Hepatitis B virus (HBV) infection can result in progressive inflammatory liver diseases that are associated with the development of hepatocellular carcinoma. Our understanding of the HBV infection proteome is limited, and we used label-free quantitative (LFQ) proteomics to address this gap in knowledge. Kinetic sampling of mock and HBV infected human hepatoma HepG2 cells showed a time-dependent expression of the viral core (C) and Surface (S) proteins. Concomitantly, we observed altered host cell proteome dynamics, including cytoskeletal proteins, collagens, fibrinogen subunits, extracellular matrix receptor interaction and focal adhesion pathways, as well as an elevated abundance of complement proteins. Specifically, we noted evidence for elevated C5 complement protein abundance in the HBV infected cells, highlighting selective complement adaptations during infection.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
