Abstract

Η παρούσα εφεύρεση αναφέρεται σε ανασυνδυασμένους ιϊκούς φορείς, σε φαρμακευτικές συνθέσεις που αποτελούνται από τέτοιους ανασυνδυασμένους φορείς, και σε μεθόδους για την πρόληψη και θεραπευτική αγωγή οστεοαρθρίτιδας στα θηλαστικά. Ειδικότερα, αυτή η αποκάλυψη παρέχει φορείς αδενο-σχετιζόμενού ιού (AAV) ικανούς να εκφράζουν, σε έναν ξενιστή, οστεοπροστατευτικές/ χονδροπροστατευτικές βιοδραστικές πρωτεΐνες, που περιλαμβάνουν συνθάση 2 υαλουρονάνης 2 (HAS2) και λουμπρικίνη (PRG4). Μέθοδοι παραγωγής αυτών των AAV παρέχονται, καθώς είναι μέθοδοι αντιμετώπισης της οστεοαρθρίτιδας στις αρθρώσεις θηλαστικών, μέσω της μακροπρόθεσμης γονιδιακής έκφρασης των οστεοπροστατευτικών /χονδροπροστατευτικών πρωτεϊνών, που περιλαμβάνουν HAS2 και PRG4, τόσο σε αρθρικά κύτταρα όσο και σε χονδροκυτταρικά κύτταρα.
