Abstract
Objective.This study aimed to test fecal calprotectin (FC) as a screening tool to identify inflammatory bowel disease (IBD) among patients with juvenile idiopathic arthritis (JIA).Methods.FC level < 100 g/kg was considered normal. Patients with 2 consecutive FC dosage ≥ 100 g/kg underwent endoscopic evaluation.Results.There were 113 patients with JIA enrolled. FC was raised in 7 patients out of 113. All patients had IBD. In 3/7 patients, high FC levels were the only sign consistent with IBD.Conclusion.FC is a useful, economical, and noninvasive diagnostic tool to identify JIA patients with underlying IBD.

Abstract
PROBLEM Procalcitonin (PCT) is the prohormone of calcitonin which is usually released from neuroendocrine cells of the thyroid gland (parafollicular) and the lungs (K cells). PCT is synthesized by almost all cell types and tissues, including monocytes and parenchymal tissue, upon LPS stimulation. To date, there is no evidence for PCT expression in the placenta both in physiological and pathological conditions. METHOD Circulating and placental PCT levels were analysed in pre-eclamptic (PE) and control patients. Placental cells and macrophages (PBDM), stimulated with PE sera, were analysed for PCT expression. The effect of anti-TNF-α antibody was analysed. RESULTS Higher PCT levels were detected in PE sera and in PE placentae compared to healthy women. PE trophoblasts showed increased PCT expression compared to those isolated from healthy placentae. PE sera induced an upregulation of PCT production in macrophages and placental cells. The treatment of PBDM with PE sera in the presence of anti-TNF-α completely abrogated the effect induced by pathologic sera. CONCLUSION Trophoblast cells are the main producer of PCT in PE placentae. TNF-α, in association with other circulating factors present in PE sera, upregulates PCT production in macrophages and normal placental cells, thus contributing to the observed increased in circulating PCT in PE sera.

Abstract
Endometrial cancer arises from the endometrium. It has a slow progression and a reported survival rate of 75%. The identification of soluble biomarkers in the uterine aspirate may be very useful for its early diagnosis. Uterine aspirates from 10 patients with endometrial cancer and 6 non-endometrial cancer controls were analyzed by two-dimensional gel electrophoresis coupled with mass spectrometry and western blotting for data verification. A total of 25 proteins with fold change in %V ≥2 or ≤0.5 in intensity were observed to change significantly (P<0.05). From the discovery phase, four proteins (costars family protein ABRACL, phosphoglycerate mutase 2, fibrinogen beta chain, annexin A3) were found to be present in the uterine aspirate of endometrial cancers and not in healthy aspirates. Western blotting verification data demonstrated that costars family protein ABRACL, phosphoglycerate mutase 2 were present only in endometrial cancer uterine aspirate while fibrinogen beta chain, annexin A3 were also present in healthy aspirates. To our knowledge, phosphoglycerate mutase 2 has not been previously associated with endometrial cancer. In this study we demonstrate that uterine aspirates are a promising biological fluid in which to identify endometrial cancer biomarkers. In our opinion proteins like costars family protein ABRACL and phosphoglycerate mutase 2 have a great potential to reach the clinical phase after a validation phase.

Abstract
Nanotoxicology and nanomedicine investigations often require the probing of nano-objects such as fibres and particles in biological samples and cells, whilst internalization and intracellular destiny are the main issues for in vitro cellular studies. Various high resolution microscopy techniques are well suited for providing this highly sought-after information. However, sample preparation, nanomaterial composition and sectioning challenges make it often difficult to establish whether the fibres or particles have been internalized or they are simply overlaying or underlying the biological matter. In this paper we suggest a novel suitable combination of two different microscopic techniques to reveal in intact cells the uptake of asbestos fibres by mesothelial cells. After exposure to asbestos fibres and fixation, cells were first analysed under the AFM instrument and then imaged under the TwinMic soft X-ray microscope at Elettra Sincrotrone. The suggested approach combines standard soft X-ray microscopy imaging and AFM microscopy, with a common non-invasive sample preparation protocol which drastically reduces the experimental uncertainty and provides a quick and definitive answer to the nanoparticle cellular and tissue uptake.

