The synthesis and release of collagenase in the presence of the neuropeptide substance P (SP) and capsaicin, were investigated in vitro using identical synoviocyte cultures from patients with rheumatoid arthritis (RA). On average 10(-12) M SP augmented statistically significantly the collagenase production by approximately a factor of five. An increase in the concentrations up to 10(-6) M SP resulted in a decreased collagenase synthesis, which, however, was still above the level of that of the… 

Effect of substance P and somatostatin on migration of polymorphonuclear (PMN) cells in vitro

Although it is uncertain whether in vivo SP and SOM contribute directly to the invasion of PMN cells into the joint cavity, the influence of these neuropeptides on PMN migration in vitro is a further indication of the neuropeptic involvement in the genesis of inflammation.

SUBSTANCE P UP-REGULATES MATRIX METALLOPROTEINASE-1 AND DOWN-REGULATES COLLAGEN IN HUMAN LUNG FIBROBLAST

Results suggest that substance P participates in extracellular matrix metabolism, and induced a decrease in collagen biosynthesis, concomitant to a down-regulation of pro-α1(I) collagen mRNA.

Different observations suggest that one approach to the treatment of RA might be to inhibit the local effects of neurokinins in the affected joints, and this review will summarise the more relevant aspects of this topic.

Microscopic localization of active gelatinases in equine osteochondritis dissecans (OCD) cartilage.

Investigating the relationship between matrix metalloproteinase (MMP) activity and osteochondritis dissecans (OCD) in the equine joint revealed MMP activity, especially in the deep zone adjacent to the calcified subchondral bone.

Expression of osteoclast differentiation factor in rheumatoid arthritis.

The present results suggest that activated RASF, by expressing ODF, play an important role in rheumatoid bone destruction and provide evidence that R ASF not only activate osteoclasts, but also contribute directly to osteoclastogenesis.

Effects of capsaicin on the metabolism of rheumatoid arthritis synoviocytes in vitro.

The results indicate that the different effects of capsaicin on cellular proliferation and on metabolic activities are dependent on dose and suggest that the responses seen in rheumatoid arthritis synoviocytes in vitro might not be mediated by tachykinins if the synovial tissue is still able to produce neuropeptides in the absence of neuronal afferents.

Production of collagenase and prostaglandins by isolated adherent rheumatoid synovial cells.

Production of PGE2 and collagenase in large amounts in vitro by cells dispersed with proteolytic enzymes from rheumatoid arthritic synovectomy specimens suggests that they may be involved in joint destruction in vivo.

Substance P activation of rheumatoid synoviocytes: neural pathway in pathogenesis of arthritis.

The specific stimulation of synoviocytes by the neuropeptide substance P represents a pathway by which the nervous system might be directly involved in the pathogenesis of rheumatoid arthritis.

Human recombinant interleukin 1 stimulates collagenase and prostaglandin E2 production by human synovial cells.

It is demonstrated that three biological properties of human monocyte-derived IL-1 (T-lymphocyte activation and human synovial cell prostaglandin E2 and collagenase production) co-purify.

Inhibition of carrageenan induced inflammation in the rat knee joint by substance P antagonist.

Results indicate a significant neurogenic component in this model of acute joint inflammation in animals whose knee had previously been injected with 1% capsaicin, while chronic joint denervation produced a 37% reduction.

Cachectin/tumor necrosis factor stimulates collagenase and prostaglandin E2 production by human synovial cells and dermal fibroblasts

The ability of cachectin/TNF to stimulate collagenase and PGE2 production suggests that it may play a role in tissue destruction and remodelling, as these processes occur in inflammatory diseases.

Mechanisms of depletion of substance P by capsaicin.

As the onset of thermal analgesia in guinea pigs precedes depletion of substance P, direct neural actions of capsaicin probably account for its effects on sensory function.

Induction of human interleukin 1 mRNA measured by collagenase‐ and prostaglandin E2‐stimulating activity in rheumatoid synovial cells

The mRNA of a member of the interleukin 1 family can now be studied in a system based on a specific and direct relevant biological assay and eventually compared with those of other monokines.
