Liposomal amphotericin B was immunosuppressive on target cell lysis in vitr
o and on protection mediated by cytotoxic CD8 T cells in murine listeriosis
. When dosages usually used for therapy in humans were compared, the immuno
suppressive effect of 5 mg of liposomal amphotericin B/kg of body weight/da
y was similar to that of standard amphotericin B at 1 mg/kg/day, but a dosa
ge of liposomal amphotericin B of 1 mg/kg/day was not suppressive in vivo.
