Gumusoglu SB. The role of the placenta-brain axis in psychoneuroimmune programming. Brain Behav Immun Health 2024; 36:100735. [PMID: 38420039 PMCID: PMC10900837 DOI: 10.1016/j.bbih.2024.100735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/06/2024] [Accepted: 02/04/2024] [Indexed: 03/02/2024] Open
Abstract
Gestational exposures have enduring impacts on brain and neuroimmune development and function. Perturbations of pregnancy leading to placental structure/function deficits, cell stress, immune activation, and endocrine changes (metabolic, growth factors, etc.) all increase neuropsychiatric risk in offspring. The existing literature links obstetric diseases with placental involvement to offspring neuroimmune outcomes and neurodevelopmental risk. Psychoneuroimmune outcomes in offspring brain include changes to microglia, cytokine/chemokine production, cell stress, and long-term immunoreactivity. These outcomes are altered by structural, anti-angiogenic/hypoxic, inflammatory, and metabolic diseases of the placenta. This fetal programming occurs via direct placental passage or production of factors which can act directly on fetal brain substrates, or indirectly via action of circulating factors on intermediates in the placenta. Placental neuroendocrine, vascular/angiogenic, immune, and extracellular vesicular mechanisms are detailed. These mechanisms interact within various placental and pregnancy conditions. An increased understanding of the placental origins of psychoneuroimmunology will yield dividends for human health. Identifying maternal and placental biomarkers for fetal neuroimmune health may also revolutionize early diagnosis and precision psychiatry, empowering patients to make the best healthcare decisions for their families. Targeting placental mechanisms may be a valuable approach for the prevention and mitigation of intergenerational, lifelong neuropathology.

Abstract
Background Preeclampsia (PreE), the de novo onset of hypertension and proteinuria at 20 weeks of gestation, is a leading cause of maternal and fetal morbidity and mortality. This study compared inflammatory biomarkers in PreE and normal pregnancies using paired samples of mothers and neonates. Methods Twenty normal pregnant and 27 PreE patients were monitored for biomarkers, neonatal outcomes, and placental morphologies. Fetal and maternal serum levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble endoglin (sENG), and soluble fms-like tyrosine kinase-1 (sFLT-1) were measured by enzyme-linked immunosorbent assay. Results Placental thickness was 25 mm in early PreE subjects compared to 32 mm in late PreE subjects (P < 0.05). Placental volume was 296 cm3 in early PreE compared to 393 cm3 in late PreE (P < 0.05). The average hospital stay for PreE babies was longer (20 ± 5 days) compared to babies from normal pregnancies (2 ± 1 days; P < 0.05). PreE babies had a lower Ponderal index (2.28 ± 0.3) than those from normal pregnancies (2.95 ± 0.2; P < 0.05). sENG and sFLT-1 had cord values like the maternal values, while VEGF and PlGF did not. Conclusion PreE alters the intrauterine environment by activating chemical mediators that result in maternal and fetal complications.

Ulinastatin ameliorates preeclampsia induced by N(gamma)-nitro-l-arginine methyl ester in a rat model via inhibition of the systemic and placental inflammatory response. J Hypertens 2023; 41:150-158. [PMID: 36453658 DOI: 10.1097/hjh.0000000000003316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/05/2022]
Abstract
BACKGROUND The pathogenesis of preeclampsia (PE) is associated with inflammation and endothelial damage. Ulinastatin (UTI) mainly inhibits proteolytic activity and significantly reduces the release of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) from macrophages. It also ameliorates vascular endothelial damage in pathological conditions. Hence, we investigated the effects of UTI in a rat model of PE induced using N(gamma)-nitro-l-arginine methyl ester (L-NAME). METHODS Although inducing PE in a rat model, 5000 U/kg of UTI were injected daily. Systolic blood pressure (SBP) and protein levels in the urine were measured. Renal function, and serum concentrations of TNF-α, IL-6, placental growth factor (PLGF), and von Willebrand factor (vWF) were evaluated. The number and weight of live fetuses as well as the weight of placentas were measured. Placentas were collected for western blot and pathological analysis. RESULTS UTI slightly ameliorated proteinuria and the increases in SBP, blood urea nitrogen (BUN), and serum creatinine. Furthermore, UTI improved serum and placental protein expression levels of TNF-α, IL-6, vWF, and PLGF. Pathological analysis revealed that vascular density and blood flow perfusion was enhanced, vessel wall thickening and neutrophil infiltration were diminished, and the weight and number of live fetuses as well as the weight of the placentas were improved with UTI. CONCLUSION Preventive use of UTI in the PE rat model induced by L-NAME partially alleviated hypertension, proteinuria, and impaired renal function; improved fetal growth restriction; diminished vascular endothelial injury; and ameliorated placental vasculogenesis abnormality and malperfusion by inhibiting the systemic and placental inflammatory response, suggesting that UTI is a potential drug for PE prevention or treatment.

