    More than 43,500 women are expected to die from breast cancer in 2021 see more

    A Clemson University study could lead to new immunotherapy for breast cancer. The study, according to the university, provides the foundation of using cells in our bodies to target cancer cells.

    Clemson researchers have used the immune system’s natural killer cells — which the body uses to fight off certain types of infections — to go after the breast cancer cells by bridging the two cells with a fusion of proteins the researchers developed.

    “The idea is to use this bifunctional protein to bridge the natural killer cells and breast cancer tumor cells,” said Yanzhang “Charlie” Wei, a professor in the College of Science’s Department of Biological Sciences. “If the two cells are brought close enough together through this receptor ligand connection, the natural killer cells can release what I call killing machinery to have the tumor cells killed.”

    Breast cancer kills 43,000 women each year in the U.S., according to the American Cancer Society and one in eight women and one in 1,000 men will develop invasive breast cancer.

    “Very simply, cancer is uncontrolled cell growth. Some cells will become abnormal and have the potential to become cancer,” Wei explained. “The immune system can recognize these abnormal cells and destroy them before they become cancer cells. Unfortunately for those who develop cancer, the immune system is not working very well because of gene mutations and environmental factors. The result is that the cancer cells won the fight between the immune system and the tumors.”

    Clemson’s researchers focused on triple-negative breast cancer, the most lethal type of breast cancer, and prolactin receptors.

    KIYATEC presenting at Socierty for Immunotherapy of Cancer conference see more

    GREENVILLE, S.C. – November 5, 2019 – KIYATEC, Inc. today announced that it will present data characterizing in vitro response to checkpoint inhibitors in solid tumors, a capability that addresses an important need in preclinical development of immuno-oncology (I/O) therapies. The data will be presented at the 2019 Society for Immunotherapy of Cancer (SITC) Annual Meeting, to be held November 6-10 in National Harbor, MD. 

    Biologically relevant replication of complex interactions of human immune cells with tumor cells is an ongoing challenge using traditional preclinical models. Evidence presented by KIYATEC will highlight the utility of its in vitro 3D cell culture technology platform to characterize the tumor biology and immune activation and infiltration that precipitates response to checkpoint inhibitors across multiple solid tumor types. Data includes:

    • Complex 3D cultures derived from tumor cell lines or primary tumor tissue, incorporating allogeneic or autologous immune cells
    • High-throughput spheroid models used to detect dose-dependent response to checkpoint blockade and correlate with immune cell activation
    • Complex microtumor models that mirror immune cell infiltration, therapy-mediated reduction of microtumor growth and secretion of cytokines

    “KIYATEC is pioneering advances in 3D cell culture technologies to address the unmet needs of biopharmaceutical companies engaged in pre-clinical testing of their I/O compounds,” said Matthew Gevaert, CEO of KIYATEC. “Our emerging I/O models are currently being productively deployed across a number of pre-clinical initiatives and we anticipate that activity to increase as more drug developers become aware of our unique capabilities.”

    Presentation Details

    Following are key details of the SITC poster presentation:


    • Poster: P3
    • Title: Predicting patient response to checkpoint blockade therapy using in vitro 3D cultures
    • Date and Time:  Friday, November 8, 12:30 – 2:00 pm, 6:30 – 8:00 pm, EST
