Abstract
MHC class II molecules play a fundamental role in the homeostasis of the immune response, functioning as receptors for antigenic peptides to be presented to regulatory T cells. Both quantitative and qualitative alterations in the expression of these molecules on the cell surface dramatically affect the onset of the immune response, and may be the basis of a wide variety of disease states, such as autoimmunity, immunodeficiencies, and cancer. Most regulation of MHC class II molecule expression is under the control of transcription mechanisms which are both cell type and development specific. In the last few years classical genetics together with molecular biology have greatly contributed to the widening of our knowledge on the regulatory mechanisms operating in the control of class II gene expression. This review deals with the latest developments in this fundamental area of immunology.