Abstract
Maternal lipid metabolism status during pregnancy may have pivotal effects on a healthy pregnancy, the progression of labor, and childbirth. Based on evidence, changes in maternal lipid profile and metabolism is related to various alterations in fetal metabolic status, fat mass, birth weight and can result in serious maternal and fetal complications. 15-lipoxygenase accounts as a key enzyme in metabolizing polyunsaturated fatty acids that generate various inflammatory lipid metabolites. The possible involvement of 15- lipoxygenase and its metabolites in the inflammatory process, cell proliferation and death, and immune response has been postulated. The indicative role of the 15- lipoxygenase enzymatic pathway in the implantation process, stages of pregnancy, embryogenesis, organogenesis, progression of labor, pregnancy period, and pregnancy-associated complications is remarkable. Accordingly, this study will review the research conducted on the role of 15- lipoxygenase in different reproductive tissues, and its pathological role in pregnancy-related diseases to provide more insight regarding the emerging role of 15-lipoxygenase in normal pregnancy.

Abstract
The metabolic state of pregnant women and their unborn children changes throughout pregnancy and adapts to the specific needs of each gestational week. These adaptions are accomplished by the actions of enzymes, which regulate the occurrence of their endogenous substrates and products in all three compartments: mother, placenta and the unborn. These enzymes determine bioactive lipid signaling, supply, and storage through the generation or degradation of lipids and fatty acids, respectively. This review focuses on the role of lipid-metabolizing serine hydrolases during normal pregnancy and in pregnancy-associated pathologies, such as preeclampsia, gestational diabetes mellitus, or preterm birth. The biochemical properties of each class of lipid hydrolases are presented, with special emphasis on their role in placental function or dysfunction. While, during a normal pregnancy, an appropriate tonus of bioactive lipids prevails, dysregulation and aberrant signaling occur in diseased states. A better understanding of the dynamics of serine hydrolases across gestation and their involvement in placental lipid homeostasis under physiological and pathophysiological conditions will help to identify new targets for placental function in the future.

Abstract
Antiangiogenic factors are currently used for the prediction of preeclampsia. The present study aimed to evaluate the relationship between antiangiogenic factors and lipid and carbohydrate metabolism in maternal plasma and placenta. We analyzed 56 pregnant women, 30 healthy and 26 with preeclampsia (including early and late onset). We compared antiangiogenic factors soluble Fms-like Tyrosine Kinase-1 (sfLt-1), placental growth factor (PlGF), and soluble endoglin (sEng)), lipid and carbohydrate metabolism in maternal plasma, and lipid metabolism in the placenta from assays of fatty acid oxidation, fatty acid esterification, and triglyceride levels in all groups. Antiangiogenic factors sFlt-1, sFlt-1/PlGF ratio, and sEng showed a positive correlation with triglyceride, free fatty acid, and C-peptide maternal serum levels. However, there was no relationship between angiogenic factors and placental lipid metabolism parameters. Free fatty acids were predictive of elevated sFlt-1 and sEng, while C-peptide was predictive of an elevated sFlt1/PlGF ratio. The findings in this study generate a model to predict elevated antiangiogenic factor values and the relationship between them with different products of lipid and carbohydrate metabolism in maternal serum and placenta in preeclampsia.

Abstract
Endothelial cell dysfunction is an essential pathophysiological feature of preeclampsia (PE). It has been reported that cathepsin C is upregulated in the maternal vascular endothelium of PE patients. The excessive activation of p38 MAPK leads to various diseases, including PE. NF-κB pathway can promote uteroplacental dysfunction, endothelial stress and development of PE. Moreover, it has been verified that cathepsin C can activate p38 MAPK/NF-κB pathway. In the present work, hypoxia/reoxygenation (H/R) injury model of HUVECs was established to discuss the biological functions of cathepsin C in endothelial cell dysfunction and to elucidate the underlying molecular mechanism. The correlation between cathepsin C and p38 MAPK/NF-κB pathway in H/R-stimulated HUVECs as well as the effects of cathepsin C and p38 MAPK/NF-κB pathway on viability, apoptosis, invasion, in vitro angiogenesis of HUVECs and oxidative stress were assessed. The results revealed that H/R injury elevated cathepsin C expression and activated p38 MAPK/NF-κB pathway in HUVECs and cathepsin C knockdown inhibited the activity of p38 MAPK/NF-κB pathway in H/R-stimulated HUVECs. Downregulation of cathepsin C improved viability, inhibited apoptosis and enhanced invasion of H/R-stimulated HUVECs. In addition, downregulation of cathepsin C alleviated oxidative stress and induced stronger HUVEC angiogenesis in vitro. Furthermore, the protective effects of cathepsin C knockdown against endothelial cell dysfunction were reversed by p38 MAPK activator anisomycin. In other words, downregulation of cathepsin C could improve HUVEC viability and enhance anti-apoptotic capacity, anti-oxidative capability, invasive ability, as well as angiogenic potential of H/R-stimulated HUVECs by repressing p38 MAPK/NF-κB pathway.

