Abstract:
The impaired elimination of self-reactive T cells is one factor that contributes to autoimmunity. Although the mechanism of thymic negative selection has been studied for decades, recent data demonstrate that the mechanisms underlying this fundamental process remain extremely controversial. Nonetheless, new models such as the Aire-deficient mice have demonstrated the importance of thymic negative selection in autoimmune disease progression in mice and humans.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
