BACKGROUND Triple-negative breast cancer (TNBC) is associated with poor prognosis and high probability of distant metastases. Tumor microenvironments play a pivotal role in tumor metastasis. Tumor-associated macrophages (TAMs) are one of the main cell components, and they are correlated with increasing metastatic risk. The aim of this study is to analyze the prognostic significance of the infil...
Tumor-associated macrophages (TAMs) are a major cellular component in the tumor microenvironment of many solid tumors. The functional competence of TAMs varies depending on the type of tumors and their respective microenvironments. The classically activated M1 macrophages exhibit antitumor functions, whereas the alternatively activated M2 macrophages exhibit protumor functions that contribute t...
Macrophages are prominent in the stromal compartment of virtually all types of malignancy. These highly versatile cells respond to the presence of stimuli in different parts of tumors with the release of a distinct repertoire of growth factors, cytokines, chemokines, and enzymes that regulate tumor growth, angiogenesis, invasion, and/or metastasis. The distinct microenvironments where tumor-ass...
Tumor associated macrophages (TAMs) play a critical role in solid tumor development where they regulate neoplastic cell proliferation , survival and invasion, promote angiogenesis, and impact effector functions of T cells (1). Typically, TAMs activated by toll-like receptor (TLR) signaling or interferon (IFN)-γ are considered classically activated or Th1-type cells, whereas those activated by i...
BACKGROUND HIV-1 drug resistance to older thymidine analogue nucleoside reverse transcriptase inhibitor drugs has been identified in sub-Saharan Africa in patients with virological failure of first-line combination antiretroviral therapy (ART) containing the modern nucleoside reverse transcriptase inhibitor tenofovir. We aimed to investigate the prevalence and correlates of thymidine analogue m...
Macrophages are essential components of the inflammatory microenvironment of tumors. Conventional treatment modalities (chemotherapy and radiotherapy), targeted drugs, antiangiogenic agents, and immunotherapy, including checkpoint blockade, all profoundly influence or depend on the function of tumor-associated macrophages (TAMs). Chemotherapy and radiotherapy can have dual influences on TAMs in...
Background/Aim: The tumor microenvironment plays an important role in progression. Tumor-associated macrophages (TAMs) have been reported to promote proliferation, invasion, metastasis, angiogenesis, and immunosuppression. Furthermore, angiogenesis has induce chemoresistance due the inefficient distribution of drugs cancer cells. However, impact TAMs on via colorectal (CRC) remains unclear. aim...
Tumor-associated monocytic cells (TAMs) are a major component of the stroma responsible for tumor formation. TAMs generate various kinds of mediators for their function, one of which is thymidine phosphorylase (TP). TP is an angiogenic enzyme that is known to be up-regulated in tumor tissues. Here, we focused on the clinical implication of TP expression in TAMs by studying 229 primary breast ca...
Tumor-associated macrophages (TAMs) are essential cellular components within tumor microenvironment (TME). TAMs are educated by TME to transform to M2 polarized population, showing a M2-like phenotype, IL-10(high), IL-12(low), TGF-β(high). STAT3 signaling triggers crosstalk between tumor cells and TAMs, and is crucial for the regulation of malignant progression. In our study, legumain-targeting...
Tumor vascularization is a highly complex process that involves the interaction between tumors and their surrounding stroma, as well as many distinct angiogenesis-regulating factors. Tumor associated macrophages (TAMs) represent one of the most abundant cell components in the tumor environment and key contributors to cancer-related inflammation. A large body of evidence supports the notion that...
