Abstract Tumorigenesis is a multistep process, with oncogenic mutations in normal cell conferring clonal advantage as the initial event. However, despite pervasive somatic and expansion tissues, their transformation into cancer remains rare event, indicating presence of additional driver events for progression to an irreversible, highly heterogeneous, invasive lesion. Recently, researchers are emphasizing mechanisms environmental tumor risk factors epigenetic alterations that profoundly influencing early malignant evolution, independently inducing mutations. Additionally, evolution tumorigenesis reflects multifaceted interplay between cell-intrinsic identities various cell-extrinsic exert selective pressures either restrain uncontrolled proliferation or allow specific clones progress tumors. by which induce both intrinsic cellular competency remodel stress facilitate not fully understood.

Abstract Macrophages infiltrating tumour tissues or residing in the microenvironment of solid tumours are known as tumour-associated macrophages (TAMs). These specialized immune cells play crucial roles growth, angiogenesis, regulation, metastasis, and chemoresistance. TAMs encompass various subpopulations, primarily classified into M1 M2 subtypes based on their differentiation activities. macrophages, characterized by a pro-inflammatory phenotype, exert anti-tumoural effects, while with an anti-inflammatory function protumoural regulators. highly versatile respond to stimuli from other constituents within (TME), such growth factors, cytokines, chemokines, enzymes. induce polarization towards one phenotype another, leading complex interactions TME components influencing both pro-tumour anti-tumour processes.

The tumor microenvironment (TME) is a combination of cells and indigenous host stroma, which consists tumor-infiltrating immune cells, endothelial fibroblasts, pericytes, non-cellular elements. Tumor-associated macrophages (TAMs) represent the major cell type are generally polarized into two functionally contradictory subtypes, namely classical activated M1 alternatively M2 macrophages. Macrophage polarization refers to how at given time space. interplay between TME macrophage can influence initiation progression, making TAM potential target for cancer therapy. Here, we review latest investigations on factors orchestrating in TME, affects perspectives modulating immunotherapy.

Abstract Tumor-associated macrophages (TAMs) are pivotal in cancer progression, influencing tumor growth, angiogenesis, and immune evasion. This review explores the spatial temporal heterogeneity of TAMs within microenvironment (TME), highlighting their diverse subtypes, origins, functions. Advanced technologies such as single-cell sequencing multi-omics have elucidated intricate interactions between other TME components, revealing mechanisms behind recruitment, polarization, distribution. Key findings demonstrate that support vascularization, promote epithelial-mesenchymal transition (EMT), modulate extracellular matrix (ECM) remodeling, etc., thereby enhancing invasiveness metastasis. Understanding these complex dynamics offers new therapeutic targets for disrupting TAM-mediated pathways overcoming drug resistance. underscores potential targeting to develop innovative therapies, emphasizing need further research into characteristics functional roles TME.
