Role of local angiotensin II signaling in bladder function

Area of Science:

• Urology
• Physiology
• Pharmacology

Background:

• Local angiotensin II signaling is crucial in various diseases but its role in the urinary bladder remains under-investigated.
• The urinary bladder exhibits local angiotensin II signaling, with identified angiotensin type 1 and type 2 receptors in human and animal tissues.

Purpose of the Study:

• To review and synthesize current literature on local angiotensin II signaling in the urinary bladder.
• To highlight the functional roles and implications of this signaling pathway in bladder physiology and pathology.

Main Methods:

• Comprehensive review of existing scientific literature spanning several decades.
• Analysis of studies investigating angiotensin II signaling components and their effects in bladder tissues and disease models.

Main Results:

• Strong evidence supports the presence and expression of angiotensin type 1 and type 2 receptors in the bladder.
• Angiotensin type 1 receptor activity is implicated in mediating bladder contractions and is upregulated in bladder disease models.
• Angiotensin II signaling is associated with increased inflammation, fibrosis, and oxidative stress in the bladder.

Conclusions:

• Local angiotensin II signaling plays a significant role in bladder function and disease.
• Gaps in knowledge, particularly regarding clinical translatability, necessitate further investigation.
• Continued research is essential to fully understand and leverage angiotensin II signaling for therapeutic applications in bladder conditions.
