Purinergic Receptors in the Circumvallate Papillae of Rats
<p>P2X2 receptors and P2Y4 receptors are ATP-activated cell surface receptors that gate movement of K+, Na+, and Ca2+. We used immunocytochemistry for P2X2 and P2Y4 receptors as well as taste cell type markers to learn if P2X2 immunoreactivity (IR) is present in nerve processes in close apposition …

Generating hair follicle inductive dermal papillae cells from adipose derived mesenchymal stem cells
… of de novo folliculogenesis by generating dermal papillae (DP) like-spheroids using adipose derived mesenchymal stem cells (ASCs) that, when combined with responsive epithelial cells, would be capable of inducing hair follicle formation. ASCs were directed towards a hair follicle DP-like fate by …

Peripheral Taste System in Inbred Mouse Strains
… to be tasters have a larger number of fungiform papillae, have larger fungiform papillae and have larger taste buds. My work in this study involved counting the number of fungiform papillae from male and female of each strain, utilizing green food dye under light microscopy. I also utilized a …

Gross and Microscopic Observations on the Lingual Structure of the West Indian Manatee (Trichechus manatus latirostris)
… tip was free and mobile. Numerous filiform papillae were distributed over the dorsal surface of the rostral lingual region. Caudal to the filiform papillae, multiple raised, round papillae were distributed over the majority of the dorsum. Fungiform papillae were restricted to the lateral …

Impact of environmental and genetic factors on pain sensitivity and chronic pain development
… revealed the development of putative dermal papillae within 24 hours, with papillae numbers peaking on post-surgical day two. Ordinarily, dermal papillae house Meissner’s corpuscles, specialised nerve endings responsible for sensing dynamic touch which are implicated in dynamic mechanical …

Multinuclear and Mononuclear Polyploidy in the Drosophila Hindgut and Heart
… dissertation, I identify the Drosophila rectal papillae as a new model to study tissue interconnectivity, multinuclearity, and the interaction between nuclear content and cytoplasm-sharing. I played a major role in the discovery that the adult Drosophila rectal papillae share cytoplasm and …

Dopamine-Beta-Hydroxylase and Norepinephrine Transporter Immunoreactivity in Rat Taste Buds
… present in taste cells of the rat circumvallate papillae. Specifically, DBH–LIR is present in a subset of Type II taste cells. Nearly all (98%) DBH–LIR cells express PLCβ2–LIR, and about half (41%) of PLCβ2–LIR cells express DBH–LIR. DBH–LIR does not co–localize with NCAM, and thus, is not …

Taste physiological mechanisms and their health implications, analyzed by genetic, epigenetic, and artificial intelligence analyses
… reliable and automatic detection of fungiform papillae, overcoming the limitations of the manual method. On the molecular level, we demonstrated that methylation of the Gustin gene influences salivary protein levels and fungiform papillae density, while methylation of the TAS2R38 gene is …

EXPRESSION AND MISEXPRESSION OF THE MIR-183 FAMILY IN THE DEVELOPING HEARING ORGAN OF THE CHICKEN
… on the superior side in the base of the basilar papillae with undifferentiated precursors. At E12-E18, the higher packing density of tall hair cells located on the superior basilar papilla suggested the persistence of a radial gradient from the surface view. However, sections through the basilar …

Elucidation of the epithelial sodium channel as a salt taste receptor candidate and search for novel salt taste receptor candidates
… ion channels are likely in TBC of circumvallate papillae, possibly mediating basolateral sodium entry. Similarly, basolateral βγ-ENaC might play a role in fungiform TBC. Strikingly, δ-ENaC subunit was confined to taste bud pores of both papillae, likely mediating gustatory sodium entry in TBC, …

Effects of autolyzed yeast (saccharomyces cerevisiae) on feed degradability and digestibility; performance, rumen environment, and physiological biomarkers of Holstein cows fed a high starch diet
… on d 19 through 21 of each period. Rumen papillae and liver biopsies were conducted on d 21 of each period. One single degree-of-freedom contrast LS0 compared to HS0 was used, and linear, quadratic, and cubic treatment effects of HS0, HS15, HS30, and HS45 for statistical inferences. Cows …

Systematic revision of the South American armored catfish genus Loricaria (Siluriformes: Loricariidae)
