Fig. 2From: Bacteria associated with acne use glycosaminoglycans as cell adhesion receptors and promote changes in the expression of the genes involved in their biosynthesisEffect of enzymatic degradation of cell GAGs on bacterial adherence to skin cells. Inhibition of bacterial attachment to (a) keratinocytes and (b) fibroblasts treated with heparinases I and III (grey bars) or chondroitinase ABC (white bars). Data were normalized using the adhesion values of bacteria to non-treated cells, which was given the arbitrary value of 1. The spreads represent the standard deviationsBack to article page
