• Synonyms:Matrix metalloproteinase-9, Gelatinase B
  • Biomarker name:MMP9
  • Gene name:MMP9
  • Gene id:4318
  • Genecards link:
  • Biomarker function:Role in local proteolysis of the extracellular matrix and in leukocyte migration. Cleaves type IV and type V collagen. Degrades fibronectin but not laminin.
  • Neurovascular unit:Extracellular matrix
  • Intracellular location:Secreted
  • Body fluids:Plasma, Serum, CSF
  • Prot-prot interactions:Yes:
  • Inductors:Unknown
  • Inhibitors:Yes:
  • Signaling pathway:Unknown
  • Biological process:Collagen degradation
  • Comments:Its proteolytic action over the extracellular matrix is related with angiogenesis processes.
  • Associations:Associated with BBB disruption. Positively correlated with stroke severity and infart volume within acute phase of ischemic stroke. Raised plasma MMP-9 in stroke patients than mimics. Its relationship with poor outcome is not clear. Similar levels have been determined in both subtypes of stroke during acute phase.
