Special Issue Information

Dear Colleagues,

Degenerative diseases of the retina continue to be a leading cause of vision loss, especially in an aging population. Although recent clinical advances, such as the use of inhibitors and blockers of various growth factors, have provided ophthalmologists with clinical tools of considerable efficacy, there is still a critical need for definitive treatments. Further advances in the treatment of retinal degeneration will require a deeper understanding of the molecular pathophysiology of these diseases. This Special Issue will promote this goal by highlighting notable advances in the diagnosis and therapy of retinal degenerative (RD) disease. In the area of retinal disease diagnosis, contributions are invited that feature innovations and advances in such areas as molecular diagnostics, imaging (especially applied to biomolecular detection), applications of artificial intelligence or informatics to assist in complex diagnoses, and innovative approaches that are based on multifactorial diagnostic indicators. Complementing the diagnostic aspects, this issue also invites contributions describing transformative and realistic cutting-edge approaches to the treatment of RD diseases, which have a potential to ameliorate RD, alleviate vision loss, and even restore sight. Gene therapies, neuroprotection, in vivo gene editing, retinal replacement, regeneration, immunomodulation, and therapeutic monoclonal antibody modalities to managing the RD diseases are all welcome in this Special Issue. Authors are requested to discuss the molecular, cellular, tissue or/and systemic mechanisms of therapies of the approaches outlined in each manuscript.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.

Abstract
The neurovascular unit (NVU) plays an essential role in the development of diabetic retinopathy (DR). We previously reported that the topical administration (eye drops) of sitagliptin and saxagliptin, two dipeptidyl peptidase-4 inhibitors (DPP-4i), prevents retinal neurodegeneration and vascular leakage in db/db mice.

The neurovascular unit (NVU) plays an essential role in the development of diabetic retinopathy (DR). We previously reported that the topical administration (eye drops) of sitagliptin and saxagliptin, two dipeptidyl peptidase-4 inhibitors (DPP-4i), prevents retinal neurodegeneration and vascular leakage in db/db mice. The aim of the present study is to evaluate the minimum effective dose of the topical administration of these DPP-4i. For this purpose, sitagliptin and saxagliptin were tested at different concentrations (sitagliptin: 1 mg/mL, 5 and 10 mg/mL, twice per day; saxagliptin: 1 and 10 mg/mL, once or twice per day) in db/db mice. As end points of efficacy, the hallmarks of NVU impairment were evaluated: reactive gliosis, neural apoptosis, and vascular leakage. These parameters were assessed by immunohistochemistry, cell counting, and the Evans blue method, respectively. Our results demonstrated that the minimum effective dose is 5 mg/mL twice per day for sitagliptin, and 10 mg/mL twice per day for saxagliptin. In conclusion, this study provides useful results for the design of future preclinical regulatory studies and for planning clinical trials. Full article
