Abstract
The effectiveness and mechanisms of γδT-cell immunotherapy in lung cancer remain unclear. In this study, we assessed the effects of continuous, low-dose γδT-cell intervention on lung cancer cells. We cultured γδT cells with a lung cancer cell line (A549) and replaced the γδT-cell population every 48 hours. The killing effect of γδTcells on A549 cells and the Half-maximal inhibitory concentration (IC50) value were detected by the cholecystokinin octapeptide (CCK-8) method. The levels of perforin, granzyme B and the inflammatory factors interleukin-6 (IL-6), interferon (IFN)-γ, and tumor necrosis factor-alpha (TNF-a), in the supernatants of cocultured cells were measured by ELISA. The protein expression of Bcl-2, Bax, PI3K and Akt was detected by western blotting. Our results indicated that γδT-cell treatment decreased the protein expression of Bcl-2, PI3K, and AKT but upregulated that of Bax. Moreover, γδT-cell treatment increased perforin and granzyme B release related to the Bax/Bcl-2 signaling pathway. In addition, γδT-cell-mediated cytolysis for A549 cells involved the PI3K/AKT pathway. In vivo results were consistent with the in vitro results. γδT-cell immunotherapy integrated regulation of a signaling pathway network involving the mutual regulation of apoptosis and proliferation. γδT-cell immunotherapy could be used to enhance the cytotoxic killing of lung cancer cells.

A Simple and Robust Single-Step Method for CAR-Vδ1 γδT Cell Expansion and Transduction for Cancer Immunotherapy. Front Immunol 2022; 13:863155. [PMID: 35711450 PMCID: PMC9197253 DOI: 10.3389/fimmu.2022.863155] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 04/25/2022] [Indexed: 12/05/2022] Open
Abstract
The γδT cell subset of peripheral lymphocytes exhibits potent cancer antigen recognition independent of classical peptide MHC complexes, making it an attractive candidate for allogeneic cancer adoptive immunotherapy. The Vδ1-T cell receptor (TCR)-expressing subset of peripheral γδT cells has remained enigmatic compared to its more prevalent Vγ9Vδ2-TCR and αβ-TCR-expressing counterparts. It took until 2021 before a first patient was dosed with an allogeneic adoptive Vδ1 cell product despite pre-clinical promise for oncology indications stretching back to the 1980s. A contributing factor to the paucity of clinical progress with Vδ1 cells is the lack of robust, consistent and GMP-compatible expansion protocols. Herein we describe a reproducible one-step, clinically translatable protocol for Vδ1-γδT cell expansion from peripheral blood mononuclear cells (PBMCs), that is further compatible with high-efficiency gene engineering for immunotherapy purposes. Briefly, αβTCR- and CD56-depleted PBMC stimulation with known-in-the-art T cell stimulators, anti-CD3 mAb (clone: OKT-3) and IL-15, leads to robust Vδ1 cell expansion of high purity and innate-like anti-tumor efficacy. These Vδ1 cells can be virally transduced to express chimeric antigen receptors (CARs) using standard techniques, and the CAR-Vδ1 exhibit antigen-specific persistence, cytotoxicity and produce IFN-γ. Practicable, GMP-compatible engineered Vδ1 cell expansion methods will be crucial to the wide-spread clinical testing of these cells for oncology indications.
