Abstract
Chimeric antigen receptor (CAR) T cell therapy has revolutionized the treatment of malignancies, especially hematological tumors, but toxicities have tempered its success. The main impediments to the development of CAR-T cell therapies are the following: cytokine release syndrome (CRS), immune-effector-cell-associated neurotoxicity syndrome (ICANS), tumor lysis syndrome (TLS), and on-target/off-tumor toxicity (OTOT). This review summarizes these side effects' underlying mechanisms and manifestations over time. It provides potential prevention and treatment according to the consensus grading, stressing the significance of establishing strategies that anticipate, reduce, and navigate the beginning of these side effects. It is essential to fully comprehend the mechanisms underlying these toxicities to create efficient treatment and preventive approaches.

Superior antitumor immunotherapy efficacy of kynureninase modified CAR-T cells through targeting kynurenine metabolism. Oncoimmunology 2022; 11:2055703. [PMID: 35355679 PMCID: PMC8959528 DOI: 10.1080/2162402x.2022.2055703] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 01/24/2022] [Accepted: 03/04/2022] [Indexed: 01/17/2023] Open
Abstract
Accumulated oncometabolites in the tumor microenvironment (TME) suppresses the metabolism, expansion, and function of T cells. Immunosuppressive TME also impeded Chimeric Antigen Receptor (CAR)-T cells mediated cytotoxicity since CAR-T cells had to adapt the in vivo metabolic characteristics with high levels of oncometabolites. We screened oncometabolites for the inhibition of glucose uptake in CD8 + T cells and found Kynurenine (Kyn) showed the strongest inhibiting effect on glucose uptake. In vitro experiments showed that 120 μM Kyn treatment in CD8 + T cells resulted in inhibiting the expansion of CD8 + T cells, decreasing the production of granzyme B and interferon-γ. CAR-T cells mediated cytotoxicity was also impaired by the high Kyn treatment from killing assay. We then explored the anti-tumor effect of Kynureninase (KYNU) modified CAR-T cells through catabolism o oncometabolites Kyn. KYNU over-expression (OE) CAR-T cells showed a superior killing effect against cancer cells even in the immunosuppressive TME with high Kyn levels. In vivo experiments confirmed KYNU-OE CAR-T cells showed an excellent anti-tumor effect in a TME with high Kyn levels since it improved the survival of mice bearing NALM6 cancer cells and NALM6-IDO1 cancer cells. The KYNU-modified CAR-T cells displayed distinct phenotypes related to the expansion, function, and memory differentiation status of CAR-T cells. This study explores an immunotherapy strategy for patients with alterations in Kyn metabolism. KYNU-OE CAR-T cells take advantage of Kyn catabolism to improve anti-tumor activity in the metabolic immunosuppressive TME with high Kyn.

Chimeric antigen receptor- and natural killer cell receptor-engineered innate killer cells in cancer immunotherapy. Cell Mol Immunol 2021; 18:2083-2100. [PMID: 34267335 PMCID: PMC8429625 DOI: 10.1038/s41423-021-00732-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Accepted: 06/18/2021] [Indexed: 02/06/2023] Open
Abstract
Chimeric antigen receptor (CAR)-engineered T-cell (CAR-T) therapy has demonstrated impressive therapeutic efficacy against hematological malignancies, but multiple challenges have hindered its application, particularly for the eradication of solid tumors. Innate killer cells (IKCs), particularly NK cells, NKT cells, and γδ T cells, employ specific antigen-independent innate tumor recognition and cytotoxic mechanisms that simultaneously display high antitumor efficacy and prevent tumor escape caused by antigen loss or modulation. IKCs are associated with a low risk of developing GVHD, thus offering new opportunities for allogeneic "off-the-shelf" cellular therapeutic products. The unique innate features, wide tumor recognition range, and potent antitumor functions of IKCs make them potentially excellent candidates for cancer immunotherapy, particularly serving as platforms for CAR development. In this review, we first provide a brief summary of the challenges hampering CAR-T-cell therapy applications and then discuss the latest CAR-NK-cell research, covering the advantages, applications, and clinical translation of CAR- and NK-cell receptor (NKR)-engineered IKCs. Advances in synthetic biology and the development of novel genetic engineering techniques, such as gene-editing and cellular reprogramming, will enable the further optimization of IKC-based anticancer therapies.
