Oral administration of Tremella fuciformis polysaccharides may constitute a new, effective therapy for Atopic dermatitis, improving both immune response and intestinal microbiota.
Experimental Study Eczema Gut Microbiota Polysaccharides
In the methodology of this study, the therapeutic effects of Tremella fuciformis polysaccharides (these have multiple biological activities), on Atopic dermatitis, were examined through both topical application and oral administration on mice induced with Atopic dermatitis-like disorder. The changes across transdermal water loss, epidermal thickening, and ear edema in the affected mice were observed. Notably, the study also considered the polysaccharides' impacts on the proportion of specific regulatory T cells in the mesenteric lymph nodes of the mice.
The results showed that both therapeutic methods positively impacted the conditions of the affected mice, with oral administration offering superior efficacy over topical application. The oral administration of the polysaccharides led to an increase of specific regulatory T cells, evidence of immune regulation. Further, non-targeted metabolomics and sequencing of certain DNA amplicons pointed towards observable modulation in fecal metabolites and a changed composition of gut microbiota in the mice following the oral treatment.
