Inactive tpa
Webcally inactive tPA into these mice before KA injection restores microglial activation (Rogove et al., 1999). These data indicate that contrary to its proteolytic role in neurotoxicity, tPA activates microglia via a nonproteolytic mechanism. In addition to its catalytic domain, tPA also contains a fibronectin type-3 finger WebFeb 20, 2024 · Tissue plasminogen activator (tPA) is a serine protease involved in fibrinolysis. It is released by endothelial cells, but also expressed by neurons and glial cells in the central nervous system (CNS). Interestingly, this enzyme also contributes to pathological processes in the CNS such as neuroinflammation by activating microglia and increasing …
