AI Article Synopsis

  • X-linked retinitis pigmentosa (XLRP) is a hereditary eye disease leading to vision loss due to issues with photoreceptors, primarily caused by mutations in the RPGR gene.
  • Researchers studied retinal organoids derived from both normal and RPGR-mutant human cells over four developmental stages using advanced single-cell RNA sequencing.
  • The findings offer a valuable data resource for understanding RPGR-related retinal degeneration and could help in developing targeted therapies for this condition.

Article Abstract

X-linked retinitis pigmentosa (XLRP) is a severe hereditary retinal disorder marked by progressive vision loss due to photoreceptor dysfunction. The retinitis pigmentosa GTPase regulator (RPGR) gene, responsible for most XLRP cases, encodes a protein crucial for the transport of visual signal proteins between the photoreceptor inner and outer segments. However, the mechanism of RPGR mutation causing photoreceptor disorder is not clear and effective treatments remain elusive. This study utilized retinal organoids (ROs) derived from normal and RPGR-mutant human induced pluripotent stem cells (hiPSC) at four developmental stages (40, 90, 150, and 200 days). Single-cell RNA sequencing (scRNA-seq) was conducted on 71,096 cells, including 33,839 cells from the control group and 37,257 cells from the RPGR group. Key retinal cell types were identified and the obtained scRNAseq dataset was validated reliable and high -quality. This study has provided data resources and references for exploring the mechanism of RPGR-related retinal degeneration and support the development of targeted therapies.

Mutations in the PRPF31 gene are a well-known cause of autosomal dominant retinitis pigmentosa (RP), the most prevalent genetic form of blindness in adults, affecting 1 in 4,000 individuals globally. In this study, peripheral blood mononuclear cells from a patient carrying a heterozygous mutation in PRPF31 were reprogrammed to generate the human iPSC line ESi132-A. This cell line was thoroughly characterized for self-renewal and pluripotency.

Purpose: This study aimed to identify a novel recombinant adeno-associated virus (rAAV) capsid variant that can widely transfect the deep retina through intravitreal injection and to assess their effectiveness and safety in gene delivery.

Methods: By adopting the sequences of various cell-penetrating peptides and inserting them into the capsid modification region of AAV2, we generated several novel variants. The green fluorescent protein (GFP)-carrying variants were screened following intravitreal injection.

Retinitis pigmentosa (RP) is a group of inherited retinal diseases characterized by progressive loss of photoreceptor cells and retinal pigment epithelium function. Its treatment has long been a focus and challenge in ophthalmic research. Despite advances in therapies such as stem cell transplantation, gene therapy, and retinal prosthetic implants, many difficulties remain.

Retinitis Pigmentosa type 25 (RP25) is a form of inherited retinal dystrophy characterized by a progressive loss of rod photoreceptors, subsequent degeneration of cone photoreceptors, and eventually, the retinal pigment epithelium. Caused by mutations in the EYS gene, it is believed to be critical for the structural and functional integrity of the retina. Using a non-integrative RNA reprogramming method, we have generated human induced pluripotent stem cell (hiPSC) lines from RP25 patient and from carriers but asymptomatic daughters.
