C2238/αANP induces platelet activation. (A,B) Platelets were incubated without the peptide or with either T2238/αANP or C2238/αANP at the specified concentration (10−6 M or 10−10 M) and the platelet activation was triggered by a sub-threshold concentration of collagen (0.3 µg/ml). Platelet aggregation (A) and the concentration of the soluble CD40 ligand released by platelets (B) were assessed. N = 12. The results were expressed as mean ± SEM. In all the groups, a similar volume of solvent was added.
