Lipid conjugates for enhanced delivery of cargo to the lymph nodes are disclosed. The lipid conjugates typically include three domains: a lipophilic domain that binds to albumin, a polar block domain, and a cargo such as a molecular adjuvant or immunostimulatory compound (such as an oligonucleotide) or antigenic peptide. Depending on the cargo, the length and compositions of the polar block can be tailored to push the equilibrium toward albumin binding, stable micelle formation, or cell insertion. The conjugates can be administered to a subject, for example, a subject with cancer or an infection, to induce or enhance a robust immune response in the subject.
本发明公开了用于增强将载荷输送到淋巴结的脂质共轭物。脂质共轭物通常包括三个区域:一个与白蛋白结合的亲脂区、一个极性区块区域和一个载荷,例如分子佐剂或免疫刺激化合物(如寡核苷酸)或抗原肽。根据载荷,可以调整极性区块的长度和组成,以推动平衡向白蛋白结合、稳定的胶束形成或细胞插入。这些共轭物可以被给予一个受试者,例如一个患有癌症或感染的受试者,以诱导或增强受试者的强大免疫反应。
