Fibrinolysis Flashcards
1
Q
tPA dependent plasmin generation
A
tPA produced by endothelial cells + cofactor Ia > Plasminogen to plasmin
2
Q
uPA dependent plasmin generation
A
Produced by endothelial & epithelial cells, macrophages
sc-UPA + plasmin > tc-UPA > plasminogen to plasmin
3
Q
Plasmin
A
Cleaves between the E- and D-domans of fibrin
4
Q
PAI-1
A
Produced by endothelium, platelets, monocytes
tPA & uPA inhibitor
5
Q
Alpha2AP
A
Produced by liver
Fast and efficient inhibition of plasmin
6
Q
TAFI
A
TAFI + IIa > TAFIa
Removes lysins from fibrinsurface > tPA and plasminogen cannot bind
