Summary
Influenza viruses have the ability to pre-dispose infected hosts toward secondary bacterial complications. The mortality of viral infections that are complicated by a concurrent, or subsequent, bacterial infection (known as a super-infection), is often greater than that of either the virus or the bacteria alone. We will develop a novel multi-pathogen vaccine candidate against the major upper respiratory tract pathogens - Influenza A and Streptococcus pyogenes to prevent super-infections.
Harnessing Tyrosine Metabolism To Combat Respiratory Diseases

Summary
Cross-talk between our immune system and the microbiome is central to health and disease. In particular, the gut microbiome has wide-ranging effects throughout the body, in part through the production of metabolites with immunomodulatory activity. We have discovered a novel subset of microbial metabolites which can protect mice against allergic airway inflammation, a model of asthma. We now aim to discovery how these metabolites work with a view towards developing them as therapeutics.
HARNESSING T CELL QUALITY FOR PANDEMIC PREPAREDNESS

Summary
Developing highly effective vaccines is critical to rapidly combat global pandemics. To generate a protective antibody response against novel viruses, a vaccine must elicit a targeted B cell response supported by effective CD4 T cell help. We propose that existing CD4 T cell memory can be harnessed to rapidly and effectively support B cell responses to novel vaccine candidates. This work will contribute to pandemic preparedness strategies and improve the development pathway for new vaccines.
THE IMMUNOLOGICAL LEGACY OF OBESITY ON VIRAL PATHOGENESIS

Summary
Obesity is a key risk factor for severe viral infections. Our preliminary data suggest that in mice this susceptibility is not reduced by weight loss. In this grant we will investigate a) the mechanisms driving the legacy effect of obesity on antiviral immunity b) whether or not we can reverse this legacy effect by treatment with the drug MCC950 and c) the antiviral response of overweight children and adults who have and haven't recently lost weight.
Influenza A Viral Infection And Pregnancy Complications

Summary
Pregnant women who contract influenza are 5 times more likely to be hospitalised than the general population. Babies of mothers with influenza are also associated with increased perinatal mortality rates. We hypothesise that influenza infection in pregnancy significantly impairs the maternal vascular system resulting in maternal and foetal morbidity. Outcomes from this research may change current treatment modalities to improve maternal and foetal outcomes complicated by influenza infection.
Oleoyl-ACP-hydrolase As An Early Predictive Biomarker For Severe And Fatal Influenza

Funding Amount

Summary
Millions are hospitalized with severe influenza disease and ~500K die annually but the underlying mechanisms that drive disease are still not fully understood. We have identified a key role for an enzyme involved in fatty acid metabolism, which is profoundly elevated in patients who succumb to influenza and is thus a predictor for fatal outcomes. This research aims to investigate how this enzyme affects infection and impairs immune responses to drive severe respiratory viral disease.
