The present invention provides targeted delivery systems to deliver pharmaceuticals to irradiated tissue comprising a biomolecule carrier, a targeting moiety to cellular adhesion molecules and a pharmaceutical. The present invention also provides methods of selectively targeting endothelial tissue for delivery of a pharmaceutical thereto and of treating a pathophysiological state in an individual using the targeted delivery systems disclosed herein. Further provided is a method of optimizing an immunoliposome for specific targeting of a pharmaceutical encapsulated therein to irradiated tissue by selecting a liposome that has a greater rate of adhesion to the irradiated tissue than a rate of uptake by the reticuloendothelial system.
本发明提供了向照射组织输送药物的靶向输送系统,该系统包括生物大分子载体、细胞粘附分子靶向分子和药物。本发明还提供了选择性靶向内皮组织递送药物的方法,以及使用本发明公开的靶向递送系统治疗个体病理生理状态的方法。本发明还提供了一种优化免疫脂质体的方法,通过选择一种与辐照组织的粘附率大于网状内皮系统吸收率的脂质体,将其中封装的药物特异性靶向辐照组织。
