Background: The cerebrospinal fluid-contacting nucleus (CSF-CN), distributes and localizes in the ventral periaqueductal central gray (PAG) of the brainstem, which may influence actual composition of the cerebrospinal fluid (CSF) for non-synaptic signal transmission via releasing or absorbing bioactive substance. TRPV1 has been found in both the peripheral and spinal within centres known for their role in pain detection, transmission and regulation, consistent with its role in pain. Therefore, it is speculated that the CSF-CN participate in pain modulation via the receptor TRPV1. The present study aimed to observe the TRPV1 expression and distribution in the CSF-CN of rat brain parenchyma, and to explore the effects of TRPV1 on the CSF-CN in neuropathic pain.
