Adoptive transfer of T cells genetically modified to express antigen receptor transgenes has shown promise for the treatment of cancer. However, the development of T-cell redirecting therapies relies on the use of primary immune cells and is hampered by the lack of easy-to-use model systems and sensitive readouts to facilitate candidate screening and development. Particularly, testing T-cell receptor (TCR)-specific responses in primary T cells and immortalized T cells is confounded by the presence of endogenous TCR expression which results in mixed alpha/beta TCR pairings and compresses assay readouts. Herein, we describe the development of a novel cell-based TCR knockout (TCR-KO) reporter assay platform for the development and characterization of T-cell redirecting therapies. CRISPR/Cas9 was used to knockout the endogenous TCR chains in Jurkat cells stably expressing a human interleukin-2 promoter-driven luciferase reporter gene to measure TCR signaling. Reintroduction of a transgenic TCR into the TCR-KO reporter cells results in robust antigen-specific reporter activation compared with parental reporter cells. The further development of CD4/CD8 double-positive and double-negative versions enabled low-avidity and high-avidity TCR screening with or without major histocompatibility complex bias. Furthermore, stable TCR-expressing reporter cells generated from TCR-KO reporter cells exhibit sufficient sensitivity to probe in vitro T-cell immunogenicity of protein and nucleic acid-based vaccines. Therefore, our data demonstrated that TCR-KO reporter cells can be a useful tool for the discovery, characterization, and deployment of T-cell immunotherapy.</p>","PeriodicalId":15996,"journal":{"name":"Journal of Immunotherapy","volume":"46 3","pages":"96-106"},"PeriodicalIF":3.9,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/7a/28/cji-46-96.PMC9988225.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10131959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, novel therapeutic strategies are required for the successful treatment of these patients. One possibility is cellular immunotherapy with chimeric antigen receptor T cells. However, the time delay until cells are available and the limited number of effector cells due to the impaired immune system of these patients potentially compromises the efficacy of this approach. Another promising attempt might be the therapy with γδ T cells. Once activated, they exhibit various antitumor effects against several types of malignancies. Furthermore, they can be safely used in an allogeneic setting and can be multiplied in vivo as already demonstrated in clinical studies. In vitro data, in addition, show that the cytotoxicity of γδ T cells can be significantly enhanced by monoclonal antibodies. Here we present a patient, who suffered from Richter transformation and did not respond to several lines of immunochemotherapy. Due to the lack of further therapy options, we conducted an individual therapy with adoptive transfer of haploidentical γδ T cells combined with the application of the monoclonal antibody obinutuzumab. A histologically confirmed complete remission was achieved through this therapy approach, whereby relevant side effects were not seen.
