ICAM1 and serum lipopolysaccharide activity: In 2019, Jongman et al. measured mRNA of adhesion molecules ICAM‐1, VCAM‐1, and E‐selectin in pulmonary, cardiac, renal, and hepatic ECs, at baseline and following hemorrhagic shock or endotoxemia in WT versus Tie‐2 deficient mice (Jongman et al., 2019).
