In addition they discovered that neuropathic pain hypersensitivity noticed in H4 receptor‐KO mice is related with an overactivation in the spinal ERK– pathway in DβH immunoreactive neurons, supporting a possible Affiliation involving the noradrenergic process and H4 receptor‐mediated analgesia. In summary, increasing evidence arising from H4 receptor KO mice https://josepht639qgw5.shivawiki.com/user
