Résumé : Dipyridamole is a potent inhibitor of tritiated thymidine incorporation by PHA-stimulated human lymphocytes. This effect is unrelated to the length of culture, to the level of response in untreated cultures, or to the proliferative index. This suggests that dipyridamole principally effects the membrane transport of thymidine. Dipyridamole inhibits sheep-erythrocyte-capping by E-rosettes. This effect cannot be mimicked by theophylline or cyclic nucleotides and cannot be reverted by adenosine. Pharmacological studies with colchicine and cytochalasin B suggest interference with cytoskeletal functions, probably of microtubules. This could be another site of action of dipyridamole beyond phosphodiesterase inhibition and adenosine metabolism.
