Tumor-infiltrating myeloid cells (TIMs), which encompass tumor-associated macrophages (TAMs), neutrophils (TANs), myeloid-derived suppressor (MDSCs), and dendritic (TADCs), are of great importance in tumor microenvironment (TME) integral to both pro- anti-tumor immunity. Nevertheless, the phenotypic heterogeneity functional plasticity TIMs have posed challenges fully understanding their complexity roles within TME. Emerging evidence suggested that presence is frequently linked prevention cancer treatment improvement patient outcomes survival. Given pivotal function TME, recently been recognized as critical targets for therapeutic approaches aimed at augmenting immunostimulatory cell populations while depleting or modifying those immunosuppressive. This review will explore important properties related immunity, angiogenesis, metastasis. We also document latest strategies targeting preclinical clinical settings. Our objective illustrate potential immunological may improve existing treatments.

Ovarian cancer (OC) remains one of the most lethal gynecological malignancies, largely due to its late-stage diagnosis and high recurrence rates. Chronic inflammation is a critical driver OC progression, contributing immune evasion, tumor growth, metastasis. Inflammatory cytokines, including IL-6, TNF-α, IL-8, as well key signaling pathways such nuclear factor kappa B (NF-kB) signal transducer activator transcription 3 (STAT3), are upregulated in OC, promoting tumor-promoting environment. The microenvironment (TME) characterized by cells like tumor-associated macrophages (TAMs) regulatory T (Tregs), which suppress anti-tumor responses, facilitating evasion. Furthermore, utilize checkpoint pathways, PD-1/PD-L1, inhibit cytotoxic cell activity. Targeting these inflammatory evasion mechanisms offers promising therapeutic strategies. COX-2 inhibitors, Janus kinase/signal (JAK/STAT) pathway blockers, NF-kB inhibitors have shown potential preclinical studies, while targeting PD-1/PD-L1 CTLA-4 been explored with mixed results OC. Additionally, emerging research on microbiome inflammation-related biomarkers, microRNAs (miRNAs) exosomes, points new opportunities for early detection precision medicine. Future approaches treatment must focus personalized strategies that target TME, integrating anti-inflammatory therapies immunotherapy enhance patient outcomes. Continued into interplay between essential developing effective, long-lasting treatments.

Metal–organic frameworks (MOFs) are a class of inorganic-organic hybrid nanoparticles formed by the coordination metal ions/clusters and organic ligands. Due to their high porosities, large surface areas, adjustable structures, responsiveness light/sound, etc., MOFs have shown great clinical potential in field tumor therapy. Tumor immunotherapy exerts antitumor effects through reshaping immune microenvironment, showing significant preclinical advantages. Based on mechanisms immunity activation, agents can be divided into chemotherapeutic agents, immunomodulators, enzymes, vaccines oligonucleotide drugs, etc. Herein, we review MOFs-based drug delivery systems for immunotherapy. The classification MOFs, followed activation mechanisms, first introduced. Drug based with different also summarized, especially synergetic triggered loadings.
