Molecular signaling pathways controlling gene expression during chronic disease progression
Inflammation is increasingly being seen to have a significant impact on many chronic diseases such as arthritis, cancer, Alzheimer’s disease, obesity/type II diabetes and heart diseases. The socio-economic burden of inflammatory diseases is enormous both in terms of direct health care costs and indirect non-health care costs.
Granulocyte macrophage-colony stimulating factor (GM-CSF) is a prosurvival factor for monocytes/macrophages, but also act as a proinflammatory cytokine. Thus, GM-CSF has been targetted in a number of clinical trials associated with inflammation. However, this may lead to undesirable side-effects, such as infections, given its role in prosurvival of immune cells. We are examining GM-CSF-mediated molecular signalling pathways controlling the expression of inflammatory genes critical for the progression of such inflammatory diseases.
