The spleen--still a puzzling organ?

Abstract

The model of animal experiments developed in the sixties by the Erfurt investigation team of A. Sundermann, according to which autoimmunisation phenomena may be evoked in the rabbit by the application of warmth-alterated autologous blood cells, undergoes a repeated critical consideration on the basis of the modern knowledge of the nature of the autoimmunisation process. In this case must be stated that the importance of the spleen for the development of such processes is finally still unclear. The favourable therapeutical effects of a splenectomy observed in the model and also in clinical routine work cannot be explained sufficiently theoretically, particularly on the basis of the recent results of research concerning the cellular immune mechanisms. No doubt, it seems to be clear that the spleen is authoritatively responsible for the primary immune response, however it remains questionable, whether an isolated primary response is really existing, since on its part it already depends on T-lymphocytes which stimulate the secondary response. However, a splenectomy might be suitable theoretically--if at all--for the interruption of the immune process only in the stage of the primary reaction. In the complex process within the immun...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
