Expression data from macaque taste buds and lingual epithelium

ABSTRACT: Efforts to unravel the mechanisms underlying taste sensation (gustation) have largely focused on rodents. The first comprehensive database of gene expression in primate (Macaca fascicularis) taste buds is presented. This database provides a foundation for further studies in diverse aspects of taste biology. A taste bud gene expression database was generated using laser capture microdissection (LCM) of tissue freeze medium OTC embedded macaque tongue tissue blocks. We collected fungiform (FG) taste buds at the front of the tongue, circumvallate (CV) taste buds at the back of the tongue, as well as non-gustatory lingual epithelium (LE). Gene expression was also analyzed in the top and bottom portions of CV taste buds collected using LCM. Samples were collected from 10 animals - 7 female, 3 male.

The single-cell RNA sequencing for α-gustducin-positive taste cells

Project description:Taste buds are complex sensory organs that are embedded in the epithelium of fungiform papillae (FP) and circumvallate papillae (CV). The sweet, bitter, and umami taste are sensed by type II taste cells that expressed taste receptors (Tas1rs and Tas2rs) which coupled with taste G-protein α-gustducin. Recent studies revealed that the taste response profiles of α-gustducin-expressing cells are different between FP and CV. We applied the high-throughput single-cell RNA-sequencing combined with fluorescence-activated cell sorting (FACS) to profile the transcriptome of the α-gustducin-expressing taste cells in both fungiform and circumvallatae papillae with transgenic mice expressing green fluorescent protein (GFP).

High Sox2 expression predicts taste lineage competency of lingual progenitors in vitro

Project description:Taste buds on the tongue are collections of taste receptor cells (TRCs) that detect sweet, sour, salty, umami and bitter stimuli. Like non-taste lingual epithelium, TRCs are renewed from basal keratinocytes, many of which express the transcription factor SOX2. Genetic lineage tracing has shown SOX2+ lingual progenitors give rise to both taste and non-taste lingual epithelium in the posterior circumvallate taste papilla (CVP) of mice. However, SOX2 is variably expressed among CVP cells suggesting that their progenitor potential may vary. Using transcriptome analysis and organoid technology, we show highly expressing SOX2+ cells are taste-competent progenitors that give rise to organoids comprising both TRCs and lingual epithelium, while organoids derived from low-expressing SOX2+ progenitors are composed entirely of non-taste cells. Hedgehog and WNT/ß-catenin are required for taste homeostasis in adult mice, but only WNT/ß-catenin promotes TRC differentiation in vitro and does so only in organoids derived from higher SOX2+ taste lineage-competent progenitors.

Single cell mRNA sequencing on esophageal and lingual cells

Project description:In this study, we uncovered through single cell RNA sequencing (scRNA-seq) of mouse esophagus epithelium a population of taste buds clustered in the cervical segment of the esophagus. We compared this taste bud population to their lingual counterpart. We concluded that these taste buds have the same cellular composition than the ones from the tongue. State-of-the-art transcriptional regulatory network analysis allowed the identification of specific transcription factors associated to the differentiation of immature progenitors into the three different taste bud cell types in the tongue and the esophagus.

The duct of von Ebner’s glands is a source of Sox10+ taste bud progenitors and susceptible to pathogen infections

Project description:We have recently demonstrated that Sox10-expressing (Sox10+) cells give rise to mainly type-III neuronal taste bud cells that are responsible for sour and salt taste. The two tissue compartments containing Sox10+ cells in the surrounding of taste buds include the connective tissue core of taste papillae and von Ebner’s glands (vEGs) that are connected to the trench of circumvallate and foliate papillae. Here we present data to support that it is the vEGs, not connective tissue core, that serve as the niche of Sox10+ taste bud progenitors. In this study, we performed single cell RNA-sequencing of the epithelium of Sox10-Cre/tdT mouse circumvallate/vEG complex and used inducible Cre mouse models to map the cell lineages of vEGs and/or connective tissue (including stromal and Schwann cells). Transcriptomic analysis indicated that Sox10 expression was enriched in the cell clusters of vEG ducts that contained abundant proliferating cells, while Sox10-Cre/tdT expression was enriched in type-III taste bud cells and vEG ductal cells. In vivo lineage mapping showed that the traced cells were distributed in circumvallate taste buds concurrently with those in the vEGs, but not in the connective tissue. Moreover, multiple genes encoding pathogen receptors were enriched in the vEG ducts hosting Sox10+ cells. If this is also true in humans, our data indicates that vEG duct is a source of Sox10+ taste bud progenitors and susceptible to pathogen infections.

