The role of interferon gamma and nitric oxide as downregulating molecules in central nervous system inflammation

Funded Activity Summary

Cytokines are soluble factors which participate in inflammatory responses. Interferon gamma is a cytokine which in the context of central nervous system inflammation has been considered a Obad? molecule, as has the gas nitric oxide which is induced by interferon gamma. We now have direct evidence that indicate quite the contrary, ie interferon gamma and nitric oxide can a do act as down regulators of inflammation. The present work is designed to determine if this down regulating function is restricted only to a single model of CNS inflammation or is a general phenomenon within the CNS. The project will also involve a number of experiments designed to elucidate the mechanism(s) by which down regulation occurs. This project is highly significant in that a single uncontrolled clinical trial of interferon gamma for the therapy of MS has been carried out and reported as indicating that interferon gamma made the disease worse. The design of that trial however was such that the validity of that claim is questionable. If our experiments confirm the general nature of interferon gamma as a down regulator in inflammation in a number of different models of MS then a case for revisiting the use of interferon, or a downstream product of interferon, in the therapy of MS might be made.
