Tissue-type plasminogen activator is a neuroprotectant in the mouse hippocampus.

The best-known function of the serine protease tissue-type plasminogen activator (tPA) is as a thrombolytic enzyme. However, it is also found in structures of the brain that are highly vulnerable to hypoxia-induced cell death, where its association with neuronal survival is poorly understood. Here, we have demonstrated that hippocampal areas of the mouse brain lacking tPA activity are more vuln...

Tissue-type plasminogen activator is a neuroprotectant in the central nervous system

Tissue-type plasminogen activator (tPA) is a serine proteinase found not only in the intravascular space but also in a well-defined sub-set of neurons in the brain. tPA is rapidly released from neurons after either exposure to hypoxia or hypoglycemia in vitro, or the induction of cerebral ischemia in vivo. It has been proposed that tPA has a neurotoxic effect in the ischemic brain. However, rec...

Human tissue-type plasminogen activator.

Tissue-type plasminogen activator (t-PA ) plays an important role in the removal of intravascular fibrin deposits and has several physiological roles and pathological activities in the brain. Its production by many other cell types suggests that t-PA has additional functions outside the vascular and central nervous system. Activity of t-PA is regulated at the level of its gene transcription, it...

Mouse ovarian granulosa cells produce urokinase-type plasminogen activator, whereas the corresponding rat cells produce tissue-type plasminogen activator

It is well established that rat ovarian granulosa cells produce tissue plasminogen activator (tPA). The synthesis and secretion of the enzyme are induced by gonadotropins, and correlate well with the time of follicular rupture in vivo. We have found that in contrast, mouse granulosa cells produce a different form of plasminogen activator, the urokinase-type (uPA). As with tPA synthesis in the r...

Single-chain tissue-type plasminogen activator is a substrate of mouse glandular kallikrein 24.

Leydig cells of the adult mouse testis express at a detectable level three distinct glandular (tissue) kallikrein genes: mKlk21, mKlk24, and mKlk27. Recently, the proteins encoded by these genes were characterized using active recombinant proteases, but their roles in the mouse testis remained to be determined. The present study showed that among the proteases, mK24 markedly enhanced the activi...
