Daniel Neill


I am a Tenure Track Fellow at the University of Liverpool.  My focus is on pathogens of the respiratory tract, particularly Streptococcus pneumoniae, but also including Pseudomonas aeruginosa and Respiratory Syncytial Virus.  Prior to my current position I studied Natural Sciences at the University of Cambridge and a PhD in Immunology at the MRC Laboratory of Molecular Biology, Cambridge.  Throughout my research career I have been driven by an interest in the complex and evolving relationship between pathogens and their hosts.


1. Understanding the role of immunomodulatory pathways in pneumococcal carriage and invasive disease. TGF beta and T regulatory cells are key mediators of pneumococcal carriage (Neill DR et al, Am J Resp Crit Care Med, 2014) but also protect the host against the development of invasive disease (Neill DR et al, PLoS Pathog, 2012).  My work aims to elucidate the key bacterial-host interactions that trigger the activation of regulatory immune responses.

2. Chronic Pseudomonas aeruginosa infection.  We have developed a novel model of long term P. aeruginosa infection (Fothergill JL et al, Nat Commun, 2014) which we are utilising to examine how seeding from the upper to the lower airways can lead to recurrent infections and how host immunity in chronic infection influences disease outcomes.

3. Helminth-pneumococcal coinfection.  I am interested in the impact of chronic helminth infection on pneumococcal disease epidemiology and disease susceptibility.
