Summary
Insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) have dual roles in eye diseases. Understanding their balance is key to managing retinopathies.
Area of Science:
- Ophthalmology
- Endocrinology
- Molecular Biology
Background:
- Insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) play complex roles in ocular health and disease.
- IGFBP-3 is implicated in vascular protection and anti-inflammatory responses.
- IGFBP-5 has been linked to both fibrosis and reduced neovascularization in the eye.
Purpose of the Study:
- To review recent findings on IGF and IGFBP expression in the eye.
- To discuss the relevance of these factors in various retinopathies.
Main Methods:
- Literature review of studies on IGF and IGFBP expression.
- Analysis of their roles in retinal layers and vitreous.
- Examination of their impact on ocular disease models.
Main Results:
- IGFBP-3 promotes vascular progenitor cell activity and has anti-inflammatory effects.
- IGFBP-5 is associated with fibrosis and neovascularization modulation.
- The balance between IGFs and IGFBPs significantly impacts ocular tissues.
Conclusions:
- The differential expression and function of IGFBPs are critical in the pathogenesis of retinopathies.
- Targeting the IGF/IGFBP axis may offer therapeutic strategies for eye diseases.

01:16TGF - β Signaling Pathway
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
