报告摘要:First, we propose a new ODEs model of interactions between tumor cells, M1 and M2 macrophages, and study the stability and bifurcations around the interior equilibrium. It is shown that the model exhibits stable periodic oscillations bifurcating from Hopf bifurcation, which indicates the long-term coexistence of tumor cells, M1 and M2 macrophages as well as long-term tumor relapse. Secondly, we incorporate M1 macrophages activation delay and M2 macrophages activation delay into previous ODEs model. The new findings show that M1 macrophages activation delay can only destabilize the interior equilibrium. However, M2 macrophages activation delay can not only destabilize the interior equilibrium but also stabilize the interior equilibrium. Several bifurcation diagrams are provided to support the theoretical results.
