“Candida spp. biofilms can be established on a wide range of materials, including implanted medical devices, and can display a resistant phenotype to antifungal drugs. Several factors, including host and surface properties, may influence Estrogen antagonist the

establishment and the development of Candida albicans biofilms on biotic and abiotic surfaces. We therefore selected a collection of C. albicans clinical isolates to evaluate the effect of surface and serum on biofilm attachment and development. Disc coupons from the CDC biofilm reactor were used in a well plate assay to study biofilm production on six different surfaces with or without the addition of serum: polycarbonate, polystyrene, stainless steel, Teflon, polyvinyl chloride or hydroxyapatite. Our results showed that serum increases in vitro BEZ235 concentration C. albicans biofilm formation on a wide range of distinct surfaces including metallic and non-metallic materials, and that roughness and hydrophobicity can modulate C. albicans biofilm formation. These findings were also confirmed by scanning electron

microscopy and it revealed the deposition of extracellular material on hyphae attached to a solid surface. Interestingly, adhesion can be significantly increased in the early stages of colonisation when serum is provided as a conditioning film in a surface-dependent manner. “
“Trichophyton verrucosum is the most common ringworm agent in cattle. Epidemiology of

cattle dermatophytoses in Central Italy is not clear. Its diffusion among cattle and herdsmen was investigated in 20 Umbrian Anidulafungin (LY303366) farms, Central Italy. Hairs and scales were taken from 395 animals and 31 workers. Typical ringworm was present in 71.7% of cattle under 6 months and in 11% of animals over 6 months. T. verrucosum was isolated from 98.9% of symptomatic heads and was the most prevalent dermatophyte in all herds investigated (isolated in 18 of the 20 farms). T. mentagrophytes var. mentagrophytes was found in 16 symptomatic and in eight asymptomatic young animals. Prevalence of asymptomatic carriers of both species was significantly higher in young heads (21.1% vs. 8.1%) and the age below 6 months was the only statistically significant risk factor associated with dermatophytosis. About the workers, all the 14 men with lesions were positive for T. verrucosum; copresence of T. verrucosum and Microsporum gypseum was noticed in one case. Results indicate a high diffusion of T. verrucosum among both animals and humans in Umbrian farms and confirm the dermatophyte infection as a public health problem.

Consequently, it would appear that monocyte synthesis

Consequently, it would appear that monocyte synthesis Regorafenib clinical trial of IL-10, in response to TG, is under

direct control of TG-specific cells within the T-cell population. The primary purpose of this study was to determine whether human T cells, responding to in vitro challenge with the autoantigen TG, do so as naive or antigen-experienced cells. Furthermore, it was of interest to establish whether their stimulation results in a pro-inflammatory or an anti-inflammatory cytokine response, indicating inductive or protective roles, respectively, in the development of autoimmunity. The CD4+ T-cell proliferative responses to TG and TT resembled each other closely, whereas CD4+ T-cell proliferation in response to KLH was delayed by approximately 2 days. Given that the kinetics of the TT and KLH responses are typical for memory and naive lymphocytes, respectively, the kinetics of response to TG would indicate that the TG-specific T cells have had previous exposure to this autoantigen in vivo. The possibility that the normal human PBMC might be responding to foreign allelic determinants on the administered

autoantigen19 is, therefore, effectively excluded, because such recognition would be of a primary nature. In keeping with their common status as recall Transmembrane Transporters modulator antigens, TT and TG induced vigorous cytokine production from the first day of challenge, whereas KLH only elicited a small amount of TNF-α. However, the cytokine profiles elicited by TT and TG were quite distinct, in that TT induced the rapid secretion of the Th1 cytokines IL-2 and IFN-γ, whereas TG elicited release of TNF-α, IL-4, IL-10 and only a small OSBPL9 amount of IL-2. While TNF-α is regarded as a pro-inflammatory cytokine, IL-10 (produced by the T-cell subset regulatory type 1 T cells,20 B cells21

and monocytes22) is a potent immunoregulator and may protect against autoimmunity by inducing immature dendritic cells to become tolerogenic.23 Interleukin-4 is a classic Th2-cytokine, implicated in protection against thyroiditis,17,24 diabetes9,16,25 and arthritis15 in mice, and in regulation of Th1-responses in humans.18 The protective effect of IL-4 appears to be exerted in concert with IL-10.15,18 It would therefore appear that the pro-inflammatory response to TG by PBMC from healthy donors is counteracted by an anti-inflammatory response. In the subsequent phase of the responses, IL-10 dominated the cytokine response to TG for most donors (67%), although a low level of TNF-α and traces of IFN-γ and IL-5 (at one or two orders of magnitude lower than those seen with TT stimulation) were also detectable. Furthermore, IL-4 was undetectable at day 5, but showed recovery on day 7.

