AI Article Synopsis
Article Abstract
A large number of variables have been identified which appear to influence macrophage phenotype within the tumour microenvironment. These include reciprocal chemical and physical interactions with tumour cells and with non-malignant cells of the tumour microenvironment, tissue oxygen tension, and the origin and prior experience of the particular macrophage population. In this review we outline the key evidence for these influences and consider how macrophage phenotype is acquired and the relevance of the TLR-NF-kappaB pathway.

Background: Esophageal squamous cell carcinoma (ESCC) is one of the most prevalent and lethal malignancies worldwide. Despite progress in immunotherapy for cancer treatment, its application and efficacy in ESCC remain limited. Therefore, there is an ongoing need to explore potential molecules and therapeutic strategies related to tumor immunity in ESCC.

We have previously demonstrated that DEC1 promotes osteoblast differentiation. This study aims to evaluate the impact of DEC1 knockout on osteopenic activities, such as osteoclast differentiation and the expression of bone-degrading genes. To gain mechanistic insights, we employed both in vivo and in vitro experiments, utilizing cellular and molecular approaches, including osteoclast differentiation assays and RNA-seq in combination with ChIP-seq.

Aberrant sialylated glycosylation in the tumor microenvironment is a novel immune suppression pathway, which has garnered significant attention as a targetable glycoimmune checkpoint for cancer immunotherapy to address the dilemma of existing therapies. However, rational drug design and in-depth mechanistic studies are urgently required for tumor sialic acid to become valuable glycoimmune targets. In this study, we explored the positive correlation of PD-L1 and sialyltransferase expression in clinical colorectal cancer tissues and identified their mutual regulation effects in macrophages.

The peritoneal cavity (PerC) is a discrete anatomical compartment housing diverse peritoneal macrophage subpopulations. Nonetheless, there exists a paucity of knowledge concerning the distinct functions of these subpopulations in the context of hepatocellular carcinoma (HCC) and their evolution throughout tumor advancement. This investigation seeks to analyze the characteristics of two principal peritoneal macrophage subpopulations, specifically large peritoneal macrophage (LPM) and small peritoneal macrophage (SPM), in the context of HCC.

The immunomodulatory properties of hyaluronan and its derivatives are key to their use in medicine and tissue engineering. In this work we evaluated the capability of soluble tyramine-modified hyaluronan (THA) synthesized from hyaluronan of two molecular weights (low M = 280 kDa and high M = 1640 kDa) for polarization of THP-1 and peripheral blood mononuclear cells (PBMCs)-derived macrophages (MΦs). We demonstrate the polarization effects of the supplemented THA by flow cytometry and bead-based multiplex immunoassay for the THP-1 derived MΦs and by semi-automated image analysis from confocal microscopy, immunofluorescent staining utilizing CD68 and CD206 surface markers, RT-qPCR gene expression analysis, as well as using the enzyme-linked immunosorbent assay (ELISA) for PBMCs-derived MΦs.
