Zusammenfassung: | Aims/Purpose: In the latest years neurodegeneration has been considered as one of the main pathological processes involved in proliferative diabetic retinopathy's (PDR) onset and progression. We aimed to increase the understanding on the role of the main signalling molecules that participate in this phenomenon, including apoptotic, excitotoxic and neurotrophic factor pathways.
Methods: Participants of both sexes were selected and programmed for vitrectomy by its diabetes mellitus 2 (DM2)‐derived vitreoretinal complications (PDR group, PDRG; n = 20), or by suffering macular hole, epiretinal membrane or rhegmatogenous retinal detachment (as the surrogate control group, SCG; n = 26). Vitreous body (VIT) and plasma (PLS) samples were collected and processed to determine the glutamate, caspase‐3 (CAS‐3) and brain‐derived neurotrophic factor (BDNF) levels. Next‐Generation Sequencing (NGS) techniques were applied to characterize the miRNA expression pattern in both groups.
Results: Significantly higher VIT glutamate (p |
