Abstract:Previous studies suggest an association of cardiac microvascular endothelial cells (CMECs) hyperpermeability with sepsis-related cardiac injury. Our results showed that CMECs permeability was dependent upon concentration and time of lipopolysaccharides (LPS) stimulation. Integrin ανβ3 expression decreased after LPS stimulation. Pretreatment with anti-integrin ανβ3 antibody enhanced LPS-induced hyperpermeability. Upregulation of integrin ανβ3 decreased LPS-induced hyperpermeability. F-actin remodeling was enhan… Show more
