چکیده انگلیسی
In this research we study early events in signal transduction including receptor/ligand binding and G-protein activation using an ordinary differential equation model. Motivated by experimental data and the mathematical model proposed by Chen et al. [C.Y. Chen et al., Modelling of signalling via G-protein coupled receptors: pathway-dependent agonist potency and efficacy, Bull. Math. Biol. 65 (2003) 933-958] to explain the agonist potency and efficacy of drugs regulated by signaling dynamics via G-proteins and receptors, we extended their model to take into account internalization, recycling, degradation and synthesis of the receptors in this process to obtain a more realistic model. By analyzing the extended model, we have found that the numerical results agree well with experimental observation. Qualitatively, this modified model is shown to be more realistic than the previous one in some respects when certain experimental findings are considered.
