Abstract

Myeloid malignancies stem from a modified hematopoietic stem cell and predominantly include acute myeloid leukemia, myelodysplastic neoplasms, myeloproliferative malignancies, and chronic myelomonocytic leukemia. Myeloid-derived suppressor cells (MDSCs) exhibit immunoregulatory properties by governing the innate and adaptive immune systems, creating a permissive and supportive environment for neoplasm growth. This review examines the key characteristics of MDSCs in myeloid malignancies, highlighting that an increased MDSC count corresponds to heightened immunosuppressive capabilities, fostering an immune-tolerant neoplasm microenvironment. Also, this review analyzes and describes the potential of combined cancer therapies, focusing on targeting MDSC generation, expansion, and their inherent immunosuppressive activities to enhance the efficacy of current cancer immunotherapies. A comprehensive understanding of the implications of myeloid malignancies may enhance the exploration of immunotherapeutic strategies for their potential application.

髓源性抑制细胞:髓源性抑制细胞:对髓系恶性肿瘤和免疫疗法的影响。
髓系恶性肿瘤源自改良的造血干细胞,主要包括急性髓系白血病、骨髓增生异常肿瘤、骨髓增生性恶性肿瘤和慢性粒单核细胞白血病。髓源性抑制细胞(MDSCs)通过调节先天性免疫系统和适应性免疫系统而表现出免疫调节特性,为肿瘤的生长创造了有利的支持性环境。本综述探讨了髓系恶性肿瘤中 MDSCs 的主要特征,强调 MDSC 数量的增加与免疫抑制能力的增强相对应,可促进免疫耐受性肿瘤微环境的形成。此外,这篇综述还分析和描述了癌症综合疗法的潜力,重点关注 MDSC 的生成、扩增及其固有的免疫抑制活动,以提高当前癌症免疫疗法的疗效。全面了解髓系恶性肿瘤的影响有助于探索免疫治疗策略的潜在应用。

期刊介绍: Acta histochemica, a journal of structural biochemistry of cells and tissues, publishes original research articles, short communications, reviews, letters to the editor, meeting reports and abstracts of meetings. The aim of the journal is to provide a forum for the cytochemical and histochemical research community in the life sciences, including cell biology, biotechnology, neurobiology, immunobiology, pathology, pharmacology, botany, zoology and environmental and toxicological research. The journal focuses on new developments in cytochemistry and histochemistry and their applications. Manuscripts reporting on studies of living cells and tissues are particularly welcome. Understanding the complexity of cells and tissues, i.e. their biocomplexity and biodiversity, is a major goal of the journal and reports on this topic are especially encouraged. Original research articles, short communications and reviews that report on new developments in cytochemistry and histochemistry are welcomed, especially when molecular biology is combined with the use of advanced microscopical techniques including image analysis and cytometry. Letters to the editor should comment or interpret previously published articles in the journal to trigger scientific discussions. Meeting reports are considered to be very important publications in the journal because they are excellent opportunities to present state-of-the-art overviews of fields in research where the developments are fast and hard to follow. Authors of meeting reports should consult the editors before writing a report. The editorial policy of the editors and the editorial board is rapid publication. Once a manuscript is received by one of the editors, an editorial decision about acceptance, revision or rejection will be taken within a month. It is the aim of the publishers to have a manuscript published within three months after the manuscript has been accepted
