Carbohydrate-functionalized nanoparticles and uses thereof
The present disclosure relates to carbohydrate-functionalized nanoparticles and methods of treating cardiovascular disease (for example, atherosclerosis).
1. A method of treating atherosclerosis, comprising;
administering to a subject in need thereof a nanoparticle comprising:
a polyamidoamine (PAMAM) dendrimer;
a carbohydrate moiety, wherein the carbohydrate moiety is mannose or galactose, wherein the carbohydrate moiety is linked to the polyamidoamine (PAMAM) dendrimer via a polyethylene glycol (PEG) linker, and wherein the PEG linker comprises at least four individual PEG units; and
an intracellular cholesteryl ester modulator to enhance removal of unesterified or free cholesterol and thereby treat atherosclerosis, and
wherein the intracellular cholesteryl ester modulator is linked to the PAMAM dendrimer on the surface of the nanoparticle.
2. The method of claim 1 , wherein the PEG linker comprises PEG with a molecular weight of about 3.5 kDa.
3. The method of claim 1 , wherein the intracellular cholesteryl ester modulator is a liver-x-receptor (LXR) agonist.
4. The method of claim 3 , wherein the LXR agonist is T0901317 or GW3965.