Abstract
OBJECTIVE This systematic review and meta-analysis study was performed to assess the potential association between interleukin-1 beta (IL-1β) single nucleotide polymorphisms (SNPs) (rs1143634 and rs16944) and interleukin-6 (IL-6) SNP (rs1800795) and pre-eclampsia (PE). METHODS A comprehensive literature search was conducted in the international search engines and databases, including MEDLINE (via PubMed), Scopus, and Web of Science (ISI) up to 9 March 2021. After retrieving relevant articles, data extraction was performed by four authors independently. Pooled ORs and corresponding 95% CIs were used to evaluate the association between IL-1β and IL-6 polymorphisms and PE risk. Cochran's Q test was used to check heterogeneity, and the I2 index was calculated for measuring the heterogeneity between the estimations of included studies. RESULTS After reviewing fully published studies, 21 studies were included in this study based on the eligibility criteria. Our results showed that rs16944 and rs1143634 of IL-1β were significantly associated with the risk of PE. Regarding rs16944, the minor C allele significantly decreased the risk of PE (C vs. T: OR = 0.79, 95% CI = 0.69-0.90). In contrast, the minor T allele of rs1143634 significantly increased the risk of PE (T vs. C: OR = 1. 28, 95% CI = 1.04-1.58). There was no significant association between IL-6 rs1800795 (C vs. G: OR = 1.04, 95% CI = 0.93-1.16) polymorphism and PE risk. CONCLUSIONS In conclusion, this meta-analysis suggests rs1143634 and rs16944 polymorphisms of IL-1β are related to the risk of PE.

Abstract
INTRODUCTION Women who smoke during pregnancy have a reduced risk of preeclampsia. The mechanism of this association is poorly understood. Preeclampsia is an anti-angiogenic and inflammatory state. Transforming growth factor beta 1 (TGF-β1) is a multi-functional anti-inflammatory cytokine that activates membrane bound endoglin on endothelial cells causing a myriad of vascular actions including vasorelaxation. The objective of the study was to determine serum levels of cytokines, angiogenic factors, placental growth factor (PlGF), TGF-β-1 and anti-angiogenic factors, soluble endoglin (sEng) and soluble vascular endothelial growth factor 1 (sVEGFR1) in smoking and non-smoking pregnant women. METHODS Using enzyme-linked immunosorbent and multiplex assays we prospectively analyzed serum levels of PIGF, TGF-β1, sEng, sVEGFR1 and cytokines in normotensive pregnant smokers and non-smokers. Exclusion criteria included maternal hypertension, autoimmune disorders, rupture of membranes, evidence of labor and drug use. RESULTS There were 59 women in the smoking and 66 in the non-smoking group. Compared to non-smoking mothers. maternal age was lower in smoking mothers with no significant difference in other demographic variables. There was no difference in levels of cytokines, anti-angiogenic factors and PlGF between the two groups. Median TGF-β1 levels were significantly higher in the smoking group (8120 pg/mL vs 6040 pg/mL, p < 0.001) and remained significant after controlling for confounders. TGF-β1 levels correlated positively with cotinine levels in the smoking group. CONCLUSIONS We speculate that higher TGF-β1 levels may explain the reduced incidence of preeclampsia in mothers who smoke by being available for action on maternal endothelium even after inactivation by circulating maternal sEng.

Abstract
Preeclampsia is a progressive hypertensive disorder of pregnancy affecting 2%-8% of pregnancies globally. Preexisting chronic hypertension is a major risk factor associated with developing preeclampsia, and growing evidence suggests a role for the gut microbiome in the development of preeclampsia. However, neither alterations in the gut microbiome associated with preeclampsia nor the mechanisms involved are fully understood. In this study, we tested the hypothesis that normal gestational maternal gut microbiome remodeling is impaired in the Dahl salt-sensitive (Dahl S) rat model of superimposed preeclampsia. Gut microbiome profiles of pregnant Dahl S, normal pregnant Sprague-Dawley (SD), and matched virgin controls were assessed by 16S rRNA gene sequencing at baseline; during early, middle, and late pregnancy; and 1-wk postpartum. Dahl S rats had significantly higher abundance in Proteobacteria, and multiple genera were significantly different from SD rats at baseline. The pregnant SD displayed a significant increase in Proteobacteria and genera such as Helicobacter, but these were not different between pregnant and virgin Dahl S rats. By late pregnancy, Dahl S rats had significantly lower α-diversity and Firmicutes compared with their virgin Dahl S controls. β-diversity was significantly different among groups (P < 0.001). KEGG metabolic pathways including those associated with short-chain fatty acids were different in Dahl S pregnancy but not in SD pregnancy. These results reveal an association between chronic hypertension and gut microbiome dysbiosis which may hinder pregnancy-specific remodeling in the gut microbial composition during superimposed preeclampsia.

