BACKGROUND Experimentally, metalloproteinases (MMPs) play a detrimental role related to the severity of ischemic brain lesions. Both MMPs activity and function in tissues reflect the balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs). We aimed to evaluate the role of MMPs/TIMPs balance in the setting of rtPA-treated stroke patients. METHODS Blood was taken before and 24-...
BACKGROUND Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI. Here we repo...
Chronic inflammation and oxidative stress (OS) are present in Alzheimer's disease (AD) brains in addition to neuronal loss, Amyloid-β (Aβ) plaques and hyperphosphorylated tau-protein neurofibrillary tangles (NFTs). Previously we showed that levels of the pro-inflammatory cytokine, interleukin-18 (IL-18), are elevated in post-mortem AD brains. IL-18 can modulate the tau kinases, Cdk5 and GSK3β, ...
The role of membrane-type (MT) 2-matrix metalloproteinase (MMP) in the cellular activation of MMP-2 and the tissue inhibitor of matrix metalloproteinase (TIMP) requirements for this process have not been clearly established. To address these issues a TIMP-2-free cell line derived from a Timp2-/- mouse was transfected for stable cell surface expression of hMT2-MMP. Untransfected cells did not ac...
The tissue inhibitors of metalloproteinases 1–4 (TIMPs) have discrete regulatory roles in the activation of matrix metalloproteinase (MMP)-2 (gelatinase A), an important basement membrane-degrading MMP pivotal to tumor metastasis and angiogenesis. TIMP-2 binds to both the hemopexin C domain of progelatinase A and the active site of membrane type-1 (MT1) MMP. This trimeric complex presents the c...
