A translational model of chronic diabetic nephropathy in the Nile grass rat.

Diabetic nephropathy (DN) is a major healthcare challenge for individuals with diabetes and associated with increased cardiovascular morbidity and mortality. The existing rodent models do not fully represent the complex course of the human disease. Hence, developing a translational model of diabetes that reproduces both the early and the advanced characteristics of DN and faithfully recapitulates the overall human pathology is an unmet need.

Role of Interleukin-21 in retinal ischemia-reperfusion injury: Unveiling the impact on retinal ganglion cell apoptosis.

Background: Retinal ischemia-reperfusion (I/R) serves as a significant contributor to ocular diseases, triggering a cascade of pathological processes. The interplay between neuroinflammation and the apoptosis of retinal ganglion cell (RGC) is a well-explored aspect of retinal I/R-induced tissue damage. Within this intricate landscape, the inflammatory cytokine Interleukin-21 (IL21) emerges as a potent mediator of neuroinflammation with known detrimental effects on neuronal integrity.

Breath Biopsy Reveals Systemic Immunothrombosis and Its Resolution through Bioorthogonal Dendritic Nanoprobes.

Immunothrombosis, an inflammation-dependent activation of the coagulation cascade, leads to microthrombi formations in small vessels. It is a dreaded complication of COVID-19 and a major cause of respiratory failure. Due to their size and disseminated nature, microthrombi are currently undetectable.

VEGFR-2 adhesive nanoprobes reveal early diabetic retinopathy in vivo.

Diabetic retinopathy (DR) is a debilitating organ manifestation of diabetes. Absent of early diagnosis and intervention, vision tends to drastically and irreversibly decline. Previously, we showed higher vascular endothelial growth factor receptor 2 (VEGFR-2) expression in diabetic microvessels, and the suitability of this molecule as a biomarker for early DR diagnosis.

microRNA-96 targets the INS/AKT/GLUT4 signaling axis: Association with and effect on diabetic retinopathy.

Background: miR-96-5p is a highly expressed microRNA in the retina of subjects with diabetes. The INS/AKT/GLUT4 signaling axis is the main cell signaling pathway of glucose uptake in cells. Here, we investigated the role of miR-96-5p in this signaling pathway.