Abstract
OBJECTIVE Preeclampsia (PE) and Metabolic syndrome (MetS) are multifactorial conditions and are major causes of maternal and neonatal morbidity and mortality worldwide. Both conditions are pro-inflammatory and can be causative factor for vascular damage. Anti-inflammatory mediators such as Resolvin also called resolution-phase interaction products may help to reduce the effect. Therefore, this study aimed to measure the serum Resolvin level in mild pre-eclamptic women with and without metabolic syndrome. MATERIAL AND METHODS A total of 293 pregnant females were recruited in this case control study. They were grouped as: Group A [pre-eclamptic patients with MetS (n = 140)] and Group B [pre-eclamptic patients without MetS (n = 153)]. Preeclampsia was diagnosed according to the ACOG criteria and metabolic syndrome according the NCEP-ATP III guidelines. Anthropometric data, lipid profile, Resolvin, VEGFR and PlGF levels were tested as per manufacturer's guidelines. Data was analyzed by using SPSS version 23. In all instances, a p value of <0.05 was considered significant. RESULTS All females were aged matched so no difference was observed in any group. Blood pressure and triglyceride levels were significantly higher in Group A; whereas VEGFR and PlGF were lower as compared to Group B. Higher Resolvin levels were observed in Group A subjects as compared to Group B [105.19 ± 42.29 pg/ml; 46.74 ± 20.16 pg/ml; p < 0.01 respectively]. Resolvin levels were found to have a weak correlation with BMI (r = 0.264; p = 0.11), while a positive strong correlation with systolic BP (r = 0.722; p < 0.001), diastolic BP (r = 0.664; p < 0.001) and a negative correlation with VEGFR (r = -0.639; p < 0.01) and PlGF (r = -0.523; p < 0.01). CONCLUSION Higher resolvin levels were observed in PE subjects with metabolic syndrome and showed a significant strong positive correlation with blood pressure. Further longitudinal studies are required to identify the causal link.

Cytokines, angiogenic, and anti-angiogenic factors are involved in the pathogenesis of preeclampsia. During normal pregnancy, Fas ligand (FasL) present on trophoblasts induces apoptosis of Fas bearing maternal immune cells. In preeclampsia, trophoblasts show increased apoptosis with reduced expression of FasL. We determined serum levels of cytokines, angiogenic (placental growth factor), anti-angiogenic factors (soluble endoglin, soluble fms-like tyrosine kinase-1), soluble Fas (sFas), and soluble FasL (sFasL) in smoking and non-smoking pregnant women. METHODS Using enzyme-linked immunosorbent and multiplex assays, we prospectively analyzed serum levels of angiogenic, anti-angiogenic factors, cytokines, sFas and sFasL in normotensive smoking and non-smoking mothers. Exclusion criteria included maternal hypertension, auto-immune disorders, rupture of membranes, evidence of labor, and drug use. RESULTS Of 100 women recruited to the study, 51 were in the non-smoking and 49 in the smoking group. Except for lower maternal age in the smoking group, there was no difference in gestation, BMI, gravidity, or ethnicity between the two groups. Levels of angiogenic, anti-angiogenic factors, cytokines, and sFas were similar between the two groups but sFasL levels were significantly higher in smoking group (38 pg/ml vs. 16 pg/ml, p < .001) and remained significant after controlling for confounders. CONCLUSION Our study demonstrates higher sFasL levels in pregnant women who smoke. Higher sFasL may explain the reduced incidence of preeclampsia in pregnant mothers who smoke by inducing apoptosis of immune cells which may otherwise induce trophoblast apoptosis.

J Cell Physiol 2020; 236:4435-4444. [PMID: 33184906 DOI: 10.1002/jcp.30160] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 10/25/2020] [Accepted: 11/03/2020] [Indexed: 12/11/2022]
Abstract
Recently, studies have shown that neuropathy target esterase (NTE) is essential to placental and normal blood vessel development. However, whether it is involved in abnormal placenta angiogenesis of pre-eclampsia remains unknown. Thus, our aim was to observe the expression of NTE in pre-eclamptic placentas and its effects and mechanism of NTE on the migration and the tube formation of human umbilical vein endothelial cells (HUVECs). Immunohistochemical staining showed that the NTE protein was intensely located in blood vessels of the normal pregnant placenta. However, western blot revealed that the expression level of NTE protein was significantly reduced in pre-eclamptic placenta. The results indicated that overexpression of NTE significantly promoted the migration and the tube formation of HUVECs compared with those of the control and scramble short hairpin RNA (shRNA) group. Conversely, NTE shRNA obviously inhibited the migration and the tube formation of HUVECs. Additionally, chromatography assay evidenced that NTE overexpression significantly reduced the level of phosphatidylcholine (PC) of HUVECs, but NTE shRNA obviously increased the level of PC of HUVECs. Furthermore, exogenous PC and lysophosphatidylcholine (LPC) significantly inhibited the tube formation of HUVECs in a dose-dependent manner. Collectively, our results suggest that reduced NTE in placenta may contribute to abnormal placenta angiogenesis of pre-eclampsia via the dysregulation of PC and LPC metabolism.

Abstract
The aim of this study was to investigate the effects and mechanisms of polyunsaturated fatty acids (PUFAs) and lipoxin A4 (LXA4) on preeclampsia (PE). The LXA4 level was significantly reduced in PE rats. The PUFA diet upregulated the expressions of lipoxygenase 12 (LOX12) and lipoxygenase 15 (LOX15) and downregulated those of cyclooxygenase-2, tumor necrosis factor-α (TNF-α), and endoglin. Lipopolysaccharides could inhibit cell growth and cause inflammatory response, while the presence of PUFAs inhibited the inflammatory response and promoted the expressions of LOX12, LOX15, and LXA4. Nordihydroguaiaretic acid (NDGA) regulated LXA4 expression and inflammation levels by affecting LOX. Inhibition of lipoxygenase 5 activity by NDGA upregulated the expressions of LOX12 and LOX15, while LXA4 reversed LXA4, nitric oxide downregulation, and TNF-α upregulation by NDGA. A decrease in LXA4 levels played an important role in the development and progression of PE.

