Matrix metalloproteinases in brain development and remodeling: Synaptic functions and targets

Ethell, Iryna M., Ethell, Douglas W.·2007·Journal of Neuroscience Research

Abstract

Matrix metalloproteinases (MMPs) play critical roles in egg fertilization, embryonic development, wound repair, cancer, and inflammatory and neurologic diseases. This subfamily of metzincin peptidases can cleave extracellular matrix (ECM) and pericellular proteins that have profound effects on cell behavior. Among known MMP substrates are several proteins that play important roles in synaptogenesis, synaptic plasticity, and long‐term potentiation (LTP). In this Mini‐Review we discuss how MMP‐directed cleavage of these proteins can impact the formation and function of synapses within the brain. Pyramidal neurons in the hippocampus, and other large neurons, are surrounded by perineuronal nets that are composed of brevican, tenascin‐R, and laminin, each of which is subject to proteolytic cleavage by MMPs. Tenascin‐R knockout mice show deficits in learning and memory and LTP, as do at least two MMP knockouts. Impaired LTP is also seen in brain‐derived neurotrophic factor (BDNF) knockout mice, which is interesting in that pro‐BDNF can be processed into mature BDNF by several MMPs and thereby regulate activation of the high‐affinity BDNF receptor TrkB. At the synaptic level, MMP substrates also include ephrins, Eph receptors, and cadherins, which are also involved in synapse development and plasticity. MMPs can also process membrane‐bound tumor necrosis factor‐α into a potent soluble cytokine that is increasingly implicated in neuron–glial signaling, particularly in neurologic disease. Finally, we discuss how the development of therapeutics to attenuate MMP activity in neurodegenerative disorders may become powerful tools for future studies of synaptic formation and function within the developing and mature brain. © 2007 Wiley‐Liss, Inc.

  • The ECM can be modified rapidly by the release of proteases, by microglial action and by internalization, all of which can be activated by memory events.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