Abstract
PROBLEM We have previously found that C1q is constitutively expressed by invading trophoblast and endothelial cells of decidua and contributes to vascular and tissue remodeling. Based on these findings, we sought to determine whether there were changes in the circulating level of C1q that may be used as a diagnostic and predictive marker of preeclampsia. METHOD OF STUDY We measured the levels of C1q, C4, and complement activation products in serum or plasma of normal pregnant women and preeclamptic patients from different cohorts. RESULTS We observed a marked decrease in the concentration of C1q associated with a reduced level of C4 in preeclamptic patients as compared to matched healthy pregnant woman but no significant difference in the circulating level of the activating products C5a and the soluble terminal complement complex sC5b-9. Analysis of serum samples collected at early phase of pregnancy from women who later developed preeclampsia failed to show a decrease in C1q level. CONCLUSION The results of the present investigation demonstrate that low levels of C1q and C4 are associated with preeclampsia but cannot be used as predictive markers.

Abstract
BACKGROUND Fecal calprotectin is a noninvasive marker for bowel diseases and it is high valuable to follow disease activity in Crohn's disease (CD) and ulcerative colitis (UC). In this study, we evaluated the diagnostic performance of the recently introduced immunochromatographic assay CalFast in comparison to the well-known ELISA tests for calprotectin assay to obtain a rapid diagnosis of bowel inflammation in pediatric patients. METHODS CalFast was tested in parallel to the classic ELISA tests CalPrest and PhiCal (gold standards for the calprotectin determination) on 148 fecal samples from pediatric subjects including 104 healthy subjects, 29 with CD, and 15 with UC. RESULTS In this study, the sensitivity and specificity of CalFast, CalPrest, and PhiCal were 86.4%, 88.6%, and 93.2% and 86.6%, 74%, and 64.4%, respectively. The area under the curve, obtained from receiver operating characteristic analysis, indicated the lack of significant difference among all the kits used. CONCLUSION The immunochromatographic assay demonstrated good diagnostic predictive values, comparable to those of the ELISA methods, and may represent a valid alternative in order to save operators' time. The test, in fact, has a short turnaround time and does not need a specific ELISA instrumentation.

Abstract
It is known that excessive inflammation at fetal-maternal interface is a key contributor in a compromised pregnancy. Female genital tract is constantly in contact with microorganisms and several strategies must be adopted to avoid pregnancy failure. Decidual endothelial cells (DECs) lining decidual microvascular vessels are the first cells that interact with pro-inflammatory stimuli released into the environment by microorganisms derived from gestational tissues or systemic circulation. Here, we show that DECs are hypo-responsive to LPS stimulation in terms of IL-6, CXCL8 and CCL2 production. Our results demonstrate that DECs express low levels of TLR4 and are characterized by a strong constitutive activation of the non-canonical NF-κB pathway and a low responsiveness of the canonical pathway to LPS. In conclusion, DECs show a unique hypo-responsive phenotype to the pro-inflammatory stimulus LPS in order to control the inflammatory response at feto-maternal interface.

Abstract
The causes of extremely elevated IgA, whether isolated or associated with an increase in other classes of immunoglobulin, are poorly defined in paediatrics. We reviewed the diagnostic significance of very high IgA levels (greater than 3 SD above the mean for age) in a cohort of patients referred to a tertiary care children's hospital. Hyper-IgA was found in 91 of 6364 subjects (1.4%) and in 68 cases was not associated with an increased IgG and/or IgM level. Most subjects with hyper-IgA (73.5%) had a severe immune defect, a chronic rheumatic disease or inflammatory bowel disease, while these conditions were very rare in a control group with normal IgA values (8%). Although our results may in part reflect the experience of a tertiary care centre, we suggest that hyper-IgA in children should always arouse suspicion of a serious disease.

Abstract
BACKGROUND Inflammation is believed to link obesity to insulin resistance, as in the setting of metabolic syndrome (MetS). Osteoprotegerin (OPG) is a soluble protein that seems to exert proatherogenic and prodiabetogenic effects. This study aims at determining OPG levels in MetS and whether OPG might contribute to MetS development and progression. METHODOLOGY/PRINCIPAL FINDINGS Circulating OPG was measured in 46 patients with MetS and 63 controls, and was found significantly elevated in those with MetS. In addition, circulating and tissue OPG was significantly increased in high-fat diet (HFD) fed C57BL6 mice, which is one of the animal models for the study of MetS. To evaluate the consequences of OPG elevation, we delivered this protein to C57BL6 mice, finding that it promoted systemic and adipose tissue proinflammatory changes in association with metabolic abnormalities. CONCLUSIONS/SIGNIFICANCE These data suggest that OPG may trigger adipose tissue proinflammatory changes in MetS/HFD-induced obesity.