Abstract
OBJECTIVE This study aimed to investigate the effects of melatonin on cardiac oxidative stress and apoptosis in the fetal heart in RUPP rats. METHODS The fetal heart samples were obtained from melatonin administrated RUPP rats. RESULTS Our results indicate that preeclampsia exacerbated by melatonin deficiency triggers hypoxic conditions, both mis/un-folded protein response, oxidative stress-induced DNA damage and apoptosis. Melatonin treatment provided significant therapeutic effects on fetal hearts via regulating all these stress response at cellular and molecular levels. CONCLUSION Melatonin may be considered as a potential molecule for development of preventive strategies to reduce the PE induced risk of cardiovascular diseases in offspring.

Abstract
The pathogenesis of preeclampsia (PE) involves several pathophysiological processes that may be affected by glucocorticoid (GC). We confirmed previously that GC exposure could result in PE, while PE is linked to a deficiency of lipoxin A4 (LXA4), an endogenous dual anti-inflammatory and proresolving mediator. The present study was to investigate whether GC exposure induces PE via dampening LXA4. In the study, cortisol levels of PE women were higher than those of normal pregnancies, LXA4 levels were downregulated in both PE patients and GC-mediated PE rats, and leukotriene B4 (LTB4) levels were upregulated in both PE patients and GC- mediated PE rats. Moreover, cortisol levels were negatively correlated to LXA4 levels, while positively correlated to LTB4 levels in PE patients. Mechanically, GC downregulated LXA4 via disturbing its biosynthetic enzymes, including ALOX15, ALOX5B and ALOX5, especially activating ALOX5, the key enzyme for class switching between LXA4 and LTB4. Importantly, replenishing LXA4 could ameliorate PE-related symptoms and placental oxidative stress in PE rat model induced by GC. Moreover, LXA4 could inhibit GC-mediated ALOX5 activation and LTB4 increase, and also suppress 11β-HSD2 expression and corticosterone upregulation. The protective actions of LXA4 might be explained by its roles in antagonizing the adverse effects of GC on trophoblast development. Together, our findings indicate that GC exposure could contribute to PE through dampening LXA4, and GC/LXA4 axis may represent a common pathway through which PE occurs.

Abstract
OBJECTIVE AND DESIGN The purpose of the review was to gather information on the role and possibilities of using lipoxin in the treatment of infertility and maintaining a normal pregnancy. Ovulation, menstruation, embryo implantation, and childbirth are reactions representing short-term inflammatory events involving lipoxin activities. Lipoxin A4 (LXA4) is an arachidonic acid metabolite, and in cooperation with its positional isomer lipoxin B4 (LXB4), it is a major lipoxin in mammals. Biosynthesis process occurs in two stages: in the first step, the donor cell releases the eicosanoid intermediate; secondarily, the acceptor cell gets and converts the intermediate product into LXA4 (leukocyte/platelet interaction). RESULTS Generating lipoxin synthesis may also be triggered by salicylic acid, which acetylates cyclooxygenase-2. Lipoxin A4 and its analogues are considered as specialized pro-resolving mediators. LXA4 is an important component for a proper menstrual cycle, embryo implantation, pregnancy, and delivery. Its level in the luteal phase is high, while in the follicular phase, it decreases, which coincides with an increase in estradiol concentration with which it competes for the receptor. LXA4 inhibits the progression of endometriosis. However, during the peri-implantation period, before pregnancy is confirmed clinically, high levels of LXA4 can contribute to early pregnancy loss and may cause miscarriage. After implantation, insufficient LXA4 levels contribute to incorrect maternal vessel remodeling; decreased, shallow trophoblastic invasion; and the immuno-energetic abnormality of the placenta, which negatively affects fetal growth and the maintenance of pregnancy. Moreover, the level of LXA4 increases in the final stages of pregnancy, allowing vessel remodeling and placental separation. METHODS The review evaluates the literature published in the PubMed and Embase database up to 31 December 2019. The passwords were checked on terms: lipoxin and pregnancy with combined endometriosis, menstrual cycle, implantation, pre-eclampsia, fetal growth restriction, and preterm labor. CONCLUSIONS Although no human studies have been performed so far, the cell and animal model study results suggest that LXA4 will be used in obstetrics and gynecology soon.

Abstract
Introduction: Change of circulating pentraxin-3 (PTX-3), a novel marker of inflammation, has been observed in women with preeclampsia (PE). However, results of previous studies were inconsistent. We performed a meta-analysis to evaluate the difference of circulating PTX-3 between women with PE and normal pregnancies.Methods: Case-control studies comparing circulating PTX-3 level between women with PE and normal pregnancies were identified via search of PubMed and Embase databases according to a predefined search strategy and inclusion criteria by two independent authors. Meta-analysis was performed with a random-effect model to incorporate heterogeneity.Results: Seventeen studies including 814 women with PE and 949 women with normal pregnancy were included. Results showed that women with PE had significantly higher circulating PTX-3 at diagnosis as compared to women with normal pregnancy (standardized mean difference [SMD]: = 1.74, 95% CI: 1.20-2.29, p < .001; I2 = 94%). The results were consistent regardless of study characteristics including study location, maternal age, sample size, early or late onset of PE, blood sample for PTX-3 measurement, or NOS quality scores. Moreover, higher circulating PTX-3 was also observed before the diagnosis of PE (SMD = 0.65, 95% CI: 0.02-1.29, p = .04; I2 = 87%).Conclusion: Women with PE have higher circulating PTX-3 than women with normal pregnancy. The elevated PTX-3 could be observed before the clinical onset of PE. Future studies are needed to determine whether PTX-3 is an active molecular in the pathogenesis of PE.

