Mathematical Modeling Of Immune Responses To Hepatitis C Virus Infection, Ivan Ramirez
Mathematical Modeling Of Immune Responses To Hepatitis C Virus Infection, Ivan Ramirez
Electronic Theses and Dissertations
An existing mathematical model of ordinary differential equations was studied to better understand the interactions between hepatitis C virus (HCV) and the immune system cells in the human body. Three possible qualitative scenarios were explored: dominant CTL response, dominant antibody response, and coexistence. Additionally, a sensitivity analysis was carried out to rank model parameters for each of these scenarios. Therapy was addressed as an optimal control problem. Numerical solutions of optimal controls were computed using a forward-backward sweep scheme for each scenario. Model parameters were estimated using ordinary least squares fitting from longitudinal data (serum HCV RNA measurements) given in …
