Regarding the proteins involved in carbohydrate metabolism that were uniquely expressed in the samples from the atopic dermatitis group, very promisingly we identified triosephosphate isomerase (TPI) (PEL of 15.73, EC: 5.3.1.1) in Alloscardovia omnicolens F0580 from Bifidobacteriaceae. This evidence concerns the gene TPI1 and atopic eczema.
