Immune activity has a benefit and a cost. The negative side of immunity is the production of distressing symptoms, acute and chronic diseases. The term hypersensitivity describes increased, damaging immune response. If you read a textbook of immunology, you get the impression that immune activity only happens occasionally when an infection threatens or an obvious allergic response occurs. You may not realize that immune activity is continuous and is likely to generate symptoms in every person on a regular basis. You do learn from the immunology text that there are many hypersensitivity diseases. You do not learn that non-specific hypersensi

IgG is the major circulating antibody which enters tissues freely, and participates in diverse immune events. The IgG antibodies represent a large vocabulary of antigen

antibodies. These cells belong to many different functional groups which interact in a complex way, resembling a large military organization. Some T-Lymphocytes (Killer cells or K-cells) act directly to attack cells identified by specific antigen and are responsible for cell-mediated delayed immune-injury.
