Predicting risk of thrombosis and bleeding

This edition of the Forum is focused on applications of Systems Biology methods to  predicting risk of thrombosis and bleeding. Thrombosis, or the formation of a thrombus, relies on the interactions of blood platelets and the coagulation system with the damaged vessel wall.

To mimic these processes, a multiparameter assay has been developed in the Biochemistry department of UM, in which small volumes of blood are perfused over an array of components of the vessel wall, and where both platelet activation and coagulation can be observed in time. By using multicolour microscopy, over hundred parameters can be obtained for a given blood sample. To evaluate the interactions and relevance of these parameters, several mathematical modelling approaches are being developed and applied.

This working group brings together researchers in the Maastricht area who are interested in the development and application of “systems biology”. The main aim is to share research, experience and, through this exchange, inspire and initiate new research directions and collaborations. The meeting takes place roughly every three months in the Brains Unlimited building.

Time Subject
17:00 One hundred ways to measure a thrombosis or bleeding tendency in whole blood with clever ways of mathematical modeling ​
Johanna van Geffen (CARIM)
Johan Heemskerk (CARIM)
Rachel Cavill (DKE)

In the interactive presentation, we will first provide some clinical background on venous and arterial thrombosis (heart attack, stroke). We will sketch our current understanding about the roles of platelets and coagulation in these pathologies. We will then explain how so many parameters can be obtained using small volumes of blood.
 
The mathematical models designed to predict the contribution of the coagulation sub-pathways form the core of the presentation. Finally, we will illustrate how blood samples from genotyped patients with an increased risk of thrombosis or bleeding can be used to validate the mathematical models. The overall goal is to develop a systems biology verified multiparameter test for the prediction of increased risks of thrombosis or bleeding.
