AI Article Synopsis
- The retina consumes more energy than any other tissue in the human body and primarily uses aerobic glycolysis, producing significant amounts of lactate.
- The study compared two techniques for measuring lactate release from cultured retinal explants, finding consistent results between a standard assay kit and H-NMR spectroscopy.
- It was observed that degenerating rd1 mouse retina released more lactate than healthy wild-type retina, suggesting a higher energy demand in damaged retinas.
Article Abstract
The retina has the highest energy consumption of any tissue in the human body. Remarkably, to satisfy its energy demand, the retina appears to rely mostly on aerobic glycolysis, which results in the production and release of large amounts of lactate. In the present study, we compared two different methods to assess lactate release from in vitro organotypic retinal explants cultured under entirely controlled, serum-free conditions. We used a standard lactate assay kit and H-nuclear magnetic resonance (NMR) spectroscopy-based analysis. We found that during the culturing of retinal explants derived from wild-type mice, lactate was released in large amounts and that the two different methods agreed well with each other. When comparing wild-type retina with degenerating rd1 mouse retina, we found the latter to release significantly higher amounts of lactate. Hence, degenerating retina may have an even higher energy demand and metabolic rate compared to healthy retina. We conclude that the use of lactate measurement can be a reliable and simple readout to evaluate ongoing retinal metabolism.

A Penetrable AAV2 Capsid Variant for Efficient Intravitreal Gene Delivery to the Retina.

Department of Ophthalmology, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Purpose: This study aimed to identify a novel recombinant adeno-associated virus (rAAV) capsid variant that can widely transfect the deep retina through intravitreal injection and to assess their effectiveness and safety in gene delivery.
Methods: By adopting the sequences of various cell-penetrating peptides and inserting them into the capsid modification region of AAV2, we generated several novel variants. The green fluorescent protein (GFP)-carrying variants were screened following intravitreal injection.

Retinitis Pigmentosa (RP) is a heterogenous group of inherited disorder, and its progression not only affects the retina but also the primary visual cortex. This manifests imbalances in the excitatory and inhibitory neurotransmission. Here, we investigated if changes in cortical functioning is linked to alterations in GABAergic population of neurons and its two important subsets, somatostatin (SST) and parvalbumin (PV) neuron in model of retinal degeneration (RD).

Article Synopsis
- The study evaluated the impact of a viral vector-delivered multi-characteristic opsin (MCO-010) on vision in two mouse models of retinitis pigmentosa (rp1 and rp10), focusing on both structural and functional outcomes.
- MCO-010 was injected into the eyes of the mice, resulting in successful transduction of about 80% of bipolar cells without affecting retinal thickness, while control mice showed thinning.
- The treatment improved behavior and visual response in the mice without causing toxicity under challenging conditions, suggesting it could help slow retinal degeneration.
Host-Graft Synapses Form Functional Microstructures and Shape the Host Light Responses After Stem Cell-Derived Retinal Sheet Transplantation.

Purpose: Retinitis pigmentosa represents a leading cause of blindness in developed countries, yet effective treatments for the disease remain unestablished. Previous studies have demonstrated the potential of stem cell-derived retinal organoid (SC-RO) sheet transplantation to form host-graft synapses and to improve light responsiveness in animal models of retinal degeneration. However, the detailed microstructures of these de novo synapses and their functional contribution have not been well elucidated.
