A Novel Molecular Mechanism Controlling Myelopoiesis

Summary
The immune system is comprised of many different cell types, each with a specialised function. Many are short-lived and must be continually replenished throughout life. Abnormalities in this process underlie many human diseases, including immunodeficiency, autoimmunity and cancer. We have discovered a novel molecular mechanism that is critical for the production of immune cells. This project will investigate how this mechanism is controlled and the impacts on myelodysplastic syndromes.
The Mezzanine T Cell Response: Intervening At The Coal Face

Summary
In an initial immune response, specialised cells in lymph nodes tell T cells to multiply; the stimulated T cells depart and enter target tissue (e.g. lung in the case of flu). We describe a new response whereby the target tissue itself can tell T cells to multiply further. This response in target tissues reveals a new way of altering immune responses. This is especially important as in many diseases, the primary lymph node response has already occurred, so cannot be therapeutically intervened.
Controlling Life And Death Of Dendritic Cell Subsets For Immunomodulation

Summary
Dendritic cells are pivotal in orchestrating immune responses; for example, they can turn immune cells into assassins to kill virus infections. Their function is so diverse that different dendritic cells do different jobs. There are many genes that control life and death of cells but those that are important for each specialised dendritic cell have not been comprehensively studied. Drugs that affect the proteins made by such genes selectively may be a new way of controlling immune responses.
