Accumulating evidence indicates that various subtypes of purinergic receptors (P2X and P2Y receptor families) play an essential role in the development and the maintenance of neuropathic pain. However, there is only limited data available about the role of P2Y6 receptors in pain processing. Here we detected P2Y6 receptor immunoreactivity in primary afferent(More)
AMP-activated kinase (AMPK) is a cellular energy sensor, which is activated in stages of increased adenosine triphosphate (ATP) consumption. Its activation has been associated with a number of beneficial effects such as decrease of inflammatory processes and inhibition of disease progression of diabetes and obesity. A recent study suggested that salicylate,(More)
TANK-binding kinase (TBK1) is a non-canonical IκB kinase (IKK) involved in the regulation of type I interferons and of NF-κB signal transduction. It is activated by viral infections and inflammatory mediators and has therefore been associated with viral diseases, obesity, and rheumatoid arthritis. Its role in pain has not been investigated so far. Due to(More)
Inhibitor-kappaB kinase epsilon (IKKε) constitutes a non-canonical I-κB kinase, which amongst others modulates NF-κB activity. IKKε and NF-κB have both been described for their role in cell proliferation and their dysregulation has been associated with tumourigenesis and metastasis in multiple cancer types. Accordingly, overexpression and constitutive(More)
AMP-activated kinase is a cellular energy sensor which is activated in stages of increased ATP consumption. Its activation has been associated with a number of beneficial effects such as decreasing inflammatory processes and the disease progress of diabetes and obesity, respectively. Furthermore, AMPK activation has been linked with induction of cell cycle(More)
BACKGROUND Cancer pain is associated with increased pain sensitivity to noxious (hyperalgesia) and normally innocuous (allodynia) stimuli due to activation of nociceptors by tumour-derived mediators or tumour infiltration of nerves. The pain sensitization is accompanied by modifications in gene expression, but specifically regulated genes are largely(More)
The processing of pain undergoes several changes in aging that affect sensory nociceptive fibers and the endogenous neuronal inhibitory systems. So far, it is not completely clear whether age-induced modifications are associated with an increase or decrease in pain perception. In this study, we assessed the impact of age on inflammatory nociception in mice(More)
