This invention concerns a liposome comprising lipids and at least one active ingredient, wherein at least one of the lipids is a cationic lipid; said liposome exhibiting a net positive charge at physiological conditions at which said liposome preferentially adheres to monocytes in freshly drawn blood when compared to adherence to granulocytes, T-lymphocytes, B-lymphocytes and/or NK cells in freshly drawn blood, to a lipid-based pharmaceutical composition comprising said liposomes and their use in monocytic associated prophylaxis, treatment or amelioration of a condition such as cancer, an infectious disease, an inflammatory disease, an autoimmune disease or allergy.
本发明涉及一种由脂质和至少一种活性成分组成的脂质体,其中至少一种脂质是阳离子脂质;所述脂质体在生理条件下显示出净正电荷,与粘附于新鲜血液中的粒细胞、T淋巴细胞、B淋巴细胞和/或NK细胞相比,所述脂质体优先粘附于新鲜血液中的单核细胞;包含所述脂质体的脂基药物组合物及其在单核细胞相关疾病(如癌症、传染病、炎症性疾病、自身免疫性疾病或过敏症)的预防、治疗或改善中的用途。
