Role of CD147 (EMMPRIN/Basigin) in Tissue Remodeling

CD147, also known as extracellular matrix metalloproteinase inducer (EMMPRIN) or basigin, is expressed in a variety of cell types. It is involved in the regulation of extracellular matrix (ECM) remodeling during physiological and pathological processes including wound healing, inflammatory diseases, and cancer. CD147 is a diagnostic and therapeutic target in cancer and inflammatory diseases, either directly or indirectly, by targeting CD147 partners. It can trigger matrix metalloproteinase inductions involved in ECM degradation, cell adhesion, and cell-cell interactions. It can also induce myofibroblast differentiation associated with ECM deposition and contraction. The shift from fibrosis to lysis, and vice versa, is poorly understood and could involve CD147. This article provides an overview of the role of CD147 in the regulation of ECM remodeling processes and discusses the involvement of the microenvironment in the modulation of its downstream effects. Understanding CD147 regulation could help identify new therapeutic intervention. Anat Rec, 2019. © 2019 Wiley Periodicals, Inc.
