Sammanfattning

Innate and adaptive immunity has evolved as a defence against infections and as an important repair mechanism after physical injury. If elimination of microbes and healing is not achieved, or if the immune system is dysregulated, chronic inflammation ensues. Immune cells become engaged in prolonged reactions with other cell types in vessels and organs, frequently with superimposed autoreactive T-cells and autoantibody-producing B-cells/plasma cells. The processes are distinguished on the basis of clinical manifestations in organ-specific and systemic inflammatory diseases. The underlying factors of these diseases are generally unknown.
