The renin angiotensin system and the metabolic syndrome

Area of Science:

• Endocrinology and Metabolism
• Cardiovascular Physiology
• Neuroscience

Background:

• The renin-angiotensin system (RAS) is crucial for cardiovascular and hydromineral balance.
• Emerging evidence implicates the RAS in metabolic syndrome, potentially linking obesity to comorbidities.
• Angiotensin-II (A-II) is the primary effector peptide of the RAS.

Purpose of the Study:

• To review the multifaceted roles of the RAS in metabolic disorders.
• To highlight the specific influence of the RAS on body weight regulation.
• To summarize actions of the RAS in the brain and peripheral tissues related to metabolism.

Main Methods:

• Literature review of existing research on the RAS and metabolic syndrome.
• Analysis of studies investigating the RAS's role in obesity and insulin resistance.
• Synthesis of findings on RAS actions in the central nervous system and peripheral tissues.

Main Results:

• RAS plays a significant role in metabolic syndrome, connecting obesity with other health issues.
• Pharmacological inhibition of angiotensin-II (A-II) synthesis or action shows efficacy in preventing insulin resistance.
• The RAS influences body weight regulation through actions in various body tissues.

Conclusions:

• The RAS is a key player in metabolic regulation and body weight control.
• Targeting the RAS offers potential therapeutic strategies for metabolic syndrome and obesity.
• Further research into the brain and body actions of the RAS is warranted.
