Feb 20, 2021·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 blood–brain barrier permeability.

Tissue Plasminogen Activator (tPA) - Diapharma

Tissue plasminogen activator (tPA, tissue-type plasminogen activator) is a serine protease found on endothelial cells (cells that line the blood vessels) involved in the breakdown of blood clots (fibrinolysis). tPA enzyme catalyzes the conversion of plasminogen to plasmin. tPA can used in embolic or thrombotic stroke research. tPA may be manufactured using recombinant biotechnology techniques ...
