We showed that adoptive transfer of Tregs in recipient mice blocked angiotensin II perfusion-induced abdominal aortic aneurysms (140), induced β3-adrenergic receptor agonist-induced adipose tissue thermogenic program (141), and blunted the development of spontaneous systemic lupus erythematosus (142). The gene discussed is AGT; the disease is systemic lupus erythematosus.
