Abstract
Angiotensin-(1-7) [Ang-(1-7)] is a biologically active peptide of the renin–angiotensin system (RAS) that counterbalances the actions of angiotensin II (Ang II), primarily through binding to the Mas receptor (MasR). This axis exerts significant immunomodulatory effects by influencing several features of leukocytes, including macrophage function, a central component in the resolution of inflammation. Macrophages contribute to tissue homeostasis by clearing apoptotic cells, releasing anti-inflammatory mediators and supporting tissue repair. Herein, we highlight the evidence supporting the role of Ang-(1-7) in guiding macrophages toward inflammation resolution. In this context, Ang-(1-7)/MasR signaling has been shown to induce several functions in macrophages, including suppression of pro-inflammatory activity, enhancement of apoptotic cells efferocytosis and bacterial phagocytosis, and promotion of macrophage polarization toward regulatory phenotypes.