Abstract
The scientific background of perinatal pathology, regarding both mother and offspring, from the lipidomic perspective, has highlighted the possibility of identifying new, promising clinical markers of oxidative stress and inflammation, closely related to the normal development of unborn and newborn children, together with their application. In this regard, in recent years, significant advances have been achieved, assisted by both newly developed analytical tools and basic knowledge on the biological implications of oxylipins. Hence, in the light of this recent progress, this review aims to provide an update on the relevance of human oxylipins during pregnancy and in the unborn and newborn child, covering two fundamental aspects. Firstly, the evidence from human clinical studies and dietary intervention trials will be used to shed light on the extent to which dietary supplementation can modulate the lipidomic markers of oxidative stress and inflammation in the perinatal state, emphasizing the role of the placenta and metabolic disturbances in the mother and fetus. The second part of this article comprises a review of existing data on specific pathophysiological aspects of human reproduction, in relation to lipidomic markers in pregnant women, unborn children, and newborn children. The information reviewed here evidences the current opportunity to correct reproductive disturbances, in the framework of lipidomics, by fine-tuning dietary interventions.

Abstract
OBJECTIVE Abnormal changes in immune-mediated inflammation contribute to the pathogenesis of preeclampsia (PE). We aim to investigate the value of systemic immune inflammation indices-neutrophil-lymphocyte ratio (NLR) and monocyte-lymphocyte ratio (MLR)-to identify and evaluate the prognosis of patients with PE. METHODS This study reviewed clinical records of 367 PE patients (162 with mild PE and 205 with severe PE), in addition to a control group of 172 normal pregnancies. Blood cell counts were performed at the first diagnosis of PE, and NLR and MLR were calculated by absolute cell count. RESULTS Absolute neutrophil, lymphocyte, and monocyte counts and NLR and MLR values in PE were significantly different from controls, although monocyte counts did not significantly differ between mild and severe PE. Receiver operating characteristics curve (ROC) analysis showed NLR and MLR had better diagnostic accuracy in distinguishing PE from controls [NLR area under the curve (AUC) = 0.70; MLR AUC = 0.78]. Further, NLR was the best predictor of disease severity (AUC = 0.71). Cutoff values of NLR > 4.198 or MLR > 0.325 for control and PE groups or a cutoff value of NLR > 4.182 for PE groups indicated that patients were more likely to encounter preterm delivery, have shorter admission-to-delivery interval, and develop maternal and neonatal complications. CONCLUSION Secondary analyses of white blood cell differential count parameters effectively evaluate the systemic inflammatory/immune state. Compared with absolute cell counts, NLR and MLR offer more effective indicators of clinical assessment, disease severity evaluation, and prognosis evaluation of PE.

Abstract
Introduction Differential expression of genes encoding cytochrome P450 (CYP) and other oxygenases enzymes involved in biotransformation mechanisms of endogenous and exogenous compounds can lead to oral tumor development. Objective We aimed to identify the expression profile of these genes, searching for susceptibility biomarkers in oral squamous cell carcinoma. Patients and Methods Sixteen oral squamous cell carcinoma samples were included in this study (eight tumor and eight adjacent non-tumor tissues). Gene expression quantification was performed using TaqMan Array Human CYP450 and other Oxygenases 96-well plate (Applied Biosystems) by real time qPCR. Protein quantification was performed by ELISA and IHC methods. Bioinformatics tools were used to find metabolic pathways related to the enzymes encoded by differentially expressed genes. Results. CYP27B1, CYP27A1, CYP2E1, CYP2R1, CYP2J2, CYP2U1, CYP4F12, CYP4X1, CYP4B1, PTGIS, ALOX12, and MAOB genes presented differential expression in the oral tumors. After correction by multiple tests, only the PTGIS (Prostaglandin I2 Synthase) gene presented significant differential expression (P < 0.05). The PTGIS gene and protein were reduced in oral tumors. Conclusion PTGIS presents downexpression in oral tumors. PTGIS play an important role in the arachidonic acid metabolism. Arachidonic acid and/or metabolites are derived from this pathway, which can influence the regulation of important physiological mechanisms in tumorigenesis process.

