Zlatareva I, Wu Y. Local γδ T cells: translating promise to practice in cancer immunotherapy. Br J Cancer 2023; 129:393-405. [PMID: 37311978 PMCID: PMC10403623 DOI: 10.1038/s41416-023-02303-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 05/06/2023] [Accepted: 05/15/2023] [Indexed: 06/15/2023] Open
Abstract
Rapid bench-to-bedside translation of basic immunology to cancer immunotherapy has revolutionised the clinical practice of oncology over the last decade. Immune checkpoint inhibitors targeting αβ T cells now offer durable remissions and even cures for some patients with hitherto treatment-refractory metastatic cancers. Unfortunately, these treatments only benefit a minority of patients and efforts to improve efficacy through combination therapies utilising αβ T cells have seen diminishing returns. Alongside αβ T cells and B cells, γδ T cells are a third lineage of adaptive lymphocytes. Less is known about these cells, and they remain relatively untested in cancer immunotherapy. Whilst preclinical evidence supports their utility, the few early-phase trials involving γδ T cells have failed to demonstrate convincing efficacy in solid cancers. Here we review recent progress in our understanding of how these cells are regulated, especially locally within tissues, and the potential for translation. In particular, we focus on the latest advances in the field of butyrophilin (BTN) and BTN-like (BTNL) regulation of γδ T cells and speculate on how these advances may address the limitations of historical approaches in utilising these cells, as well as how they may inform novel approaches in deploying these cells for cancer immunotherapy.

Abstract
Owing to their antitumor and major histocompatibility complex (MHC)-independent capacities, γδ T cells have gained popularity in adoptive T-cell immunotherapy in recent years. However, many unknowns still exist regarding γδ T cells, and few clinical data have been collected. Therefore, this review aims to describe all the main features of the applications of γδ T cells and provide a systematic view of current γδ T-cell immunotherapy. Specifically, this review will focus on how γδ T cells performed in treating cancers in clinics, on the γδ T-cell clinical trials that have been conducted to date, and the role of γδ T cells in the pharmaceutical industry.

Abstract
γδT cells represent a small percentage of T cells in circulation but are found in large numbers in certain organs. They are considered to be innate immune cells that can exert cytotoxic functions on target cells without MHC restriction. Moreover, γδT cells contribute to adaptive immune response via regulating other immune cells. Under the influence of cytokines, γδT cells can be polarized to different subsets in the tumor microenvironment. In this review, we aimed to summarize the current understanding of antigen recognition by γδT cells, and the immune regulation mediated by γδT cells in the tumor microenvironment. More importantly, we depicted the polarization and plasticity of γδT cells in the presence of different cytokines and their combinations, which provided the basis for γδT cell-based cancer immunotherapy targeting cytokine signals.

Sheweita SA, Ammar RG, Sabra SA, Sultan AS. Letrozole and zoledronic acid changed signalling pathways involved in the apoptosis of breast cancer cells. J Taibah Univ Med Sci 2021; 16:112-120. [PMID: 33603639 PMCID: PMC7858005 DOI: 10.1016/j.jtumed.2020.10.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 10/25/2020] [Accepted: 10/31/2020] [Indexed: 11/26/2022] Open
Abstract
Objectives Oestrogen plays a key role in the development of breast malignancies. Therefore, aromatase inhibitors (e.g. letrozole [LTZ]) are widely used in the treatment of breast cancer. On the other hand, oestrogen is important to the integrity of bone mass. Research has shown that zoledronic acid (ZLA) may prevent osteoporosis. Therefore, the present research aims to investigate the effect of a combination of LTZ and ZLA in the treatment of breast cancer and in reducing osteoporosis in patients with breast cancer. Methods We used immunocytochemistry and Western immunoblotting techniques in this study. Results We observed that LTZ inhibited cellular growth of Michigan Cancer Foundation-7 (MCF-7) and T-47D at IC50 (70 ± 0.001) and (140 ± 0.004) nM, respectively, whereas ZLA inhibited cellular growth at IC50 (50 ± 0.005) μM and (150 ± 0.004) μM for MCF-7 and T-47D cell lines, respectively. Interestingly, the LTZ and ZLA combination down-regulated the protein expression of signal transducer and activator of transcription 3 (STAT3) and up-regulated BRCA1 protein expression in both cell lines. Moreover, a notable enhancement in the nuclear localisation of the BRCA1 protein was obtained after treatment of T-47D cells with LTZ for 24 h compared to the control cells. In contrast, there was a reduction in the nuclear localisation of STAT3 protein, which could be an attractive target for inhibition of breast cancer proliferation and progression. Conclusion Our study has shown that a combination of LTZ and ZLA enhanced apoptosis and inhibited growth of both breast cancer cell lines. This combination can be used to maintain bone integrity in women with breast cancer.

Abstract
A straightforward synthesis of benzonitriles is achieved via amino-catalyzed [3+3] benzannulation of α,β-unsaturated aldehydes and 4-arylsulfonyl-2-butenenitriles. Using pyrrolidine as an organocatalyst via iminium activation, a series of substituted benzonitriles were obtained in good to high yields in a regioselective manner. This reaction can proceed smoothly under mild reaction conditions and without the aid of any metals, additional oxidants, or strong bases, thus making this an efficient and environmentally friendly method to access benzonitriles.
