The liberation of free AA from the phospholipid membrane. As this reaction is performed by a multitude of isoforms of PLA2, all with unique kinetics, this reaction was simplified.

Parameter Name | Parameter Shorthand | Initial Value | Justification |
---|---|---|---|
Doubling time of the AA event | AADT | 420 min | AA was set to be released for 6h, as this was the length of the inflammatory window in the modelled system. This value was not changed in the modelled scenarios. |
Maximum concentration of AA | c | 0 mM | The adapted value of this parameter depends on the scenario (Table *). This value changes 60 min into the simulation for all scenarios. |
Decay switch | c2 | 0 | If required the production of AA can decrease over time by amending this value from 0 to 1. This was set to 0 in all scenarios. |
Half-life of the AA event | AAHL | 420 min | This value was arbitrarily set at 420 min. However, no simulations required AA release to decrease over time. |
