Аннотация
The imbalance of the immune system can lead to the occurrence of autoimmune diseases. Controlling and regulating the proliferation and function of effector T (Teff) cells and regulatory T (Treg) cells becomes the key to treating these diseases. Dendritic cells (DCs), as dedicated antigen-presenting cells, play a key role in inducing the differentiation of naive CD4+ T cells. In this study, we designed a cationic lipid-assisted PEG-PLGA nanoparticle (NPs/VD3/siLkb1) to deliver 1,25-dihydroxyvitamin D3 (VD3) and small interfering RNA (siRNA) to DC cells in the draining lymph nodes. By modulating the phenotypic changes of DC cells, this approach expands Treg cells and reduces the occurrence of autoimmune diseases. Thus, this study provides a novel approach to alleviating the occurrence and development of autoimmune diseases while also minimizing the risk of unwanted complications.
