Paracetamol inhibits nitric oxide synthesis in murine spinal cord slices.
Paracetamol is an effective analgesic but its mechanism of action is unclear. We investigated the effect of paracetamol and the analgesic adjuvant caffeine on the activity of NO synthase in mouse spinal cord and cerebellar slices in vitro, by measuring the conversion of [(3)H]arginine to [(3)H]citrulline. Paracetamol (100 microM) had no effect on NO synthase activity in cerebellum, but in the s...
متن کاملPain Modulation by Nitric Oxide in the Spinal Cord
Nitric oxide (NO) is a versatile messenger molecule first associated with endothelial relaxing effects. In the central nervous system (CNS), NO synthesis is primarily triggered by activation of N-methyl-D-aspartate (NMDA) receptors and has a Janus face, with both beneficial and harmful properties. There are three isoforms of the NO synthesizing enzyme nitric oxide synthase (NOS): neuronal (nNOS...
متن کاملNitric oxide inhibits viral replication in murine myocarditis.
Nitric oxide (NO) is a radical molecule that not only serves as a vasodilator and neurotransmitter but also acts as a cytotoxic effector molecule of the immune system. The inducible enzyme making NO, inducible NO synthase (iNOS), is transcriptionally activated by IFN-gamma and TNF-alpha, cytokines which are produced during viral infection. We show that iNOS is induced in mice infected with the ...
متن کاملEndotoxin-mediated nitric oxide synthesis inhibits IL-1β gene transcription in ANA-1 murine macrophages.
On the basis of previous work demonstrating nitric oxide (NO)-mediated inhibition of nuclear factor-κB (NF-κB) DNA binding, we hypothesized that NO downregulates NF-κB-dependent interleukin-1β (IL-1β) production in an ANA-1 macrophage model of lipopolysaccharide (LPS) stimulation. In the presence of LPS (100 ng/ml), levels of IL-1β protein and mRNA were significantly upregulated with NO synthas...
