Human milk (HM) is the golden standard for nutrition of newborn infants. Human milk oligosaccharides (HMOs) are abundantly present in HM and exert multiple beneficial functions, such as support of colonization of the gut microbiota, reduction of pathogenic infections and support of immune development. HMO-composition is during lactation continuously adapted by the mother to accommodate the needs of the neonate. Unfortunately, for many valid reasons not all neonates can be fed with HM and are either totally or partly fed with cow-milk derived infant formulas, which do not contain HMOs...

Zika virus (ZIKV) is a mosquito-borne flavivirus associated with severe neonatal birth defects, but the causative mechanism is incompletely understood. ZIKV shares sequence homology and early clinical manifestations with yellow fever virus (YFV) and dengue virus (DENV) and are all transmitted in urban cycles by the same species of mosquitoes. However, YFV and DENV have been rarely reported to cause congenital diseases. Here, we compared infection with a contemporary ZIKV strain (FSS13025) to YFV17D and DENV-4 in human monocytic cells (THP-1) and first-trimester trophoblasts (HTR-8)...

The transcription factor MAFB is an important regulator of the development and differentiation of various organs and tissues. Previous studies have shown that MAFB is expressed in embryonic and adult mouse testes and is expected to act as the downstream target of retinoic acid (RA) to initiate spermatogenesis. However, its exact localization and function remain unclear. Here, we localized MAFB expression in embryonic and adult testes and analyzed its gene function using Mafb-deficient mice. We found that MAFB and c-MAF are the only large MAF transcription factors expressed in testes, while MAFA and NRL are not...

: The current study is performed to assess a routine for treatment of immune thrombocytopenic purpura in pregnancy. A prospective programme for monitoring and treatment with intravenous immunoglobulin or cortisone in pregnancies with immune thrombocytopenic purpura was suggested to all delivery units in Sweden. Treatment should be avoided if platelet counts were more than 20 × 10/l during pregnancy with no bleeding complications and with a target of 100 × 10/l at delivery. Descriptive statistics and logistic regression analysis were used...

Enterovirus D68 (EV-D68) has been increasingly associated with severe respiratory illness and neurological complications in children worldwide. However, no vaccine is currently available to prevent EV-D68 infection. In the present study, we investigated the possibility of developing a virus-like particle (VLP)-based EV-D68 vaccine. We found that co-expression of the P1 precursor and 3CD protease of EV-D68 in Pichia pastoris yeast resulted in the generation of EV-D68 VLPs, which were composed of processed VP0, VP1, and VP3 capsid proteins and were visualized as ~30 nm spherical particles...

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder occurring in 1:10,000-1:20,000 live births. In >95% of the cases, CAH results from mutations in the CYP21A2 gene, encoding the adrenal steroid enzyme 21-hydroxylase (21OH). Cardinal phenotypic features of CAH include genital ambiguity and sexual precocity, and in severe cases, neonatal salt loss and death. Current standard of care consists of life-long oral steroid replacement to reverse the cortisol deficiency. Although significant advances in the treatment of CAH have been made, the burden of a life-long therapeutic intervention is not ideal for quality of life...

Preterm birth is widespread and causes 35% of all neonatal deaths. Infants who survive face potential long-term complications. A major contributing factor of preterm birth is infection. We investigated the role of Interleukin 22 (IL22) as a potential clinically relevant cytokine during gestational infection. IL22 is an effector molecule secreted by immune cells. While the expression of IL22 was reported in normal non-pregnant endometrium and early pregnancy decidua, little is known about uterine IL22 expression during mid- or late gestational stages of pregnancy...

Zika virus (ZIKV) has recently caused a pandemic disease, and many cases of ZIKV infection in pregnant women resulted in abortion, stillbirth, deaths and congenital defects including microcephaly, which now has been proposed as ZIKV congenital syndrome. This study aimed to investigate the in situ immune response profile and mechanisms of neuronal cell damage in fatal Zika microcephaly cases. Brain tissue samples were collected from 15 cases, including 10 microcephalic ZIKV-positive neonates with fatal outcome and five neonatal control flavivirus-negative neonates that died due to other causes, but with preserved central nervous system (CNS) architecture...

BACKGROUND: In fetal and neonatal alloimmune thrombocytopenia (FNAIT), maternal alloantibodies directed against paternally-derived platelet antigens are transported across the placenta to the fetus, where they may cause thrombocytopenia. The most serious complication of FNAIT is an intracranial hemorrhage (ICH), which may cause death or life-long disability of the child. Apart from alloantibody-mediated platelet destruction, the clinical outcome in FNAIT may be affected by properties of neonatal platelets and possible functional effects on platelets caused by maternal alloantibodies...

BACKGROUND: Exposure of the developing brain to immune mediators, including antibodies, is postulated to increase risk for neurodevelopmental disorders and neurodegenerative disease. It has been suggested that immunoglobulin G-immune complexes (IgG-IC) activate Fc gamma receptors (FcγR) expressed on neurons to modify signaling events in these cells. However, testing this hypothesis is hindered by a paucity of data regarding neuronal FcγR expression and function. METHODS: FcγR transcript expression in the hippocampus, cortex, and cerebellum of neonatal male and female rats was investigated ex vivo and in mixed cultures of primary hippocampal and cortical neurons and astrocytes using quantitative PCR analyses...

