Isolation and Adoptive Transfer of High Salt Treated Antigen-presenting Dendritic Cells

Excess dietary salt intake contributes to inflammation and plays a vital role in the development of hypertension. We previously found that antigen-presenting dendritic cells (DCs) can sense elevated extracellular sodium leading to the activation of the NADPH oxidase and formation of isolevuglandin (IsoLG)-protein adducts. These IsoLG-protein adducts react with self-proteins and promote an autoimmune-like state and hypertension. We have developed and optimized state-of-the-art methods to study DC function in hypertension. Here, we provide a detailed protocol for isolation, in vitro treatment with elevated sodium, and adoptive transfer of murine splenic CD11c⁺ cells into recipient mice to study their role in hypertension.
