Induction of Antitumor Cytotoxic Lymphocytes Using Engineered Human Primary Blood Dendritic Cells

Cancer Vaccine is medicinal agent which can be utilized to elicit a natural immune response by enhancing T cell responses or increasing antibody production. With breath of experience and knowledge in the area of cancer vaccine, Creative Biolabs is dedicated to helping our clients successfully initiate and complete critical phases of cancer vaccine product discovery and development. Now we provide engineered human primary blood dendritic cells to induce antitumor cytotoxic lymphocytes to facilitate your immunotherapy projects.

• The Best Helper to Accelerate and Innovate Your Immuno-Cell Therapy
• The Most Valuable Cooperator for Developing the Best Candidate to Boost Your Project

Our Scientific Inspiration

As one of the current most popular immunotherapies, dendritic cell-based immunotherapy has shown its strength by boosting the patients’ own immune system to destroy cancer. DC-based immunotherapy has achieved significant clinical benefits, while some technical hurdles (including DC preparation, activation, cancer/testis antigen delivery) exist which limit its broad applications. Long Wu’s team has reported an influential study about “induction of antitumor cytotoxic lymphocytes using engineered human primary blood dendritic cells”. They reported the development of immortalized and constitutively activated human primary blood dendritic cell lines (ihv-DCs). ihv-DCs can induce the generation of CTA-specific cytotoxic T lymphocytes (CTLs). These cytotoxic lymphocytes show the efficacy of lung metastasis suppression in NSG mice (see Fig.1). This approach can facilitate the development of cell-based immunotherapy to treat lung cancer.

Induction of Antitumor Cytotoxic Lymphocytes Using Engineered Human Primary Blood Dendritic Cells

Inspired by this approach, our scientists developed a series of assays to facilitate your dendritic cell-based immunotherapy projects. Any individual module or integrated solution are all available.

• Development of human primary blood dendritic cell lines (ihv-DC cell lines);
• Expression of TLRs, cytokines, and cellular signaling molecules in ihv-DCs;
• Induction of tumor-associated antigen-specific CTLs by ihv-DCs;
• Anti-cancer efficacy evaluation by ihv-DC primed cytotoxic lymphocytes in mice models.

This approach shows several major significances as follows:

• Primary blood DCs are expanded at unlimited amounts;
• The DCs are constitutively activated and readily available to prime naïve T lymphocytes;
• The DCs can be genetically modified to present specific tumor antigens, and induce the generation of antigen-specific T and NK cells in high efficiency;
• The produced cytotoxic T and NK cells can suppress tumor growth and cancer metastasis in cancer mouse models.
