Immune complex detection by immunofluorescence on polymorphonuclear leucocytes : an experimental and clinicopathological study
Diseases, which are the result of immune reactions associated with tissue damage may be caused by several mechanisms. The immunologic mechanisms resulting in tissue damage have been categorized in 4 types (Gell and Coombs, 1968). 1. the anaphylactic type, mediated by IgE type of antibodies, resulting in immediate release of vasoactive arnines (e.g. histamine). 2. the cytotoxic type, mediated by IgG and IgM type of antibodies and resulting in phagocytosis of the target cells or lysis by complement activation. 3. the immune complex type, with either primary localisation of the immune complexes in the tissues (Arthus reaction) or circulating immune complexes with secondary tissue localisation. 4. the delayed type or cellular immune response mediated by thymus derived T-lymphocytes. In the studies to be reported, only diseases caused by the type 3 reaction, mediated by circulating immune complexes, are of concern. Examples of human diseases caused by the immune complex mediated type of tissue damage are a.o. serum sickness, systemic lupus erythematosus (SLE) and several types of glomerulonephritis.
