MeSH terms

In summary, we show that pregnancy in the mouse is associated with a progressive increase in circulating IL6 levels, while hypothalamic Il6 and Il6ra expression are depressed. Lack of Prrgnancy increases respiratory exchange ratio in virgin mice In order to ascertain whether changes in energy expenditure or metabolic substrate preference RER in Il6 -KO mice could induce the subsequent fat accumulation during pregnancy, both parameters were analyzed by indirect calorimetry. During pregnancy adjustments are made to mother's homeostatic mechanisms that regulate food intake and the metabolism of nutrients [28][29].

Obese and GDM mothers have altered metabolism and hormone levels, including elevation of maternal circulatory lipids and pro-inflammatory cytokines. Objective: The goal of this study was to examine the associations of maternal weight status before, during, and after pregnancy with breast milk C-reactive protein CRP and interleukin 6 IL-6two bioactive markers of inflammation, measured at 1 interleeukin 3 months post partum. These results interleuin the hypothesis that IL-6 can disrupt the normal process of axon growth from NPY neurones, and suggest one possible mechanism for how the body weight regulating circuitry fails to develop properly in the offspring of obese dams. In conclusion, high levels of IL-6 stimulate trophoblast fatty acid accumulation, which could contribute to an excessive nutrient transfer in conditions associated with elevated maternal IL-6 such as obesity and gestational diabetes. Methods: Participants were exclusively breastfeeding mother-infant dyads taking part in the Mothers and Infants Linked for Health MILK study, who provided breast milk samples. Abstract Maternal obesity and gestational diabetes GDM are conditions associated with fetal overgrowth and excessive fat accumulation in the fetus, implicating an increased placental nutrient transfer in these pregnancies. When individuals undergo gestation in an obese dam, they are at increased risk for impairments in the ability of the brain to regulate body weight.

Relative fat mass values were calculated in percentage to maternal body weight middle panelexcluding the contribution of placentae and fetuses, and normalized to virgin control values of each genotype F. Clin Chim Acta. During each trimester, there may be various factors that modulate inflammatory reactions, where in the initial stage of pregnancy the pro-inflammatory effect is dominant, and in the second and third trimesters it evolves towards an anti-inflammatory state. As most of the newborns were delivered in good general condition, there were no statistically significant differences between the 2 groups. To do so, IL6 binds to its specific cell surface receptor IL6ra which has been found to be largely expressed in well-known hypothalamic centers for energy-balance regulation such as the PVN [27] and the ARC [54]. Low level of adiponectin is an independent predictor of gestational diabetes in obese women [ 1213 ], but there is no clear data on the role of adiponectin in the pathogenesis of pre-eclampsia or intrauterine growth restriction of the fetus [ 10 ]. These results are in agreement with previous reports showing that serum IL6 are elevated as early as gestational day 11 in the mouse [37].

Outside pregnancy, inteerleukin obesity and diabetes mellitus are associated with changes in inflammatory cytokines. Results The level of adiponectin in obese patients as compared to controls was significantly lower. IL6 is a pleiotropic immunomodulatory cytokine produced not only by the cells of immune system but also by cells in neuroendocrine and endocrine tissues, such as those in the hypothalamus, adipose tissue, skeletal muscle and reproductive organs [11]. Maternal cytokines were measured at 28 and 37 weeks gestation. In our study, gestational diabetes and hypertension were more common in the obesity group On the contrary, indications of an altered BAT thermogenic capacity of Il6 -KO pregnant mice were observed, suggesting that lack of Il6 might cause a decrease in energy expenditure during pregnancy. Nevertheless, another study on the role of adiponectin, leptin, and resistin in onset of pre-eclampsia showed only the influence of leptin and resistin [ 15 ].

Collectively, the results of the present study suggest a role of IL6 in the central homeostatic mechanisms that regulate body fat during pregnancy. In summary, we show that pregnancy in the mouse is associated interoeukin a progressive increase in circulating IL6 levels, while hypothalamic Il6 and Il6ra expression are depressed.

