Lichen-Derived Polysaccharide from Cladina rangiferina Alleviates UVB-Induced Skin Photoaging: Potential Role of the NRF2-Mediated Antioxidant Response
In a previous study, we isolated a water-soluble heteropolysaccharide (CRWP-S) from the edible lichen Cladina rangiferina (L.) Nyl., which exhibited potent free radical-scavenging capacities. However, its protective efficacy against ultraviolet B (UVB)-induced skin photoaging and the underlying molecular mechanisms rem...
