Background: Evidence indicates that neuropathic pain pathogenesis is not confined to changes in the activity of neuronal systems but involves interactions between neurons, inflammatory immune and immune-like glial cells. Substances released from immune cells during inflammation play an important role in development and maintenance of neuropathic pain. It has been found that minocycline suppress...

Macrophages can be reprogramming, such as the classical activated macrophage, M1 or alternative activated macrophages, M2 phenotype following the milieu danger signals, especially inflammatory factors. Macrophage reprogramming is now considered as a key determinant of disease development and/or regression. Experimental autoimmune myocarditis (EAM) is characterized by monocytes/macrophage infilt...

background recent studies revealed that tumor-associated macrophages (tams) play a decisive role in the regulation of tumor progression by manipulating tumor oncogenesis, angiogenesis and immune functions within tumor microenvironments. signal transducer and activator of transcription 3 (stat3), which is a point of convergence for numerous oncogenic signalling pathways, is constitutively activa...

BACKGROUND Recent observations associate plaque instability with expansive arterial remodeling, suggesting a common driving mechanism. METHODS AND RESULTS To demonstrate that macrophages, a characteristic of vulnerable plaques, also assist in expansive remodeling, we compared carotid artery remodeling due to formation of experimental macrophage-rich and macrophage-poor lesions in the flow ces...

The interactions were analyzed between actin, myosin, and a recently discovered high molecular weight actin-binding protein (Hartwig, J. H., and Stossel, T. P. (1975) J. Biol Chem.250,5696-5705) of rabbit alveolar macrophages. Purified rabbit alveolar macrophage or rabbit skeletal muscle F-actins did not activate the Mg2+ATPase activity of purified rabbit alveolar macrophage myosin unless an ad...

Introduction. Adult-onset Still?s disease is a rare inflammatory disorder of unknown etiology. It can be complicated by macrophage activation syndrome, potentially life-threatening condition. While syndrome and adult-onset share similar features, early recognition very difficult in clinical praxis. Case outline. We report young woman, whose illness was presented suddenly, with spiking fever, so...

Abstract The distinct immune landscape of glioblastoma (GBM) from other cancer is an obstacle to GBM treatment. To overcome the limited efficacy therapy, identifying interaction between tumor and infiltrated cells needed. function B against tumors recently focused on understand microenvironments. However, there are still few studies in glioblastoma. Here, we identify cell population deficient m...

OBJECTIVE Our recent studies have highlighted membrane type-1 matrix metalloproteinase (MMP)-14 as a selective marker for an invasive subset of macrophages potentially related to atherosclerotic plaque progression. Moreover, colony stimulating factors (CSF) may exert divergent effects on macrophage MMP expression, possibly through microRNAs. We, therefore, aim to identify and test the pathophys...

Hemopoietic colony-forming cells committed to macrophage differentiation (M-CFC) are selectively and differentially inhibited by prostaglandin E (PGE). A hierarchy of sensitivity was observed among murine CFC stimulated by colony-stimulating factors (CSF) which differ in their ability to initiate proliferation of morphologically distinct colony types, or stimulated by CSF provided by macrophage...

The macrophage is exquisitely sensitive to its microenvironment, as demonstrated primarily through in vitro study. Changes in macrophage phenotype and function within the atherosclerotic plaque have profound consequences for plaque biology, including rupture and arterial thrombosis leading to clinical events such as myocardial infarction. We review the evidence for dynamic changes in macrophage...
