Abstract
β-glucans are derived from a variety of sources including yeast, grain and fungus and belong to the class of drugs known as biological response modifiers. They possess a broad spectrum of biological activities that enhance immunity in humans. One promising area for β-glucans' application is dermatology, including wound care. Topical applications of β-glucans are increasing, especially due to their pluripotent properties. Macrophages, keratinocytes and fibroblasts are considered the main target cells of β-glucans during wound healing. β-glucans enhance wound repair by increasing the infiltration of macrophages, which stimulates tissue granulation, collagen deposition and reepithelialization. β-glucan wound dressings represent a suitable wound healing agent, with great stability and resistance to wound proteases. This review summarizes the current knowledge and progress made on characterizing β-glucans' wound healing properties in vitro and in vivo and their safety and efficacy in managing non-healing wounds or other chronic dermatological conditions and diseases.
