The Really Important Reason Your Lungs Have Taste Receptors

Taste receptors, initially thought to only detect flavors, are found in various body parts like the lungs, playing roles in pathogen defense. Bitter taste receptors (T2Rs) show genetic variability, affecting taste perception and susceptibility to respiratory infections. These receptors may influence health conditions like COPD and asthma, suggesting broader functions beyond taste.

What evidence suggests that taste receptors are involved in respiratory health?

Why might it be misleading to refer to T2Rs as taste receptors?
