Diabetes and ageing-induced vascular inflammation

Area of Science:

• Cardiovascular Science
• Gerontology
• Endocrinology

Background:

• Aging and diabetes mellitus independently elevate cardiovascular disease (CVD) risk.
• Older adults with diabetes represent a growing population at high risk for CVD.
• Both aging and diabetes negatively impact vascular function, primarily through inflammation.

Purpose of the Study:

• To investigate the combined impact of aging and diabetes on vascular function.
• To explore the inflammatory mechanisms underlying exacerbated vascular impairment in older diabetic individuals.
• To identify potential therapeutic targets for preventing CVD in this population.

Main Methods:

• Review of functional and clinical evidence on vascular inflammation in aging and diabetes.
• Analysis of inflammatory pathways including cytokines, NF-κB, COX, iNOS, microRNAs, sirtuins, and Nrf2.
• Comparison of vascular impairment and CVD risk in aged, diabetic, and aged diabetic subjects (animal and human data).

Main Results:

• Aging and diabetes synergistically increase vascular impairment and CVD risk.
• Chronic low-grade inflammation in aging creates a pro-inflammatory vascular environment.
• This environment exacerbates diabetes-driven vascular damage mechanisms.

Conclusions:

• The co-existence of aging and diabetes leads to significantly higher vascular impairment and CVD risk.
• Specific inflammatory mechanisms driving this exacerbated vascular damage require further elucidation.
• Targeting these inflammatory pathways is crucial for developing effective interventions to prevent CVD in older diabetic patients.
