Understanding antigenic diversity, zoonotic potential and immunological prevention of avian influenza viruses affecting poultry

Lead Research Organisation: The Pirbright Institute
Department Name: Avian Influenza

Abstract

Increasing poultry production is crucial for maintaining food supplies to feed the ever-increasing human population, and to meet the Sustainable Development Goal on food security and sustainable agriculture. However, emergence, re-emergence, and continued prevalence of avian influenza viruses (AIVs) in recent years threaten the sustainable growth of the poultry sector. Control of AIVs in areas of hyper-endemicity is primarily achieved through vaccination. However, effectiveness of most conventional poultry vaccines is intrinsically sub-optimal; these vaccines generally only mask clinical signs and mortality, while still allowing infected animals to shed infectious viruses. Existing vaccines may consequently result in continued circulation and evolution of AIVs, and improved vaccines are therefore required that produce robust, sterile immunity against clinical disease and silent transmission, thus breaking the endemic cycle within farming systems.

The proposed research aims to gain insight into viral factors that contribute to vaccine failure which may enhance the ability of AIVs to cross species barriers from birds to mammals. We will utilise next-generation vaccination technologies and develop robust and effective vaccines that elicit strong and durable humoral and cellular immune responses against AIVs that cause severe economic losses in poultry. Our specific objectives are to investigate: (i) what changes in contemporary AIV of H5 and H7 subtypes infecting poultry can be implicated in vaccine failure, or are critical for inducing protective immunity in vaccinated birds; (ii) how do molecular changes in the virus surface increase the ability of the virus to transmit from poultry to humans; (iii) the delivery of protective antigens to chicken immune cells to potentiate more robust protection against AIV.

Achieving these objectives will provide unique data sets enabling: (i) selection of vaccine strains that match with the field viruses to provide greater protection in vaccinated birds; (ii) assessment of the likelihood of increased zoonotic infection risks to humans from the currently circulating AIV viruses in China; (iii) development of novel vaccine technologies that utilises attenuated live viruses as vaccine delivery vectors, such as recombinant herpesvirus of turkey (HVT). The efficient production and controlled delivery of protective AIV antigens to immune cells will drive induction of rapid, strong and life-long humoral and cellular immunity in chickens.

The ready availability of better disease control tools will aid in the reduction of poultry production losses and thus be important for global food security and improved animal welfare, whilst also reducing possible zoonotic transmission to humans. Thus, the proposed research partnership will provide direct benefits to farming communities and substantial indirect economic, public health, environmental and social benefits on a global scale.

Planned Impact

The proposed research will develop new knowledge and tools for combating H5 and H7 avian influenza virus (AIV) infections in poultry, thus minimising their zoonotic transmission to humans. The negative consequences of animal pathogens on trade restrictions, food security, public health, and the livelihood and quality of life of millions of farming and farming-associated communities around the world is evident globally. This is exemplified from the recent outbreak of H5N8 and H7N7 high pathogenicity avian influenza in the UK in 2015/2016, in which only a handful of localised farm outbreaks led to the culling of over one million high-value units of poultry. Furthermore, a 10-kilometre restriction zone was implemented around the infected premises where domestic poultry and mammals were not allowed to be moved, resulting in further economic losses to neighbouring farms. Considering these scenarios, any further spread of AIV could incur severe losses to the UK poultry industry, which accounts for approximately £8 billion in the UK economy and supports over 80,000 jobs. An even higher level of devastation to poultry production is being caused by both H5 and H7 viruses in China, as well as many other countries around the world. Additionally, zoonotic infections in humans have resulted in over 450 deaths from H5N1 globally since 2003, and over 600 deaths from H7N9 mainly in China since 2013. Minimising the impact of these viruses in poultry, with the concomitant reduction in zoonotic transmission, requires the improved knowledge of their genetic and antigenic diversity that this project will provide, enabling development of more effective control measures including new and improved vaccination technologies. Such steps will particularly help reduce the prevalence of AIVs in China, where the disease is endemic in poultry.

Our proposed research will provide integrated and innovative approaches to the prevention and control of AIV by demonstrating antigenic and receptor-binding properties of contemporary field viruses which inflict economic losses in poultry and cause zoonotic infections in humans. The specific outcome of this research will allow vaccine seed strain selection that induces cross-protective immunity against emergent field variants. Novel vaccine technologies that deliver protective antigens directly to immune cells through attenuated live virus vectored vaccines will induce strong cellular and humoral immunity. This immunity should overcome the sub-optimal performance and other inherent drawbacks of currently available conventional killed virus vaccines. This research will therefore be of value to many stakeholders involved in animal and public health and in food security.

