Introduction

Previous chapters discussed the concepts of immunogenicity and antigen presentation by immunocompetent cells. The present chapter explores the concept that the immune system is activated or deactivated by surface receptor interactions and subsequent intracellular signaling. Much like starting an automobile, several signals must be given in a defined sequence to override interlocking safety systems. When the immune system is stimulated, T and B cells give each other signals in a defined pattern. Because there is a possibility of uncontrolled proliferation during activation, the immune response is tightly controlled. If an improper signal is given, cellular proliferation is prevented and the cell undergoes programmed cell death or apoptosis.
