HIV infection markedly increases the likelihood of latent tuberculosis infection progressing to active TB. Information on expression of TLR-2, myeloid differentiation factor (MyD88), IL-1R- associated kinase-4 (IRAK4) and nuclear factor kappa B (NF-kB) in HIV+LTBI+ and HIV+ patients with active TB disease is limited. We found significantly higher percentages of CD14+TLR2+ cells in PBMCs of HIV+LTBI+ patients compared to HIV-LTBI+ individuals. γ-irradiated Mtb was unable to induce MyD88, IRAK4 expression and IL-1β, MCP-1, IP-10 production in HIV+LTBI+ patients...

Inflammation can occur via different mechanisms, such as via acute and chronic responses, on numerous occasions and function accordingly through various roles. There are more than five subsets of neutrophils; neutrophilic heterogeneity is modulated by the inflammatory condition. To understand the characteristics of inflammation, identification of atypical neutrophils is important. In this study, we found that the expression of eotaxin receptor (CD193) on atypical neutrophils in the duodenum is augmented in IL-21 isoform transgenic (Tg) mice...

Expression of GPCR fatty acid sensor/receptor genes in adipocytes is modulated by inflammatory mediators, particularly IL-1β. In this study we examined whether the IL-1 gene superfamily member, IL-33, also regulates expression of the fatty acid receptor genes in adipocytes. Human fat cells, differentiated from preadipocytes, were incubated with IL-33 at three different dose levels for 3 or 24 h and mRNA measured by qPCR. Treatment with IL-33 induced a dose-dependent increase in GPR84 mRNA at 3 h, the level with the highest dose being 13...

BACKGROUND: Interleukin (IL)-4 and IL-10 are viewed mainly as anti-inflammatory cytokines. Yet, high concentrations have also been associated with inflammation-related diseases in newborns. METHODS: We measured the concentrations of IL-4 and IL-10, as well as IL-8 and ICAM-1 in blood specimens collected on postnatal day 21 (N = 555), day 28 (N = 521), and both days 21 and 28 (N = 449) from children born extremely preterm (EP) (<28 weeks gestation) who at age 10 years had a DAS-II IQ Z-score > -2 (which approximates a score of >70) and the following assessments, CCC-2, and CSI-4, DAS-II, NEPSY-II, OWLS-II, SCQ, and WIAT-III...

BACKGROUND: The nature of a link between poor oral health and obesity is not fully understood. It is also unclear if saliva contributes to it and whether the properties of saliva change as a result of an increase in body mass or rather as a consequence of obesity-associated comorbidities. This pilot study was undertaken in an attempt to determine if salivary biomarkers can identify obesity per se. METHODS: Whole mixed saliva was analysed for 16 soluble parameters covering 4 categories (inflammation, oxidative stress, endothelial dysfunction, adipokines)...

Obesity is a serious and growing world healthy problem affecting developed and developing countries. The new conception of obesity as a basal inflammatory condition has opened a new window of possibilities to identify inflammatory biomarkers to be used in the diagnosis or prognosis of obesity-associated comorbidities. This present work aims the identification of the adipokines (leptin and resistin), chemokines (CCL2, CCL5, CXCL16) and the BMP-2 and their association with the clinical, biochemical (fasting glucose, hemogram, cholesterol, T3, T4 and TSH) and anthropometric (weight, height, body circumferences, skinfold thickness and percentage of body fat) parameters in young adults (18-30 years old) presenting obesity and overweight...

Nasopharyngeal carcinoma (NPC) is a fast-growing cancer characterized by high occurrences of nodal and distant metastases and poor prognosis. It is therefore important to identify new serum biomarkers for the early diagnosis and prognostic prediction of this disease. The present study identifies biomarkers in NPC patient serum using a solid-phase antibody array detecting the expression profiles of 174 cytokines in a single experiment. ELISA was performed to validate the array results. The levels of TIMP-2, SELL, CCL24, MMP-1, MMP-3, IGF-I and IL-8 were significantly higher in serum from NPC patients, while the levels of MSP-alpha and HCC-4 were lower...

We have previously shown that the heterodimeric cytokine interleukin-12, and the homodimer of its larger subunit p40, both bind to heparin and heparan sulfate with relatively high affinity. In the present study we characterised these interactions using a series of chemically modified heparins as competitive inhibitors. Human interleukin-12 and p40 homodimer show indistinguishable binding profiles with a panel of heparin derivatives, but that of murine interleukin-12 is distinct. Heparin markedly protects the human and murine p40 subunits, but not the p35 subunits, from cleavage by the bacterial endoprotease LysC, further implicating the larger subunit as the location of the heparin binding site...

