The regulatory network behind MHC class I expression

Inferring the regulatory network behind a gene expression experiment

Transcription factors (TFs) and miRNAs are the most important dynamic regulators in the control of gene expression in multicellular organisms. These regulatory elements play crucial roles in development, cell cycling and cell signaling, and they have also been associated with many diseases. The Regulatory Network Analysis Tool (RENATO) web server makes the exploration of regulatory networks eas...

Class I MHC expression in the yellow baboon.

MHC class I molecules play a crucial role in the immune response to pathogens and vaccines and in self/non-self recognition. Therefore, characterization of MHC class I gene expression of Papio subspecies is a prerequisite for studies of immunology and transplantation in the baboon (papio hamadryas). To elucidate MHC class I expression and variation within Papio subspecies and to further investi...

Baboon Class I MHC Expression in the Yellow Hildebrand

MHC class I multimers

T lymphocytes play a key role in the immune response to both foreign and self peptide antigens, which they recognize in combination with MHC molecules. In the past it has been difficult to analyse objectively the specificity, frequency and intensity of T cell responses. The recent application of fluorescent-labelled MHC class I multimers, however, has provided a powerful experimental approach t...

Regulation of MHC class I expression by Foxp3 and its effect on regulatory T cell function.

Expression of MHC class I molecules, which provide immune surveillance against intracellular pathogens, is higher on lymphoid cells than on any other cell types. In T cells, this is a result of activation of class I transcription by the T cell enhanceosome consisting of Runx1, CBFβ, and LEF1. We now report that MHC class I transcription in T cells also is enhanced by Foxp3, resulting in higher ...
