Selective immunoglobulin M deficiency(sIgMD) is a rare form of dysgammaglobulinaemia characterized by an isolated low level of serum immunoglobulin M (IgM). It was an incidence of less than 0.03% in the general population and 1% in hospitalized patients. sIgMD may occur as a primary or secondary condition. sIgMD is much more common than primary .Hemophagocytic lymphohistiocytosis (HLH) is also a rare but potentially fatal disease of normal but overactive histiocytes and lymphocytes and can be primary or secondary, characterized by the overwhelming activation of normal T lymphocytes and macrophages, invariably leading to clinical and hematologic alterations...

BACKGROUND: We reported that high-fat diet (HFD)-induced metabolic syndrome (MetS) exacerbates lipopolysaccharide (LPS)-stimulated periodontitis and palmitate, the major saturated fatty acid in the HFD, amplified LPS-stimulated gene expression in vitro. Since CD36 is a major receptor for fatty acids, we investigated periodontal CD36 expression in mice with periodontitis and MetS, and the role of CD36 in inflammatory genes in macrophages stimulated by palmitate. METHODS: MetS and periodontitis were induced in mice by HFD and periodontal injection of LPS, respectively...

Many non-tumour host cells such as inflammatory cells, fibroblasts and endothelial cells are present in the tumour microenvironment and affect the malignant potential and chemo-resistance of the tumour cells. Macrophages and fibroblasts are the main components of infiltrating stromal cells and are referred to as tumour-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs), respectively. TAMs and CAFs are reported to be involved in tumour progression, although their functions change to those of an anti-tumour phenotype under specific conditions...

Following a central nervous system (CNS) injury, restoration of the blood-brain barrier (BBB) integrity is essential for recovering homeostasis. When this process is delayed or impeded, blood substances and cells enter the CNS parenchyma, initiating an additional inflammatory process that extends the initial injury and causes so-called secondary neuronal loss. Astrocytes and profibrotic mesenchymal cells react to the injury and migrate to the lesion site, creating a new glia limitans that restores the BBB. This process is beneficial for the resolution of the inflammation, neuronal survival and the initiation of the healing process...

Renal infiltration of inflammatory cells contributes to the pathogenesis of Lupus nephritis (LN). Current knowledge on the recruitment mechanisms relies mainly on findings in rodent models. Here, we assess various chemokine pathways in human LN by comparing urinary chemokine concentrations (in 25 patients with acute LN and in 78 lupus patients without active LN) with the expression of corresponding chemokine receptors on urinary leukocytes (in ten acute LN patients). Nine urinary chemokines were significantly elevated in LN patients and correlated with renal disease activity and urinary cell counts; however, their concentrations displayed considerable interindividual heterogeneity...

BACKGROUND: Obstructive sleep apnea (OSA) is the most common sleep disorder affecting 2-4 % of the adult population. In addition to several potential mechanisms, inflammation is one of the suggested etiological factors in OSA. Fractalkine/CX3CL1 which is detected in activated or stressed endothelium, smooth muscle cells, skeletal muscle cells, macrophages, neurons, and hepatocytes is an inflammatory marker and attracts attention of sleep specialists in OSA pathogenesis. In this study, we had two goals...

Methionine is an essential amino acid involved in critical metabolic process, and regulation of methionine flux through metabolism is important to supply this amino acid for cell needs. Elevation in plasma methionine commonly occurs due to mutations in methionine-metabolizing enzymes, such as methionine adenosyltransferase. Hypermethioninemic patients exhibit clinical manifestations, including neuronal and liver disorders involving inflammation and tissue injury, which pathophysiology is not completely established...

PURPOSE: Anti-vascular endothelial growth factor (VEGF) drugs are used to treat neovascular eye diseases. Some of these drugs contain Fc fragments (Fc), but it is unknown how their mode of action is influenced by Fc. Therefore, this study investigated the effects of Fc on rat eyes after intravitreal injection. METHODS: Eighteen Long-Evans rats were intravitreally injected with sterile, biotin-labeled rat Fc (9.1 μg in 5 μl PBS). For control, 5 μl PBS was injected in another nine rats...

CD74 (MHC class II invariant chain, Ii) is a non-polymorphic type II transmembrane glycoprotein. It is clear that, in addition to be an MHC class II chaperone, CD74 has a diversity of biological functions in physiological and pathological situations. CD74 also participates in other non-MHC II protein trafficking, such as angiotensin II type I receptor. In addition, CD74 is a cell membrane high-affinity receptor for macrophage migration inhibitory factor (MIF), D-dopachrome tautomerase (D-DT/MIF-2) and bacterial proteins...