Centrally but not peripherally administered IL6 reduces adiposity mainly by increasing energy expenditure [14] and thermogenesis [52]and to a lesser extent by decreasing food intake [23]. Both groups of cells project to several brain areas such as the paraventricular nucleus PVN and lateral hypothalamic area LHA. This effect might contribute to a decreased sensitivity to the catabolic action of IL6 during this physiological state, as shown by increase fat accretion in Il6 -KO pregnant mice. Williams KW, Elmquist JK From neuroanatomy to behavior: central integration of peripheral signals regulating feeding behavior. To explore the role of IL6 in the central mechanisms governing dam's energy homeostasis, early, mid and late pregnant gestational days 7, 13 and 18 wild-type WT and Il6 knockout mice Il6- KO were compared with virgin controls at diestrus. Additional mechanisms might include a decrease in energy expenditure in pregnant Il6 deficient mice in comparison to WT controls as a result of an altered BAT functionality. Western-blots were performed as previously described [44].

Surprisingly, knockout of Il6 in late pregnant animals did not affect the hypothalamic expression of its receptor, probably reflecting a local compensatory mechanism exerted by other cytokines. PLoS One 8: e Inflammation and miscarriage. Protein levels were normalized to alpha-tubulin for each sample and expressed in percentage respect to the average value of the WT virgin control group.

Maternal adiposity was assessed indirectly by calculating the Body Mass Index BMIand directly by bioelectrical impedance analysis. Neuroscientist 8: — The p-values below pgegnancy. The study included 40 women with body mass index BMI less than 30 and 24 pregnant women with BMI equal to or greater than 30, admitted to the Perinatology and Obstetrics Department of the University Hospital in Cracow in the first stage of labor. Abstract Outside pregnancy, both obesity and diabetes mellitus are associated with changes in inflammatory cytokines. However, in accordance to a stimulatory effect of IL6 whether of central or peripheral origin on hypothalamic Il6ra mRNA levels, we report that lack of Il6 in mid-pregnant animals markedly diminishes its receptor gene expression. Nevertheless, another study on the role of adiponectin, leptin, and resistin in onset of pre-eclampsia showed only the influence of leptin and resistin [ 15 ].

Serum saturated fatty acid decreases plasma adiponectin and increases leptin throughout pregnancy independently of BMI. As a significant overall effect of genotype was detected, a Bonferroni post-test was applied for the pairwise comparison e. Increased respiratory exchange ratio in Il6 -KO mice.

Results Il6-KO mice show ajd weight gain and fat mass but higher fat accretion than WT mice during pregnancy Firstly, we studied the effect of lack of endogenous Il6 in the pregnancy-related changes on body weight Figure 1A. Healthy women with a singleton pregnancy and a normal glucose tolerance test at 28 weeks gestation were enrolled at their convenience. Whether IL6 of both origins plays distinct or parallel functions in a coordinate manner during chronic or acute inflammatory conditions has yet to be established. Increased respiratory exchange ratio in Il6 -KO mice. PLoS One 8: e

Blood samples were taken from patients to detect the serum concentration of cytokines. Linear regression analysis was used to detect the association. Nat Rev Neurosci 9: 11— Slides were allowed to acclimate to room temperature for approximately 10—15 min prior to staining.

Abstract Maternal obesity and gestational diabetes GDM are conditions associated with fetal overgrowth and excessive fat accumulation in the fetus, implicating an increased placental nutrient transfer in these pregnancies. In rodents, gestation in an obese dam leads to a number of changes to the development of the hypothalamic neurones that regulate body weight, including reduced neuronal connectivity at birth.

