[Glucose uptake of activated platelets and the influence by integrin antibodies].

Objective: To study the signal transduction in the course of energy metabolism of platelets, and to provide a new theoretical basis for clinical application of the anti-activation of platelets by the monoantibody of integrin GPIIb/IIIa.
Methods: With or without the block of integrin GPIIb/IIIa monoantibody 10E5 and/or integrin alpha v beta 3 monoantibody 609, the uptake rate of tritium-labeled 2-deoxyglucose([3H]2-DG) by platelets activated by thrombin was counted in a liquid scintillation counter. The relationship between the energy metabolism of platelets and platelet integrin was investigated by the course of glucose uptake of individual vivo platelets.
Results: Compared with unactivated platelets, the glucose uptake of activated platelets increased, and it could be blocked by monoantibody 10E5 and partly blocked by 609.
Conclusion: The glucose uptake of activated platelets can be suppressed by monoantibody 10E5, and the intergrin family is associated with the signal transduction of platelet energy metabolism. Integrin GPIIb/IIIa may play an important role in the procedure of platelet energy metabolism.
