A chemical compound that blocks receptors for advanced glycan end-products (RAGE) appeared to reduce inflammation associated with COPD and other lung diseases in a mouse model.
The researchers injected mice with an in vivo COPD inducer and the RAGE antagonist FPS-ZM1. Then they assessed the infiltrated inflammatory cells and their production of cytokines. Cellular expression of RAGE, initiating inflammatory response, and soluble RAGE, acting as a “decoy,” was determined in protein, serum, and bronchoalveolar lavage fluid in the mice, as well as in the serum of human donors and patients with COPD.