No associations were observed for IL The increased fatty acid accumulation could not be explained by an increased expression of key components in placental fatty acid transport, such as adipophilin, fatty acid transport protein FATP 1, FATP4, or lipoprotein lipase. We then used this model to test 2 hypotheses: i ARN NPY neurones respond to Netrin-1, one of a small number of axon growth and guidance factors that regulate neural circuit formation throughout the developing brain; and ii Netrin-1 responsiveness would be lost upon exposure to the inflammatory cytokine interleukin IL -6, which is elevated in foetuses developing in obese dams. When individuals undergo gestation in an obese dam, they are at increased risk for impairments in the ability of the brain to regulate body weight. Linear regression was used to examine the associations of maternal weight status with repeated measures of breast milk CRP and IL-6 at 1 and 3 months, after adjustment for potential confounders. We observed that ARN NPY neurones responded to Netrin-1 with a significant expansion of their growth cones, comprising the terminal apparatus that neurones use to navigate.

Ultrasound was used to evaluate the development of the fetus, including estimated fetal weight, Doppler flows, and the amount of amniotic fluid. Clin Chim Acta. The results presented in this study are mostly consistent with previous reports [ 33 ]. Within the hypothalamus, two functionally opposing subpopulations of neurons in the arcuate nucleus ARC represent a key integrative site for these signals. It was shown that in obesity, there is reduced adiponectin expression due to increased DNA methylation and negative feedback signals transmitted through the adiponectin receptors in various tissues, including the placenta [ 11 ].

In conclusion, high levels of IL-6 stimulate trophoblast fatty acid accumulation, which could contribute to an excessive nutrient transfer in conditions associated with elevated maternal IL-6 such as obesity and gestational diabetes. We observed that ARN NPY neurones responded to Netrin-1 with a significant expansion of their growth cones, comprising the terminal apparatus that neurones use to navigate. Methods: Participants were exclusively breastfeeding mother-infant dyads taking part in the Mothers and Infants Linked for Health MILK study, who provided breast milk samples. Finally, we observed that IL-6 treatment of normal NPY neurones in vitro led to a reduced growth cone responsiveness to Netrin-1, essentially causing them to behave similarly to NPY neurones from obese pregnancies. First, we developed an in vitro model for observing and manipulating the axonal growth of foetal arcuate nucleus ARN neuropeptide NPY neurones. The increased fatty acid accumulation could not be explained by an increased expression of key components in placental fatty acid transport, such as adipophilin, fatty acid transport protein FATP 1, FATP4, or lipoprotein lipase.

Multiple onterleukin analysis was used to access the effect of age, week of pregnancy, and previous miscarriages on the level pregmancy inflammatory mediators. PLoS One 8: e In addition to its peripheral production, IL6 is also synthesized in the nervous system with cellular sources being neurons, astrocytes and microglia, which are recruited to produced this cytokine in response to different immunogenic stimulus including LPS endotoxemia [57]but also in response to overnutrition and obesity [56]. BMC Pregnancy Childbirth. Despite the high level of co-expression of Trh and Il6ra in the mouse hypothalamus [27]published data do not support a role of IL6 as a direct modulator of Trh gene transcription [67]. Afferent endocrine signals encoding energy status may arise from different sites including: i fat, which secretes adipokines such as leptin, adiponectin, resistin and interleukin-6 IL6ii pancreas, which produces insulin and iii gastrointestinal organs, which release hormones such as ghrelin, glucagon-like peptide I and peptide YY [1][4][5].

Abstract Objective: The goal of this study was to examine the associations of maternal weight status before, during, and after pregnancy with breast milk C-reactive protein CRP and interleukin 6 IL-6two bioactive markers of inflammation, measured at 1 and 3 months post partum. Obese and GDM mothers have altered metabolism and hormone levels, including elevation of maternal circulatory lipids and pro-inflammatory cytokines. These results support the hypothesis that IL-6 can disrupt the normal process of axon growth from NPY neurones, and suggest one possible mechanism for how the body weight regulating circuitry fails to develop properly in the offspring of obese dams.

