10. СМАКОВІ РЕЦЕПТОРИ
• TAS1R (3 типи): солодке та умамі (ліганди –
цукри та глутамат)
• TAS2R (50 типів): гірке (ліганди –алкалоїди та
біофлавоноїди)
• PKD2L1: кисле (Са2+ канали, які активуються
Н+)
• ENaC: солоне (канали для іонів Na+)
• GPR40, GPR120, GPR119: жирні кислоти

Extracellular recording system to trap adenosine triphosphate (ATP) released from a taste bud cell of α-gustducin–green fluorescence protein (Gust-GFP) mice. A: merged confocal and differential interference contrast images around the stimulating pipette tip with a fungiform taste bud in the experimental setup. B: sample records from a GFP-positive taste bud cell. NaCl, 300 mM; saccharin (Sac), 20 mM; HCl, 10 mM; cyclohexamide (Chx), 500 μM; monosodium glutamate (MSG), 300 mM. C: representative ATP release from a GFP-positive (a) and -negative (b) taste bud cell by application of 20 mM Sac. Left: extracellular recording of electrical activity (arrowheads indicate offset of bath perfusion and onset of taste stimulation). Right: ATP concentration in the recording electrode solution measured by luciferase assay (N.D., not detectable; detection limit, 40 pM).
