Ang‐(1‐7) and the synthetic Mas receptor agonist AVE 0991 have been effective in a number of inflammatory models, such as arthritis (da Silveira et al., 2010), asthmatic lung inflammation (Rodrigues‐Machado et al., 2013) and renal inflammation (Silveira et al., 2013). Here, ANG is linked to arthritic joint disease.
