摘要:
One embodiment of the current disclosure relates to an immune-modulating composition comprising a hydrogel-forming polymer, an immune-modulating biomolecule operable to recruit or retain an immune cell, and an antigen-related biomolecule. Another embodiment of the current disclosure relates to a method of providing an antigen to an antigen presenting cell in an animal by administering to the animal at an administration site an immune-modulating composition as described above. Next, one forms a hydrogel in-situ from the hydrogel-forming polymer, then recruits at least one antigen presenting cell to the administration site using the immune-modulating biomolecule, and finally inducing phagocytosis of the at least one antigen- related biomolecule by the antigen presenting cell.
摘要:
The present invention includes compositions and methods for the controlled delivery of active agents, e.g., drugs, based on one or more release triggers found in the environment in which the active agent-loaded particle is located. The composition and methods include a polymer network having a polymer cross-linked by peptides that include one or more proteolytic cleavage sites.
