Inhibition of UV-induced immune suppression and interleukin-10 production by cytoprotective tamarind oligosaccharides

摘要

Methods and compositions are disclosed for the prevention and/or treatment of immunological damage to skin exposed to ultraviolet irradiation. The compositions described herein include biologically active tamarind seed xyloglucan oligosaccharides obtained via treatment of tamarind xyloglucan with a fungal beta-glucanase. Advantageously, the cytoprotective tamarind seed xyloglucan oligosaccharides are stable at ambient conditions. In one aspect, the composition includes an aqueous solution of tamarind seed xyloglucan oligosaccharides having a concentration of at least 10-6 mug per mL of the solution. In another aspect, the method includes preventing the suppression of delayed type hypersensitivity. In yet another aspect, the invention includes reducing the amount of interleukin-10 produced by keratinocytes in the skin.
