The present invention provides immunostimulatory compositions. Generally, the immunostimulatory compositions include at least partially purified conjugates that include at least one IRM moiety covalently coupled to an antigenic peptide. In some embodiments, the immunostimulatory composition includes monomeric conjugates. In other embodiments, the immunostimulatory composition includes an aggregate of a conjugate and at least one other antigenic peptide (e.g., another conjugate and/or unconjugated peptide). The present invention also provides methods of using such immunostimulatory compositions. In some embodiments, the methods include inducing an immune response by contacting the immunostimulatory composition with an immune cell. In other embodiments, the method includes treating a condition by administering an immunostimulatory composition to a subject in an amount effective to ameliorate at least one symptom or clinical sign of the condition.
本发明提供了免疫刺激组合物。通常,免疫刺激组合物包括至少部分纯化的共轭物,其中至少一个IRM基团与抗原肽共价耦合。在某些实施例中,免疫刺激组合物包括单体共轭物。在其他实施例中,免疫刺激组合物包括一个共轭物和至少一个其他抗原肽的聚集物(例如,另一个共轭物和/或非共轭肽)。本发明还提供了使用这种免疫刺激组合物的方法。在某些实施例中,该方法包括通过将免疫刺激组合物与免疫细胞接触来诱导免疫反应。在其他实施例中,该方法包括通过向受试者施用有效量的免疫刺激组合物来治疗疾病,以改善至少一种症状或临床表现。
