Deep RNA Sequencing Uncovers a Repertoire of Human Macrophage Long Intergenic Noncoding RNAs Modulated by Macrophage Activation and Associated With Cardiometabolic Diseases

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundSustained and dysfunctional macrophage activation promotes inflammatory cardiometabolic disorders, but the role of long intergenic noncoding RNA (lincRNA) in human macrophage activation and cardiometabolic disorders is poorly defined.

Modulation of macrophage activation by prostaglandins [PDF]

Mediators of Inflammation, 1996
The effect of prostaglandtn E2, iloprost and cAMP on both nitric oxide and tumour necrosis factor‐α release in J774 macrophages has been studied. Both prostaglandin E2 and iloprost inhibited, in a concentration‐dependent fashion, the lipopolysaccharide‐induced generation of nitric oxide and tumour necrosis factor‐α.

The liver X receptor pathway is highly upregulated in rheumatoid arthritis synovial macrophages and potentiates TLR-driven cytokine release [PDF]

, 2013
<p>Objectives: Macrophages are central to the inflammatory processes driving rheumatoid arthritis (RA) synovitis. The molecular pathways that are induced in synovial macrophages and thereby promote RA disease pathology remain poorly understood.</

α1-nAchR-Mediated Signaling Through Lipid Raft Is Required for Nicotine-Induced NLRP3 Inflammasome Activation and Nicotine-Accelerated Atherosclerosis

Frontiers in Cell and Developmental Biology, 2021
BackgroundNicotine exerts direct effects on multiple cell types in the cardiovascular system by associating with its high-affinity nicotinic acetylcholine receptors (nAchRs).

Activation of GPER1 in macrophages ameliorates UUO-induced renal fibrosis

Cell Death and Disease, 2023
Numerous studies have proven the critical role of macrophages in the renal fibrosis process. Notably, G Protein-coupled Estrogen Receptor 1 (GPER1), a novel estrogen receptor, has been shown to play a ubiquitous role in regulating macrophage activities ...

Lipase Activity in Leukocytes and Macrophages [PDF]

Blood, 1964
Abstract A method is described for the quantitative determination of alkaline lipase activity of blood cells. The pH optimum of the enzyme in macrophages and lymphocytes from patients with chronic lymph-leukemia is 9.2, the optimum substrate (triglyceride) concentration is 7 x 10-2 M, and the Michaelis constant approximately 4.3 x 10-2 M.

Hepatocyte mitochondrial DNA mediates macrophage immune response in liver injury induced by trichloroethylene

Ecotoxicology and Environmental Safety
We have previously shown that excessive activation of macrophage proinflammatory activity plays a key role in TCE-induced immune liver injury, but the mechanism of polarization is unclear. Recent studies have shown that TLR9 activation plays an important

Macrophage Activation Marker Soluble CD163 Associated with Fatal and Severe Ebola Virus Disease in Humans

Emerging Infectious Diseases, 2019
Ebola virus disease (EVD) is associated with elevated cytokine levels, and hypercytokinemia is more pronounced in fatal cases. This type of hyperinflammatory state is reminiscent of 2 rheumatologic disorders known as macrophage activation syndrome and ...

The nuclear receptor LXRα controls the functional specialization of splenic macrophages. [PDF]

, 2013
Macrophages are professional phagocytic cells that orchestrate innate immune responses and have considerable phenotypic diversity at different anatomical locations. However, the mechanisms that control the heterogeneity of tissue macrophages are not well
