Background and Hypothesis: Tumor-associated macrophages (TAMs) are a key component of tumor-infiltrating immune cells. They largely characterized into M1 or M2 types. TAMs express an anti-inflammatory M2-like phenotype, promote tumor progression. However, the role M2-TAMs in driving disease pathogenesis patients with Juvenile myelomonocytic leukemia (JMML), rare form pediatric driven to large e...

Cancer development and progression is linked to tumor-associated macrophages (TAMs). Distinct TAMs subsets perform either protective or pathogenic effects in cancer. A protective role in carcinogenesis has been described for M1 macrophages, which activate antitumor mechanisms. By comparison, TAMs isolated from solid and metastatic tumors have a suppressive M2-like phenotype, which could support...

Results from 2 placebo-controlled intensification trials of tenofovir disoproxil fumarate (DF) in treatment-experienced human immunodeficiency type 1 (HIV-1)-infected patients (n=332) were integrated to determine the effects of resistance at baseline on HIV-1 RNA response. In these trials, there was a high prevalence of HIV-1 resistance mutations, with 94% of patients having nucleoside-associat...

We previously showed that Tie2-expressing monocytes (TEMs) have nonredundant proangiogenic activity in tumors. Here, we compared the gene expression profile of tumor-infiltrating TEMs with that of tumor-associated macrophages (TAMs), spleen-derived Gr1(+)Cd11b(+) neutrophils/myeloid-derived suppressor cells, circulating "inflammatory" and "resident" monocytes, and tumor-derived endothelial cell...

Selenium Nanoparticle (SeNPs) is reported that it enhances and maintains optimal immune during infection and malignancies. To this end, we examined the role of selenium on TAMS whose anti-tumor function suppressed which favor tumor progression. BALB/c (H2d) strain of mice non-Hodgkin type of Dalton's cell line was used to check the role of carboxlic group induced, synthesized SeNPs on TAMs. Scr...

Marine diatoms in tillites along the Transantarctic Mountains (TAMs) have been used to suggest a diminished East Antarctic Ice Sheet (EAIS) during Pliocene warm periods. Updated ice-sheet modelling shows significant Pliocene EAIS retreat, creating marine embayments into the Wilkes and Aurora basins that were conducive to high diatom productivity and rapid accumulation of diatomaceous sediments....

It is becoming increasingly clear that interactions between cancer cells, stroma cells and the extracellular matrix (ECM) are pivotal to the processes of neovascularization and tumorigenesis. As tumor stromal components known as tumor associated macrophages (TAMs), mononuclear phagocytes can play a key role in tumor type specific neoangiogenesis by promoting remodeling of the ECM through the pr...

Signalling molecules and pathways that mediate crosstalk between various tumour cellular compartments in cancer metastasis remain largely unknown. We report a mechanism of the interaction between perivascular cells and tumour-associated macrophages (TAMs) in promoting metastasis through the IL-33-ST2-dependent pathway in xenograft mouse models of cancer. IL-33 is the highest upregulated gene th...

Metabolic reprogramming in stromal cells plays an essential role in regulating tumour growth. The metabolic activities of tumour-associated macrophages (TAMs) in colorectal cancer (CRC) are incompletely characterized. Here, we identify TAM-derived factors and their roles in the development of CRC. We demonstrate that ABHD5, a lipolytic co-activator, is ectopically expressed in CRC-associated ma...
