For instance, if we examine an individual that basically develops an embolism in the coronary artery. So essentially, if we give an individual that is experiencing a heart attack the tissue tie plasmidgen activator, if we inject it into the blood of that individual, what happens is this tissue type plasmidogen activator initiates these plasmid molecules. So activates transforms the plasmidogen into plasma. And what plasma does is plasma moves into that coronary artery of the heart of that individual experiencing the heart attack and it basically begins to break down the blood clot that is formed as a result of that embolism. And so by giving an individual who is experiencing a heart attack the tissue type plasmidogen activator, that greatly increases the likelihood that an individual will actually survive that heart attack. So we can see that these different molecules can be used for medicinal purposes in many different ways.
