Abstract

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited treatment options and a poor prognosis. Immunotherapy has emerged as a promising approach for TNBC, with tumor-infiltrating immune cells (TICs) in the tumor microenvironment (TME) serving as a critical cellular basis for its efficacy. However, the success of immunotherapy in TNBC is often limited due to the immunosuppressive nature of the TME and the heterogeneity of TNBC. Ferroptosis, a form of iron-dependent programmed cell death regulated by metabolic networks including iron, glutathione (GSH), and lipid metabolism, has shown potential to enhance anti-tumor immunity. Recent studies have demonstrated that ferroptosis can modulate immune responses by promoting the infiltration and activation of TICs, thereby improving the outcomes of immunotherapy. However, ferroptosis in immunosuppressive cells such as regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) can trigger an "immunosuppressive wave," affecting other immune cells in the tumor immune microenvironment. This demonstrates the dual role of ferroptosis in TNBC therapy, emphasizing the need for a nuanced understanding of its effects on different immune cells and tumor cells. Herein, we further elaborate the role of ferroptosis in TNBC cells and its interactions with tumor-infiltrating immune cells (TICs) within the TME.

TNBC中的铁下垂:与肿瘤浸润免疫细胞的相互作用及其治疗意义。
三阴性乳腺癌(TNBC)是一种侵袭性乳腺癌亚型,治疗选择有限,预后较差。免疫治疗已成为治疗TNBC的一种有前景的方法,肿瘤微环境(TME)中的肿瘤浸润免疫细胞(TICs)是其疗效的关键细胞基础。然而,由于TME的免疫抑制性质和TNBC的异质性,TNBC免疫治疗的成功往往受到限制。铁死亡是铁依赖性程序性细胞死亡的一种形式,受铁、谷胱甘肽(GSH)和脂质代谢等代谢网络的调节,已显示出增强抗肿瘤免疫的潜力。最近的研究表明,铁下垂可以通过促进tic的浸润和激活来调节免疫反应,从而改善免疫治疗的效果。然而,调节性T细胞(Tregs)和骨髓源性抑制细胞(MDSCs)等免疫抑制细胞中的铁下垂可触发“免疫抑制波”,影响肿瘤免疫微环境中的其他免疫细胞。这表明铁下垂在TNBC治疗中的双重作用,强调需要细致了解其对不同免疫细胞和肿瘤细胞的影响。在此,我们进一步阐述了铁下垂在TNBC细胞中的作用及其与TME内肿瘤浸润免疫细胞(TICs)的相互作用。