Abstract
CONTEXT The regulation of the circulating levels of TNF-related apoptosis-inducing ligand (TRAIL), a cytokine of the TNF family, playing a key role in the immune surveillance against cancer, is incompletely understood. OBJECTIVE The objective of the study was to investigate the potential link between TRAIL and 17β-estradiol. DESIGN, SETTING, AND PARTICIPANTS Circulating TRAIL levels were measured by an ELISA in plasma samples (n = 246) of healthy, age-matched (range 30-70 y) men and women and in the sera (n = 180) of females belonging to different physiopathological conditions (childhood, pregnancy, under gonadotropin treatment, menopause) characterized by different levels of circulating 17β-estradiol. RESULTS TRAIL plasma levels in women with aged younger than 50 years were significantly lower compared with age-matched men, whereas in woman 50 years old or older, TRAIL levels were significantly higher compared with the age-matched men and with the younger women. Moreover, an analysis of women with different conditions revealed a significant inverse correlation between the serum levels of TRAIL and 17β-estradiol, with the lowest levels of TRAIL being observed during pregnancy and the highest in childhood and in postmenopausal women. Moreover, gonadotropin treatment in women undergoing assisted reproduction was accompanied by an acute decrease of serum TRAIL levels. Finally, in vitro treatment with 17β-estradiol decreased the TRAIL expression levels in peripheral blood mononuclear cells. CONCLUSIONS Our data suggest that 17β-estradiol plays a role in regulating TRAIL circulating levels. The demonstration that postmenopausal women exhibit the highest TRAIL levels is of particular interest in light of a previous large study population showing that TRAIL is positively correlated to the overall survival.

Abstract
BACKGROUND Human colostrum and breast milk are known to contain high levels of cytokines, cytokine receptors, and chemokines. OBJECTIVE To investigate the presence and compare levels of soluble cytokines in paired samples of human colostrum and milk. METHODS Levels of 27 cytokines were measured in 9 paired samples of human colostrum (day 2 after delivery) and breast milk (day 4 or 5 after delivery) by using multiplex technology. RESULTS The majority of cytokines and chemokines investigated have been previously described in colostrum and/or breast milk. For the first time, we describe the presence of IL-9 in both human colostrum and milk. Of the 27 cytokines investigated, only IL-5 was absent in both colostrum and milk, whereas IL-1β, IL-2, IL-4, IL-15, IL-17, and MIP-1α were present in colostrum, but not in breast milk. In general, colostrum contained higher concentrations of cytokines with respect to human milk. CONCLUSION Our data confirm and expand previous studies showing that human colostrum and breast milk are rich in cytokines and chemokines, including IL-9, which might contribute to the development of the immune system of the newborn.

Abstract
Human colostrum and breast milk are known to contain high levels of cytokines and chemokines, which are thought to contribute to the development of the newborn. The aim of this study was to investigate the difference in the presence and levels of 21 soluble cytokines and chemokines in paired samples of human colostrum (day 2 after delivery) and breast milk (day 4-5 after delivery) by using the multiplex technology. Of the 21 cytokine investigated in 10 pairs of samples, only β-NGF was absent in both colostrum and milk, while INF-α2, SCF and TNF-β were present in colostrum but not in human milk. As a general rule, colostrum contained higher concentrations of cytokines and chemokines with respect to breast milk. The majority of cytokines, detected in colostrum alone or in colostrum and human milk (IL-1α, IL-2Rα, IL-3, IL-16, IL-18, GRO-α, HGF, IFN-α2, M-CSF, MIF, MIG, TNF-β, SDF-1α, TRAIL) have been described in previous studies, while for the first time we describe the presence of additional cytokines either in colostrum alone (SCF) or in both colostrum and breast milk (CTAK/CCL27, MCP-3/CCL7, LIF). Our data confirm and expand previous studies showing that some cytokines/chemokines, which might contribute to the development of the gastro-intestinal and nervous systems, are overexpressed in human colostrum and breast milk, and might contribute to the development of these systems.

Abstract
BACKGROUND Food challenge is required to assess tolerance in cow milk (CM) allergy. A positive challenge contraindicates the reintroduction of CM. Specific oral tolerance induction (SOTI) is a promising treatment. METHODS All children admitted for a challenge were prospectively enrolled. To those tolerating between 2 and 150 ml a SOTI protocol was offered. Outcome, adverse reactions, parents' satisfaction were recorded. RESULTS Out of 245 challenged patients, 175 reacted 122 out of 125, able to tolerate a minimum dose of 2 ml, underwent SOTI. After one year 75.4% were in an unrestricted diet, 16.1% tolerated between 5 and 150 ml, 8.5% stopped SOTI. Side effects were mild, parents' satisfaction was very high. CONCLUSIONS The majority of children tolerating limited amounts of CM at the challenge acquires tolerance with SOTI without relevant side effects. Maintaining on an exclusion diet partially tolerant children should be considered debatable.

