Interferon-gamma is a T cell secreted cytokine. It has a great number of biological activities, among which is the down regulation of collagen molecules. IFN-gamma acts through cell surface receptors, but also binds to heparan sulfate proteoglycans. In vivo, it is postulated that the heparan sulfate/IFN-gamma interaction can modulate the activity and availability of the cytokine.

UI	MeSH Term	Description	Entries
D007371	Interferon-gamma	The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D005109	Extracellular Matrix	A meshwork-like substance found within the extracellular space and in association with the basement membrane of the cell surface. It promotes cellular proliferation and provides a supporting structure to which cells or cell lysates in culture dishes adhere.	Matrix, Extracellular,Extracellular Matrices,Matrices, Extracellular
D005355	Fibrosis	Any pathological condition where fibrous connective tissue invades any organ, usually as a consequence of inflammation or other injury.	Cirrhosis,Fibroses
D006497	Heparitin Sulfate	A heteropolysaccharide that is similar in structure to HEPARIN. It accumulates in individuals with MUCOPOLYSACCHARIDOSIS.	Heparan Sulfate,Sulfate, Heparan,Sulfate, Heparitin

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
