Summary: This study investigated the activation of microglia and its contribution to photoreceptor degeneration in retinitis pigmentosa (RP). The results showed that disease-associated microglia activation can suppress the degeneration of rods and cones, reducing secondary damage caused by the accumulation of dead cells and infiltrated neutrophils.

Summary: As individuals age, dysfunctional microglia may contribute to the onset of neurodegenerative diseases through impaired phagocytosis, cholesterol efflux, and enhanced secretion of pro-inflammatory cytokines. Specifically, microglia lacking lipoprotein lipase exhibit a pro-inflammatory lipid profile, increased cholesterol ester content, and reduced cholesterol efflux, leading to excessive accumulation of lipid droplets. Activation of PPAR pathways by agonists can rescue this phenotype, suggesting a potential therapeutic strategy for aging and neurodegenerative diseases.

Summary: This study identified pathogenic variants in the TLCD3B gene in four patients with cone-rod dystrophy or maculopathy from three families. Knockout mice lacking Tlcd3b exhibited similar phenotypes as the patients, including reduced cone photoreceptor light responses and degeneration of cone photoreceptors. These results establish a link between loss-of-function variants in a ceramide synthase gene and human retinal dystrophy.

Summary: This study found that a nonfunctional Fas receptor has a protective effect in two different mouse models of retinal degeneration, suggesting that the retina's response to different stressors appears to be shared and driven by Fas. Reducing Fas activity might represent a potential mutation-independent therapeutic approach to preserve retinal structure and function in patients with IRD.

Summary: In this study, researchers used CRISPR/Cas9 genome editing technology to generate a mouse model with CSF1R gene haploinsufficiency, to investigate the pathogenic mechanism of adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) and the therapeutic effects of minocycline. The study found that CSF1R deficiency leads to aberrant microglial activation, and minocycline can suppress this activation and improve behavioral and pathological defects.

Summary: This study aimed to examine the intraocular tolerability of cetuximab when applied intravitreally, and its effect on axial elongation. The results showed that intravitreal injections of cetuximab could reduce axial elongation in a dose-dependent and number of treatment-dependent manner, without causing intraocular toxic effects.

Summary: Aniridia is a panocular condition characterized by the loss of iris, caused mainly by mutations in the PAX6 gene. This study assessed the effects of Pax6-haploinsufficiency on retinal morphology and vision in Pax6Sey mice. The results showed elevated intraocular pressure and declining visual acuity in Pax6Sey mice, along with local retinal damage and a possible neuroinflammatory response.

Summary: The sodium iodate (NaIO3) model is a valuable tool in studying dry AMD and evaluating the retinal structure. Through extensive research, it has been found that the death of RPE cells caused by NaIO3 injection is closely related to vision loss in patients with dry AMD. Therefore, studying NaIO3 can provide insights into the mechanisms of RPE and photoreceptor cell death and contribute to understanding RPE degeneration in AMD.

Summary: We present a new experimental model for inducing retinal ganglion cell (RGC) dysfunction and degeneration in mice. This model allows for the reliable induction of RGC dysfunction and loss, with the resilience of the optic nerve being dependent on the age of the animal. The time-defined nature of the functional and structural changes observed in this model will facilitate the study of glial responses and the evaluation of neuroprotective treatments after intraocular pressure (IOP) injury.