Abstract
BACKGROUND Specific oral tolerance induction (SOTI) is a promising approach for severe food allergies. There are little data in the literature regarding the home-phase of SOTI, not only with regard to type and frequency of adverse reactions but also regarding the most suitable treatment and protocol. AIMS To define the incidence and severity of adverse reactions, possible risk factors, and the safety and effectiveness of the home-phase of an original SOTI protocol in a large group of children with severe cow's milk (CM) allergy, after the hospital "rush" phase. METHODS The study was conducted by recording in-home phase adverse events, success and failure as reported by parents, and calling families. Adverse reactions were treated following the International Guidelines, arbitrarily modified by introducing nebulised epinephrine for respiratory reactions, oral beclomethasone for acute gastric pain and oral cromolyn for recurrent gastric pain. RESULTS Out of 140 patients, 132 were contacted; eight were inaccessible (follow-up 2-84 months). The number of adverse reactions was 1 in every 100 doses. The reactions were treated with nebulised epinephrine (221 reactions), IM epinephrine (6 reactions), and other drugs. Patients with high specific IgE levels (greater than 100 kU(A)/L) and lower CM dose (less than 5 ml) at the end of in-hospital phase showed a higher risk both for number of reactions and use of nebulised epinephrine. CONCLUSIONS The home phase of SOTI was characterised by a significant number of adverse reactions, mostly managed with an acceptable rate of side effects. Nebulised epinephrine played a pivotal role in respiratory reactions.

Abstract
Background Since circulating levels of TNF-related apoptosis inducing ligand (TRAIL) may be important in the physiopathology of pregnancy, we tested the hypothesis that TRAIL levels change at delivery in response to stressful conditions. Methods/Principal Findings We conducted a longitudinal study in a cohort of 73 women examined at week 12, week 16, delivery and in the corresponding cord blood (CB). Serum TRAIL was assessed in relationship with maternal characteristics and to biochemical parameters. TRAIL did not vary between 12 (67.6±27.6 pg/ml, means±SD) and 16 (64.0±16.2 pg/ml) weeks' gestation, while displaying a significant decline after partum (49.3±26.4 pg/ml). Using a cut-off decline >20 pg/ml between week 12 and delivery, the subset of women with the higher decline of circulating TRAIL (41.7%) showed the following characteristics: i) nullipara, ii) higher age, iii) operational vaginal delivery or urgent CS, iv) did not receive analgesia during labor, v) induced labor. CB TRAIL was significantly higher (131.6±52 pg/ml) with respect to the corresponding maternal TRAIL, and the variables significantly associated with the first quartile of CB TRAIL (<90 pg/ml) were higher pre-pregnancy BMI, induction of labor and fetal distress. With respect to the biochemical parameters, maternal TRAIL at delivery showed an inverse correlation with C-reactive protein (CRP), total cortisol, glycemia and insulin at bivariate analysis, but only with CRP at multivariate analysis. Conclusions Stressful partum conditions and elevated CRP levels are associated with a decrease of circulating TRAIL.

Abstract
BACKGROUND Chronic urticaria (CU) is one of the most common skin disorders whose pathogenic mechanisms are not fully clarified. Autoimmune aetiology can be ascribed to 45% of patients with CU, and basophil histamine release is positive in 40% of cases. Our aim was to use a novel approach to evaluate the serum permeabilizing effect to identify the mediators of endothelial cell (EC) leakage and to define the role of mast cells (MCs) in the process. METHODS Permeabilizing activity of sera from 19 patients with CU and 11 healthy blood donors was evaluated by measuring serum-induced degranulation of two MC lines, expressing (LAD2) or lacking (HMC-1) the IgE receptor. Mast cell supernatant (SN) was then incubated with an EC monolayer, and endothelial permeability was evaluated by Fluorescein isothiocyanate-bovine serum albumin leakage in a transwell system. RESULTS All 19 patient sera failed to induce direct EC leakage, but 15/19 and 17/19 promoted degranulation of HMC-1 and LAD2, respectively. Interestingly, 85% of autologous serum skin test-negative sera were able to cause MC degranulation. Also, 17/19 SNs from HMC-1 and all SNs from LAD2 incubated with CU sera increased endothelial permeability. Endothelial cell leakage remained unchanged after Ig depletion and was prevented by antihistamine, platelet-activating factor or leukotriene antagonist. CONCLUSIONS Our study shows that CU sera are able to degranulate MCs through an IgE- and IgG-independent mechanism. The nature of histamine-releasing factors involved is still unclear, but our finding opens new ways to the understanding of the pathogenesis of CU, particularly in patients not showing circulating autoantibodies to FcεRI or IgE.

