Inhibition of cell-cell binding by lipid assemblies
First Claim
Patent Images
1. A lipid assembly for inhibiting the binding between a first cell having a receptor and a second cell having a ligand for said receptor, comprising one or more lipid assemblies, wherein said one or more lipid assemblies comprise:
- a) lipid monomers, wherein 25-95% of said lipid monomers are unpolymerized;
b) 5-50% surface exposed negatively charged oxyacid groups present on said lipid monomers of said lipid assemblies, wherein said surface exposed negatively charged oxyacid groups meet the anionic binding requirement of said receptor; and
c) 5-20% surface exposed carbohydrates which selectively bind to said receptor.

Abstract
This invention relates generally to the field of therapeutic compounds designed to interfere between the binding of ligands and their receptors on cell surface. More specifically, it provides products and methods for inhibiting cell migration and activation using lipid assemblies with surface recognition elements that are specific for the receptors involved in cell migration and activation.
