information derived from taste receptor cells, such as sweet, bitter, salty, sour and umami is important for evaluating the quality of food components. Modulation of the gustatory information influences food preference and intake. Even so, the molecular mechanisms for modulating taste sensitivity are poorly understood. Our recent studies have demonstrated that sweet and salty taste sensitivities are affected by hormones. Angiotensin II (AngII), which plays important roles in the maintenance of sodium homeostasis by acting on AngII type 1 receptor in various organs including brain and kidney, modulates peripheral salt and sweet taste sensitivities, and this modulation influences ingestive behavior in mice. Leptin (an anorexigenic mediator) and endocannabinoids (orexigenic mediators), which reciprocally regulate food intake via central nervous systems, modulate palatability of foods by altering sweet taste responses. Thus peripheral modulations of taste information by these hormones critically influence food intake, and may play important roles in regulating sodium and energy homeostasis. Understanding basic principles about these taste modulations may lead us to design novel strategies to maintain and improve the quality of life in patients with medical treatment..