Abstract
To improve the pharmacokinetic profile of tumor necrosis factor-related apoptosis inducing ligand (TRAIL) an N-terminal specific pegylation was performed to generate pegylated TRAIL (PEG-TRAIL). In in vitro experiments, we found that although PEG-TRAIL was slightly less efficient than recombinant TRAIL in promoting leukemic cell apoptosis, it showed an improved ability to promote migration of bone-marrow mesenchymal stem cells and to elicit the ERK1/2 intracellular signal transduction pathway. Overall, these data suggest that TRAIL pegylation retains, or even enhances, the biological activities of TRAIL relevant for its therapeutic applications.

Abstract
Mannose-binding lectin (MBL) is a recognition molecule of the complement (C) system and binds to carbohydrate ligands present on a wide range of pathogenic bacteria, viruses, fungi, and parasites. MBL has been detected in the cervico-vaginal cavity where it can provide a first-line defence against infectious agents colonizing the lower tract of the reproductive system. Analysis of the cervico-vaginal lavage (CVL) obtained from 11 normal cycling women at different phases of the menstrual cycle revealed increased levels of MBL in the secretive phase. Part of this MBL derives from the circulation as indicated by the presence of transferrin in CVL tested as a marker of vascular and tissue permeability. The local synthesis of MBL is suggested by the finding that its level is substantially higher than that of transferrin in the secretive phase. The contribution of endometrium is negligible since the MBL level did not change before and after hysterectomy. RT-PCR and in situ RT-PCR analysis showed that the vaginal tissue, and in particular the basal layer of the epithelium, is a source of MBL which binds to the basal membrane and to cells of the outer layers of the epithelium. In conclusion, we have shown that MBL detected in CVL derives both from plasma as result of transudation and from local synthesis and its level is progesterone dependent increasing in the secretive phase of the menstrual cycle.

Abstract
OBJECTIVE We evaluated mannose binding lectin (MBL) protein production and histological localization, MBL2 gene expression and genotypes distribution in patients characterized by recurrent tonsillitis, with the aim of verifying the innate immune response to the infection and inflammation occurring in the tonsils. METHODS MBL2 exon 1 and promoter polymorphims were detected by PCR amplification and subsequent direct sequencing of the amplicons. Monoclonal antibodies to MBL were used on frozen sections of tonsils for the immunohistochemical localization of MBL protein. MBL Oligomer ELISA kit was used to quantify the level of MBL in the serum of the 30 patients with recurrent tonsillitis. Quantitative RT PCR for the evaluation of MBL2 expression of MBL high producers (HP), low producers (LP) and deficient producers (DP) was performed using the Hs00175093 gene-expression Assay on Demand. RESULTS The distribution of the MBL2 combined genotypes was as follows: 21 HP (70%; 15 HYA/HYA, 6 HYA/LXA), 6 LP (20%; 5 HYA/0, 1 LXA/LXA) and 3 DP (10%, all 0/0). MBL levels were directly correlated to the MBL2 combined genotypes: HP patients showed higher mean MBL concentration of 4044 ng/mL, LP patients were characterized by a mean of 905 ng/mL whereas those with DP combined genotype presented extremely low levels of MBL (mean value of 74 ng/mL) (p=0.0005). Immunohistochemistry performed on tonsils sections demonstrated that MBL was widely distributed throughout the surface of the basal lamina of all the 21 HP subjects. MBL was undetectable in situ in both LP and DP patients. MBL2 expression, although at very low levels, was found for the HP group, the LP and the DP group as well. CONCLUSIONS We confirmed the genotype-phenotype correlation of MBL2 gene exon 1 and promoter polymorphisms with the quantitative production of serum MBL, we reported a very low MBL2 expression at local level in tonsils and we determined the in situ localization of MBL in the basal lamina of the tonsils of patients who underwent to tonsillectomy. Our findings suggest an important role of MBL protein in the innate immune response of the tonsil to pathogens, as in recurrent infection and inflammation.

