A recent study published in the PNAS Nexus explored how diabetes affects the biomechanics of intervertebral discs that can offer crucial insights into spinal health. This study utilized advanced imaging techniques to investigate the behavior of collagen within the discs to uncover significant implications for both understanding disease mechanisms and developing potential treatments.

Synchrotron small-angle X-ray scattering was used to examine how alterations in collagen behavior contribute to changes in the ability of discs to resist compression. This research focused on comparing the discs of lean Sprague-Dawley rats to those of diabetic obese University of California Davis type 2 diabetes mellitus (UCD-T2DM) rats.

The research team identified two primary mechanisms discs from lean rats that enable resistance to compression at the nanoscale with the rotation of collagen fibrils within the annulus fibrosus and straightening and stretching of these fibrils. In discs from diabetic rats, both mechanisms were significantly impaired.

The study also revealed a 31% reduction in fibril rotation and a 30% decrease in collagen fibril strain in diabetic rat discs when compared to lean counterparts. This impairment was attributed to a stiffening of collagen fibrils that was evidenced by a 31% higher concentration of nonenzymatic cross-links in discs from diabetic rats.

Also, diabetic rat discs displayed earlier onset plastic deformations, like the fibril sliding and fibril-matrix delamination which indicates a compromised ability to withstand compression over time. These findings enables with understanding disc degeneration associated with aging and diabetes. The study paves way for targeted interventions to preserving spinal health by elucidating the key deformation mechanisms involved in whole-disc compression and highlighting how diabetes disrupts these processes.
