MMP-1, or Matrix Metalloproteinase-1, is an enzyme that plays a crucial role in the breakdown of extracellular matrix components, particularly collagen. It is produced by various cell types, including fibroblasts and macrophages, and is involved in normal tissue remodeling and repair processes. In addition to its role in healthy tissue maintenance, MMP-1 is also implicated in various pathological conditions, such as arthritis and cancer. Elevated levels of this enzyme can contribute to tissue degradation and inflammation, making it a potential target for therapeutic interventions in diseases characterized by excessive matrix breakdown.
