Sur la piste du « goût du gras »
2006
Sense of taste informs the body about the quality of ingested foods. Five sub-modalities allowing the perception of sweet, salty, sour, bitter, and umami stimuli are classically depicted in Human. However, the spontaneous attraction of mammals for fatty foods raises the possibility of an additional oro-sensory modality devoted to the fat perception. During a long time, oro-sensory perception of dietary lipids was thought to take place only through textural and retronasal olfactory cues. This minireview analyses recent findings showing that the gustation can also play a significant role in the dietary lipid perception.
Ultrastructural comparative analysis on the adhesive papillae of the swimming larvae of three ascidian species
2009
This paper presents a preliminary report on the papillae of the swimming larvae of three ascidian species: Ascidia malaca, Phallusia mammillata and Ciona intestinalis. The investigations, carried out at ultrastructural level and at confocal laser microscope, have evidenced, in the adhesive papillae of the three studied species, three different cell-types: axial columnar cells, collocytes, sensory cells respectively. The adhesive papillae of A. malaca and P. mammillata show central axial columnar cells with long microvilli emerging from the apical edge and extending throughout the hyaline cap. Collocytes are elongated secreting cells, lying in middle-lateral side. Sensory cells have a cilium…
