Lipid-Based Nanovectors for Targeting of CD44-Overexpressing Tumor Cells

الملخص EN

Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan that exists in living systems, and it is a major component of the extracellular matrix.

The hyaluronic acid receptor CD44 is found at low levels on the surface of epithelial, haematopoietic, and neuronal cells and is overexpressed in many cancer cells particularly in tumour initiating cells.

HA has been therefore used as ligand attached to HA-lipid-based nanovectors for the active targeting of small or large active molecules for the treatment of cancer.

This paper describes the different approaches employed for the preparation, characterization, and evaluation of these potent delivery systems.