Abstract
This study was prompted by the observation that decidual endothelial cells (DECs), unlike endothelial cells (ECs) of blood vessels in normal skin, kidney glomeruli and brain, express surface-bound C1q in physiologic pregnancy. This finding was unexpected, because deposits of C1q are usually observed in pathologic conditions and are associated with complement activation. In the case of DECs, we failed to detect immunoglobulins and C4 co-localized with C1q on the cell surface. Surprisingly, DECs expressed mRNA for the three chains of C1q and secreted detectable level of this component in serum-free medium. The ability to synthesize C1q is acquired by DECs during pregnancy and is not shared by ECs obtained from endometrium and from other sources. Cell-associated C1q has a molecular weight similar to that of secreted C1q and is released from DECs following treatment with heparinase or incubation at low pH. This suggests that C1q binds to DECs and it is not constitutively expressed on the cell surface. C1q is localized at contact sites between endovascular trophoblast and DECs and acts as an intercellular molecular bridge because adhesion of endovascular trophoblast to DECs was inhibited by antibodies to C1q and to a receptor recognizing its globular portion expressed on trophoblast.

Abstract
Cell adhesion and motility are central aspects in the pathophysiology of B cell chronic lymphocytic leukemia (B-CLL), but the role of specific extracellular matrix proteins is still to be completely unveiled. Purified peripheral blood neoplastic cells of B-CLL patients migrated poorly on laminins-111,-411,-511, but showed pronounced motility on laminin (LM)-332 in a high percentage of cases. B-CLL cell motility on LM-332 was mediated by the alpha3beta1 integrin and was preferentially observed in cells carrying a mutated IgV(H) gene profile. Within normal lymph nodes, LM-332 was circumscribed around blood vessels and to areas corresponding to marginal zones, where it was deposited in a pattern reminiscent of reticular fibers. Conversely, in B-CLL involved lymph nodes, a positive LM-332 reticular mesh was diffusely evident, throughout the disrupted nodal architecture. In the present study we identified LM-332 as a crucial motility-promoting factor for B-CLL lymphocytes and as a potential constituent favoring the dissemination of B-CLL lymphocytes through vascular basement membranes and possibly lymph node compartments.

Abstract
The detection of EMILIN1, a connective tissue glycoprotein associated with elastic fibers, at the level of the ectoplacental cone and trophoblast giant cells of developing mouse embryos (Braghetta et al., 2002) favored the idea of a structural as well as a functional role for this protein in the process of placentation. During the establishment of human placenta, a highly migratory subpopulation of extravillous trophoblasts (EVT), originating from anchoring chorionic villi, penetrate and invade the uterine wall. In this study we show that EMILIN1, produced by decidual stromal and smooth muscle uterine cells, is expressed in the stroma and in some instances as a gradient of increasing concentration in the perivascular region of modified vessels. This distribution pattern is consistent with the haptotactic directional migration observed in in vitro functional studies of freshly isolated EVT and of the immortalized HTR-8/SVneo cell line of trophoblasts. Function-blocking monoclonal antibodies against alpha4-integrin chain and against EMILIN1 as well as the use of EMILIN1-specific short interfering RNA confirmed that trophoblasts interact with EMILIN1 and/or its functional gC1q1 domain via alpha4beta1 integrin. Finally, membrane type I-matrix metalloproteinase (MT1-MMP) and MMP-2 were upregulated in co-cultures of trophoblast cells and stromal cells, suggesting a contributing role in the haptotactic process towards EMILIN1.

Abstract
In our study we examined the early complement components in patients with bacterial vaginosis (BV), vulvovaginal candidiasis (VVC) and in healthy controls. The levels of C1q, mannose-binding lectin (MBL) and C3 were measured by ELISA in the cervicovaginal lavage (CVL) from gynaecological patients and controls. No significant differences were observed in the levels of these proteins in the three study groups. Immunofluorescence analysis of the clue cells and Candida hyphae from BV and VVC patients for surface-bound complement components showed the presence of C3, while C1q was undetectable. MBL was revealed on clue cells but not on Candida. Binding of MBL to Candida, grown or cytocentrifuged from the CVL of VVC patients, was found to be pH dependent and occurred between pH 4.5 and pH 5.5. In conclusion, we demonstrated that MBL and C3 present in the vaginal cavity act as recognition molecules for infectious agents that colonize the cervicovaginal mucosa. Our finding that MBL, but not C1q, binds to bacteria and fungi in vagina suggests that the lectin and classical pathways of complement activation may play a different role in immune defence in the female genital tract.

