Purpose of the Study:
- To review the structure, classification, distribution, and signaling pathways of bitter taste receptors.
- To explore the relationship between bitter taste receptors and various diseases.
- To discuss the role of bitter taste receptor agonists in potential treatments.
Main Methods:
- Literature review of scientific publications on bitter taste receptors.
- Analysis of studies on receptor expression, function, and disease association.
- Synthesis of information on signaling pathways and agonist activity.
Main Results:
- Bitter taste receptors have diverse expression patterns beyond taste buds.
- They are implicated in regulating critical physiological functions across multiple systems.
- Receptors are linked to various pathological conditions, suggesting therapeutic potential.
Conclusions:
- Bitter taste receptors are multifunctional proteins with significant physiological roles.
- Their extra-gustatory distribution highlights their importance in systemic health.
