The increased transport of fluorescent malignant cell-derived exosomes through an intact HUVEC monolayer may suggest that the reduced stiffness allows for increased paracellular transport, such as reduced rigidity contributing to transport across biological membranes in the paracellular transport of leukocytes across the endothelia 33 and the increased transdermal transport of ultraflexible liposomes 34. Exosome-mediated complement activation moden onani skog a typical human serum. Sexy tispe sex sex kontakter. Cancer nanomedicine and the complement system activation paradigm: In conclusion, this work demonstrates differences in mechanical and complement activation properties of malignant and non-malignant cell-derived exosomes that may contribute to increased endothelial disruption as well as tumour growth. The observed decreases in TEER of HUVEC monolayers allied with no decrease in cell viability, when treated with malignant cell-derived exosomes, suggests that the monolayer is disrupted at the junction level or through cellular retraction. Stimulation causes the sequential activation of the complement protein cascade, ultimately resulting in deposition of the membrane attack complex to lyse invading pathogens in addition to complementing the adaptive immune response through immune cell recruitment and microbial opsonization.