Taste papilla cell differentiation requires the regulation of secretory protein production by ALK3-BMP signaling in the tongue mesenchyme

Project description:Taste papillae are specialized organs, each of which comprises an epithelial wall hosting taste buds and a core of mesenchymal tissue. In the present study, we report that during early taste papilla development in mouse embryos, bone morphogenetic protein (BMP) signaling mediated by type 1 receptor ALK3 in the tongue mesenchyme is required for the epithelial Wnt/β-catenin activity and taste papilla differentiation.

Tongue immune compartment analysis reveals spatial macrophage heterogeneity [bulk RNA-Seq]

Project description:The tongue is a unique muscular organ situated in the oral cavity where it is involved in taste sensation, mastication and articulation. As a barrier organ, which is constantly exposed to environmental pathogens,the tongue isexpected to host animmune cell network ensuringlocal immune defence. However, the composition and the transcriptional landscape of the tongue immune system are currently not completely defined. Here we characterised the tissue-resident immune compartment of the murine tongue during development, health anddisease, combining single cell RNA-sequencing with in situ immunophenotyping. We identified distinct local immune cell populations and described two specific subsets of tongue-resident macrophages occupying discrete anatomical niches. Cx3cr1+macrophages were located specifically in the highly innervated lamina propria beneath the tongue epidermis and at times in close proximity to fungiform papillae.Folr2+ macrophages were detected in deeper muscular tissue. The two macrophage subsets originate from a common proliferative precursor during early postnatal development and responded differently to systemic LPSin vivo. Our description of the under-investigated tongue immune system sets a starting point to facilitate research on tongue immune-physiology and pathology including cancer and taste disorders.

Developmental plasticity of epithelial stem cells in tooth and taste bud renewal

Project description:In Cichlids, replacement teeth (RT) share a continuous band of epithelium with adjacent taste buds (TB) and both organs co-express stem cell factors in subsets of label-retaining cells. In the mouse and other mammals, the tongue inter molar eminence (IE) oral papillae of Follistatin (Fat, BMP antagonist) mutants exhibited dysmorphic invagination. By using NGS-derived transcriptome profiling (RNAseq) analysis, we compared differential gene expression in the mouse tongue tissue in Follistatin (Fst) mutants mice with the wild type controls. Our results demonstrated ectopic expression of dental markers in tongue IE indicating that vertebrate oral epithelium retains inherent plasticity to form tooth and taste-like cell types mediated by BMP, therefore revealed under appreciated epithelial cell populations with promising potential in bioengineering and dental therapeutics.

Proteomic analysis of the mouse tongue proteome in response to western diet

Project description:The tongue is a heavily innervated and vascularized striated muscle that plays an important role in vocalization and swallowing. The surface of the tongue is lined with papillae which contain gustatory cells expressing various taste receptors. There is growing evidence to suggest our perceptions of taste and food preference are remodelled following chronic consumption of western diets rich in carbohydrate and fats. Our sensitivity to taste and also metabolism western diets may be a key factor in the rising prevalence of obesity but a systems-wide analysis is lacking. Here, we defined the proteomic landscape of the mouse tongue and quantified changes following chronic consumption of a chow or western diet for 7 months. We observed a dramatic remodelling of the tongue proteome including changes in fatty acid and mitochondrial metabolism. The expression of several receptors, and metabolic enzymes and hormones were also differentially regulated which is exciting as these may serve as novel therapeutic targets to potentially alter taste perception and food preference to combat obesity.

RNA-seq analysis of axolotl embryonic oropharyngeal endoderm explants transcriptome

Project description:The ability to taste is critical for animal nutrition and toxin deterrence. The majority of research on taste bud development and regeneration is in mice, where taste buds are located within specialized papillae on the tongue. However, taste buds in fish and amphibians, such as axolotls (Ambystoma mexicanum), are not housed in papillae, rather they are within the pharyngeal epithelium. This simplified tissue level organization, along with the ability of cultured oropharyngeal explants from early embryos to produce taste buds on the same time-line as embryos, make the axolotl an excellent model to identify molecules specifically involved in taste bud cell differentiation. In this study, we performed de novo transcriptomic analysis on RNA sequences from three different stages of oropharyngeal explants: stages 37/38, 39, and 41. RNA-seq data from 17 total samples representing these stages were pooled to generate de novo assemblie(s) of the transcriptome using a Trinity pipeline. Raw reads and the assembly were uploaded to Mendeley (doi:10.17632/tvxh3jm83m.1). From 27.9Gb of raw sequences, we identified 21,244 transcripts. To our knowledge, this study provides the first published assembly of axolotl oropharyngeal endoderm explants. This RNA-seq data and transcriptome assembly provide information on genes expressed in the oropharyngeal endoderm and will be valuable in the identification of taste bud development genes.
