Antibodies to beta-4 integrin have been identified in generalized MMP and ocular MMP, and antibodies to alpha-6 integrin have been identified in oral MMP. (msdmanuals.com)

The Goodpasture epitopes are structurally sequestered by the adjacent alpha-4(IV)NC1 and alpha-5(IV)NC1 molecules. (medscape.com)

Two collagen IV protomers associate through the carboxy-terminal NC1 trimer to form the NC1 hexamer. (wikipedia.org)
Several forms of collagen type V exist depending upon the composition of the subunits that form the trimer. (lookformedical.com)

These interactions form the core of the type IV collagen scaffold. (wikipedia.org)
Using these two types of interactions, type IV collagen forms an extended network, shown here in light blue. (rcsb.org)
However, most studies on cancer invasion utilize 3D collagen matrices, thereby ignoring the importance of HA-CD44 interactions. (bvsalud.org)
These types of interactions would be expected for all routes of exposure. (cdc.gov)

High voltage electron microscopy demonstrated that culture cell layers were three to four cells thick. (silverchair.com)
