摘要

We found that substance P (SP) and calcitonin gene-related peptide (CGRP) (0.3-1 microM) increased, in a concentration-dependent manner, the basal secretion of interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF alpha) from cultured lymphocyte-enriched mononuclear cells isolated from human peripheral blood. SP and CGRP (0.1 microM) synergistically increased basal TNF alpha secretion. Dynorphin A((1-17)) (0.1-1 microM) did not modify basal cytokine secretion. Lipopolysaccharide (10 ng/ml)-induced cytokine secretion and [(3)H]thymidine uptake were not altered by any neuropeptide (at 0.1 microM). Thus, SP and CGRP stimulate the production of pro-inflammatory cytokines from lymphocytes only at high concentrations, similar to those reached during tissue damage.
