Adrenoceptor stimulation does not affect ICAM-1 and VCAM-1 expression in vitro.

Background: Endothelial adhesion molecules ICAM-1 (CD54) and VCAM-1 (CD106) mediate cellular adhesion and transcellular migration. Cell adhesion and diapedesis have a key role in the course of shock and sepsis. During severe sepsis, adrenoceptor agonist levels may be increased due to endogenous production or due to intensive care treatment.
