Abstract:
The present invention relates to methods and compositions for inhibiting pancreatic cell dysfunction and Fas-mediated apoptosis. The invention relates to recombinant vectors, including viral vectors, comprising nucleic acids molecules encoding inhibitors of interleukin-1 (IL-1) and Fas-mediated apoptosis and the use of such vectors for transfer of said nucleic acid molecules into cells. The invention encompasses genetically engineered cells comprising nucleic acid molecules encoding inhibitors of IL-1 signal transduction. The invention further relates to methods for transplanting such genetically engineered cells into a host recipient with a pancreatic disorder. The methods and compositions of the invention may be used to reduce Il-1 mediated cell dysfunction and apoptosis, thereby reducing the insulitis associated with pancreatic disorders such as insulin dependent diabetes mellitus (IDDM).
