Vesilute
Also known as: Lys-Glu-Asp-Leu, Khavinson eye peptide, Retinal bioregulator, Vision bioregulator
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.
Half-Life
Short (minutes); sustained gene-regulatory effects
Route
SubQ, Oral
Category
Anti-Aging & Longevity
Key Benefits
- Supports retinal photoreceptor cell function and survival
- May slow progression of age-related macular degeneration
- Reduces retinal cell apoptosis from oxidative stress and aging
- Anti-aging effects on retinal pigment epithelium
- Potential support in diabetic retinopathy management
- Preserves visual acuity with aging
- Complementary to lutein, zeaxanthin, and NAD+ in ocular health protocols
Mechanism of Action
Vesilute's tetrapeptide Lys-Glu-Asp-Leu modulates gene expression in retinal pigment epithelial cells and photoreceptors. By interacting with chromatin in retinal tissue, it normalizes protein synthesis essential for phototransduction, reduces retinal cell apoptosis, and may slow the accumulation of drusen and lipofuscin associated with AMD. Its sequence is homologous to retinal tissue proteins, conferring tissue specificity.
