背景信息

Retinal pigment epithelium (RPE) recombinant proteins are engineered molecules designed to mimic or supplement the natural functions of the RPE, a critical layer of cells in the eye that supports photoreceptor health. The RPE plays essential roles in visual cycle metabolism, nutrient transport, waste clearance, and protection against oxidative stress. Dysfunction or degeneration of RPE cells is implicated in retinal diseases such as age-related macular degeneration (AMD), Stargardt disease, and retinitis pigmentosa, which collectively represent leading causes of irreversible vision loss.

Traditional therapeutic approaches for these conditions have been limited, prompting research into recombinant protein technologies. RPE recombinant proteins are typically produced using biotechnological platforms (e.g., mammalian, insect, or bacterial expression systems) to express and purify proteins like complement inhibitors, growth factors, or enzymes crucial for retinal homeostasis. For example, recombinant human proteins such as CFH (complement factor H) or PEDF (pigment epithelium-derived factor) have been explored to modulate inflammation or angiogenesis in AMD.

Advances in genetic engineering and structural biology have enabled the design of modified recombinant proteins with enhanced stability, bioavailability, or tissue targeting. Some strategies fuse RPE-specific proteins with Fc domains or cell-penetrating peptides to improve ocular penetration and prolong therapeutic effects. Additionally, recombinant proteins are being investigated as components of cell-based therapies, where engineered RPE cells derived from stem cells secrete therapeutic proteins to rescue photoreceptors.

Challenges remain in optimizing protein delivery to the subretinal space, minimizing immune responses, and ensuring long-term efficacy. However, preclinical studies and early-phase clinical trials have shown promise, particularly in slowing disease progression. As molecular understanding of RPE-pathology interactions deepens, recombinant proteins are poised to play a transformative role in treating previously untreatable retinal disorders, either as standalone therapies or in combination with gene editing, cell transplantation, or biomaterial-based delivery systems.
