Cytokine regulation in animal models of neuropathic pain and in human diseases
N Üçeyler, C Sommer - Neuroscience letters, 2008 - Elsevier
Cytokines are soluble proteins secreted mainly by immune cells and are key players in the
induction and maintenance of pain. Pro-inflammatory cytokines are mostly algesic, while anti …

Neuropathic pain and cytokines: current perspectives
AK Clark, EA Old, M Malcangio - Journal of pain research, 2013 - Taylor & Francis
Neuropathic pain represents a major problem in clinical medicine because it causes

Pain and the immune system: friend or foe?
HL Rittner, A Brack, C Stein - Der Anaesthesist, 2002 - europepmc.org
When tissue is destroyed, pain arises. Tissue destruction as well as wound healing are
associated with an inflammatory reaction. This leads to activation of nociceptors (" pain …
