This volume addresses neuronal pain mechanisms at the peripheral, spinal
and supraspinal level which are thought to significantly contribute to
pain and which may be the basis for the development of new treatment
principles. Chapters on nociceptive mechanisms in the peripheral
nociceptive system address the concept of hyperalgesic priming, the role
of voltage-gated sodium channels in different inflammatory and
neuropathic pain states, the hyperalgesic effects of NGF in different
tissues and in inflammatory and neuropathic pain states, and the
contribution of proteinase activated receptors (PAR) to the development
of pain in several chronic pain conditions. Chapters on nociceptive
mechanisms in the spinal cord address the particular role of NO and of
glial cell activation in the generation and maintenance of inflammatory
and neuropathic pain and it discusses the potential role of local
inhibitory interneurons, of the endogenous endocannabinoid system and
the importance of non-neuronal immune mechanisms in opioid signaling in
the control of pain. Furthermore, it is presented how spinal mechanisms
contribute to the expression of peripheral inflammation.
