Abstract
The vertebrate immune system protects the host from a wide variety of pathogens, including bacteria, viruses, fungi, and parasites. However, this remarkable versatility comes at the cost of autoimmune and autoinflammatory diseases that affect approximately 1 in 30 individuals. This chapter briefly reviews the cardinal molecular and cellular features of the immune system, including the molecular basis of recognition and response to pathogens, mechanisms of tolerance, and immunological memory. Knowledge of the immune system is critical to understanding rheumatologic disease. While the detailed pathophysiology of major autoimmune diseases remains elusive, genetic immune disorders and the effects of new biologic targeted treatments provide insights into many of the mechanisms of immunological disease.
