First, we detected the expression of autophagy-related genes (Atg5, Atg12 and Beclin 1) in the macrophages derived from activated lymphocytes-derived DNA (ALD-DNA) induced murine lupus as well as in the PBMC from SLE patients.
Our results suggest that DAI could function as a DNA sensor and a regulator in ALD-DNA-induced macrophage M2b polarization and lupus nephritis, providing the possible molecular mechanisms involved in ALD-DNA-induced macrophage M2b polarization in SLE disease and making DAI as a potential therapeutic target for the treatment of SLE.
