Summary
There are 2 types of immune cells, innate cells reacting broadly against microbial elements, and adaptive cells educated to remember pathogens and provide improved immune responses. Most treatments against lupus target the adaptive cells with mixed success. We have discovered a new mechanism driving lupus at the level of innate immunity. This proposal will identify molecular players driving this unappreciated form of lupus and validate new therapeutic targets.
Cytoplasmic DNA As A Danger Signal For Mammalian Cells

Summary
DNA in mammalian cells is contained within a structure known as the nucleus. The presence of DNA outside the nucleus in the cytoplasm of the cell is a sure sign that something is wrong, and may indicate the presence of a viral invader. In this case, the cell initiates anti-viral responses, including production of anti-viral proteins and death of the infected cell to stop replication of the virus. Lack of proper control of these responses may contibute to the autoimmune disease lupus.
