Intravitreal allogeneic mesenchymal stem cells: a non-randomized phase II clinical trial for acute non-arteritic optic neuropathy
CONCLUSIONS: Besides the development of an epiretinal membrane in one patient, the intravitreal application of allogeneic BM-MSCs appeared to be intraocularly well tolerated. Consequently, not only NA-AION but also BM-MSCs deserve more clinical investigational resources and a larger randomized multicenter trial that would provide stronger evidence both about safety and the potential therapeutic efficacy of intravitreally injected allogeneic BM-MSCs in acute NA-AION.TRIAL REGISTRATION: Safety Assessment of Intravitreal Mesenchymal Stem Cells for Acute Non-Arteritic Anterior Ischemic Optic Neuropathy (NEUROSTEM). NCT03173638...

Hyperbaric oxygen therapy suppresses hypoxia and reoxygenation injury to retinal pigment epithelial cells through activating peroxisome proliferator activator receptor-alpha signalling
J Cell Mol Med. 2023 Sep 20. doi: 10.1111/jcmm.17963. Online ahead of print.ABSTRACTRetinal ischemia followed by reperfusion (IR) is a common cause of many ocular disorders, such as age-related macular degeneration (AMD), which leads to blindness in the elderly population, and proper therapies remain unavailable. Retinal pigment epithelial (RPE) cell death is a hallmark of AMD. Hyperbaric oxygen (HBO) therapy can improve IR tissue survival by inducing ischemic preconditioning responses. We conducted an in vitro study to examine the effects of HBO preconditioning on oxygen-glucose deprivation (OGD)-induced IR-injured RPE ce...

Nationwide trends in emergency department utilisation for acute retinal ischaemia in the USA, 2011-2018
Conclusion Of the estimated 48 000 patients with TMVL or RAO annually in the USA, few are evaluated in the ED, and admission rates are less than for transient ischaemic attack or ischaemic stroke and are decreasing over time.

Serum retinol-binding protein 4 in stroke patients: correlation with T helper 17/regulatory T cell imbalance and 3-year cognitive function decline
ConclusionSerum RBP4 is positively associated with a Th17/Treg cell imbalance and, more importantly, it is indicative of cognitive function decline within 3 years in stroke patients. Thus, early and timely interventions and physical rehabilitation are more necessary in stroke patients with high serum RBP4.

A novel primary porcine retinal pigment epithelium cell model with preserved properties
CONCLUSIONS: This work describes, for the first time, a pRPE cell model that exhibits preserved RPE properties for several passages on cell culture plastic plates. Though RPE characteristics were maintained for at least 6 passages, the reduced CRALBP and RPE-65 with passaging emphasize that lower passage cells are advantageous to utilise, and that morphology, barrier function and ZO-1 localisation cannot be solely employed as a quality measure of RPE identity. Pigs are phylogenetically similar to humans, including similar physiology, anatomy and immune system. Therefore, porcine RPE cells constitute a relevant model system...

Unleashing the potential of CRISPR multiplexing: Harnessing Cas12 and Cas13 for precise gene modulation in eye diseases
Vision Res. 2023 Sep 16;213:108317. doi: 10.1016/j.visres.2023.108317. Online ahead of print.ABSTRACTGene therapy is a flourishing field with the potential to revolutionize the treatment of genetic diseases. The emergence of CRISPR-Cas9 has significantly advanced targeted and efficient genome editing. Although CRISPR-Cas9 has demonstrated promising potential applications in various genetic disorders, it faces limitations in simultaneously targeting multiple genes. Novel CRISPR systems, such as Cas12 and Cas13, have been developed to overcome these challenges, enabling multiplexing and providing unique advantages. Cas13, in...
