TABLE 4.
Co-expression ratios for cytosolic prostaglandin E synthase (cPGES)-positive taste cells and taste cell markers: gustducin (type II for bitter, sweet and umami), T1R3 (type II for sweet and umami) and carbonic anhydrase 4 (CA4, type III for sour) in mouse circumvallate (CV), and fungiform papillae (FP) in Figure 3.
| Taste papillae | Percentage (%) | Percentage (%) | ||||
| CV | cPGES/T1R3 | 43.1% | (112/260, n = 111) | T1R3/cPGES | 62.9% | (112/178, n = 111) |
| cPGES/Gustducin | 43.5% | (94/216, n = 80) | Gustducin/cPGES | 55.6% | (94/169, n = 80) | |
| cPGES/CA4 | 14.5% | (19/131, n = 96) | CA4/cPGES | 8.1% | (19/233, n = 96) | |
| FP | cPGES/T1R3 | 60.6% | (28/53, n = 20) | T1R3/cPGES | 49.1% | (28/57, n = 20) |
| cPGES/Gustducin | 52.9% | (27/51, n = 18) | Gustducin/cPGES | 54.0% | (27/50, n = 18) | |
| cPGES/CA4 | 14.3% | (6/42, n = 19) | CA4/cPGES | 12.2% | (6/49, n = 19) | |
(The number of protein A + B positive cells/that of protein B positive cells, n = the number of taste buds analyzed).