Abstract
Fetal cytotrophoblasts colonize the decidual spiral arteries during pregnancy and partially replace the endothelium by an as yet unknown mechanism. To clarify this issue, we cocultured trophoblast cells (TCs) and decidual endothelial cells (DECs) isolated from first trimester placentae and found by electron microscopic analysis that TCs adhered to DECs and migrated through the interendothelial junctions within 24 h. Since extravillous TCs were shown by FACS analysis to express vascular-endothelial (VE)-cadherin and platelet endothelial cell adhesion molecule-1 (PECAM)-1, we investigated the role of these junctional molecules in TC adhesion to DECs and transendothelial migration of cytotrophoblasts. Both VE-cadherin and PECAM-1 were present at the contact sites between TCs and DECs in decidual sections. TC adhesion and migration were markedly inhibited by mAbs to VE-cadherin and marginally by mAb to PECAM-1. Increased expression of VE-cadherin was observed at the contact areas between TCs and DECs, whereas PECAM-1 was found to be redistributed from intercellular junctions. The induction of apoptosis of DECs by TCs, as the mechanism responsible for their replacement, was ruled out by the negative staining with TUNEL of DECs cocultured with TCs and the absence of DNA fragmentation. In conclusion, VE-cadherin is involved in transendothelial migration of TCs, and replacement of DECs by TCs is not the result of apoptosis.

Abstract
Celiac disease is a multifactorial disorder caused, in genetically susceptible patients, by the ingestion of dietary gluten. Very little is known about the genetic factors, but there is a strong association of two HLA haplotypes (DQ2 or alpha1*05, beta1*02 and DQ8 or alpha1*0301, beta1*0302) with the disease. We investigated the relationship between polymorphisms in the first exon of the MBL2 gene, which encodes for mannose binding lectin (MBL) and celiac disease. Moreover we studied the MBL role by immunohistochemistry and TUNEL. Results were confirmed by clinical findings. We enrolled 149 Italian celiac patients; 116 were characterized by the presence of DQ2 or DQ8. The HLA haplotype was established by allelic specific PCR while the MBL2 genotype was resolved by melting temperature assay. Immunohistochemistry and TUNEL assays were performed on serial sections of biopsy specimens from celiac patients and healthy controls. MBL2 allele and genotype frequencies varied significantly between celiac patients and healthy controls. The frequencies of the 0 allele were 28% in DQ2 or DQ8 celiac patients, 36% in HLA atypical celiac patients, and 22% in healthy controls. Interestingly, the MBL2 0/0 genotype was present in 7 of 33 HLA atypical celiac patients (21%) and in 13 of 116 HLA typical celiac patients (13%) but in only 7 of 147 healthy controls (5%). Furthermore, we found that MBL2 genotype is strongly associated with the occurrence of secondary autoimmune diseases. Immunohistochemistry and TUNEL findings support a role of MBL2 in the clearance of apoptotic cells. In conclusion, MBL2 variants, responsible for lower MBL levels, are associated with celiac disease and higher risk of developing autoimmune diseases. Here we propose a role for MBL in the disease which could be easily applied to other autoimmune disorders.

Abstract
Evaluation of heart rate variability (HRV) is based on analysis of consecutive R-R intervals and may provide quantitative information on the modulation of cardiac vagal and sympathetic efferent activities. In particular, power spectral analysis as well as the fractal dimension of HRV represent non-invasive measures that reflect brain-heart interaction in different physiopathological conditions. This study was performed to investigate the relationship between autonomic nervous cardiac influence and three phases (menses, follicular phase and luteal phase) of the menstrual cycle. Heart rate (HR) was recorded in 6 eumenorrheic young females, continuously for 20 min, at rest. From the tachograms, fractal dimension, FFT spectra and beta coefficient were evaluated. The components of two spectral bands were calculated: 0.040 Hz - 0.150 Hz (low frequency, LF), and 0.150 Hz - 0.80 Hz (high frequency, HF). The results indicate no correlation between HR and follicular as well as luteal phase of the menstrual cycle. Total power and HF spectral component increase, whereas LF spectral component decreases in the luteal phase compared to the follicular one. The fractal dimension does not show significant differences among the three phases. Beta coefficient decreases during luteal phase in respect of follicular one and menses. In conclusion, these results indicate in healthy young women a correlation between female sex hormones (17 beta-oestradiol, progesterone and pituitary gonadotrophins) concentrations and some HRV parameters with higher HR variability during the luteal phase.

