Tissue plasminogen activator (tPA) plays a role in the mammalian nervous system. Research using genetic models and various experimental systems evaluates tPA

Area of Science:

Neuroscience
Biochemistry
Molecular Biology

Background:

The extracellular protease tissue plasminogen activator (tPA) is involved in numerous physiological and pathological processes within the mammalian nervous system.
Understanding the precise functions of tPA is crucial for neurological research.

Purpose of the Study:

To summarize the current understanding of the roles of the tPA/plasminogen system in neuronal function and dysfunction.
To highlight the impact of advanced research models on evaluating these roles.

Main Methods:

Utilizing transgenic and knock-out mouse models with varied tPA expression levels.
Employing in vivo models for functional and disease studies.
Conducting in vitro culture models to examine cellular behavior.
