title: Folate receptor targeted liposomes encapsulating anti-cancer drugs.
abstract: Among all available lipid based nanoparticulate systems, the success of liposomal drug delivery system is evident by the number of liposomal products available in the market or under advanced stages of preclinical and clinical trials. Liposome has the ability to deliver chemotherapeutic agents to the targeted tissues or even inside the cancerous cells by enhanced intracellular penetration or improved tumour targeting. In the last decade, folate receptor mediated tumour targeting has emerged as an attractive alternative method of active targeting of cancer cells through liposomes due to its numerous advantages over other targeting methods. Folate receptors, also known as folate binding proteins, allow the binding and internalization of folate or folic acid into the cells by a method called folate receptor mediated endocytosis. They have restricted presence in normal cells and are mostly expressed during malignant transformation. In this review article, folate receptor targeting capability of liposomes has been described. This review article has focussed on the different cancer drugs which have been encapsulated in folate receptor targeted liposomes and their in vitro as well as in vivo efficacies in several tumour models.
