DESCRIPTION (provided by applicant): The broad premise underlying our research is that the application of biomaterials science to immunology may dramatically impact how diseases of the immune system are treated in the future. Currently, many experimental cancer vaccines isolate and program immune cells outside the body, and introduce the programmed cells back into the patient (e.g., adoptive T cell transfer, dendritic cell-based vaccinations) to elicit anti-tumor responses. This application proposes a new approach to breast cancer vaccines, in which biomaterials that can be introduced into the body in a minimally invasive manner are used to program, in situ, host dendritic cells to generate a potent immune response. The specific hypothesis to be addressed in this project is that an injectable biomaterial system that mimics bacterial infection, while presenting tumor antigens, can effectively recruit, mature and disperse host dendritic cells capable of stimulating specific T-cell populations and eliciting a strong anti tumor response in the context of breast cancer. This hypothesis will be tested with the following aims: (1) Cryogelation will be utilized to fabricate macroporous gel materials that can be introduced into the body in a minimally invasive manner, while subsequently allowing significant host cell infiltration, (2) DC recruitment factors and Toll Like Receptor ligands will be encapsulated and released in a sustained manner from the gels, and their effects on the types and numbers of DC recruited to the vaccine site will be investigated, and (3) The ability of these cryogels to provide effective prophylactic and therapeutic breast cancer vaccines in rodent models will be tested. The goal of this work is to develop a functional cancer vaccine that can be used to treat women suffering from breast cancer. A successful cancer vaccine would not only be capable of causing regression of a primary tumor, but could also target metastasis in sites distant to the original tumor site. Further, the memory component of the adaptive immune system may provide protection against recurrence in the future. Success in this effort would have a dramatic impact on women suffering from breast cancer, and could potentially have significant impact in the development of vaccines for other types of cancer.

描述（由申请人提供）：我们的研究基础的主要前提是，生物材料科学在免疫学上的应用可能会极大地影响免疫系统疾病的未来疾病。目前，许多实验性癌症疫苗分离并编程了人体外部的免疫细胞，并将程序性细胞重新引入患者（例如，产卵T细胞转移，基于树突状细胞的疫苗接种）以引起抗肿瘤反应。该应用提出了一种用于乳腺癌疫苗的新方法，其中可以以微创方式引入体内的生物材料用于原位对宿主树突状细胞进行编程，以产生有效的免疫反应。该项目要解决的具体假设是，模仿细菌感染的可注射的生物材料系统可以有效地募集，成熟和分散宿主的树突状细胞，能够刺激特定的T细胞群体并引起强抗强大的抗体抗体 乳腺癌背景下的肿瘤反应。 This hypothesis will be tested with the following aims: (1) Cryogelation will be utilized to fabricate macroporous gel materials that can be introduced into the body in a minimally invasive manner, while subsequently allowing significant host cell infiltration, (2) DC recruitment factors and Toll Like Receptor ligands will be encapsulated and released in a sustained manner from the gels, and their effects on the types and numbers of DC recruited将研究疫苗部位，（3）将测试这些冷冻凝胶在啮齿动物模型中提供有效预防性和治疗性乳腺癌疫苗的能力。这项工作的目的是开发一种功能性癌症疫苗，可用于治疗患有乳腺癌的女性。成功的癌症疫苗不仅能够引起原发性肿瘤的消退，而且还可以靶向与原始肿瘤部位远处的转移。此外，自适应免疫系统的记忆成分可能会在将来提供防止复发的保护。在这项工作中的成功将对患有乳腺癌的女性产生巨大影响，并可能对其他类型的癌症的疫苗开发产生重大影响。