Abstract
Pregnancy is a unique physiologic condition that guarantees the survival of the semiallogenic embryo during the long period of gestation. The placenta plays a key role in the maintenance of local tolerance and allows the mother to accept the embryo until completion of pregnancy. The complex process of tolerance accompanying the survival of the foetus is controlled at the embryo-maternal interface by factors deriving from decidualized endometrium and from the trophoblast itself. Trophoblasts develop various strategies to evade the damaging attack by the maternal immune response including expression of non-classical MHC class I antigens and of complement regulatory proteins. Also, cytokines released at the feto-maternal interface play an important role in regulating embryo survival controlling not only the maternal immune response but also angiogenesis and vascular remodelling. The delicate equilibrium established between the mother and the foetus can be compromised in pathological condition of pregnancy as a result of humoral and/or cellular response of the mother against trophoblast antigens leading to spontaneous miscarriage. Cytotoxic cells and antibodies to trophoblast and endothelial cells are frequently found in patients with recurrent spontaneous abortion. This review article focuses on the delicate equilibrium established at the feto-maternal interface during pregnancy examining the various strategies devised by the embryo to evade the maternal immune attack, and the pathological conditions in which this equilibrium is compromised leading to serious complications of pregnancy.

Abstract
OBJECTIVE To investigate the seroimmunologic (CD3, CD4, CD8 lymphocytes, C3c and C4 complement fractions, and several autoantibodies) and immunohistochemical (T lymphocyte subpopulations, B lymphocytes, natural killer cells, macrophages, immunoglobulin [Ig] G, Ig M, and C3c complement fraction) characteristics of vulvar lichen sclerosus. METHODS Serum samples from 68 women with histologically proven lichen sclerosus were compared with those from 53 healthy controls, and tissue samples from 14 of 68 women chosen at random were compared with those from 14 of 53 healthy controls. A scoring system was constructed to compare the number of cells in the tissue. RESULTS Patients had significantly lower counts of circulating lymphocytes CD3 and CD4 than controls (P < .05) and a higher number of autoantibodies (P < .01). Analysis of the tissue samples confirmed a lower number of CD2 cells (two-tailed P = .002 in epidermis, .005 in dermis), CD3 cells (two-tailed P = .001 in epidermis and in dermis), CD4 cells (two-tailed P = .002 in epidermis, .011 in dermis), and CD8 cells (two-tailed P = .002 in epidermis, .051 in dermis) in subjects than in controls. Numbers of monocyte-macrophage cells were similar in the epidermis but different in the dermis (two-tailed P = .003). No natural killer CD56 cells or B lymphocytes (CD19-CD21) were detected in the affected areas. Deposits of IgG, IgM, and C3 were no greater in biopsy specimens of patients than in those of controls. CONCLUSION Vulvar lichen sclerosus is not caused by a T cell-mediated response, and a viral origin is unlikely. The absence of CD19 and CD21 cells excludes local production of autoantibodies. Our data do not confirm an autoimmune pathogenesis for vulvar lichen sclerosus but help explain why systemic cortisone is of no benefit and justify the use of petroleum jelly to relieve pruritus.

Abstract
Forty-one sera of patients with IDDM (insulin-dependent diabetes mellitus) containing complement-fixing islet cell antibodies were analyzed for their ability to activate TCC (terminal complement complex). Eighteen sera were found to promote deposition of TCC on human islets of pancreatic cryostat sections with a nonhomogeneous pattern of distribution corresponding to that of insulin. Activation of TCC by IDDM serum and binding of this complex to islet cells was confirmed using purified islets. Flow cytometric analysis of islet cell treated with a TCC+ IDDM serum showed IgG binding to the cell surface. The same serum had a cytotoxic effect on islet cells in the presence of human C. These results obtained with a homologous system of C activation by IDDM sera suggest that TCC may contribute, at least in part, to the pancreatic beta cell damage.

Abstract
Immunohistochemical analysis of tissue specimens from human pregnancy decidua basalis in contact with invasive trophoblast of chorion frondosum and decidua parietalis in contact with non-invasive chorion laeve do not differ in the frequency of lymphoid cells of the following phenotypes (CD2, CD4, CD8, CD14, CD21 and gamma/delta TCR). A practical implication of this observation is that the collection of lymphoid cells from whole decidua by curettage for functional studies is justified.

Abstract
Platelet aggregation inhibition, induced by prostaglandin E1 (PGE1), was evaluated in 38 patients affected by migraine. Our data indicate a complete insensitivity to PGE1 in these subjects. The insensitivity to PGE1 leads to decreased cyclic-AMP (cAMP) levels, determining an imbalance in the inhibitory mechanism. From this observation we can suppose that the decreased affinity of PGE1-receptors, causing decreased cAMP levels, may be involved in pathogenesis of migraine.
