Fig. 3From: Bacteria associated with acne use glycosaminoglycans as cell adhesion receptors and promote changes in the expression of the genes involved in their biosynthesisInhibition of bacterial attachment to skin cells in the presence of different GAGs. Adhesion of Propinebacterium acnes (a, b), Staphyloccocus aureus (c,d), Staphyloccocus epidermidis (e,f) to keratinocytes and fibroblasts in the presence of different concentrations of HS (●), a mixture of CS (□) and a mixture of all GAGs (Δ). Data were normalized using the adhesion values of bacteria to non-treated cells, which was given the arbitrary value of 1Back to article page
