Abstract
Novel methods and compositions are provided for modulating homing of leukocytes, particularly lymphocytes, where the compounds are cross-reactive with Neu5Ac2-3Galβ1−X[Fucα1−y]GlcNAc, where one of x and y is three and the other is four. These compounds may be administered to a host associated with inflammation, to avoid the deleterious effects of leukocyte infiltration.
Claims3
A method for modulating the binding of leukocytes to endothelial cells expressing ELAM-1, said method comprising:
- adding to a combination of cells comprising leukocytes and endothelial cells expressing ELAM-1, in an amount sufficient to modulate the binding of leukocytes to said ELAM-1, a glycoconjugate of sialyl-Lea or derivative thereof.
A method for inhibiting infiltration of leukocytes into an inflammation site of a host, said method comprising:
- administering to said host in an amount sufficient to inhibit leukocyte infiltration, a glycoconjugate of sialyl-Lea or derivative thereof.
A method for inhibiting infiltration of lymphocytes into an inflammation site of a host, said method comprising:
- administering to said host in an amount sufficient to inhibit lymphocyte infiltration, a glycoconjugate of sialyl-Lea or derivative thereof.