Tissue macrophages of fetal and adult origin have pivotal roles in tissue homeostasis and organ inflammation. Recently several functional and transcriptomic studies have revealed their unique module-like transcriptomic organization leading to enormous tissue-dependent functional plasticity. In this review, we discuss the development, tissue adaption and function of resident murine and human macrophages. Finally, we discuss our limited knowledge on human tissue macrophages and provide our opinion on their relevance during disease and for clinical application...

A series of 31 pentacyclic triterpenoids isolated from the root barks of Celastrus vulcanicola and Maytenus jelskii were tested for cytotoxicity and inhibitory activity against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 macrophages. Compounds 18 (C18) and 25 (C25) exhibited significant inhibition of LPS-induced NO release at 50 and 25μM concentrations, respectively, and decreased mRNAs of pro-inflammatory cytokines. At the molecular level, C18 neither inhibited LPS-mediated phosphorylation of mitogen activated protein kinases (MAPKs) nor nuclear translocation of nuclear factor kappa beta (NFκB)...

Mycobacterium tuberculosis (M. tuberculosis) is the intracellular bacterium responsible for tuberculosis disease (TD). Inside the phagosomes of activated macrophages, M. tuberculosis is exposed to cytotoxic hydroperoxides such as hydrogen peroxide, fatty acid hydroperoxides and peroxynitrite. Thus, the characterization of the bacterial antioxidant systems could facilitate novel drug developments. In this work, we characterized the product of the gene Rv1608c from M. tuberculosis, which according to sequence homology had been annotated as a putative peroxiredoxin of the peroxiredoxin Q subfamily (PrxQ B from M...

Acute respiratory distress syndrome (ARDS) is one of the most devastating complications of sepsis lacking of effective therapy. Mitochondrial dynamics undergoing continuous fusion and fission play a crucial role in mitochondrial structure and function. Fis1, as a small protein located on the outer membrane of mitochondria, has been thought to be an important protein mediated mitochondrial fission. During ARDS, alveolar macrophages suffer from increased oxidative stress and apoptosis, and also accompanied by disrupted mitochondrial dynamics...

BACKGROUND: Neurosyphilis (NS) is difficult to diagnose, especially in syphilis patients with negative cerebrospinal fluid (CSF) rapid plasma reagin (RPR) or Venereal Disease Research Laboratory (VDRL) tests. METHODS: We conducted a cross-sectional study and an analysis of macrophage migration inhibitory factor (MIF) in syphilitic patients to identify a novel marker for the diagnosis of NS, with a focus on probable NS (NS with negative VDRL/RPR tests). For this purpose, CSF and serum MIF concentrations were determined in 43 NS and 43 syphilis/non-NS (N-NS) patients at the Zhongshan Hospital of the Medical College of Xiamen University from July 2014 to June 2015...

In vertebrates, myeloid cells arise from multiple waves of development: the first or embryonic wave of myelopoiesis initiates early from non-hematopoietic stem cell (HSC) precursors and gives rise to myeloid cells transiently during early development; whereas the second or adult wave of myelopoiesis emerges later from HSCs and produces myeloid cells continually during fetal and adult life. In the past decades, a great deal has been learnt about the development of myeloid cells from adult myelopoiesis, yet the genetic network governing embryonic myelopoiesis remains poorly defined...

Macrophages play an important role in inflammatory responses; however, miRNA-mediated repolarization of macrophages is essential for fulfilling this function. To clarify a series of changes at the RNA level in alveolar macrophages under normal and inflammatory conditions, bronchial alveolar lavage liquid (BALF) was collected from healthy volunteers or patients with pneumonia. This approach, which differs from that used in previously, provides more accurate information about the states of macrophages in different lung microenvironments...

Objective: Childhood obesity which is a predictor of adulthood obesity is associated with type 2 diabetes, metabolic syndrome, dyslipidemia, coronary artery diseases and subclinical inflammation. Growth differentiation factor-15, also known as macrophage inhibitory cytokine-1 (MIC-1/GDF15) is a member of the transforming growth factor- β super family and increases during inflammatory states. Adults with obesity have increased serum concentrations of MIC-1/GDF15. MIC-1/GDF15 is associated with cardio metabolic risk in adults...

The anti-tubercular activity of 6-chloro-2-ethyl-N-(4-(4-(4-(trifluoromethoxy)phenyl)piperidin-1-yl)benzyl)imidazo [1,2-a]pyridine-3-carboxamide (Q203) is modified by varying its side chain. In this study, we synthesized Q203 analogues with different side chains and studied their effects on anti-tubercular activity. Many analogues showed good potency against M. tuberculosis replicating in liquid broth culture medium (extracellular activity) regardless of chain length and conformational changes. However, a polar character in the side chain region was unfavorable for anti-tubercular activity...
