Abstract
Autoimmunity is thought to emerge as a consequence of genetic predispositions and environmental tiggering factors. Often the etiology and the mechanisms involved in the autoaggressive destruction of self-components are rather complex and in many cases poorly understood. Chemokines and cytokines are central mediators of inflammatory processes that are involved in initiation and progression of autoimmunity. Many animal models for human autoimmune diseases use transgenic technology to express chemokines and/or cytokines in an organ or tissue specific manner. However, most of these model systems express the transgene irreversibly without considering the time of expression as a very important parameter. Here, we review experiences that were made from using a tetracycline-inducible promotor system (tTA-system) to express TNFα at various times during an ongoing autoimmune process, such as the destruction of pancreatic β-cells in a mouse model for human type 1 diabetes.
