Sequências de Ribonucleotídeos Quimicamente Modificadas como Moduladores da Atividade de Receptores Purinérgicos P2Y2 e Aptâmero B7



Purinergic receptors, activated by extracellular ATP, are present in all tissue types and participate in physiological and pathophysiological processes. The  P2Y2 receptor subtype is involved in numerous pathologies including Alzheimer´s diease, epilepsy, lung injury emphysema, cystic fibrosis and several types of cancer.  A prominent  function of this receptor is promotion of survival of tumor cells. In view of the lack of specific inhibitors for the P2Y2 receptor, the SELEX technique was used for developing high-affinity receptor blockers.



-Use the aptamer technology for developing high-affinity and specificity synthetic inhibitors for P2Y2 receptors.

- Use aptamers for P2Y2 receptor identification in tumor cells using cytometry techniques.

- Evaluate the potencial of anti-P2Y2 aptamers in blocking cancer cell proliferation and invasiveness.

- Study of aptamer effectiveness in blocking metastasis in preclininical mouse models transplanted with tumors.

- Safety tests and use anti-P2Y2 aptamers  for tumor  therapy in clinical trial
