Hyaluronan (HA) has viscoelastic, anti-inflammatory and protective actions in joint tissues, and is being widely used for treatment of OA and RA patients. However, the mechanisms underlying the pharmacological action of HA on OA and RA have not been fully understood. In this article, we review the molecular weight-dependent, anti-inflammatory actions of HA preparations - produced in Japan - in joint tissues, and show that the molecular weight of HA, but not its concentration, is crucial for maintenance of cartilage elasticity.
