Description of the Model

We aim to create a quantitative computational model of the cutaneous lipid signalling networks, including variables such as multiple lipid substrates and enzyme isoforms. Model construction will be guided by literature studies, combined with new experimental lipidomics data collected in this project. In order to analyse model properties, experimental studies such as altering the systemic availability of fatty acids and the effect upon the anti-inflammatory milieu will be measured. This information will be integrated into the model to obtain estimated kinetic parameter values and also to validate and refine the overall model topology. The resulting mathematical model will be testable and predictive of the lipid responses during inflammation. The insights obtained will allow for more targeted experiments to be designed in order to better understand skin lipid biology and to aid in the mapping of lipid networks contributing to inflammation. This will ultimately support the design of interventional studies to combat skin disease.

A detailed network of the stimulated arachidonic acid cascade in human skin cells. The metabolites are shown in green rectangles and the enzymes are shown in blue rectangles. The numbered arrows between the metabolites represent the reaction number. The arrows in bold represent the enzyme catalysed reactions, the normal arrows represent non-enzyme catalysed reactions. The degradation and extracellular transport reactions are not shown for simplification purposes. For the full names of the metabolites and enzymes please refere to the abbreviations list.
