Research Abstract

We have examined a role of autophagy in the regulation of innate immune response using mutant mice deficient in autophagy-related protein. We generated Atg9a-deficient mice and found that Atg9a controls dsDNA-induced innate immune response in embryonic fibroblasts. Because aberrant activation of innate immune response by dsDNA often results in the development of massive inflammation, a regulation of Atg9a function might be useful for the therapy of inflammatory disease induced by dsDNA.