Urinary incontinence status was ascertained using the

Urinary incontinence status was ascertained using the Selleck CHIR99021 International Consultation on Incontinence Questionnaire-Short Form. Results: Among the 683 eligible male participants, 49 men (7.2%) experienced urine leakage for the past 2.6 years (standard deviation [SD] 1.9). Their prevalence of alcohol drinking (beer, sake, shochu, wine, whisky) was lower than others without the condition, even though the daily mean ethanol intakes were similar between the two groups, 31.8 g (SD 45.4) and 31.3 g (SD 41.9), respectively. Relative to non-drinkers, the adjusted odds of urinary incontinence were 0.43 (95% CI 0.19 to 0.96) for low ethanol intake, and up to 32 g per day and 0.53 (95% CI 0.22 to 1.28) for drinking, at most, one can

(350 mL) of beer daily. However, higher levels of alcohol consumption had no significant benefit in reducing the incontinence risk. Conclusion: The findings suggested an inverse association between urinary incontinence and low alcohol consumption particularly beer in middle-aged and older Japanese

men. “
“Most men with lower urinary tract symptoms have both storage and voiding symptoms. Overactive bladder symptoms occur in 50–75% of men with benign prostatic obstruction. Alpha-blockers are usually the first option in medical therapy. Even though voiding symptoms are alleviated by the use of medicines or transurethral resection of the prostate, storage symptoms continue in 30–65% of patients. Combination therapy with an alpha1-receptor antagonist and an anticholinergic agent selleck in benign prostatic hyperplasia patients with overactive bladder symptoms significantly alleviates symptoms and improves quality of life. In clinical practice, the efficacy and safety of anticholinergic combination therapy may not be comparable with well-controlled studies. Overactive bladder symptoms usually require long-term treatment, and benign prostatic hyperplasia

tends to progress with time. When male LUTS patients are treated with anticholinergic combination therapy, there are still some concerns about the development of acute urinary retention, voiding difficulty, and other anticholinergic side-effects. If the drug is prescribed in a relatively low dosage, however, this approach could be appealing regarding adverse effects. There is a Cytidine deaminase relatively small number of clinical reports about low-dose combination therapy, which is in its early stages. Promising results are being reported, though the level of evidence is low. We await the final results. Lower urinary tract symptoms (LUTS) are found commonly in elderly men, and benign prostatic obstruction (BPO) is a common cause of LUTS.1 The prevalence of overactive bladder (OAB) increases with age, and it is similar to the natural history related to benign prostatic hyperplasia (BPH).2 Most men with LUTS have both storage and voiding symptoms, which suggests that BPO and detrusor overactivity (DO) may coexist. OAB occurs in 50–75% of men with BPO.

DCs were cultured together with DX5+CD4+ or DX5−CD4+ supernatant

DCs were cultured together with DX5+CD4+ or DX5−CD4+ supernatant in the presence of blocking antibodies against IL-4 or IL-10. Our results show that inhibition of IL-10 present in the DX5+CD4+ supernatant restored the

ability of DCs to produce IL-12. In contrast, neutralization of IL-4 did not result in the restoration of IL-12 production by DCs (Fig. 3). Together, these findings indicate that IL-10 but not IL-4 secreted by DX5+CD4+ T cells is responsible for the suppression of IL-12 production. The results presented above indicate that DX5+CD4+T cells can modulate the expression and secretion of various molecules involved in T-cell activation and skewing. To analyze whether DX5+CD4+ T-cell-modulated DCs display altered abilities to activate naïve T cells, we next investigated the impact of DC modulation by DX5+CD4+ T cells on the outcome of T-cell responses. To this find more end, we incubated DCs with supernatants of DX5+CD4+ or DX5−CD4+ T-cell selleck products cultures. After extensive washing, the DCs exposed to supernatant from DX5+ (DX5+DCs) or DX5− (DX5−DCs) T-cell cultures

