Type IV collagen-binding proteins of neutrophils: possible involvement of L-selectin in the neutrophil binding to type IV collagen.
To isolate type IV collagen-binding proteins, 125I-labeled human-neutrophil extracts were chromatographed on a type IV collagen-Sepharose column. The affinity chromatography-separated fraction contained the four radioactive proteins with apparent molecular masses of 28, 49, 67, and 95 kD on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Western blot analysis indicated that the 95-kD...
متن کاملBinding of laminin to type IV collagen: a morphological study
A mixture of laminin and type IV collagen was analyzed by rotary shadowing using carbon/platinum and electron microscopy. Laminin was found to form distinct complexes with type IV collagen: one site of interaction is located 140 nm from the COOH-terminal, noncollagenous (NC1) domain and the other is located within the NH2-terminal region. The isolated NC1 fragment of type IV collagen does not a...
متن کاملHuman granulosa cells express integrin alpha2 and collagen type IV: possible involvement of collagen type IV in granulosa cell luteinization.
Previously, it has been shown that integrin alpha6beta1 expressed on human granulosa cells regulates luteinization in co-operation with its ligand, laminin. In this study, integrin alpha2 was immunohistochemically demonstrated to be expressed on granulosa and large luteal cells. It was also detected on luteinizing theca interna cells after ovulation. Immunoreactive collagen type IV, which is on...
متن کاملStudy of Basement Membrane Type IV Collagen Appearance in the Brain Choroids Plexus of Mouse Fetuses
Introduction & Objective: The brain choroids plexus (BCP) plays an important role in the cerebrospinal fluid (CSF) production, but its characterization is still incomplete. Collagen type IV, is one of the most important proteins of basement membrane (BM) and extracellular matrix (ECM) of BCP. In the present study we investigated the differential period of type IV collagen in basement membrane...
متن کاملThe Role of Type IV Collagen in Developing Lens in Mouse Fetuses
Objective(s) Extracellular matrix (ECM) and basement membrane (BM) play important roles in many developmental processes during development and after birth. Among the components of the BM, collagen fibers specially type IV are the most important parts. The aim of this study was to determine the time when collagen type IV appears in the BM of lens structure during mouse embryonic development. M...
