We review select aspects of the biology of matrix metalloproteinases (MMPs) with a focus on the modulation of inflammatory responses by MMP-2. MMP-2 is a zinc- and calcium-dependent endoprotease with substrates including extracellular matrix proteins, vasoactive peptides and chemokines. Humans and mice with MMP-2 deficiency exhibit a predominantly inflammatory phenotype. Recent research shows that MMP-2 deficient mice display elevated activity of a secreted phospholipase A2 in the heart. Additionally, MMP-2 deficient mice exhibit abnormally high prostaglandin E2 levels in various organs (i.e., the heart, brain and liver), signs of inflammation and exacerbated lipopolysaccharide-induced fever. We briefly review the biology of sPLA2 enzymes to propose the existence of a heart-centric MMP-2/sPLA2 axis of systemic inflammation. Moreover, we postulate that PLA2 activation is induced by chemokines, whose ability to signal inflammation is regulated in a tissue-specific fashion by MMPs. Thus, genetic and pharmacologically induced MMP-deficiencies can be expected to perturb PLA2-mediated inflammatory mechanisms.

Local sinonasal inflammation resulting from altered T-cell immune signaling is a contributor to the pathogenesis of chronic rhinosinusitis (CRS). CRS patients experience negative impacts on quality of...
Systemic inflammation is potentially associated with ocular diseases such as late age-related macular degeneration (AMD). Using the serum concentration of high-sensitive C-reactive protein (hs-CRP) as...
Our article is focused on emerging pathogenetic pathways in systemic lupus erythematosus (SLE). Notably, IL-12 and IL-23 have been described as emerging cytokines in SLE pathogenesis. We know that IL-...
Introduction: Long-term systemic inflammation may cause type 2 diabetes. Medications used to treat type 2 diabetes don't target inflammation therefore it's necessary to study how hypoglycemics can imp...
Chronic inflammation may lead to cochlear damage, and the only longitudinal study that examined biomarkers of systemic inflammation and risk of hearing loss found an association with a single biomarke...
Lipoprotein-associated phospholipase A2 (LP-PLA2) is a good marker of cardiovascular risk and inflammation. This study aims at the characteristic and clinical significance of LP-PLA2 test ...
The purpose of this study is to better understand (1) if phospholipase A2 producing microorganisms and cytokines (IL-1, IL-4, IL-6, IL-10, and IL-13) are associated with premature labor (2...

The purpose of this study is to examine the role of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) in triglyceride metabolism.
A secreted matrix metalloproteinase which is highly expressed by MACROPHAGES where it may play a role in INFLAMMATION and WOUND HEALING.
A phosphoinositide phospholipase C subtype that is primarily regulated by its association with HETEROTRIMERIC G-PROTEINS. It is structurally related to PHOSPHOLIPASE C DELTA with the addition of C-terminal extension of 400 residues.
A transmembrane domain-containing matrix metalloproteinase. It is synthesized as an inactive zymogen that is activated by the action of PROPROTEIN CONVERTASES such as FURIN. Matrix metalloproteinase 14 plays a direct role in the cleavage of proteins in the pericellular environment. In addition it can function indirectly by enzymatically activating the proprotein form of MATRIX METALLOPROTEINASE 15.
A transmembrane domain-containing matrix metalloproteinase. It is synthesized as an inactive zymogen that is activated by the proteolytic action of PROPROTEIN CONVERTASES. Matrix metalloproteinase 16 plays a direct role in the cleavage of proteins in the pericellular environment. In addition it can function indirectly by enzymatically activating the proprotein form of other MATRIX METALLOPROTEINASES such as the zymogen of MATRIX METALLOPROTEINASE 2.
