Mesangial cells and their adhesive properties

Exp Nephrol. 1999 Mar-Apr;7(2):137-46. doi: 10.1159/000020594.


Glomerular mesangial cells play a central role in maintaining structure and function of the glomerular capillary ultrafiltration apparatus. Under physiological and pathological conditions, mesangial cells regulate amount and composition of the surrounding extracellular matrix. Conversely, components of the embedding matrix affect the mesangial cell phenotype. These interactions are mediated via specific cell surface receptors, the best studied group of which is the beta1 integrin family. The beta1 integrins play a role in mesangial cell adhesion, migration, survival and proliferation. Expression and abundance of integrins in healthy and diseased glomeruli and their functions and mediation of signals are discussed in this review. Other factors modulating mesangial cell-matrix interactions, such as antiadhesive proteins, cytokines, disintegrins and nitric oxide, are also considered. The available evidence from in vitro and in vivo studies indicates that receptor-mediated interactions between mesangial cells and the normal or abnormal extracellular matrix regulate the mesangial cell phenotype and thus contribute to normal maintenance of the glomerulus and to remodeling and repair of the glomerular capillary tuft in response to injury.
