Platelet dysfunctions are shared by cardiovascular diseases and a wide range of inflammatory diseases.
Aims
To determine the ability of a new whole tomato-based food supplement (WTBFS) containing carotenoid and olive polyphenols to inhibit platelet aggregation.
Methods
Aggregation was evaluated in platelet-rich plasma using microtiter plates and a plate reader.
Results
Platelets treated with WTBFS showed a >70% reduction of 5 µM adenosine diphosphate (ADP)-induced platelet aggregation; at 10 µM of ADP, the inhibitory effect of WTBFS was reduced of about 50%. Similarly, 78% and 48% reduction were obtained using 5 µg/mL and 10 µg /mL of collagen as an agonist
Conclusion
Since the compounds in WTBFS share the ability to inhibit STAT3, the inhibition of its signaling pathway may represent the mechanism underlying the antiplatelet activities. The activity of a lipophilic solution prepared from WTBS was in vitro tested on the platelet aggregation in response to ADP agonists and Collagen.