The research impacts will be enhanced by prompt publishing of the outcomes via peer-reviewed, open-access journals, as well as regular presentations at conferences and workshops. Proactive engagements will be undertaken with potential stakeholders with interest in improving livestock disease control and prevention strategies, including funding bodies and policy makers in UK (BBSRC, MRC, Defra), China (NSFC), partner institutions, and international organizations (World Organization for Animal Health (OIE), Food and Agriculture Organization of the United Nations (FAO), World Health Organization (WHO). To achieve these goals all PIs, researchers and collaborators involved in the project will use every available opportunity to disseminate the research to relevant stakeholders for the wider public benefit.

Description The research developed in vitro-based virus-immune escape assays that imitate natural virus evolution within vaccinated animals. This in vitro antiserum escape mutant selection method proved very powerful tool to predict the antigenic change of influenza viruses, also replacing the animal use for these studies

We employed a combination of techniques to provide an enhanced understanding of the molecular determinants in the haemagglutinin (HA) proteins of H5, H7 and H9 viruses that drive antigenic variability and vaccine failure. The results provide new molecular markers of antigenic change for AIVs that will help explain vaccine breakdown in the field. We also observed changes to epitope structure that determine antigenicity

Vaccination of poultry is a key element for the disease control in endemic countries, but vaccine effectiveness is persistently challenged by the emergence of antigenic variants. We used a combination of emerging molecular virology, immunology and vaccinology techniques to provide an enhanced understanding of the molecular determinants in the haemagglutinin (HA) proteins of H9 viruses that drive antigenic variability and vaccine failure. We identified amino acid substitutions essential for the ability of mutant viruses to escape immune pressure and alter antigenicity compared with the wild type H9N2 viruses.

Description The research defined underlying mechanism how natural infection and vaccine induced immunity drive avian influenza H7N9 avian infleunza viruses to evolve and persists in poultry. The research outcomes will help for selection of future vaccine development and seed strain assessment by providing quantitative molecular markers that can help explain vaccine breakdown in the field and predict levels of antigenic drift during virus surveillance. We find evidence for the importance of other mechanisms of immune escape, with substitutions increasing glycosylation or receptor-binding avidity exhibiting the largest impacts on chicken antisera binding. Of these, meta-analysis indicates avidity regulation to be more relevant to the evolution of circulating viruses, suggesting that a specific focus on avidity regulation is required to fully understand the molecular basis of influenza virus antigenicity, immune escape and vaccine failure. These results will guide surveillance efforts against arising antigenic variants as well as evidence-based vaccine seed selection and vaccine design.

PI Contribution The overarching aims of the proposed research are to improve controls against H5 subtype of avian influenza viruses infecting poultry by investigating underlying mechanisms that define how vaccines renders effectiveness and develop novel approaches enhancing the effectiveness of H5 avian influenza vaccines. We recently generated a panel of monoclonal antibodies (mAbs) that recognise a variety of different clades of H5 viruses. Propagation of AIV in eggs or cultured cells together with mAbs drives virus to escape from mAbs neutralisation activity. These classical virus neutralization assays (VN) followed by HA gene sequence analysis allowed us to defined the role of amino acid substitutions that are associated with evasion of antibody neutralization through emergence of antigenic variants and failure of vaccine efficacy.
Collaborator Contribution provided intellectual input for achieving prescribed objectives of this work.
Impact Talk entitled "Molecular determinants for antigenicity and vaccine efficacy of avian influenza viruses" was presented at Newton Agham Researcher Links Workshop " Novel Vaccines and Diagnostic Technologies against Emerging and re-emerging Veterinary Pathogens" at Rizal Park Hotel, Manila, Philippines, 4-7 February 2019.

PI Contribution The focus of the research is to achieve sustainable global intensification of poultry meat and egg production whilst reducing risks to human and animal health and welfare. We are undertaking research to investigate the diversity of avian influenza viruses prevalent in poultry and wild birds in south east Asia.
Collaborator Contribution Royal Veterinary College, London is leading this GCRF One Health Poultry Hub. The project will address the need to meet rising demand for poultry meat and eggs in developing countries, while minimising risk to international public health. Population growth is driving global demand for poultry, meat and egg production; this unfortunately creates conditions in which animal diseases can spread to humans ('zoonoses'). These include bacterial food poisoning and strains with avian influenza with epidemic or pandemic potential. The GCRF One Health Poultry Hub will adopt a 'One Health' approach to the issue of combatting animal-to-human diseases by bringing together a team of laboratory, clinical, veterinary and social scientists. This team will test and evaluate novel interventions. The need for safe poultry production is most urgent in South and South East Asia, so the RVC and its partners will then use their local networks in these regions to put its positive research to immediate use.
Impact Development of international interdisciplinary partnership of 55 investigators from 13 countries to address the emerging global challenges of food security and public health associated with intensification of poultry production.
