Thrombin-induced polymers

The inducers of these alterations range from certain proteolytic enzymes, in particular thrombin, to large molecules such as collagen, immune complexes, zymosan (alpha 41) and cationic polymers (alpha 28), and, finally, low molecular weight compounds such as adenosine-5-diphosphate (ADP), adrenaline, vasopressin, and serotonin. This wide variety of materials, all of them capable of eliciting the same result, suggests that.upon quite different stimuli of the plasma membrane, the same sequence of events is triggered off. These events can be subdivided by several criteria in different phases ...
