Bakshi2020 - Minimal model of alternative pathway of complement system


ABSTRACT: This model is based on the publication: "Mathematical Modelling of Alternative Pathway of Complement System". Suruchi Bakshi, Fraser Cunningham, Eva-Maria Nichols, Marta Biedzka-Sarek, Jessica Neisen, Sebastien Petit-Frere, Christina Bessant, Loveleena Bansal, Lambertus A Peletier, Stefano Zamuner, Piet H van der Graaf DOI: 10.1007/s11538-020-00708-z Comment: This model is based on the truncated minimal model equations (Eq. B.1) from the manuscript, which simulate depletion of factor H. Abstract: The complement system (CS) is an integral part of innate immunity and can be activated via three different pathways. The alternative pathway (AP) has a central role in the function of the CS. The AP of complement system is implicated in several human disease pathologies. In the absence of triggers, the AP exists in a time-invariant resting state (physiological steady state). It is capable of rapid, potent and transient activation response upon challenge with a trigger. Previous models of AP have focused on the activation response. In order to understand the molecular machinery necessary for AP activation and regulation of a physiological steady state, we built parsimonious AP models using experimentally supported kinetic parameters. The models further allowed us to test quantitative roles played by negative and positive regulators of the pathway in order to test hypotheses regarding their mechanisms of action, thus providing more insight into the complex regulation of AP.