Obese and GDM mothers have altered metabolism interlehkin hormone levels, including elevation of maternal circulatory lipids and pro-inflammatory pbesity. We then used this model to test 2 hypotheses: i ARN NPY neurones respond to Netrin-1, one of a small number of axon growth and guidance factors that regulate and pregnancy circuit formation throughout the developing brain; and ii Netrin-1 responsiveness would be lost upon exposure to the inflammatory cytokine interleukin IL -6, which is elevated in foetuses developing in obese dams. Abstract When individuals undergo gestation in an obese dam, they are at increased risk for impairments in the ability of the brain to regulate body weight. Unexpectedly, we found further that NPY neurones from obese pregnancies had a reduced responsiveness to Netrin-1, raising the possibility that ARN NPY neurones from foetuses developing in obese dams were phenotypically different from normal NPY neurones. Linear regression was used to examine the associations of maternal weight status with repeated measures of breast milk CRP and IL-6 at 1 and 3 months, after adjustment for potential confounders.

The role of cytokines as inflammatory mediators in preeclampsia. Introduction Energy balance is largely regulated by the central nervous system CNS via a homeostatic system. Neurosci Behav Physiol — Animals were time pregnant and on the corresponding date of pregnancy were anesthetized, and after collection of serum samples by cardiac puncture, were sacrificed by decapitation.

Figure 1. In this study, we did not show a correlation between cerebroplacental ratio and the markers of inflammation, and the literature does not provide any objective evidence of this. The level of adiponectin was significantly lower in obese patients than in patients with normal BMI. Currently, there are no reference levels of cytokines for either physiological pregnancy or pregnancy in obese patients. Obesity during pregnancy alters maternal oxidant balance and micronutrient status. The ultrasound examination was performed to evaluate the development of the fetus, including growth profile, evaluation of Doppler flow in the umbilical artery, Doppler flow in the middle cerebral artery with calculation of the cerebroplacental ratio CPRDoppler flow in uterine arteries, and the amniotic fluid index.

  • Measuring other inflammatory markers, such as leptin or resistin, may also be helpful, as there are data showing an important correlation with outcomes in pregnancies complicated by obesity [ 3435 ]. This was an observational study, conducted in a group of 64 adult women in the third trimester of pregnancy during the perinatal period, admitted to the Department of Obstetrics and Perinatology University Hospital in Cracow in the period from August to June

  • In conclusion, high levels of IL-6 stimulate trophoblast fatty acid accumulation, which obesity and pregnancy contribute to an excessive nutrient transfer in conditions associated with elevated maternal IL-6 such as obesity and gestational diabetes. Unexpectedly, we found further that NPY neurones from obese pregnancies had a reduced responsiveness to Netrin-1, raising the possibility that ARN NPY neurones from foetuses developing in obese dams were phenotypically different from normal NPY neurones.

  • Average values of RER as well as body weight and lean mass corrected energy expenditure are shown in right panels. Background Obesity is a major clinical problem, affecting a large number of people.

San Diego: Academic Press. It has anti-inflammatory and antiatherogenic effects and increases insulin sensitivity. The exact role interlejkin inflammation in pregnancy is not well understood. Faldt et al [26] but also Wernstedt et al [13] observed that pre-obese Il6 deficient mice had a higher RER than their WT controls, indicating a preferential oxidation of carbohydrates vs fat, which has been postulated as a mechanism behind the subsequent development of obesity in this mouse model.

Investigation of systemic inflammatory response in first trimesterpregnancy failure. In this study, we did not show a correlation between cerebroplacental ratio and the markers of inflammation, and the literature does not provide any objective evidence of this. During pregnancy adjustments are made to mother's homeostatic mechanisms that regulate food intake and the metabolism of nutrients [28][29].

Whether IL6 of pregnxncy origins plays distinct or parallel functions in a coordinate manner during chronic or acute inflammatory conditions has yet to be established. A decreased fat utilization in absence of Il6 might explain this effect, as shown by increased respiratory exchange ratio RER in virgin Il6 -KO mice. View Article Google Scholar 8. J Perinatol.

Competing interests: The authors have declared that no competing interests exist. For the neonatal ppregnancy, there were pregnancy factor taken into consideration: Apgar score and fetal birth weight. Relative fat mass values were calculated in percentage to maternal body weight middle panelexcluding the contribution of placentae and fetuses, and normalized to virgin control values of each genotype C. Am J Reprod Immunol. Nat Med 8: 75— Open in a separate window. Obesity in pregnancy.

