Targeting of piperine intercalated in mannose-coated liposomes in experimental leishmaniasis.

Drug delivery system: targeting of pentamidines to specific sites using sugar grafted liposomes.

Different sugar-grafted liposomes were prepared and tested against experimental leishmaniasis in vivo using the classical drug pentamidine isethionate and its methoxy derivative. Both the drugs, when encapsulated in sugar-grafted liposomes were found to be more potent in comparison to normal liposome-encapsulated drug or to the free drug. Moreover, the mannose-grafted liposomes were adjudged to...

Part Ii/iii: Investigations on Alternate Approach to Target Mannose Receptors on Macrophages Using 4-sulfated N-acetyl Galactosamine More Efficiently as Compared to Mannose Decorated Liposomes, Especially for the Conditions of Leishmaniasis

Novel method of greatly enhanced delivery of liposomes to lymph nodes.

Intravenously administered liposomes are versatile carriers for drugs, contrast agents, biologics, and DNA. Liposomes and other colloidal particles are currently under investigation as lymph node delivery vehicles. After s.c. injection, conventional liposomes move into the lymphatic vessels, but are poorly retained in each draining lymph node (<2% injected dose). In this report, we describe a n...

Incorporation of mannose 6-phosphate receptors into liposomes. Receptor topography and binding of alpha-mannosidase.

A receptor that binds the lysosomal enzyme alpha-mannosidase via mannose 6-phosphate moieties (mannose 6-phosphate receptor) was purified from Swarm-rat chondrosarcoma and bovine liver microsomal membranes. Receptor-reconstituted liposomes were prepared by dialysis of taurodeoxycholate-dispersed lipids with purified mannose 6-phosphate receptor. Liposomes appeared by electron microscopy as 60-1...

Cytokine Profile of Leishmania Infantum Fucose-Mannose Ligand in Vaccinated Dogs in the Northwest of Iran

Background: Canine visceral leishmaniasis (CVL) caused by Leishmania infantum is endemic in the northwest and south of Iran. An appropriate vaccine can help to prevent and control visceral leishmaniasis in both humans and animals. Few studies have confirmed that the fucose-mannose ligand (FML) antigen of Leishmania donovani produced protective immunity in dogs against CVL. Objective: To evaluat...
