Sarah Doyle

Assistant Professor of Immunology

Sarah completed her PhD on Toll-like Receptor (TLR) signalling pathways under the supervision of Professor Luke O’Neill in the Dept. of Biochemistry, Trinity College Dublin (TCD) in 2007. Since then Sarah’s scientific interests have centred on the molecular dialogue associated with how the immune system recognises injury, reacts, and directs an inflammatory response to resolve insult. One major aspect of her research focuses on elucidating the cellular mechanisms and signalling events that regulate the effects of Pattern Recognition Receptor (PRR) responses, in particular the TLRs and NLRs of the innate immune system, to both pathogen-derived and endogenous damage-associated immunomodulators. Sarah worked as a post-doctoral research fellow in the School of Biochemistry and Immunology in TCD between 2007 – 2012 with time spent in NTNU, Norway in 2008 and again in 2010. In 2012, Sarah was recruited as an Assistant Professor and Lecturer in Immunology in the School of Medicine with a position in the Dept. of Clinical Medicine.

Role:
Kiva studies immune signalling pathways activated after infection or injury in neonates and infants.

Developmental changes in Pattern Recognition Receptor activity as the innate immune system develops from birth through infancy into childhood and adolescence.

Developmental changes in Pattern Recognition Receptor activity as the innate immune system develops from birth through infancy into childhood and adolescence. Summary: Human neonates and young infants are more vulnerable to certain infectious agents than older children and adults, and are especially susceptible to infections with intracellular pathogens. Due to the requirement of the adaptive immune system for immunological experience, the innate immune system, and its Pattern Recognition Receptors (PRRs), represent the critical front-line defense against these pathogens. This project aims to assess which pathways activated by these PRRs are altered in the “immature” innate immune system and furthermore, how, and at what stage, they develop into a mature innate response; information generated should lead to improved age-appropriate therapies for infectious and inflammatory childhood diseases.

Improving vaccine responses in the paediatric population by harnessing Pattern Recognition Receptor responses to promote Th1- and Th17-cell polarisation.

After clean water, vaccination is the most effective public-health intervention, yet despite global efforts, 2 million children die each year from infectious diseases before they reach 1 year. The challenge to early-life vaccination is that immune-responsiveness varies with age with evidence suggesting that responses elicited by the immune system of infants and young children are compromised, when compared with those in adults. This is due to the fact that the molecular rules that govern how the adult immune system responds to certain stimuli, called “adjuvants”, do not necessarily apply to the “developmentally-young” immune system. This project aims to build on our previous NCRC funded research to assess which immune-responses are functional in infants and children and, furthermore, to pinpoint the stimuli that result in a robust immune response. Information generated will lead to improved age-appropriate “adjuvants” for vaccine-preventable diseases potentially eliminating the need for booster injections and closing the “window of vulnerability” preventing life-threatening invasive infection in early life.
