Special Issue Information
Dear Colleagues,
The retina is one of the most metabolically active tissues in the body, its different cell types organized in layers with close metabolic symbiotic exchanges between the cellular components. In particular, the retinal pigment epithelium (RPE) supplies nutrients from the choroidal vasculature to all retinal cellular components. However, the high metabolic demands depend on the nutrient supply. Therefore, the retina may be considered a metabolic ecosystem in which RPE cell dysfunction may compromise the function and viability of other retinal cells. RPE can use a lot of fuels, such as glucose, amino acids, lactic acid, and lipids, to produce energy. The disruption of the local energy supply may affect the redox balance, contributing to a disrupted retinal homeostasis. Moreover, metabolites affect epigenetic modifications, linking the cellular metabolism to transcriptional activity.
It is well known that the pathogenesis of retinal diseases, including age-related macular degeneration and diabetic retinopathy, is associated with retinal metabolism dysregulation. This Special Issue aims to provide new insights into the metabolic mechanisms at the basis of retinal diseases, supporting new therapeutic targets.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
