Red Blood Cells in Long-Term Type 2 Diabetes Patients Found to Harm Blood Vessels

A hidden timer ticks in type 2 diabetes patients: the longer they live with the condition, the more their own red blood cells begin sabotaging blood vessel health.

New research reveals a duration-dependent progression of vascular damage linked to type 2 diabetes, with a critical seven-year threshold marking the emergence of harmful properties in red blood cells.

Studies involving both animal models and human patients found that red blood cells from newly diagnosed individuals showed no adverse effects on blood vessels. However, after seven years of living with the condition, these cells began producing damaging effects.

The study, published in the journal Diabetes, identified microRNA-210 levels in red blood cells as a potential early biomarker for cardiovascular risk.

Zhichao Zhou said:

"It is only after several years that red blood cells develop a harmful effect on blood vessels."

Eftychia Kontidou added:

"If we can identify which patients are at greatest risk before vascular damage has already occurred, we can also become better at preventing complications."

These findings highlight a correlation between diabetes duration and vascular damage but do not establish causation. The study remains preliminary, and further research is needed before clinical applications can be developed.
