Abstract

PPV4 transcribes its genome from a single promoter, and the RNAs are generated via alternate splicing coupled with alternate polyadenylation, a strategy similar to that of the bocaviruses; however, several differences were detected. The PPV4 ORF1 codes for four NS proteins, while the bocavirus ORF1 codes for 1-3 NS proteins. Whereas the VP1/VP2 capsid proteins of bocavirus are encoded by a single RNA, VP1 and VP2 of PPV4 are encoded by two separate RNAs. While ORF3 of PPV4 encodes two NP proteins, ORF3 of bocavirus codes for only one NP polypeptide. Taken together, PPV4 is unique among the parvoviruses.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
