Inflammatory reactions are common in daily life, and an important feature of inflammatory reactions is the outflow of white blood cells. Leukocyte outflow is an important process of leukocyte transfer to the site of inflammation, and leukocyte outflow is inseparable from the natural ligand sLex on leukocytes and the surface of endothelial cells due to inflammatory factors induced by the combination of E-selectin, although the two will combine, but Their affinity is not high, so this topic proposes modification and improvement on sLex to achieve an improvement in the affinity between the two.

Inflammatory response is very common in daily life, and the important characteristic of inflammatory response is leukocyte outflow. Leukocyte efflux is an important process of leukocyte transfer to the inflammatory site, and leukocyte efflux is inseparable from the combination of SELEX, a natural ligand on leukocyte, and E-selectin induced by inflammatory factors on the surface of endothelial cells. Although they can combine, their affinity is not high. Therefore, this paper proposes modification and improvement of SELEX to improve the affinity between them.<br>