Abstract
Preeclampsia (PE) in pregnancy is associated with vitrified-thawed embryo transfer. Pleiotrophin (PTN) is important in inflammation via its receptors. The aim of the present study was to determine the effect of PTN on the risk of PE following embryo transfer. An enzyme-linked immunosorbent assay was performed to determine the levels of tumor necrosis factor (TNF)-α and PTN in serum. The knockdown of PTN was conditionally induced by tamoxifen (tax) treatment. The tail-cuff method and Bradford assay were used to monitor blood pressure and the level of urine protein, respectively. The expression patterns of PTN, receptor protein tyrosine phosphatase β/ζ, (RPTPβ/ζ), syndecan-1 (SDC1), syndecan-3 (SDC3) and anaplastic lymphoma kinase (ALK) were determined by immunohistochemistry (IHC). Western blot analysis was performed to evaluate the expression level of PTN and its receptors. The risk of PE was elevated following embryo transfer in clinical and in the tax/PTN-/- group. It was found that the level of PTN increased when pregnancy progressed in normal conditions, however, the level of PTN was reduced in the PE mice. In addition, increases in TNF-α, blood pressure and urine protein were more marked in the PE mice that lacked PTN, compared with those in other PE mice. In addition, overlapping expression of PTN and its receptors in villous mesenchyme and fetal macrophages were identified using an IHC assay. However, the positive staining of PTN and its receptors was weaker or even absent in the PE mice. The protein level of RPTPβ/ζ was lower in the PE mice that lacked PTN than that in the other PE mice. The knockdown of PTN increased the risk of PE following vitrified-thawed embryo transfer, in which its receptors, particularly RPTPβ/ζ, may be involved.

The aim of the present study was to explore the possible relations of maternal serum and amniotic fluid nitric oxide (NO) and of vascular endothelial growth factor A (VEGF-A) concentrations with uterine artery Doppler indices (UtADs) in a healthy second trimester obstetric population. In this regard, the levels of NO and VEGF-A were measured in maternal sera and the amniotic fluid samples were in 36 subjects who were in their early second trimester of pregnancy. The mean levels for VEGF-A were 110.3 ± 31.5 pg/ml in maternal serum and 149.6 ± 31.3 pg/ml in amniotic fluid. Mean levels for NO were 5.7 ± 4.7 µmol in maternal serum and 12.9 ± 3.4 µmol in amniotic fluid. UtADs were measured concurrently with the sample collections. The mean value for uterine artery pulsatility index (PI) was 1.3 ± 0.4. The measurements were then analysed for possible correlations, whereby no correlation was found between UtAD and maternal serum levels of either molecule (p = .828 and p = .662 for VEGF-A and NO, respectively). However, a positive correlation was found between the NO levels in the amniotic fluid compartment and UtAD (r = 0.432, p = .009 for PI). Therefore, a correlation of UtAD with amniotic fluid NO can be expected in pregnancies with a normal outcome. Impact Statement What is already known on this subject? Nitric oxide (NO) and vascular endothelial growth factor A (VEGF-A) are important vasoactive molecules that play significant roles in early angiogenesis and placentation. What the results of this study add? There is a positive correlation between the amniotic fluid NO levels and the uterine artery Doppler indices (UtADs) in the second trimester of pregnancies with normal outcomes. What the implications are of these findings for clinical practice and/or future research? A correlation between amniotic fluid NO levels and UtAD may indicate a normal trophoblastic invasion. Disturbance of this balance may be expected in certain adverse pregnancy outcomes. Additional studies are needed to further explore the molecular signs of early abnormal placentation and their clinical reflection.

Abstract
The oviduct connects the ovary to the uterus, and is subject to changes that influence gamete transport, fertilization, and early embryo development. The ovarian steroids estradiol and progesterone are largely responsible for regulating oviduct function, although mating signals also affect the female reproductive tract, both indirectly, through sensory stimulation, and directly, through contact with seminal plasma or spermatozoa. The resulting alterations in gene and protein expression help establish a microenvironment that is appropriate for sperm storage and selection, embryo development, and gamete transport. Mating may also induce the switch from a non-genomic to a genomic pathway of estradiol-accelerated oviduct egg transport, reflecting a novel example of the functional plasticity in well-differentiated cells. This review highlights the physiological relevance of various aspects of mating to oviduct biology and reproductive success. Expanding our knowledge of the mating-associated molecular and cellular events in oviduct cells would undoubtedly facilitate new therapeutic strategies to treat infertility attributable to oviduct pathologies.

Abstract
During pregnancy, immune cells infiltrate the placenta at different stages of fetal development. NK cells and macrophages are the most predominant cell types. These immune cells play pleiotropic roles, as they control spiral artery remodeling to ensure appropriate blood supply and maintain long-term tolerance to a true allograft; yet, they must be able to mount appropriate immune defenses to pathogens that may threaten the fetus. Whether the same cell type accomplishes all these tasks or if there are dedicated subsets remains controversial. Here, we identify and characterize two distinct subsets of myeloid cells that differ in their pro-inflammatory/regulatory capacity. While one subset predominantly produces the immune-modulating cytokine IL-10, the second subset has superior capacity to secrete pro-inflammatory mediators, such as IL-1β and IL-6. The putative regulatory myeloid cells also express high levels of inhibitory receptors and their ligands, including programmed cell death 1 (PD1) ligands. Importantly, a large fraction of CD8 and CD4 cells in normal term human placenta are PD1 positive, suggesting that the PD1/PD1 ligands axis might be critical to maintain tolerance during pregnancy.

