IL-1β levels are elevated in patients with neuropathic pain. As IL-1β was shown to be the key mediator in P2X7R-pain interplay, we analyzed serum levels of this pro-inflammatory and pro-nociceptive cytokine by multiplex immune assay. Affirmatively to the results with elevated P2X7Rs, we solely found significant increased serum levels in the peripheral blood of patients with NeP *p < 0.05. Data are presented as mean ± SD, n = 19, *p < 0.05 in one-way ANOVA with multiple comparisons versus healthy volunteers (Holm-Sidak method)
