Glioblastoma multiforme (GBM) is the most lethal and aggressive type of primary brain malignancy. Failures of the traditional therapies in treating GBMs raise the urgent requirement to develop new approaches with more responsive targets. The phenomenon of the high infiltration of tumor-associated macrophages (TAMs) into GBMs has been observed for a long time. Regardless of the limited knowledge...

Macrophages are cells of the innate immune system that respond to external stimuli by rapidly adapting their transcriptional programs and behavior. Upon exposure to inflammatory signals or pathogen-associated molecules, macrophages activate a proinflammatory program (called “classical” or M1 activation) that enhances their direct microbicidal functions and, arguably, their ability to stimulate ...

Tumour-associated macrophages (TAMs) represent pivotal components of tumour microenvironment promoting angiogenesis, tumour progression and invasion. In colorectal cancer (CRC), there are no conclusive data about the role of TAMs in angiogenesis-mediated tumour progression. In this study, we aimed to evaluate a correlation between TAMs, TAM immunostained area (TAMIA) microvascular density (MVD)...

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...
