NP plays a central role in viral replication [18]. As a structural protein with no intrinsic enzymatic activity [19], it is the most abundant viral protein in infected cells.

In an influenza infection, nucleoprotein is the first viral protein to replicate, so the infected cell quickly presents the nucleoprotein antigens, provoking a strong early immune response, they explained.

"Another aspect worth pointing out is that protection against currently circulating influenza viruses has been reached even with a very old variant of the nucleoprotein protein," they continued.

"The OVX836 vaccine is based on the full-length nucleoprotein of the influenza A virus A/WSN/1933 (H1N1), and, despite the fact that this antigen is highly conserved and has been through over 90 years of evolution, this protein has undergone some changes...

Of the 11 RSV-encoded proteins, N is one of the most conserved structural proteins and is essential for virus encapsidation by coating the entire viral RNA genome to form the ribonucleoprotein (RNP).

These data suggest that the antigenic repertoire of T cells in IS subjects is skewed compared to HSV-2+ subjects and that IS subjects had more frequent T cells responses to IE proteins and infrequent T cell responses to virion components.

The preponderance of T cell responses directed at IE proteins in IS subjects suggests that IS subjects have been exposed to replicating virus since IE proteins are the first proteins made during the virus infectious life cycle and are not present in infectious virions. T cells directed at IE proteins would be engaged early in the infectious life cycle and may be able to kill the virally-infected cell before the production of infectious progeny and thus advantageous to the host. If some of the IS subjects are infected with HSV-2 in the absence of seroconversion, the presence of T cells directed at IE proteins at the neural-epidermal junction would provide the quickest defense against the virus spreading to the periphery and may explain why we did not detect any HSV DNA at mucosal sites in IS subjects (4).

The HPV genome contains an early expressed region containing the ORF (Open reading frames) of E1 to E7 genes which are necessary for viral replication and transcriptional regulation6. The E6, E7 and E5 proteins are able to interact with many cell targets, promoting cellular transformation7,8. The E1 protein is encoded within the early expressed region and it is localized in nuclear and cytoplasmic fractions. This protein is highly conserved among different HPV types and is the unique HPV protein with enzymatic activity.

The initiation of the HPV infection is from the basal layer of the squamous epithelium. The viral replication process and transcription of other E proteins are regulated by E1 and E2 proteins...

E1 protein has been reported highly conserved among the types of HPV and commonly decoded during the early expression of HPV infection...

E1 and E2 proteins play crucial role in the initiation and regulation of HPV replication as illustrated in Fig. 1. Initially, E2 proteins bind to their binding sites (E2BS11 and E2BS12) at the origin of replication, which recruits a pair of E1 proteins to form a complex.

The European Commission, as part of its efforts to create a -Digital Single Market" and further to build more competitive and innovative Capital Market Union, announced its FinTech Action Plan on March 8, 2018.1

The Action Plan sets out 23 steps to accomplish the following main objectives: enabling innovative business models to reach a European scale (based on a consistent licensing regime), supporting innovations and implementation of new technologies in the financial sector, and increasing its integrity and security.

Among the initiatives are:

A proposal for an EU Regulation on investment-based and lending-based crowdfunding service providers (ECSP) for business. The regulation aims to set an appropriate and proportionate framework enabling crowdfunding platforms to operate cross-border under a comprehensive passporting regime and unified supervision;2

An EU Public Blockchain initiative of the European Commission to develop a comprehensive strategy for implementation of distributed ledger technologies in all sectors of the economy, considering the associated legal implications;

A public consultation on further digitalization of regulated information about companies listed on EU regulated markets, considering a possible establishment of a European Financial Transparency Gateway based on distributed ledger technology; and

Hosting an EU FinTech Laboratory, which will serve as a platform for neutral exchange among European and national authorities with technology providers.

As part of the Action Plan, in February 2018, the European Commission launched an EU Blockchain Observatory and Forum, as well as a feasibility study of an EU public blockchain infrastructure to develop cross-border services. As part of its efforts to evaluate legal, governance issues, any scale-up opportunities and in attempt to support -interoperability and standardization" across Europe, the European Commission will continue the work on further possible implementations of distributed ledger technologies in the second quarter of 2018. It will utilise cooperation with standard-setting bodies, as well as other international authorities and organisations to attain its objectives.

Digital assets and initial coin offerings (ICOs) also attracted the focus of the European Commission. Together with the European Supervisory Agencies, the European Central Bank and the FSB, the European Commission will continue monitoring the developments in this subject area. Considering the risks associated with the digital assets transactions and the appropriateness of the regulatory framework, the European Commission will assess, by the fourth quarter of 2018, at what extend a regulatory action on an EU level is necessary.

In this context, last month the European Supervisory Agencies - EBA, ESMA and EIOPA - issued a coordinated warning to the consumers about the high risk of investment in virtual currencies associated with uncertainty in the regulation and their extreme volatility.3 This notification followed the alerts issued in November 2017 by ESMA to investors concerning the high risk of investing in ICOs and on the rules applicable to firms involved in ICOs.4

Additional aspects to consider when analysing digital assets include the impact of the General Data Protection Regulation (GDPR) entering into force in May 2018,5 the eIDAS Regulation6 and the recent proposal to extend the scope of the Anti-Money Laundering Directive to virtual currency exchanges and wallet providers.7

Finally, a further step forward in the regulation of digital assets and ICOs was taken outside the EU with the publication of the ICO Guidelines by FINMA (the Swiss Financial Market Supervisory Authority) on February 16, 2018. The document complements the FINMA Guidance 04/2017 and provides further information and clarification on how the authority aims to employ the financial markets legislation by dealing with ICO organisers.8