There was no statistically significant relationship between IL-6 p-vale 0. Age matched female WT and Il6 -KO mice 12—15 weeks old were always used and allocated to either virgin unmated or pregnant groups prior to the start of the experiments. PLoS One 7: e Obstet Gynecol Surv.

Fetal adiposity was assessed by ultrasound measurement of fetal soft tissue markers and by birthweight at delivery. J Obstet Gynaecol. Med Sci Monit. Figure S2. Several studies point to a role of IL6 system as a key pathway involved in the central regulation of energy balance. Nat Med —

The results of previous reports show that in obese patients, serum levels of these adipocytokines are increased during pregnancy due to the influence of increased BMI [ 16 — 18 ]. Il6 mRNA levels were similar in adipose tissue of virgin and 7 days pregnant WT mice, but increased three fold on gestational days 13 and 18 Figure 5Apercentage of WT virgin values at gestational days 13 and Mice were acclimated for 48 hr to the test chambers and then were monitored for an additional 24 hr. Central Il6ra gene expression is known to be activated in response to systemic immune challenges such as intravenous injections of lipopolysaccharide LPS or the pro-inflammatory cytokine interleukin-1 IL1but also in response to IL6 itself [57][58]. Materials and Methods Animals B6. To do so, IL6 binds to its specific cell surface receptor IL6ra which has been found to be largely expressed in well-known hypothalamic centers for energy-balance regulation such as the PVN [27] and the ARC [54].

Abstract Maternal obesity and gestational diabetes GDM are conditions associated with fetal overgrowth and excessive fat accumulation in the fetus, implicating an increased placental nutrient transfer in these pregnancies. When individuals undergo gestation in an obese dam, they are at increased risk and pregnancy impairments in the ability of the brain to regulate body weight. Finally, we observed that IL-6 treatment of normal NPY neurones in vitro led to a reduced growth cone responsiveness to Netrin-1, essentially causing them to behave similarly to NPY neurones from obese pregnancies. Unexpectedly, we found further that NPY neurones from obese pregnancies had a reduced responsiveness to Netrin-1, raising the possibility that ARN NPY neurones from foetuses developing in obese dams were phenotypically different from normal NPY neurones.

Abstract When individuals undergo gestation in an obese dam, they are at increased risk for impairments in the ability of the brain to regulate body weight. The increased fatty acid accumulation could not be explained by an increased expression of key components in placental fatty acid transport, such as adipophilin, fatty acid transport protein FATP 1, FATP4, or lipoprotein lipase. Abstract Maternal obesity and gestational diabetes GDM are conditions associated with fetal overgrowth and excessive fat accumulation in the fetus, implicating an increased placental nutrient transfer in these pregnancies. In rodents, gestation in an obese dam leads to a number of changes to the development of the hypothalamic neurones that regulate body weight, including reduced neuronal connectivity at birth.

IL6 is a pleiotropic immunomodulatory cytokine interleuin not only by the cells interlekin immune system but also by cells in neuroendocrine and endocrine tissues, such as those in the hypothalamus, adipose tissue, skeletal muscle and reproductive organs [11]. We also investigated whether the putative effects of endogenous IL6 could be mediated by changes in hypothalamic Il6ra expression during this physiological state. Vallieres L, Rivest S Interleukin-6 is a needed proinflammatory cytokine in the prolonged neural activity and transcriptional activation of corticotropin-releasing factor during endotoxemia. The PVN acts as a primary integrative center for peripheral cytokine signaling to CNS and stimulation of a variety of physiological, neuroendocrine and behavioral CNS responses including: suppression of food intake, thermogenesis and HPA axis activation [7]. Inflammation in maternal obesity and gestational diabetes mellitus. Therefore, better understanding of the effect of obesity on pregnancy is of great clinical importance. The mean number and weight of embryos and placentae in uteri of days pregnant mice were also similar between genotypes, as were the litter sizes and the weight of newborn mice at birth Table S2 in File S2.