were co-cultured with OVA-specific CD4+ D0.11.10 T cells and OVA peptide. After 3 days, IFN-γ production by OVA-specific CD4+ T cells was analyzed by flow cytometry. Interestingly, OVA-specific CD4+ T cells primed with DX5+DCs produced less IFN-γ as compared with CD4+ T cells primed with either DX5−DCs or DCs exposed to medium only (medium DCs) (Fig. 4A and B and Supporting Information Fig. 3). These data indicate that DCs exposed to the action of DX5+CD4+ T cells are affected in their ability to prime CD4+ T cells for IFN-γ production. As DX5+CD4+ T cells produced factors that inhibited IL-12 production by DCs and as IL-12 is a prominent cytokine capable of inducing IFN-γ production, we next determined whether the reduced IL-12 production was responsible for the effects observed. To this end, we supplemented cultures of naïve OVA-specific T cells and OVA-peptide-loaded DX5+ DC with exogeneous IL-12. Addition

of IL-12 was sufficient to restore the potential oxyclozanide of DX5+DC-primed CD4+ T cells to secrete IFN-γ (Fig. 4C and D and Supporting Information Fig. 3). As inhibition of IL-12 production was dependent on IL-10 present in the DX5+CD4+ T-cell supernatants, we next blocked IL-10 in the supernatant of DX5+CD4+ T-cell cultures upon addition to DCs. These DCs were subsequently used to prime OVA-specific D0.11.10 cells as described above. DCs exposed to anti-IL-10-treated DX5+ supernatant regained their capacity to prime CD4+ T cells for IFN-γ production, as OVA-specific CD4+ T cells were able to produce IFN-γ at levels comparable with (or higher than) that produced by T cells primed by DX5−DCs or medium DCs. Conversely, IFN-γ-production by responding CD4+ T cells was not restored after treatment of DX5+DCs with anti-IL-4 (Fig. 5A and B and Supporting Information Fig. 3).

Irrespective of the exact mechanism, the targeting of TIR adaptor

Irrespective of the exact mechanism, the targeting of TIR adaptor proteins may represent H 89 in vivo a further mechanism underlying the inhibitory effects of

viral Pellino on TLR signalling. Viruses have evolved a wide range of immunoevasive strategies, including the targeting of key innate immune signalling pathways. Vaccinia virus A52R has been shown to inhibit TLR-mediated activation of NF-κB by disrupting signalling complexes containing TRAF6 and IRAK2 28. Furthermore, in a manner similar to the actions of viral Pellino on IRAK-1, MCMV M45 was found to bind RIP1, blocking its ubiquitination and thereby activation of NF-κB by TNF-α and TLR3 signalling 29. Here, we reveal the immunoevasive

properties of a poxviral Pellino homolog. This identifies the ability of an entomopoxvirus protein AZD2014 cell line to combat insect immunity. The ability of viral Pellino to also interfere with TLR signalling highlights the amazing conservation across the evolutionary divide of Toll and TLR signalling. An increased understanding of the mechanistic basis to the regulatory effects of viral Pellino may also provide a greater appreciation of the precise role of mammalian Pellinos in IL-1/TLR signalling. Viral Pellino was initially discovered based on the sequence identity with members of the mammalian Pellino family. However, the sequence identity was quite low and given that the X-ray structure of part of the Pellino2 protein had been recently resolved, we employed homology modelling to evaluate if the limited sequence identity has the potential to translate into shared structural properties. An intriguing picture emerges in which viral Pellino shares some of the structural characteristics of mammalian proteins but differs in other respects. Like some of CYTH4 its mammalian counterparts, it has a cytoplasmic localisation. This is hardly surprising since bioinformatic analysis failed to predict any

transmembrane domain or nuclear localisation sequences. Mammalian Pellinos possess two distinct domains; a N-terminal FHA domain that facilitates binding to phosphorylated IRAK-1 18 and a C-terminal RING-like domain that catalyses polyubiquitination of IRAK-1. Viral Pellino lacks the latter but appears to have the potential to form a FHA domain based on two sets of findings. First, homology modelling in conjunction with molecular dynamics indicates the potential for viral Pellino to form a stable 11-stranded β-sandwich that is characteristic of a canonical FHA domain. Second, viral Pellino shows conservation of the four signature amino acid residues in FHA domain-containing proteins that mediate direct binding to phosphorylated threonine residues on partner proteins.

