Immune system is a complex self-adaptive system consisting of molecules

cells and organs.The process of recognizing

activating

responding to a special antigen is also a process of complex dynamics.In order to understand how dynamics behavior of individual agent propagates to population dynamics

it presents a new method of researching agent population dynamics which is inspired by T cells immune response.The model of T cell agents is established by hybrid model of differential equation and cell automaton.It sets up the base for studying the relation between individual dynamics of T cell and population dynamics of T cells.