Introduction: Health indicators of rural and urban India show a wide variation. Rural areas have received large focus in child health services, but on the flip side, urban areas have been the last to receive such attention. Materials and Methods: A cross-sectional study was conducted to include one randomly selected outreach session from all the 19 urban primary health centers of Vadodara city from April 2013 to May 2014. Nineteen session sites were observed for the process evaluation of three components of child health care, namely, "planning of Health and Nutrition Day," "availability of vaccines/logistics," and "direct observation of actual immunization process" at the site using a structured checklist...

Background: Achieving World Health Organization (WHO) recommendations for postnatal care (PNC) within the first few weeks of life is vital to eliminating early mother-to-child transmission of HIV (MTCT) and improving infant health. Almost half of the annual global deaths among children under five occur during the first six weeks of life. This study aims to identify uptake of three PNC visits within the first six weeks of life as recommended by WHO among South African mother-infant pairs, and factors associated with uptake...

Porcine epidemic diarrhea virus (PEDV) poses a serious threat to swine worldwide as evidenced by its recent introduction into the USA and the devastating economic impact it caused to the USA swine industry. Commercial vaccines against PEDV are available but their efficacies are inadequate. Therefore, vaccines with improved efficacy are needed to effectively control PEDV infections. We previously determined the immunogenicity of a novel dendritic cell (DC)-targeted PEDV S1 protein-based subunit vaccine in weaned piglets in which the PEDV antigen was targeted to DCs through a porcine Langerin-specific antibody...

Extremely preterm infants are at high risk for morbidities including bronchopulmonary dysplasia, intraventricular hemorrhage, and retinopathy of prematurity likely related to their exposure to reactive oxygen and nitrogen species early in life. Selenium is a trace mineral contributes to the proper function of multiple systems including immunity, redox regulation, and inflammation via the "selenoenzymes" glutathione peroxidase, thioredoxin reductase, and selenoprotein P. Given that selenium accretion via the placenta occurs primarily during the third trimester, preterm neonates are born selenium deficient...

Enterovirus D68 (EV-D68) is increasingly associated with severe acute respiratory infection and acute flaccid myelitis (AFM) in children around the world. However, neither vaccines nor therapeutic drugs are available for EV-D68. Here we report the development of a virus-like particle (VLP) based experimental EV-D68 vaccine. We found that EV-D68 VLPs could be successfully generated in insect cells infected with a recombinant baculovirus co-expressing the P1 precursor and 3CD protease of EV-D68. Biochemical and electron microscopic analyses revealed that EV-D68 VLPs were composed of VP0, VP1, and VP3 capsid proteins derived from precursor P1 and were visualized as spherical particles of ∼30 nm in diameter...

In adult hematopoiesis, the hematopoietic stem cell (HSC) sits at the top of a hierarchy of hematopoietic progenitors responsible for generating the diverse repertoire of blood and immune cells. During embryonic development, however, the initial waves of hematopoiesis provide the first functioning blood cells of the developing embryo, such as primitive erythrocytes arising in the yolk sac, independently of HSC. In the field of developmental immunology, it has been recognized that some components of the immune system, such as B-1a lymphocytes, are uniquely produced during the embryonic and neonatal period, suggesting a "layered" development of immunity...

Neutrophil gelatinase-associated lipocalin (NGAL) and lactoferrin (Lf) are among the key components of the innate immune system due to their ability to bind iron with high affinity and thus control inflammation. The aim of this study was to test the use of NGAL and LF measurements in meconium for the assessment of the intrauterine homeostasis. NGAL and Lf concentrations were measured using ELISA kits in all serial meconium portions (n = 81) collected from 20 healthy neonates. Mean ± SD meconium concentration of Lf was 45...

BACKGROUND: Endothelial cells (ECs) exert immunological functions such as production of proinflammatory cytokines/chemokines as well as facilitation of extravasation of immune cells into infected tissue. Limited data are available on the functionality of ECs from extremely preterm neonates during infection. Accordingly, the aim of our study was to investigate the immune response of premature ECs after proinflammatory stimulation. METHODS: Cell adhesion receptors expression and function, NFkB-signaling and chemokine production were analyzed in umbilical cord ECs from extremely preterm and term neonates after proinflammatory stimulation...

OBJECTIVE: Erythrocyte allo-immunization's rate has decreased but without adapted treatment the prognosis is still poor. The aim of our study was to evaluate the fetal prognosis, the complication's rate and the risk factors of complications of the intrauterine transfusion. METHODS: Retrospective study about 37 fetus and 86 intrauterine transfusions between 2001 and 2017. Our main criterion in judging was the occurrence of procedure related complications: premature membrane rupture or premature delivery within seven days from the procedure, chorioamnionitis, abnormal fetal heart rate indicating an emergency ceasarean section within the 24hours from the procedure, in utero death or neonatal death related to the procedure...
