Abstract

Collagen is one of the most abundant proteins in human tissues. Together with other connective tissue components (non-collagenous glycoproteins, proteoglycans, laminins, thrombospondins, entactin and tenascin), collagen promotes cellular adhesion, activates intracellular signals, and regulates the biological activities of growth factors and other proteins. During the past 20 years at least 19 genetically different collagenous proteins coded by 30 distinct genes have been identified. Here, we review some new aspects of the collagens that form fibrils, sheets, or beaded filaments, and of the so-called multiplexin collagens. Whenever possible, we give insights regarding the association of the structural abnormalities of these proteins as they relate with human disease(s).

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
