Abstract
Wound healing is a highly regulated process starting from coagulation and ending in tissue remodeling. The end result varies from perfectly restored tissue, such as in early fetal skin, to scars in adults. The balanced repair process is frequently disturbed by local or systemic factors, like infections and diabetes. A rapid increase of hyaluronan is an inherent feature of wounds and is associated with tissue swelling, epithelial and mesenchymal cell migration and proliferation, and induction of cytokine signaling. Hyaluronan extending from cell surface into structures called cables can trap leukocytes and platelets and change their functions. All these features of hyaluronan modulate inflammation. The present data show that mannose, a recently described inhibitor of hyaluronan synthesis, inhibits dermal fibroblast invasion and prevents the enhanced leukocyte binding to hyaluronan that takes place in cells treated with an inflammatory mediator interleukin-1 beta. Mannose also reduced hyaluronan in subcutaneous sponge granulation tissue, a model of skin wound, and suppressed its leukocyte recruitment and tissue growth. Mannose thus seems to suppress wounding-induced inflammation in skin by attenuating hyaluronan synthesis.
