Acupoints (Xuewei) are the focus of acupuncture on the body in traditional Chinese medicine treatment. Mast and nerve cells share a perivascular location and are abundantly found at these acupoints. Both environmental factors and medical treatments (chemical and physical stimuli) can stimulate local mast cells (MCs) to degranulate and thus release histamine which then activates the nearby nerves and therefore contributes to a signal transmission from the peripheral to the central nervous system. In this paper, a mathematical model is constructed to describe the signaling pathways that originate from the cells located at an acupoint. We show that: (1) peripheral stimuli induce the release of histamine from MCs; (2) histamine excites receptors in primary sensory neurons and leads to membrane action potentials; (3) histamine released from MCs at an acupoint plays a key role in response to acupuncture. These results are consistent with experimental observations. Furthermore, this study may facilitate our understanding of the signal transmission process that occurs in response to peripheral stimuli as well as provide a useful modeling tool for quantitatively analyzing immune and acupuncture mechanisms that involve MCs.
