Dr. Benjamin Tjoa presents this ePoster, highlighting data emphasizing the importance of antigen presentation in selecting an antigen for targeting by the immune system. Several T cells lines specific for common tumor antigens were developed, with the aim to understand the cytotoxic capability of the T cells and the degree to which these tumor antigens are presented by HLA class I molecules. The IncuCyte® live cell imaging system was used to measure the cytotoxic ability of tumor specific T cells using appropriate tumor cell lines as targets.