17–19 However, several studies suggest that nTreg do not universally suppress all T helper cell subsets to the same extent. In newborns, human thymus-derived nTreg strongly suppress Th1 cells but not Th2 cells, and similar properties have been ascribed to nTreg in mice.20,21 Additionally, nTreg isolated from peripheral human blood have been shown to strongly suppress the production and secretion of interferon-γ (IFN-γ), IL-2

and IL-4, but not that of IL-10, in an allogenic model.22 Thus, diurnal changes in the Th1/Th2 balance could also be see more regulated by the diurnal rhythm of nTreg-suppressive activity. We previously demonstrated that the suppression of CD4+ CD25− T-cell proliferation by nTreg followed a sleep-dependent rhythm.23 However, whether

this suppressive rhythm of nTreg affects the proliferation and cytokine secretion of Th1, Th2 and Th17 cells to the same extent is not yet clear. Furthermore, the signal-transduction mechanisms by which nTreg mediate their suppressive function in responder T cells (Tres) are largely unknown in humans. One possible mechanism of diurnal changes in the Th1/Th2/Th17 balance could be the hormonal priming of T cells and/or nTreg in vivo through BGB324 chemical structure the diurnal secretion of hormones with known immunomodulatory effects, such as prolactin, growth hormone, cortisol, noradrenalin and melatonin.8,24–31 To address the vital question of whether nTreg or hormones regulate diurnal changes in the Th1/Th2/Th17 balance, and whether Th1, Selleckchem Gemcitabine Th2 and Th17 cell activity follows a diurnal rhythm, we investigated the activity of the Th1/Th2/Th17 cells and their regulation by nTreg. We were able to demonstrate that nTreg suppressed IFN-γ, IL-2 and tumour necrosis factor-α (TNF-α), but not IL-4, IL-6, IL-10, or IL-17A. The suppression of IL-2 was reduced if nTreg-associated CD25 was inhibited. Highly purified nTreg secreted IL-6, IL-10 and IL-17, but not IL-2, IL-4, IFN-γ or TNF-α. Furthermore, we observed that secretion

of the cytokines IL-2, IFN-γ, TNF-α and IL-10 by naïve CD4+ T cells follows a diurnal rhythm. Multiple regression analysis, as well as subsequent in vitro experiments, suggested that serum levels of cortisol and prolactin contribute to the underlying mechanisms. Taken together, our findings imply that hormones and nTreg contribute to the diurnal secretion of cytokines from T helper cells. Cytokine secretion, and suppression of cytokine secretion by nTreg, was analyzed for Th1 (IFN-γ), Th2 (IL-4, IL-6) and Th17 (IL-17) cytokines, as well as for the cytokines IL-2, IL-10 and TNF-α. Furthermore, the proliferation of cytokine (IL-2, IL-4, IL-10, IL-17A, IFN-γ, TNF-α)-producing CD4+ CD25− Tres was investigated. For these analyses, T cells were isolated from blood samples taken from healthy male donors at 08:30 hr.

29 This dataset was extended to nearly 4000 patients and found 4 year unadjusted survival for those with and without significant RAS to be 57% and 89%, respectively. Survival related to the grade of stenosis, with even mild/moderate lesions (<50%) having significant impact on survival.30 Although these figures are compelling, they do not prove a causal relationship as the presence of stenosis may portent a more diffuse atherosclerotic process. Analysis of over 16 million Medicare claims between 1992 and 2004 confirms increased all cause mortality in patients with ARVD,

with adjusted hazard ratios for death compared with the general population as high as 2.28.31 A complex interplay buy Nutlin-3a between ARVD and the heart is well defined. In all, 95% of patients with ARVD have an abnormality of cardiac structure or function32

and have high mortality from cardiac causes in prospective study.33 A 2005 review of over 1 million Medicare patients showed increases in numbers of all cardiovascular events in those diagnosed with ARVD with annual atherosclerotic heart disease incidence 30.4% compared with 7.4% the general population, Selleckchem p38 MAPK inhibitor CCF (19.5% vs 5.6%), cerebrovascular disease events (17.6% vs 5.3%) and death (16.6% vs 6.3%). These risks were typically highest in the first 6 to 9 months after diagnosis. A review of 146 000 incident US dialysis patients aged over 67 found that patients with ARVD as the primary cause of renal failure, and those with ARVD associated with an alternative renal pathology had higher hazard ratios for cardiovascular events when compared with the remainder of the dialysis

