Article Synopsis
The study explored the cholinergic system in African naked mole-rats, particularly focusing on the M1 and M4 subtypes of muscarinic acetylcholine receptors.
A comparison of protein sequences revealed 95% similarity with house mice, indicating that naked mole-rats can express all five muscarinic receptor subtypes.
Pain relief was observed in mole-rats after treatment with specific receptor agonists, suggesting that these receptors play a significant role in reducing pain.
