The Ultrastructural Localization of Type II, IV, and VI Collagens at the Vitreoretinal Interface. [PDF]

PLoS ONE, 2015
The vitreoretinal interface is the border of the cortical vitreous and the inner surface of the retina. The adhesion of the cortical vitreous to the ILM, namely vitreoretinal adhesion, involves a series of complex molecular adhesion mechanisms and has ...

Application of Collagen I and IV in Bioengineering Transparent Ocular Tissues

Frontiers in Surgery, 2021
Collagens represent a major group of structural proteins expressed in different tissues and display distinct and variable properties. Whilst collagens are non-transparent in the skin, they confer transparency in the cornea and crystalline lens of the eye.

Utilization of commercial collagens for preparing well-differentiated human beta cells for confocal microscopy

Frontiers in Endocrinology, 2023
IntroductionWith technical advances, confocal and super-resolution microscopy have become powerful tools to dissect cellular pathophysiology. Cell attachment to glass surfaces compatible with advanced imaging is critical prerequisite but remains a ...

Cross-linking in type IV collagen [PDF]

Biochemical Journal, 1984
Type IV collagen could not be extracted from human placenta using 6M-urea containing 10mM-dithiothreitol, indicating that the type IV molecule is stabilized within the basement membrane by covalent cross-links. However, various forms of type IV collagen molecule were extractable by means of increasingly severe proteolytic conditions.

Porphyromonas gingivalis Induced Fragmentation of Type IV Collagen Through Macrophage-Activated MMP-9: (In Vitro Study of Collagenolytic Mechanism in Pathogenesis of Atherosclerotic Plaque Rupture)

Indonesian Biomedical Journal, 2009
BACKGROUND: Periodontitis is caused mostly by Porphyromonas gingivalis (P.gingivalis) and it is related to acute coronary syndrome. P.gingivalis  readily invades blood circulation and potentially induces collagenolytic activity of inflammatory cells that
