Thrombin stimulation of human blood platelets caused an extensive (up to 45 %) and rapid (5–10 s) decline in endogenous phosphatidylinositol 4,5-bisphosphate (PI-P2). Thrombin initiated an equally rapid loss of membrane-bound Ca, as indicated by the decrease in fluorescence of chlortetracycline (CTC)-loaded platelets. PI-P2breakdown also correlated with decreased CTC fluorescence upon use of other platelet stimuli: Arachidonate caused moderate and slow decreases in both PI-P2and CTC fluorescence, while ionophore only induced minimal changes. Thrombin-induced decreases in PI-P2content could account for release of sufficient membrane-bound Ca to raise cytoplasmic free [Ca2+] to 1–2 uM, supporting the hypothesis that PI-P2represents the Ca-binding site involved in the stimulus-dependent increase in cytoplasmic Ca2+evoked by receptor-ligand interactions.
