Principal progress in development new anticancer therapies, improving efficiency immunotherapeutic tools, personification conventional therapies needs to consider cancer-specific patient-specific programming innate immunity. Intratumoral TAMs their precursors, resident macrophages monocytes, are principal regulators tumor progression therapy resistance. Our review summarizes accumulated evidence for subpopulations number biomarkers, indicating predictive value clinical parameters carcinogenesis resistance, with a focus on solid cancers non-infectious etiology. We present state-of-the-art knowledge about tumor-supporting functions at all stages highlight recently identified by single-cell spatial analytical methods, that discriminate between tumor-promoting tumor-inhibiting TAMs, where both subtypes express combination prototype M1 M2 genes. focuses novel mechanisms involved crosstalk among epigenetic, signaling, transcriptional metabolic pathways TAMs. Particular attention has been given link cell metabolism epigenetic histone lactylation, which can be responsible unlimited protumoral Finally, we explain how interfere currently used therapeutics summarize most advanced data from trials, divide into four categories: inhibition TAM survival differentiation, monocyte/TAM recruitment tumors, functional reprogramming genetic enhancement macrophages.

In solid tumors, tumor-associated macrophages (TAMs) are one of the most numerous populations and play an important role in processes tumor cell invasion, metastasis, angiogenesis. Therefore, TAMs considered promising diagnostic prognostic biomarkers many attempts have been made to influence these cells as part antitumor therapy. There several key principles action on ТАМs: inhibition monocyte/macrophage transition; destruction macrophages; reprogramming macrophage phenotypes (polarization M2 M1); stimulation phagocytic activity CAR-M Despite large number studies this area, date, there no adequate approaches using therapy based alterations TAM functioning that would show high efficacy when administered a mono-regimen for treatment malignant neoplasms. Studies devoted evaluation drugs acting characterized by small sample heterogeneity patient groups; addition, such studies, chemotherapy or immunotherapy is used, which significantly complicates effectiveness agent TAMs. review, we attempted systematize evidence malignancies lung cancer, breast colorectal cervical prostate gastric head neck squamous soft tissue sarcomas.

Unraveling the enigma of tumor-associated macrophages: challenges, innovations, and the path to therapeutic breakthroughs

Frontiers in Immunology, Год журнала: 2023, Номер 14

Опубликована: Ноя. 14, 2023

Tumor-associated macrophages (TAMs) are integral to the tumor microenvironment (TME), influencing cancer progression significantly. Attracted by cell signals, TAMs exhibit unparalleled adaptability, aligning with dynamic milieu. Their roles span from promoting growth and angiogenesis modulating metastasis. While substantial research has explored fundamentals of TAMs, comprehending their adaptive behavior, leveraging it for novel treatments remains challenging. This review delves into TAM polarization, metabolic shifts, complex orchestration cytokines chemokines determining functions. We highlight complexities TAM-targeted focusing on adaptability potential variability in therapeutic outcomes. Moreover, we discuss synergy integrating TAM-focused strategies established treatments, such as chemotherapy, immunotherapy. Emphasis is laid pioneering methods like reprogramming immunotherapy adoption single-cell technologies precision intervention. synthesis seeks shed light TAMs’ multifaceted cancer, pinpointing prospective pathways transformative enhancing modalities oncology.

The next frontier in immunotherapy: potential and challenges of CAR-macrophages

Experimental Hematology and Oncology, Год журнала: 2024, Номер 13(1)

Опубликована: Авг. 5, 2024

Abstract Chimeric antigen receptor macrophage (CAR-MΦ) represents a significant advancement in immunotherapy, especially for treating solid tumors where traditional CAR-T therapies face limitations. CAR-MΦ offers promising approach to target and eradicate tumor cells by utilizing macrophages’ phagocytic antigen-presenting abilities. However, challenges such as the complex microenvironment (TME), variability expression, immune suppression limit their efficacy. This review addresses these issues, exploring mechanisms of action, optimal construct designs, interactions within TME. It also delves into ex vivo manufacturing CAR-MΦ, discussing autologous allogeneic sources importance stringent quality control. The potential synergies integrating with existing cancer like checkpoint inhibitors conventional chemotherapeutics are examined highlight possible enhanced treatment outcomes. Furthermore, regulatory pathways scrutinized alongside established protocols cells, identifying unique considerations essential clinical trials market approval. Proposed safety monitoring frameworks aim manage adverse events, cytokine release syndrome, crucial patient safety. Consolidating current research insights, this seeks refine therapeutic applications, overcome barriers, suggest future directions transition from experimental platforms standard care options.

From silent partners to potential therapeutic targets: macrophages in colorectal cancer

Cancer Immunology Immunotherapy, Год журнала: 2025, Номер 74(4)

Cancer cells grow and survive in the tumor microenvironment, which is a complicated process. As key part of how colorectal cancer (CRC) progresses, tumor-associated macrophages (TAMs) exhibit double role. Through angiogenesis, this TAM can promote growth cancers. Although being able to modify adjust immune great advantage, these also anti-cancer properties including direct killing cells, presenting antigens, aiding T cell-mediated responses. The delicate regulatory mechanisms between system tumors are composed complex network pathways regulated by several factors hypoxia, metabolic reprogramming, cytokine/chemokine signaling, cell interactions. Decoding figuring out systems become significant building targeted treatment programs. Targeting TAMs CRC involves disrupting chemokine signaling or adhesion molecules, reprogramming them an anti-tumor phenotype using TLR agonists, CD40 modulation, selectively removing subsets that growth. Multi-drug resistance, absence accurate biomarker, drug non-specificity major problems. Combining macrophage-targeted therapies with chemotherapy immunotherapy may revolutionize treatment. Macrophage studies will advance new technology multi-omics methodologies help us understand build specific efficient treatments.
