Special Issue Information

Dear Colleagues,

This call for papers is focused on any aspect of retinal ganglion cells (RGCs) biology, during development and in adulthood. RGCs are highly specialized projection neurons. They are responsible for carrying the luminous information, visual and non-visual, from the retina to the brain.

A small proportion of RGCs express the photopigment melanopsin, rendering them intrinsically photosensitive and able to directly detect light. They send light irradiance information to the brain, and are responsible of the non-image forming responses to light, such as circadian photoentrainment or the pupillary reflex. Thus, there are two functional RGC types, image forming and non-image forming. Image-forming RGCs do not merely relay the luminous information, they extract different aspects of the image detecting light features, and thus, different RGC subtypes are specialized in specific light features.

Because the retina is part of the central nervous system RGC degeneration leads to an irrevocable loss of function which translates into blindness and dysregulation of the circadian rhythm. Current research aims to find the whys and hows behind RGC death in different pathophysiological scenarios, including the crosstalk of RGCs with glial cells, and much effort is being devoted to discover neuroprotective and neuroregenerative therapies.

The aim of this Special Issue is to update the current knowledge on RGCs, from the developmental cues that specify them to their response to injury.

You are warmly invited to submit original research, mini and full reviews, short communications, as well as perspectives, addressing any aspect of RGC biology.

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 papers will be 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.

The retinal ganglion cells (RGC) may be considered an easily accessible pathophysiological site of degenerative processes in neurological diseases, such as the RGC damage detectable in multiple sclerosis (MS) patients with (HON) and without a history of optic neuritis (NON). We aimed to assess and interrelate RGC functional and structural damage in different retinal layers and retinal sites. We included 12 NON patients, 11 HON patients and 14 healthy controls for cross-sectional multifocal pattern electroretinography (mfPERG) and optical coherence tomography (OCT) measurements. Amplitude and peak times of the mfPERG were assessed. Macula and disc OCT scans were acquired to determine macular retinal layer and peripapillary retinal nerve fiber layer (pRNFL) thickness. In both HON and NON patients the foveal N2 amplitude of the mfPERG was reduced compared to controls. The parafoveal P1 peak time was significantly reduced in HON only. For OCT, parafoveal (pfGCL) and perifoveal (pGCL) ganglion cell layer thicknesses were decreased in HON vs. controls, while pRNFL in the papillomacular bundle sector (PMB) showed reductions in both NON and HON. As the mfPERG derived N2 originates from RGC axons, these findings suggest foveal axonal dysfunction not only in HON, but also in NON patients. Full article
