Competition Funded PhD Project (European/UK Students Only)
An increasing body of evidence is linking microbiome composition with human health. Chronic inflammatory diseases, such as allergy and asthma, have been associated with dysbiotic microbiomes at both the gut and the respiratory niches. Nevertheless, causality, key underlying mechanisms as well as the prognostic potential of these associations are just starting to get explored. Some of the first data in relation to the elusive viral component of the respiratory microbiome – the virome – and its dysbiotic properties, have been explored by our group in the context of the Horizon2020 project CURE. A key finding is a deficiency of prokaryotic viruses in asthma; (bacterio)phages who have the capacity of regulating the bacterial composition of the microbiome and thereby contribute to an ‘anti-inflammatory’ signalling, are reduced in number and diversity. However, phages do not appear to have direct effects on most of the human immune cells or the respiratory mucosa. It remains completely unknown if and how viral composition and signalling may interact with the host immune system and whether this has an influence on the defective immunity and exaggerated inflammation observed in asthma.
This project aims at understanding the mechanisms of interactions between the dynamic composition of microbiological communities in the respiratory tract with the immune environment they help shape and vice-versa, as well as how this may be reflected in clinical symptoms.
Specific goals include:
1. Correlating microbiological with immunological as well as clinical data obtained in the course of the longitudinal CURE project
2. Modelling potential effects of key immune components, such as interferons, on viral-bacterial interactions, and confirming the results in cellular models
3. Assessing the in-vitro effects of microbiological components on immune cell maturation and related responses.
The student will interact with the CURE team, gaining invaluable insight on medical, immunological, virological and ecological aspects of dysbiosis in a chronic inflammatory disease such as asthma, with the potential of expanding it to similar pathophysiologies. The project is interdisciplinary and intensely quantitative. The student would benefit from excellent training in bioinformatics, mathematics, immunology and biology. They will be encouraged to specify their own research directions and explore novel approaches.
