1994) proposed that the mechanism of absorption enhancement was a combination of mucoadhesion and a loosening effect on the tension of the tight junctions through ionic interactions with negatively charged groups of glycocalix.
15,16) We examined the cyst lining from a patient from our institution by electron microscopy and detected many microvilli decorated with glycocalix (Figure 4) but no true cilia, which is in keeping with the newer literature.
However, the strong electrostatic interaction between the positively charged particles and the negatively charged glycocalix may slow down the progression and penetration of these particles towards the epithelial cell surface reducing their uptake.