Plasma cell mastitis (PCM) is a chronic mastitis with limited treatment options and common recurrence. A histopathological hallmark of PCM is the infiltration of numerous plasma cells surrounding the mammary duct. Our previous study showed that the activity of the IL-6/STAT3 signaling pathway was elevated in patients with PCM. However, the etiology of PCM remains largely unclear. In this study, we sought to explore the effects of IL-6/JAK2/STAT3 signaling pathway in the pathogenesis of PCM. Histological analysis showed that the mammary glands of mice that received human breast tissue homogenates, followed by an injection of IL-6, exhibited features of PCM similar to human PCM...

We have previously verified that neonatal hepatitis B vaccination induced hippocampal neuroinflammation and behavior impairments in mice. However, the exact mechanism of these effects remain unclear. In this study, we observed that neonatal hepatitis B vaccination induced an anti-inflammatory cytokine response lasting for 4-5 weeks in both the serum and the hippocampus, primarily indicated by elevated IL-4 levels. Three weeks after the vaccination schedule, however, hepatitis B vaccine (HBV)-mice showed delayed hippocampal neuroinflammation...

BACKGROUND: Tumor necrosis factor-alpha (TNF-α) are considered as a pro inflammatory and interleukin-10 (IL-10) anti inflammatory have been shown to predict the risk of incident of coronary artery disease (CAD). The polymorphism at promoter of TNF-α and IL-10 has been shown to increase transcriptional activity of the gene and play a important role in patho physiology of CAD. Aim of present study is to examine the impact of the TNF-α and IL-10 variant allele on various markers of the CAD and to study its relation with circulating TNF-α and IL-10 levels...

Melanin synthesis in melanocytes is affected by various cytokines. Here, we reported for the first time that tumor necrosis factor superfamily member 14 (TNFSF14) inhibits melanogenesis in the primary culture of human epidermal melanocytes. TNFSF14 is known to bind to its receptors herpes virus entry mediator (HVEM) and lymphotoxin β receptor (LTβR) for signal transduction, but TNFSF14-induced hypopigmentation was independent of HVEM and LTβR in melanocytes. To explore signaling in melanocytes treated with TNFSF14, we performed RNA-seq and found that nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) signaling is activated by TNFSF14...

INTRODUCTION: Despite the widely described role of IL10 in immune response regulation during carcinogenesis, there is no established model describing the role of its receptor. The aim of this study is to elucidate the relationship between the subunit alpha of IL10 receptor (IL10RA) in the pathogenesis of colorectal cancer (CRC). METHODS: The study was conducted on archived paraffin blocks of 125 CRC patients, from which tissue microarrays (TMA) were made. These were subsequently used for immunohistochemistry to assess the expression of IL10RA, IL10, phosphorylated STAT3 (pSTAT3) and the Ki67 proliferation index...

Interstitial cystitis (IC) is a chronic syndrome that affects the urinary bladder. The etiology of this disease is unclear, and no effective therapies are available at this time. Although inflammation is suspected, no clear evidence for a role of conventional mediators of inflammation, such as cytokines and their downstream molecules, has been obtained to date. Our previous studies indicated that primary cell cultures derived from IC urothelium abnormally express molecules associated with cell adhesion. Here we describe a mechanism by which transcriptional changes in tight junction and adhesion molecules are mediated...

BACKGROUND: Heart failure (HF) is characterized by impaired systolic ejection capacity and/or diastolic filling of the heart, leading to a multisystem disorder. Remote organ failure, systemic inflammation or pulmonary hypertension (PH) are hallmarks of the pathophysiological changes in HF. The Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that is involved in a variety of cardiovascular and inflammatory diseases. Circulating MIF levels and their potential role as a disease marker in the different subgroups of HF have not been investigated yet...

The pro-tumoral effects of CCL5 have been identified in numerous cancer types. We successfully cultivated 4 esophageal squamous cell carcinoma (ESCC) cell lines, including TWES-1, TWES-3 and a pair of cell lines derived from primary lesion (TWES-4PT) and metastatic lymph node (TWES-4LN) of the same patient. Whole genome screening showed that TWES-4LN expressed higher levels of CCL5 compared to that of TWES-4PT; quantification of protein secretion displayed comparable results, suggesting that CCL5 could be associated with lymph node metastasis in ESCC...

Adiponectin is considered an adipokine that has essential anti-inflammatory and insulin-sensitivity actions. The adaptor protein containing the pleckstrin homology domain, the phosphotyrosine-binding domain, and leucine zipper motif 1 (APPL1) is a protein involved in adiponectin signaling that plays a role in many physiological and pathophysiological processes. In the central nervous system, adiponectin can potentiate the effects of leptin in the arcuate proopiomelanocortin (POMC) neurons. However, the role of APPL1 in the hypothalamus is not well understood...
