OBJECTIVE This study aims to investigate the characteristics of liver X receptor α (LXRα) and its target gene expression, as well as cholesterol efflux in human macrophages treated by nicotine. METHODS Human monocyte-derived macrophages were collected. Before apoA-I-mediated human monocyte-derived macrophage cholesterol efflux, and mRNA expression of LXRα, and some of its target genes being d...
Objective: To determine whether global reduction of CD68 (cluster differentiation) macrophages impacts the development experimental pulmonary arterial hypertension (PAH) and this affects balance pro- anti-inflammatory within lung. Additionally, to there is evidence an altered macrophage polarization in patients with PAH. Approach Results: Macrophage was induced mice via doxycycline-induced CD68...
The low-density lipoprotein receptor-related protein (LRP) is a multifunctional receptor that binds to apolipoprotein E-rich lipoproteins, lipoprotein lipase, alpha 2-macroglobulin, lactoferrin, and tissue plasminogen activator. We studied the mRNA expression of LRP in human monocyte-derived macrophages and THP-1 cells. mRNA expression of LRP was induced during cell differentiation from human m...
BACKGROUND Low-density lipoprotein (LDL) uptake by monocyte-derived macrophages is a crucial step in foam cell formation and early atherosclerotic lesion. Increasing evidence supports the theory that activation of protein kinase Cbeta (PKCbeta) is involved in many mechanisms promoting atherosclerosis. Thus, we investigated whether inhibition of PKCbeta prevents foam cell formation. METHODS AN...
background: Classical macrophages (M1) and alternative macrophages (M2) are responsible for various functions in order to maintain homeostasis. BCG vaccine and hydatid cyst fluid can be examples of stimulants which can cause M1and M2 macrophage polarization. Evaluating the expression of markers such as IFNγ and TNFα for M1 phenotype and TGFβ and IL4 for M2 phenotype is one of the confirmatory w...
BACKGROUND In this study, we have analyzed the response of human monocyte-derived macrophages to mineralocorticoid axis modulators. METHODS Human monocyte-derived macrophages were incubated with aldosterone alone, eplerenone alone, and the combination of aldosterone and eplerenone. The analyzed variables were nitric oxide and reactive oxygen species production, and the gene and protein expres...
The mechanistic basis for why inflammation is simultaneously both deleterious and essential for tissue repair is not fully understood. Recently, a new paradigm has emerged: Organs are replete with resident macrophages of embryonic origin distinct from monocyte-derived macrophages. This added complexity raises the question of whether distinct immune cells drive inflammatory and reparative activi...
human peripheral blood monocytes have been found to undergo a transitory state of high accessory activity before they fully become macrophages. time kinetics were done to follow this accessory potential. studying the regulation of accessory activity, we have found that monocyte derived accessory cells (m-ac) pass through two phases of development, both of which are adversely controlled by cycli...
Tissue macrophages are derived exclusively from blood monocytes, which as monocyte-derived macrophages support HIV-1 replication. However, among human tissue macrophages only intestinal macrophages are non-permissive to HIV-1, suggesting that the unique microenvironment in human intestinal mucosa renders lamina propria macrophages non-permissive to HIV-1. We investigated this hypothesis using b...
