Liposomes conjugated with anti-H2Kk antibody associate with L929 murine fibroblasts in 6- to 20-fold greater amount than do nonspecific liposomes. The ability of methotrexate-gamma-aspartate to inhibit L929 growth is increased 10-fold when encapsulated in targeted liposomes but is decreased to 50% when encapsulated in liposomes with no specificity for the target cells. Ammonium chloride inhibits the effects of the encapsulated but not the free drug. Soluble antibody does not inhibit the… CONTINUE READING
