[New aspects of the theory inflammation (immune inflammation)]

Immune inflammation (II) arises on the basis of immunopathological mechanisms and acquires certain qualitative and quantitative features. It develops in a sensitized host following a specific immune response. Several kinds of II are to be distinguished differing from each other by the prevalence of disorders in cellular or humoral immunity, the pattern of the antigen, involvement in the response of immunoglobulins of different classes, complement components and a set of mediators. According to Sell's scheme, six immunopathological mechanisms are distinguished which underlie the development of early (like immediate type hypersensitivity) or late (like delayed type hypersensitivity) immune inflammation. Sometimes humoral and cellular mechanisms alternate in II which is reflected in the morphological picture of inflammation. This is illustrated by an example of the study of tissue inflammatory reactions in the synovial membrane in rheumatoid arthritis. Immune inflammation shows a trend to self-reproduction and continuous course with periods of remission and exacerbation of different durations. Timely recognition of immune inflammation is important both theoretically and practically.
