Hao Wu et al.
Autophagy, 15(11), 1882-1898 (2019-03-23)
There is overwhelming evidence for an association between impaired mitochondrial function and metabolic syndrome. Mitophagy, a process that selectively removes damaged mitochondria via a specialized form of autophagy, is essential for mitochondrial quality control (mitochondrial QC) and metabolic homeostasis. We

Class B scavenger receptors (SR-Bs) bind lipoproteins and play an important role in lipid metabolism. Most recently, SR-B type I (SR-BI) and its splicing variant SR-BII have been found to mediate bacterial adhesion and cytosolic bacterial invasion in mammalian cells.

Critical care (London, England), 14(6), R201-R201 (2010-11-10)
This study was carried out to determine whether interactions of cell activation, shear stress and platelets at sites of endothelial injury explain the paradoxical maldistribution of activated leukocytes during sepsis away from local sites of infection towards disseminated leukocyte accumulation
Yi Xu et al.
American journal of reproductive immunology (New York, N.Y. : 1989), 64(2), 137-151 (2010-06-22)
Emerging evidence suggests that metabolism influences immune cell signaling and immunoregulation. To examine the immunoregulatory role of glycolysis in pregnancy, we evaluated the properties of pyruvate kinase in leukocytes from non-pregnant women and those with normal pregnancy and pre-eclampsia. We

Microbial cell factories, 7, 22-22 (2008-07-30)
Chemokines are a large group of chemotactic cytokines that regulate and direct migration of leukocytes, activate inflammatory responses, and are involved in many other functions including regulation of tumor development. Interferon-gamma inducible-protein-10 (IP-10) is a member of the C-X-C subfamily
Jian Liang et al.
PloS one, 3(8), e2880-e2880 (2008-08-07)
Previously, we have identified a novel CCCH zinc finger protein family as negative regulators of macrophage activation. To gain an overall insight into the entire CCCH zinc finger gene family and to evaluate their potential role in macrophage activation, here

One of the limiting factors in tissue regeneration, particularly in the context of chronic disease such as myodystrophy, motor neuron disease, sarcopenia, and cardiovascular disease, is limited availability of stem cells. We propose employing autologous macrophages to deliver stem cells
Sverre Holm et al.
PloS one, 6(12), e28785-e28785 (2011-12-17)
Fatty acid binding protein 4 (FABP4) has been shown to play an important role in macrophage cholesterol trafficking and associated inflammation. To further elucidate the role of FABP4 in atherogenesis in humans, we examined the regulation of FABP4 in carotid
Huimin Yan et al.
Arteriosclerosis, thrombosis, and vascular biology, 36(8), 1660-1669 (2016-06-11)
We previously established that neutrophil-derived dipeptidyl peptidase I (DPPI) is essential for experimental abdominal aortic aneurysm (AAA) development. Because DPPI activates several neutrophil serine proteases, it remains to be determined whether the AAA-promoting effect of DPPI is mediated by neutrophil
Paula Bertram et al.

The complement alternative pathway (AP) is a major contributor to a broad and growing spectrum of diseases that includes age-related macular degeneration, atypical hemolytic uremic syndrome, and preeclampsia. As a result, there is much interest in the therapeutic disruption of
Francisco Azuaje et al.
Theoretical biology & medical modelling, 8, 7-7 (2011-04-12)
We investigated an algorithmic approach to modelling angiogenesis controlled by vascular endothelial growth factor (VEGF), the anti-angiogenic soluble VEGF receptor 1 (sVEGFR-1) and adenosine (Ado). We explored its feasibility to test angiogenesis-relevant hypotheses. We illustrated its potential to investigate the
Daniel Blumenthal et al.
eLife, 9 (2020-07-29)
T cell activation by dendritic cells (DCs) involves forces exerted by the T cell actin cytoskeleton, which are opposed by the cortical cytoskeleton of the interacting antigen-presenting cell. During an immune response, DCs undergo a maturation process that optimizes their
Zul'atfi Rahmat et al.
Stem cell research & therapy, 4(1), 12-12 (2013-01-30)
Mesenchymal stem cells (MSCs) are immunosuppressive, but we lack an understanding of how these adult stem cells are in turn affected by immune cells and the surrounding tissue environment. As MSCs have stromal functions and exhibit great plasticity, the influence
Randy Tatt Yhew Haw et al.
Journal of neuroinflammation, 11, 134-134 (2014-07-31)
We report a novel method of culturing microglia in three dimension (3D) using collagen as a substrate. By culturing microglia within a matrix, we aim to emulate the physical state of microglia embedded within parenchyma. BV2 microglia cell suspensions were
Xiangliang Zeng et al.
Neurotoxicity research, 38(3), 785-792 (2020-07-12)
Injury associated with neuroinflammation has been linked with several kinds of neurodegenerative diseases. The activation of the NLRP3 inflammasome plays an important role in microglia-mediated inflammation. Phoenixin (PNX)-20 is a newly discovered neuropeptide with pleiotropic effects involved in the regulation
Bernhard Schaaf et al.
Diagnostic pathology, 4, 12-12 (2009-04-18)
Pattern recognition receptors are a key component of the first line host defense against infection, recognizing specific microbial products. We hypothesize that monocyte hyporesponsiveness in human sepsis is associated with a downregulation of the pattern recognition receptors Toll-like receptor (TLR)-2
Yingqian Huo et al.
BMC neuroscience, 12, 49-49 (2011-05-28)
Nox-2 (also known as gp91phox), a subunit component of NADPH oxidases, generates reactive oxygen species (ROS). Nox-dependent ROS generation and nitric oxide (NO) release by microglia have been implicated in a variety of diseases in the central nervous system. Dexamethasone

Immunology, 127(1), 91-102 (2008-09-10)
Anti-ribosomal phosphoprotein autoantibodies have been shown to be significantly associated with multiple manifestations of systemic lupus erythematosus (SLE). High levels of interleukin-10 (IL-10) have been demonstrated to contribute to lupus susceptibility and severity. In this study, we investigated the molecular

Proceedings of the National Academy of Sciences of the United States of America, 106(8), 2735-2740 (2009-02-06)
In response to inflammatory stimulation, dendritic cells (DCs) have a remarkable pattern of differentiation (maturation) that exhibits specific mechanisms to control immunity. Here, we show that in response to Lipopolysaccharides (LPS), several microRNAs (miRNAs) are regulated in human monocyte-derived dendritic
