Abstract

Adenovirusni vektori imaju potencijalno translacijsku i komercijalnu vrijednost, a trenutno se istražuju kao vektori za prijenos nukleinskih kiselina i vakcinaciju. Adenovirusni vektor najčešće korišten u kliničkim istraživanjima je adenovirus tip 5 (AdV5) koji je do sada ujedino i najbolje istražen adenovirus. Prema literaturnim podacima, poznato je da je klatrin uključen u endocitozu AdV5 te smo u ovom radu smanjenjem ekspresije klatrina željeli ispitati da li istu ili sličnu ulogu klatrin ima i u uspješnosti transdukcije adenovirusa tip 26 (AdV26) i adenovirusa tip 35 (AdV35), dva niskoseroprevalentna adenovirusa koji su se pokazali kao obećavajući kandidat za razvoj novih vektorskih vakcina. Klatrin je utišan u A549 stanicama te je nakon određivanja uspješnosti transdukcije adenovirusa, pokazano da smanjenjem količine klatrina dolazi do smanjenja uspješnosti transdukcije s AdV5 i povećanja uspješnosti transdukcije s AdV26. Smanjenje ekspresije klatrina nije imalo značajniji utjecaj na uspješnost transdukcije s AdV35. Rezultati dobiveni u ovom istraživanju ukazuju na važnost klatrinom posredovane endocitoze u uspješnosti transdukcije AdV26 što do sada nije bilo poznato iz literature.

Abstract (english)

Adenovirus based vectors have potential translational and commercial values and are currently studied as vectors for DNA transfer and vaccination. The adenovirus vector most commonly used in clinical trials is adenovirus type 5 (AdV5) which is by far the best researched adenovirus. According to the literature, it is known that clathrin is involved in AdV5 endocytosis, and in this study, we wanted to examine whether clathrin plays the same or similar role in the success of adenovirus type 26 (AdV26) and adenovirus type 35 (AdV35) transduction efficiency, two low seroprevalent adenoviruses which proved to be very promising as a vector vaccine. Clathrin was silenced in A549 cells and after determining the success of adenovirus transduction, it was shown that decreasing the amount of clathrin leads to a decreased transduction efficiency with AdV5 and increased transduction efficiency with AdV26. Decreased clathrin expression did not have a significant effect on the transduction efficiency with AdV35. The results obtained in this study indicate the importance of clathrin-mediated endocytosis in the success of AdV26 transduction, which has not been known from the literature so far.
