  • Title: A metabolite of substance P, SP7-11 is involved in the pathogenesis of inflammatory joint disease.
    Author: Halliday DA, McNeil JD, Scicchitano R.
    Journal: Med Hypotheses; 1993 Apr; 40(4):227-31. PubMed ID: 7686613.
    Abstract:
    The possibility that neuropeptides, in particular members of the tachykinin family are involved in inflammatory joint disease is widely disputed. Both clinical and experimental observations indicate that the tachykinin substance P (SP) may be involved in the pathogenesis of arthritis. We have studied the effects of tachykinins and the metabolites of SP on chondrocyte function. We have shown that the C-terminal pentapeptide sequence; H-Phe-Phe-Gly-Leu-Met-NH2 is biologically active in bovine chondrocyte cultures. The production of SP7-11 is limited by hydrolysis of the intact peptide by neutral endopeptidase (E.C. 3.4.24.11). The regulation of this enzyme would modulate the activity of substance P on articular cartilage chondrocytes.
