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 WebApr 16, 2015 · Catalytically inactive tPA-S (481)A inhibited plasminogen activation by tPA and uPA, attenuated ICH, lowered plasma d-dimers, lessened thrombocytopenia, and improved neurologic outcome in WT, tPA (-/-), and uPA (-/-) mice. ICH expansion was also inhibited by tPA-S (481)A in WT mice anticoagulated with warfarin.
