Paracellular transport across the tight junction can occur via the pore pathway or the leak pathway, which have distinct size-selectivity and charge-selectivity and are differentially regulated by immune signalling

These effects have been recently associated with several molecular pathways [10,11,20,58,59,60,61,62,63,64,65,66], in particular with the increased expression and internalization of VEGFR2, and the activation of the VEGFR2-Akt-eNOS signaling pathway [60,61], interacting particularly with the NO [49] and prostaglandins systems [50]
