these differences in the changes in polyphosphoinositide metabolism in adp- and thrombin-stimulated platelets are consistent with the hypothesis that the decrease in pip2 in adp-stimulated platelets may be due not to degradation of pip2 by phospholipase c , but rather to a shift in the equilibrium between pip2 and phosphatidylinositol 4-phosphate ( pip ) .
