Substance P (SP) is a prototypical neuropeptide with roles in pain and inflammation. Numerous mechanisms regulate endogenous SP levels, including the differential expression of SP mRNA and the controlled secretion of SP from neurons. Proteolysis has long been suspected to regulate extracellular SP concentrations but data in support of this hypothesis is scarce. Here, we provide evidence that pr...
Measles virus (MV) encodes the fusion protein (F) that mediates cell fusion and intercellular spread of the virus, and is homologous to the carboxy terminus of the neuropeptide substance P (SP). In addition, the oligopeptide Z-D-Phe-L-PheGly, also homologous to F and SP, inhibits MV fusion with target cells. These observations raise the question of whether MV uses the SP receptor (SPR) during a...
Much evidence suggests a cross-talking between nerve fibers and the immunity system. The immunomodulation by substance P includes cell activation and proliferation of human cells, with cytokine and chemokine generation and release. Substance P was first isolated by Leeman et al. as an undecapeptide with important neurotransmitter-neuromodulator effects. In addition, substance P was shown to ind...