population.34 Proteinuria represents tubulo-interstitial and glomerular injury, and is recognized in many, if not all forms of renal disease as a predictor of progressive dysfunction. Patients with ARVD can have histological patterns discrete from direct ischaemic responses, for example, focal segmental glomerulosclerosis35 and atheroembolic disease. High level, even nephrotic range36 proteinuria can be found in ARVD with increases relating to significantly lower Mannose-binding protein-associated serine protease glomerular filtration rate (GFR),37 but not to arterial patency.38,39 A negative correlation between renal functional outcome and proteinuria has been demonstrated.33 The absence of correlation between level of proteinuria and degree of stenosis suggests down-stream parenchymal damage is the major determinant of outcome. This suggestion is supported by a retrospective review of 83 patients who underwent revascularization, where proteinuria of >0.6 g/day was found to be an independent risk factor for lack of functional improvement or deterioration of function following revascularization.40 Over three decades renal revascularization techniques have evolved from surgical, to angioplasty and more recently, endovascular stenting. The heterogeneity of techniques makes comparison of published data challenging. RCT were limited by small patient numbers and short follow-up periods.

“Mucosal Leishmaniasis (ML) may occur in both nasal and oral mucosa. However, despite the impressive tissue destruction, little is known about the oral involvement. To compare some changes underlying inflammation in oral and nasal ML, we performed immunohistochemistry on mucosal tissue of 20 patients with ML (nasal [n = 12]; oral [n = 8] lesions) and 20 healthy donors using antibodies that recognize inflammatory markers (CD3, CD4, CD8, CD22, CD68, neutrophil elastase, CD1a, CLA, Ki67, Bcl-2, NOS2, CD62E, Fas and FasL). A significantly larger number of cells, mainly T cells and macrophages, were observed in lesions than in healthy tissue. In addition, high nitric oxide synthase 2 (NOS2) expression

was associated with a reduced detection of parasites, highlighting the https://www.selleckchem.com/products/Gefitinib.html importance of NOS2 for parasite elimination. Oral lesions had higher numbers of neutrophils, parasites, proliferating cells and NOS2 than nasal lesions. These findings, together with the shorter duration of oral lesions and more intense symptoms, suggest a more recent inflammatory process. It could be explained by lesion-induced oral cavity changes that lead to eating difficulties and social stigma. In addition, the frequent poor Buparlisib tooth conservation and gingival inflammation tend to amplify tissue destruction and symptoms and may impair and confuse the correct diagnosis,

thus delaying the onset of specific treatment. American tegumentary leishmaniasis (ATL) is a parasitic disease caused by Leishmania protozoa, which are transmitted by insects of the genus Lutzomyia (1). The most common clinical presentation is the presence of cutaneous lesions (2). However, about 3–5% of patients infected with Leishmania (Viannia) braziliensis progress to mucosal leishmaniasis, which mainly affects nasal, oral and laryngeal mucosae (2–4). They are characterized by difficulties in parasite identification and large tissue 5-FU datasheet destruction (5–7). However, the exact mechanisms underlying the formation of mucosal lesions remain unknown (1). The affected mucosa is pale and hyperemic and appears rough, crusty and ulcerative. Nasal septal perforation might be observed in severe cases. Oral lesions frequently involve the lip and palate, although lesions in the uvula, gingiva, tonsils and tongue are reported. The oral mucosa generally appears swollen, ulcerated with a granular bottom and/or presents ulcerovegetative lesions (2–4). To our knowledge, few studies have investigated the in situ immune response in mucosal leishmaniasis (4,6,8–13), and there are no studies comparing the inflammatory activity between nasal and oral infected or healthy mucosae. Here, we characterize the inflammatory infiltrate of oral and nasal lesions or healthy tissues by immunohistochemistry. Forty oral (O) and nasal (N) mucosa samples obtained by biopsy were examined.

During the last decade, monoclonal antibodies targeting these have been tested in clinical trials. Specific therapy targeted against tumour necrosis factor (TNF)-α alone using anti-TNF-α mAbs or soluble TNF-α receptors has been effective in murine collagen-induced arthritis (CIA) by reducing the incidence and severity of disease [16]. Recent studies have shown that therapy with rituximab is one of find more the treatment options for optimizing RA therapy [17]. Furthermore, mAbs directed against this CaMBP gives a promising result in the AIA model, which is

a reliable model for RA because it mimics exactly RA of the human joint [18]. In the present study, our data indicate that 67 kDa protein isolated from SF of RA patients is rheumatoid factor (RF), which is calcium-binding in nature and mediates the inflammatory and destructive process in RA. Monoclonal antibody for novel angiogenic protein (NAP) was produced and the same was used to explore the synergistic role of VEGF and NAP to evaluate the relationship of these proteins in RA. We also studied the correlation of important angiogenic markers CD31, an endothelial cell proliferation indicator, and fms-like tyrosine kinase (Flt1), the receptor for VEGF in AIA and the NAP-induced arthritis (NIA) model. Using enzyme-linked immunosorbent assay (ELISA) and immunohistochemical studies we found that a high level of VEGF is expressed with increased microvessel density

