Abstract

<p>(I) CTO reverts the effects of CML exosome treatment on VCAM1, ICAM1 and IL8 mRNA expression in HUVEC cells. VCAM1 (a), ICAM1(b) and IL8 (c) mRNA expression increased in a dose dependent manner after adding exosomes (Exo) to endothelial cell monolayer. CTO (1-5-10 µM) reverts these effects in a time- and dose dependent manner. (II) VCAM1, ICAM1 and IL8 mRNA expression in HUVEC treated for 6 h either with low serum medium (CN), or with 50 µg/ml exosomes (Exo), or with 10 ng/ml of recombinant IL8 (Rec IL8) with or without CTO 10 µM, or with 50 µg/ml exosomes plus 10 µg/ml of a neutralizing anti-IL8 antibody (N Ab IL8). Values are representative for three independent experiments. *p≤0.05; **p≤0.01.</p
