Three types of tachykinin receptors, namely NK1, NK2 and NK3, are known to preferentially interact with substance P (SP), neurokinin A (NKA) and neurokinin B (NKB), respectively. Experimental evidence indicates that SP and NKA modulate the activity of inflammatory and immune cells, including mononuclear ones. This study evaluated the effects of mammalian tachykinins and selective tachykinin agonists and antagonists on human monocytes isolated from healthy donors: SP, NKA and NKB all evoked a dose-dependent superoxide anion (O2-) production and the NK2 selective agonist [beta-Ala8]-NKA(4-10) induced a full response. The NK3 selective agonist senktide was inactive, while the NK1 selective agonists septide and [Sar9Met(O2)11]SP displayed some effects. These results indicate that NK2 and also some NK1 receptors are present in monocytes isolated from healthy donors. The role of tachykinin receptor activation in rheumatoid arthritis was also investigated, by measuring O2- production and TNF-alpha mRNA expression in monocytes isolated from rheumatoid patients. Tachykinins enhanced the expression of this cytokine in both control and rheumatoid monocytes and NK2 receptor stimulation was shown to trigger an enhanced respiratory burst in monocytes from rheumatoid patients. In conclusion, these results indicate that NK2 and NK1 receptors are present on human monocytes, the former being preferentially involved in rheumatoid arthritis.
