SIRTUIN INDUCER, TISSUE REPAIRING AGENT, HEPATOCYTE GROWTH FACTOR INDUCER, TISSUE HOMEOSTASIS MAINTENANCE AGENT, AND TLR4 AGONIST, HAVING HYALURONIC ACID FRAGMENT AS ACTIVE INGREDIENT

摘要

Provided are a TLR4 agent, a tissue homeostasis agent, a hepatocyte growth factor inducer, a tissue repairing agent, and a sirtuin inducer using hyaluronic acid fragments. Hyaluronic acid fragments selected from sizes of 2-20 sugar units, inclusive, or a pharmaceutically acceptable salt or solvate thereof, are used as the active ingredients of a TLR4 agent, a tissue homeostasis agent, a hepatocyte growth factor inducer, a tissue repairing agent, and a sirtuin inducer. The hyaluronic acid fragments are preferably hyaluronic acid fragments selected from sizes of 3-10 sugar units, inclusive, and more preferably are hyaluronic acid fragments of 3 or 4 sugar units.
