Matrix metalloproteinase-9 (MMP-9) activity is required for inflammatory response, leukocyte recruitment, and tumor invasion. There is increasing evidence suggesting that the P2X(7) receptor of mononuclear cells, which is activated by extracellular adenosine triphosphate (ATP), is involved in inflammatory responses. In this study, ATP caused a rapid release of MMP-9 and a moderate decrease in tissue inhibitor of metalloproteinase 1 (TIMP-1) release from human peripheral-blood mononuclear cells… 

Figures and Tables from this paper

Activation of the P2X7 receptor induces migration of glial cells by inducing cathepsin B degradation of tissue inhibitor of metalloproteinase 1

It is shown that ATP‐treated glial cultures from neonatal C57BL/6 mice release and increase MMP‐9 activity, which is coupled with a decrease in release of TIMP‐1 and an increase in activated cathepsin B within the extracellular space.

ATP induced microglial cell migration through non-transcriptional activation of matrix metalloproteinase-9

The results from the present investigation may provide further insights into the regulation of the activity of MMP-9 during microglial migration, which may play essential role in theregulation of inflammatory responses in pathological situations such as neurodegenerative disorders.

Sustained activation of P2X7 induces MMP-2-evoked cleavage and functional purinoceptor inhibition

It is demonstrated that P2X7 ablation eliminated gelatinase activity in inflamed dystrophic muscles in vivo and could be used as an alternative to highly toxic MMP inhibitors in treatments of inflammatory diseases and cancers.

P2X7 Receptor-Mediated Release of Cathepsins from Macrophages Is a Cytokine-Independent Mechanism Potentially Involved in Joint Diseases

P2X7R activation may play a novel and direct role in tissue damage through release of cathepsins independently of its proinflammatory actions via IL-1 cytokines.

The P2X7 Receptor in Inflammatory Diseases: Angel or Demon?

In neuroinflammatory and neurodegenerative diseases, P2X7 upregulation and function appears to contribute to disease progression, and is highlighted as a potential target to treat inflammatory related diseases.

The human P2X7 receptor and its role in innate immunity.

The many roles involving P2X7 suggest that this receptor is essential to fundamental aspects of the innate immune response, including shedding of certain surface molecules, membrane blebbing, microvesicle/exosome release and apoptosis of the cell.

Exogenous ATP modulates PGE2 release in macrophages through sustained phosphorylation of CDK9 and p38 MAPK

It is shown that eATP synergistically increases the levels of COX-2 enzyme and PGE2 in LPS-activated RAW264.7 macrophages and human monocytes and could be abolished using antagonists for purinergic P2X7 -and P2Y6 receptors.

P2X7 receptor regulates EMMPRIN and MMP‑9 expression through AMPK/MAPK signaling in PMA‑induced macrophages.

The inhibition of P2X7R may be able to suppress the AMPK/MAPK signaling pathway and consequently downregulate both EMMPRIN and MMP‑9 expression in PMA‑induced macrophages.

Modulating P2X7 Receptor Signaling during Rheumatoid Arthritis: New Therapeutic Approaches for Bisphosphonates

Bisphosphonates are metabolically stable pyrophosphate analogues that are able to mimic the anti-inflammatory function of pyroph phosphates, and are arising per se as promising anti- inflammatory drugs to treat RA.

Activation of Macrophage Promatrix Metalloproteinase-9 by Lipopolysaccharide-Associated Proteinases1

It is demonstrated here that LPS preparations are also able to activate proMMP9 made by human macrophages or THP-1 cells via LPS-associated proteinases, which cleave the N-terminal propeptide at a site or sites close to the one cleaved upon activation with organomercurial compounds.

Urokinase upregulates matrix metalloproteinase-9 expression in THP-1 monocytes via gene transcription and protein synthesis.

The results suggest that urokinase upregulates MMP9 expression in monocytes via M MP9 gene transcription and protein biosynthesis.

TNF-alpha and IL-1beta selectively induce expression of 92-kDa gelatinase by human macrophages.

Results show that expression of 92-kDa gelatinase, but not its natural inhibitor TIMP-1, by human tissue-type macrophages is selectively up-regulated by proinflammatory cytokines; which suggests that these cells, when actually present in an inflammatory environment, will actively participate in the destruction of the extracellular matrix.

The role of matrix metalloproteinase  9 in the pathogenesis of chronic lymphocytic leukaemia

The relatively specific MMP‐9 inhibitors, Ro31‐9790 (3 μmol/l) and TIMP‐1, reduced CLL‐cell migration through type IV collagen and through endothelial monolayers suggesting that the enzyme may also be important in malignant cell entry and egress to and from involved tissue.

IL-18 initiates release of matrix metalloproteinase-9 from peripheral blood mononuclear cells without affecting tissue inhibitor of matrix metalloproteinases-1: suppression by TNFα blockage and modulation by IL-10

The present study broadens the current pattern of IL-18 proinflammatory actions on PBMC, emphasizes the pivotal role of intermediate TNFα production in these responses, and relates IL- 18 biological functions to the pathological role of MMP-9.

Extracellular ATP triggers tumor necrosis factor-alpha release from rat microglia.

Results indicate that extracellular ATP triggers TNF-alpha release in rat microglia via a P2 receptor, likely to be the P2X(7) subtype, by a mechanism that is dependent on both the sustained Ca(2+) influx and ERK/p38 cascade, regulated independently of Ca( 2+) influx.

Regulation of 92-kD gelatinase release in HL-60 leukemia cells: tumor necrosis factor-alpha as an autocrine stimulus for basal- and phorbol ester-induced secretion.

It is suggested that TNF-alpha is required for basal and PKC-mediated MMP-9 release in HL-60 leukemia cells, which may potentiate the matrix degradative capacity of immature leukemic cells in the processes of bone marrow egress and the evasion of these cells into peripheral tissue.

Absence of the P2X7 Receptor Alters Leukocyte Function and Attenuates an Inflammatory Response

Data indicate that ATP does act via the P2X7R to affect leukocyte function and that it can serve as an important component of an in vivo inflammatory response.

Extracellular ATP triggers IL-1 beta release by activating the purinergic P2Z receptor of human macrophages.

The data suggest that ATPe triggers IL-1 beta via the purinergic P2Z receptor recently shown to be expressed by human macrophages and identified as a new member of the P2X family (P2X7), and provide pharmacologic tools for the modulation of IL- 1 beta release in vitro and, possibly, in vivo.