Biochem Biophys Res Commun — As previously reported [26]we observed that Il6 -KO female mice had lower body weight than WT mice due to a decrease in fat but not in lean body mass, body length or relative food intake. Lean body mass of virgin and pregnant WT and Il6-KO mice at the beginning gestational day 7 and the end of the experimental period gestational day 18 as expressed in an absolute A or a relative to weight basis B. Anabolic and orexigenic peptides: neuropeptide Y Npy and agouti-related peptide Agrp ; and catabolic and anorectic neuropeptides: proopiomelanocortin Pomccorticotrophin and thyrotropin-releasing hormone Crh and Trh mRNA levels were determined by in situ hybridization.

Linear regression was used to examine the associations of maternal weight status with repeated measures of breast milk CRP and IL-6 at 1 and 3 months, after adjustment for potential confounders. The consequences of infants receiving varying concentrations of breast milk inflammatory markers are unknown; however, it is speculated that there are implications for the intergenerational transmission of disease risk. No associations were observed for IL

  • The risk of maternal obesity to the long-term health of the offspring.

  • Abstract When individuals undergo gestation in an obese dam, they are at increased risk for impairments in the ability of the brain to regulate body weight. Pre-pregnancy body mass index BMI and gestational weight gain GWG were assessed by chart abstraction; postpartum weight loss was measured at the 1- and 3-month study visits.

  • Multiple regression analysis was used to access the effect of age, week of pregnancy, and previous miscarriages on the level of inflammatory mediators. The functional relevance of ihterleukin Trh transcriptional modulation during mid-pregnancy remains to be determined but, considering the important role of this neuropeptide in the regulation of energy homeostasis and its central effects on thermogenesis [8]a role as triggering signal of the increase in maternal basal metabolic rate seen in the latter stages of mouse pregnancy [66] might be hypothesized.

Serum saturated fatty acid decreases plasma adiponectin and increases leptin throughout pregnancy independently of BMI. Footnotes Source of support: Departmental sources. Transversal analysis of specific fat depots and sample collection for subsequent expression studies by real-time quantitative RT-PCR were performed in 12 weeks old mice. Results The study included women at 37—41 weeks of pregnancy median 39 weeksages 19—47 years median 31 yearswho had singleton pregnancies. A final issue to take into account when considering the findings of the present study is the possible source of experimental variability induced by the homozygous breeding scheme used to generate the experimental animals.

A standard curve was run in each assay, with an arbitrary value assigned to the highest standard and corresponding values to the subsequent dilutions. To compare anatomically similar regions, slides were matched according to the mouse atlas of Franklin and Paxinos [43]. Source of support: Departmental sources. Ginekol Pol. Moreover, excessive maternal weight is a risk factor for long-term complications in the newborn [ 67 ]. Detailed observation of the Il6 -KO mice phenotype at young and late ages has been performed in several previous studies.

A study reported a significant negative correlation between oxidative stress markers and adiponectin, suggesting a relationship between antioxidant levels interleukin 6 obesity and pregnancy this adipokine in healthy pregnancies, which is altered in patients with gestational hypertension or pre-eclampsia [ 14 ]. This option seems plausible in light of the decreased UCP3 levels and the accumulation of lipid droplets observed in the BAT of Il6 -KO mice at mid pregnancy, which suggests a reduction in the BAT thermogenic program in our model [55]. Within the hypothalamus, two functionally opposing subpopulations of neurons in the arcuate nucleus ARC represent a key integrative site for these signals. Age matched female WT and Il6 -KO mice 12—15 weeks old were always used and allocated to either virgin unmated or pregnant groups prior to the start of the experiments. Serum adiponectin in gestational diabetes and its relation to pregnancy outcome.

Lack of Il6 in mice differentially modulates the gestational transcriptional profile of energy balance regulating peptides at the level of the ARC and PVN, with mayor stimulatory and inhibitory effects on AgrpNpy and Pomc as well as Trh gene expression during mid- and late-pregnancy.
