① Lymphocyte: a T-lymphocytes cytotoxic T cell: Tc C-kill the tumor cell, virus infective cell and foreign cell helper T cell: Th C- promotes activity of BLC and Tc c suppressor T cell: TSC-regulate the function of blc and tc b B-lymphocytes: become into plasma cell C. NK cell: counteract virus infective cell and tumor cell