(MVD) in RA. Monoclonal antibodies directed against NAP ameliorate the disease incidence in NIA and an established AIA BI 2536 ic50 rat model. Our studies indicated that anti-NAP mAbs have a potent anti-arthritic effect which targets angiogenesis and can be useful for individualization of therapeutic strategies in treatment of Megestrol Acetate RA. Patients who fulfilled the American College of Rheumatology

criteria for RA [19] were recruited from the out-patient Department of Pathology, JSS Hospital, Mysore, with the approval of the medical college ethics committee and as per the guidelines of the Institutional Review Board. Informed consent was obtained from all the patients. The patient group comprised seven women and three men, with an age range of 38–67 years. Patients had active disease and disease duration of ≤ 2 years. All knee joints demonstrated signs of active synovitis at the time of aspiration. Wistar rats (aged 4–5 months) were obtained from the central animal facility of the Department of Zoology, University of Mysore, Mysore, India. All the animal experiments were approved by the Institutional Animal Ethics Committee, University of Mysore, Mysore and studies were conducted according to the guidelines of the Committee for Purpose of Control and Supervision of Experiments on Animals (CPCSEA), Government of India, India. Novel angiogenic protein was isolated and purified from human SF of patients with RA, as per the method described previously by us [20].

However,

unlike NFAT and AP-1 factors that interact and collaborate in binding to DNA, NFAT, and NF-κB seem neither to interact nor to collaborate. We show here that NF-κB1/p50 and c-Rel, the most prominent NF-κB proteins in BCR-induced splenic B cells, control the induction of NFATc1/αA, a prominent short NFATc1 isoform. In part, this is mediated through two composite κB/NFAT-binding sites in the inducible Nfatc1 P1 promoter that directs the induction of NFATc1/αA by BCR signals. In concert with coreceptor signals that induce NF-κB factors, BCR signaling induces a persistent generation of NFATc1/αA. These data suggest a tight connection between NFATc1 and NF-κB induction in B lymphocytes contributing to the effector function of peripheral B cells. “
“Ficolins are soluble molecules of the innate immune system that recognize carbohydrate molecules on microbial pathogens, apoptotic and necrotic

learn more cells. They act through two distinct routes: initiating the lectin pathway of complement activation and mediating a primitive opsonophagocytosis. In this study, we measured plasma levels of ficolin-2 and ficolin-3 in 60 pre-eclamptic patients, 60 healthy this website pregnant women and 59 healthy non-pregnant women by enzyme-linked immunosorbent assay (ELISA). Circulating levels of complement activation products (C4d, C3a, SC5b9), angiogenic factors (soluble fms-like tyrosine kinase-1, placental growth factor) and markers of endothelial activation (von Willebrand factor antigen), endothelial injury (fibronectin) and trophoblast debris (cell-free fetal DNA) were also determined. Plasma levels click here of ficolin-2 were significantly lower in healthy pregnant than in healthy non-pregnant women, while ficolin-3 levels did not differ significantly between the two groups. Furthermore, pre-eclamptic patients had significantly lower ficolin-2 and ficolin-3 concentrations than healthy non-pregnant and pregnant women. In the pre-eclamptic group,

plasma ficolin-2 levels showed a significant positive correlation with serum placental growth factor (PlGF) concentrations and significant inverse correlations with serum levels of soluble fms-like tyrosine kinase-1 (sFlt-1), blood urea nitrogen and creatinine, serum lactate dehydrogenase activities, as well as with plasma VWF:antigen, fibronectin and cell-free fetal DNA concentrations. In conclusion, circulating levels of ficolin-2 are decreased in the third trimester of normal pregnancy. There is a further decrease in plasma ficolin-2 concentrations in pre-eclampsia, which might contribute to the development of the maternal syndrome of the disease through impaired removal of the trophoblast-derived material released into the maternal circulation by the hypoxic and oxidatively stressed pre-eclamptic placenta.
