Title

HIGH-EXPRESSION OF CHIMERIC ANTIGEN RECEPTOR ON T LYMPHOCYTES BY GENOMIC INSERTION

Pages

  8-18

Abstract

 Background and Objectives: The specific activation of the immune system especially T lymphocytes has been a long-term goal of CANCER IMMUNOTHERAPY. In an approach to induce the patient’s own immune cells, chimeric antigen receptors (CAR) were used to activate cytotoxic T lymphocytes. The CAR consists of an antigen binding domain of antibody molecule linked through an extracellular linker to transmembrane and cytoplasmic domains of lymphocyte-triggering moieties.Materials and Methods: In our research group, variable domains of heavy chain antibodies (VHH or nanobody) derived from camelids were used instead of the antigen-binding domain in chimeric receptors constructs. To obtain a stable and increased expression of VHH harboring CAR, the PhiC31 INTEGRASE system was used for CAR gene integration into the T-cell genome. Constructs expressing CAR and PhiC31 INTEGRASE were co-transfected into the Jurkat cell line and CAR expression was quantified after one day and 30 days after transfection by a semi-quantitative RT-PCR method.Results: Our results on day 30 confirmed that co-transfection of PhiC31 INTEGRASE constructs and CAR expressing constructs resulted in stable and high expression of the receptors.Conclusions: Based on our results, we conclude that PhiC31 INTEGRASE enzyme can be used for IMMUNOTHERAPY of CANCER mediated by T cells expressing chimeric recetors.
