Decoding retinitis pigmentosa: molecular targets and therapy with focus on pre-mRNA splicing

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Retinitis pigmentosa (RP) is a leading cause of inherited blindness.
• Mutations in splicing factors are implicated in RP pathogenesis.
• The tissue-specific effect of spliceosomal component mutations on the retina remains poorly understood.

Purpose of the Study:

• To elucidate the molecular mechanisms behind the retinal-specific effects of splicing factor dysfunction in RP.
• To review current and emerging therapeutic strategies for RP.

Main Methods:

• Literature review of studies utilizing cell culture, animal models, and retinal organoids.
• Analysis of molecular mechanisms underlying splicing factor dysfunction.
• Evaluation of gene therapy, antisense oligonucleotides, and cell transplantation approaches.

Main Results:

• Splicing factor mutations can lead to retinal degeneration.
• The precise reasons for the retina's vulnerability to these mutations are being investigated.
• Various therapeutic avenues show promise in slowing RP progression.

Conclusions:

• Understanding the molecular basis of RP is crucial for developing effective treatments.
• Gene therapy, ASOs, and cell transplantation offer potential therapeutic benefits for RP.
• Further improvements are needed for successful clinical translation of these strategies.
