    Summary

    Injection of endogenous immunopeptides into rabbit eyes induced lymphoid inflammation and new blood vessel formation. The L fraction showed more localized effects, suggesting potential for treating vitreoretinal proliferation.

    Area of Science:

    • Ophthalmology
    • Immunology
    • Regenerative Medicine

    Context:

    • Vitreoretinal proliferation is a significant cause of vision loss.
    • Current treatments for vitreoretinal proliferation have limitations.
    • Understanding the role of endogenous immunopeptides in ocular inflammation is crucial.

    Purpose:

    • To investigate the effects of endogenous immunopeptides on vitreous body.
    • To evaluate the potential of these immunopeptides in modeling vitreoretinal proliferation.

    Summary:

    • Autologous peripheral blood lymphocyte-derived immunopeptides (L fraction: 40-60 kDa; M fraction: 15-30 kDa) were injected into rabbit vitreous.
    • Both fractions induced lymphoid inflammatory infiltration and neovascularization.
    • The L fraction specifically triggered localized exudative processes with fibroplastic cord formation, a key proliferative component.
