IRBP (1-20) (human, rat) TFA

SKU: orb1980120

Description

Interphotoreceptor retinoid-binding protein (1-20) (IRBP1-20), a dodecapeptide fragment of retinoid-binding protein 3, plays a crucial role in pigment regeneration by facilitating the transport of retinol and retinal between photoreceptor cells and the retinal pigment epithelium. It has been utilized to provoke autoimmune uveoretinitis in C57BL/6 mice, possessing the H-2b haplotype. Furthermore, IRBP1-20 at a concentration of 3 µM enhances the secretion of IL-4, IL-5, and IL-6 from primary mouse spleen lymphocytes. Immunization and subsequent rechallenge with IRBP1-20 lead to increased ear swelling, inflammation of ocular blood vessels, infiltration by immune cells, damage to the photoreceptor layer, and retinal detachment in IFN-γ-deficient mice.