Abstract
Abdominal aortic aneurysm (AAA) is a chronic inflammatory condition, triggered by the local accumulation of macrophages, oxidative stress and damage to the aortic wall. Pro-inflammatory eicosanoids seem to play a significant role in AAA. The pro-inflammatory events seen in AAA could be due to a deficiency of anti-inflammatory eicosanoids such as lipoxin A4 (LXA4), resolvins, protectins and maresins as a result of reduced tissue concentrations of their precursors: arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Thus, an imbalance between pro- and anti-inflammatory eicosanoids may underlie AAA. Angiotensin-II (Ang-II), a pro-inflammatory molecule, seems to have a role in AAA. I propose that AAA is due to the local (abdominal aortic wall) deficiency of AA and other PUFAs and their anti-inflammatory metabolites especially LXA4. The beneficial action of EPA and DHA reported in the animal experimental models of AAA induced by Ang-II infusion can be attributed to their (EPA and DHA) ability to enhance the formation of not only resolvins, protectins and maresins but also LXA4. It is likely that abdominal aortic tissue (endothelial cells, smooth muscle cells and other cells) may be deficient in AA, EPA and DHA, and have defective activity of 5-, 12-, and 15-lipoxygenases and cyclooxygenase, especially COX-2 resulting in decreased formation of LXA4, resolvins, protectins and maresins. Thus, methods designed to enhance the formation of LXA4 and other anti-inflammatory eicosanoids may form a new approach to prevent and manage AAA.

Abstract
PURPOSE To compare serum humanin concentrations in pregnant women with and without pre-eclampsia (PE). MATERIALS AND METHODS A case-control study where pregnant women (PE group, n = 37; control group, n = 34) studied through history parameters (gynecological, obstetrical, personal, and family), physical and sonographic examination parameters [body mass index (BMI), blood pressure obstetrical ultrasound], and biochemical/hormonal assays [creatinine, urea, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), uric acid, platelets, urinary protein, and humanin]. RESULTS There was no difference in basic characteristics between women with PE and control, except in parity and gravidity. Humanin concentrations were higher in women with PE compared to controls (422.2 ± 33.5 vs. 319.1 ± 28.1 pg/ml, p = 0.023). In a binary logistic analysis, humanin was associated with the presence of PE [odds ratio 1.003, 95% confidence interval (CI); 1.000-1.006]. The ability of humanin to discriminate between women with PE and controls was evaluated by receiver operation characteristics (ROC) analysis [area under the curve (AUC) 0.639, 95% CI; 0.510-0.768, p = 0.045]. CONCLUSIONS Serum humanin concentrations are increased in women with PE, compared to women with uncomplicated pregnancies, suggesting a potential protective role of humanin against the oxidative stress and endothelial dysfunction occurring in PE.

Abstract
OBJECTIVE Preeclampsia (PE) is a disorder of pregnancy marked by hypertension and proteinuria with no known treatment aside from pregnancy termination. The pathogenesis of PE is poorly understood, but is thought to originate in the placenta. We assessed the value of measuring serum and urinary soluble deformylase-like tyrosine kinase receptor 1 (sFlt-1), a known target of placental factors, and placental growth factor (PLGF), a key placental signaling molecule, in the diagnosis of PE. METHODS Eighty patients with PE were classified as either exhibiting mild (44 cases) or severe (36 cases) symptoms of PE. Forty normal pregnant women were selected as controls. Serum and urinary PLGF and sFlt-1 levels, along with the ratio of sFlt-1 to PLGF, were compared across groups. RESULTS Serum and urinary sFlt-1 and sFlt-1/PLGF ratios in severe PE patients were significantly higher than those in the mild PE group, and measurements from mild PE patients were significantly higher than controls (all P values <0.01). The serum and urinary PLGF levels in severe PE patients were significantly lower than mild PE patients, and mild PE patients had significantly lower PLGF levels than controls (all P values <0.01). As expected, serum sFlt-1 and PLGF levels and ratios were highly correlated with urinary sFlt-1 and PLGF levels and ratios. CONCLUSIONS The severity of PE was closely correlated with these measurements, suggesting that they may be useful tools in the diagnosis and evaluation of PE.

Abstract
Despite the promising clinical outcome, the primary challenge of the curative cancer immunotherapy is to overcome the dichotomy of the immune response: tumor-evoked immunostimulatory versus tumor-induced immunosuppressive. The goal needs to be two-fold, to re-establish sustainable antitumor-cancer immunity and to eliminate immunosuppression. The successful elimination of cancer cells by immunosurveillance requires the antigenic presentation of the tumor cells or tumor-associated antigens and the expression of immunostimulatory cytokines and chemokines by cancer and immune cells. Tumors are heterogeneous and as such, some of the tumor cells are thought to have stem cell characteristics that enable them to suppress or desensitize the host immunity due to acquired epigenetic changes. A central mechanism underlying tumor epigenetic instability is the increased histone deacetylase (HDAC)-mediated repression of HDAC-target genes regulating homeostasis and differentiation. It was noted that pharmacological HDAC inhibitors are not effective in eliminating tumor cells partly because they may induce immunosuppression. We have shown that epithelial-specific tumor suppressor maspin, an ovalbumin-like non-inhibitory serine protease inhibitor, reprograms tumor cells toward better differentiated phenotypes by inhibiting HDAC1. Recently, we uncovered a novel function of maspin in directing host immunity towards tumor elimination. In this review, we discuss the maspin and maspin/HDAC1 interplay in tumor biology and immunology. We propose that maspin based therapies may eradicate cancer.
