Targeting of liposomes to lymph nodes

Recently, liposomes have received much attention as lymph-node drugdelivery agents. This interest in the development of new methods of lymph-node drug-delivery stems from the increasing awareness of the importance of lymph nodes in cancer prognosis, their importance for vaccine immune stimulation and the realization that the lymph nodes harbor human immunodeficiency virus (HIV) as well as other infectious disease (1-4). New methods of delivering drugs and antigens to lymph nodes are currently under investigation.
