Rouleau formation of erythrocytes is influenced by thrombocytes.
Thrombocytes are activated by shearing and influence possibly the flow properties of blood. Erythrocytes resuspended in platelet poor plasma show a significantly increased deformability as well as reduced aggregability after addition of ADP as well as adrenaline in comparison with control. In platelet rich plasma the aggregation of erythrocytes becomes enhanced. This is discussed in respect of a release of macromolecules of platelets.
