Pentraxin3 (PTX3), a member of long pentraxin family, plays a non-redundant role in human humoral innate immunity. However, whether PTX3 is expressed by corneal epithelial cells and its role during corneal fungi infection has not yet been investigated. To identify the presence of PTX3 in cornea, the possible mechanisms involved in its expression, and also the effects on corneal anti-fungi innate immune response, clinic human corneal tissues and cultured human corneal epithelial cells (HCECs) were resorted. PTX3 mRNA and protein were detected in corneal samples and cultured HCECs, which was significantly up-regulated after exposing to Aspergillus fumigatus (A...

BACKGROUND: Cytokines and chemokines in the tumor microenvironment drive metastatic development and their serum levels might mirror the ongoing inflammatory reaction at the tumor site. Novel highly sensitive tools are needed to identify colorectal cancer patients at high risk of recurrence that should be more closely monitored during post-surgical follow up. Here we study whether circulating inflammatory markers might be used to predict recurrence in CRC patients. METHODS: Circulating levels of the inflammatory cytokines IL-1, IL-6, IL-10, TNFalpha, CCL2, CXCL8, VEGF and the acute phase protein Pentraxin-3 were measured by ELISA in preoperative serum samples prospectively collected from a cohort of sixty-nine patients undergoing surgical resection for stage 0-IV CRC and associated with post-operative disease recurrence...

The role of pentraxin 3 (PTX3) has been implicated in the process of plaque vulnerability. However, few studies have addressed the direct relationship between plaque morphology and plasma PTX3. We evaluated the relationship between coronary vulnerable plaque, assessed by optical coherence tomography (OCT), and plasma PTX3 in patients with coronary artery disease (CAD).OCT was used to determine plaque vulnerability in 51 patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS; n = 17) and stable angina (SA; n = 34)...

BACKGROUND: Long pentraxin 3 (PTX3) is a novel candidate marker for inflammation in many chronic diseases. As a soluble pattern recognition receptor, PTX3 is involved in amplification of inflammatory reactions and regulation of innate immunity. Previously, we demonstrate that human airway smooth muscle cells (HASMC) express constitutively PTX3 and upon TNF stimulation. However, very little is known about the mechanism governing its expression in HASMC. We sought to investigate the mechanism governing TNF induced PTX3 expression in primary HASMC...

Cardiomyocyte death as a result of viral infection is an excellent model for dissecting the inflammatory stress response that occurs in heart tissue. We reported earlier that a specific proteasome isoform, the immunoproteasome, prevents exacerbation of coxsackievirus B3 (CVB3)-induced myocardial destruction and preserves cell vitality in heart tissue inflammation. Following the aim to decipher molecular targets of immunoproteasome-dependent proteolysis, we investigated the function and regulation of the soluble PRR Pentraxin3 (PTX3)...

BACKGROUND: Earlobe creases (ELC) are frequently observed in patients with atherosclerosis. Atherosclerosis is considered to be a systemic vascular inflammatory disease, and oxidative stress is known to be a contributor to vascular inflammation. It is well known that inflammatory biomarkers [high-sensitivity C-reactive protein (hs-CRP), pentraxin3 (PTX3)] and oxidative stress markers [malondialdehyde low-density lipoprotein (MDA-LDL)] are associated with atherosclerotic changes. This study was designed to test the hypothesis that biomarkers of inflammation and oxidative stress are increased in patients with ELC...

Hyperlipidemia is characterized by abnormally increased plasma of any or all lipids and /or lipoproteins and is a confirmed risk factor for the formation of atherosclerosis. Inflammation plays a crucial role in the formation and progression of atherosclerosis and consequently on cardiovascular diseases. Nowadays, the effective role of the immune system and subsequently of systemic inflammation is well established. Multiple levels of evidence from experimental models and histopathologic assessment of tissues to systemic biomarkers and epidemiologic or clinical associations have revealed that inflammation is one of the basic mechanisms in the destabilization of the atherogenetic plaque which leads to clinical events...

The innate immunity is the first defense reaction against microorganisms or altered self-components upon tissue injury. Such exogenous or modified endogenous molecules present conserved molecular structures that are recognized by the immune system via pattern-recognition receptors or molecules. Within the soluble pattern-recognition molecules pentraxins play an important role in humoral innate immunity. Pentraxins branch off into the short and long pentraxins. Short constituents include C-reactive protein (CRP) and serum amyloid P-component which are synthesized in the liver mostly upon IL-6 stimulation...

This study investigated morning levels of pentraxin3 (PTX3) as a sensitive biomarker for acute inflammation in patients with obstructive sleep apnea (OSA). A total of 61 consecutive patients with OSA were divided into two groups: non-to-mild (n = 20) and moderate-to-severe (n = 41) OSA based on their apnea-hypopnea index (AHI) score. Those patients with moderate-to-severe OSA were further divided into continuous positive airway pressure (CPAP) treated (n = 21) and non-CPAP-treated (n = 20) groups. Morning and evening serum PTX3 and high-sensitivity (hs) C-reactive protein (CRP) levels were measured before and after 3 mo of CPAP therapy...

BACKGROUND: The objective of this study was to determine the effects of pentraxin3 (PTX3) on human oxidized low density lipoprotein (oxLDL) uptake and cholesterol efflux from human macrophage foam cells, which may play a critical role in atherogenesis. METHODS: The effects of PTX3 on oxLDL uptake and cholesterol efflux were determined after transfection of human THP-1 macrophages with pSG5hPTX3 or PTX3siRNA plasmids. To evaluate the role of specific signaling pathways, human THP-1 cells were pre-treated with inhibitors of the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2), phosphatidylinositide 3-kinases (PI3-K), and p38 mitogen-activated protein kinase (MAPK) pathways (PD98059, LY294002, and SB203580, respectively), and then exposed to oxLDL for the uptake assay or oxLDL and [(3)H]-cholesterol and apolipoprotein A-I (apoA-I) for the cholesterol efflux assay...
