Brief description The identification of genetic variation in region of the DNA that controls expression of the inflammatory cytokine Tumour Necrosis Factor (TNF) and its association with a number of autoimmune and inflammatory diseases, has led to speculation that this genetic difference may play a role in predisposing some people to these diseases. We have isolated an activity, TPF1, that may regulate expression through interaction with this DNA control region. During the tenure of this grant we intend to clarify some of these questions, we will generate genetically modified mice that have either of the two genetic forms of the human TNF promoter. These mice will be compared in two models of associated disease, murine Lupus and cerebral malaria. We will also characterise the interactions of TPF1 with other components of the TNF control region. An understanding of the role of TPF1 in controlling TNF expression and an appreciation of the cell types that are able to express the phenotype, will allow the development of more subtle, cell specific strategies to modulate the activity of TNF without completely abolishing expression and may lead to better preventative and therapeutic strategies.
