MMPs rearrange DNA

Single Bursts of Individual Granule Cells Functionally Rearrange Feedforward Inhibition

The sparse single-spike activity of dentate gyrus granule cells (DG GCs) is punctuated by occasional brief bursts of 3-7 action potentials. It is well-known that such presynaptic bursts in individual mossy fibers (MFs; axons of granule cells) are often able to discharge postsynaptic CA3 pyramidal cells due to powerful short-term facilitation. However, what happens in the CA3 network after the p...

Substrate Specificity of MMPs

MMPs and ADAMTSs: functional studies.

Members of the MMP (matrix metalloproteinase) and ADAMTS (a disintegrin and metalloproteinase with thrombospondin type I motifs) families of enzymes are capable of cleaving a diverse array of cellular, extracellular and extracellular matrix substrates, including collagens and procollagens, proteoglycans, cytokines and cytokine ligands, chemokines, elastin and von Willebrand factor, thereby modu...

2 Substrate Specificity of MMPs

TIMPs, MMPs and cardiovascular disease.

The matrix metalloproteinases (MMPs) are a family of proteolytic enzymes that cleave the extracellular matrix and have been shown to be regulated by a class of proteins called the tissue inhibitors of metalloproteinases (TIMPs). Several studies have shown that extracellular matrix degradation by MMPs, specifically MMP-9, is involved in the pathogenesis of a wide spectrum of cardiovascular disor...
