Professor Luke O'Neill
The group of Prof O誰eill is investigating the molecular and cellular basis to inflammation and innate immunity. Particular areas of interest include Toll-like receptors, proinflammatory cytokines, signal transduction in the immune system, and molecular analysis of inflammatory and infectious diseases.
Figures of Research Work This figure depicts the 4 major families of pathogen sensors that sense the microbial world during infection, triggering signalling pathways that culminate in increased expression of immune and inflammatory genes.
