Clinical Research Unit 296 ‘Feto-maternal immune cross talk’

During pregnancy, the maternal immune system develops immunological tolerance to the fetus. This immunological tolerance arises from the intense dialogue of pregnancy hormones and immune cells and contributes to a complication-free course of pregnancy until the birth of the child. Significant benefits to the health of the mother are associated with mounting immunological tolerance, such as a mitigation of maternal autoimmune diseases. On the other hand, pregnant women are at a significant health disadvantage because they have a high susceptibility to infection, for example towards the influenza virus.

Challenges during pregnancy, such as infections, but also maternal stress and use of medication, may confer disadvantages to children's health later in life.

In the Clinical Research Unit 296, which is represented by Petra Arck as a speaker, includes physicians and basic researchers from a variety of medical disciplines, aims to understand the mechanisms underlying the health advantages and disadvantages for mother and child originating during pregnancy.

A successful pregnancy is associated with a significantly reduced risk of complications in subsequent pregnancies. Biological processes that contribute to this reduced risk of pregnancy complications are currently unknown. In the present project, we aim to identify immune markers through which this reduced risk of complications in subsequent pregnancies is mediated. We expect that the findings from the proposed project will allow us to form a solid basis for the development of diagnostic markers and therapeutic approaches, with the aim of improving the chances of a healthy (first) pregnancy.

Long-term programming of sex differences in immunity by prenatal exposure to stress 

DFG-logo-blau.svg.png
DFG-logo-blau.svg.png

Prenatal adverse environments including the exposure to stress adversely program immunity later in life. Hereby, significant sex differences in childhood- and adult-onset immune disorders have been observed, which can perpetuate or reverse instinctive sex-specific immune responses. We here investigate how fetal exposure to prenatal glucocorticoid surges differentially modulates long-term immunity later in life of male and female offspring. We will provide insights on the degree of control of viral infections and tumor growth in male and female offspring challenged by an adverse prenatal environment.

ONGOING RESEARCH

Reducing the infection risk in children: understanding the trajectories of maternal and childhood vaccinations (REINFORCE):

_edited.jpg
REINFORCE_2.png
REINFORCE_1.png

The risk for childhood infections is greatly dependent on the complex interaction between maternal levels of antibodies during pregnancy, the order and response to childhood vaccinations, the sex of the child and the environment. In the present proposal, we seek to establish an international collaboration between experts in the field of early life infections based in Copenhagen and Hamburg in order to evaluate the trajectories of maternal and child vaccinations and early life infections in Norther European countries.

 

This network is funded by the Authority for Science, Research and Equality, Hamburg, Germany within the program to promote collaboration among research institutions located near the Baltic Sea

Research Network FV73 ‘Pregnancy, immunity and health risks in mother and child’ 

_edited.jpg

Pregnancy can be considered as a blueprint for understanding the immune response to infections and neuro-immunological cross talk. This research network expands is coordinated by Petra Arck as a speaker and links the repertoire of diseases addressed in the CRU 296.

In individual subprojects, we here investigate the pathogenesis of severe malaria during pregnancy, the long-term consequences of pre-eclampsia for mother and child, immune-metabolic trajectories of pregnancy and how maternal immune cells affect immunity and neurocognition in offspring. Further, we develop organoids relevant to understand feto-maternal immune cross talk as well as tools to improve data management and sharing.

Prediction of preterm birth - prevention of inequality among children

schwangere (1).jpg

Each year, approx. 15 million babies worldwide are born prematurely, before gestation week 37. These children have an increased risk to die during their first year of life and to develop health problems. These include a greater susceptibility for infections, allergies, asthma and also poorer neurocognitive performances. In adult life, being born too soon can also affect the ability to work, which further aggravates the inequalities resulting from prematurity.

 

Despite continuous progress made in the field of preventive medicine over the last decades, the options to predict preterm birth are still very poor. Therefore, it is the goal of our project to characterize biological signatures that are predictive for preterm birth at a time point during pregnancies when no risk can be foreseen. Such knowledge will then inform future prenatal care and allows to identify pregnancies at risk for preterm birth by clinical routine screening.

Our network comprises of partners located at the Medical Faculty of the Universität Hamburg, at the University of Groningen, NL as well as at Stanford University and University of California San Diego, USA, which allows us to address the research question in a translational approach, combined with -omics technology-derived data and machine learning-based predictive modeling.

ONGOING RESEARCH

The PRINCE Study (PRenatal IdeNtification of Children’s HEalth) is a prospective longitudinal pregnancy cohort study which commenced in 2011 at the University Medical Center Hamburg.
It is one of the most comprehensive cohorts of healthy pregnant women in Europe. The current number of mother-child pairs is 750. Pregnant PRINCE participants are seen three times during pregnancy, at the end of the first trimetser of pregnancy (gestation week 12-14), the second trimester (week 24) and the third trimester (week 34. At each study visit, ultrasound is performed and a maternal venous blood sample is taken. Pregnancy progression, health status and weight gain of the mother are documented, along with nutrition, stress perception, use of medication or infections. Pregnancy complications – if occuring - are recorded and immidiately treated. The health and early life environment of the babies born in the PRINCE study is documented using questionnaires, sent between the age of six month to four years. Queries include the use of childhood vaccination and the incidence of infections. At the age of five and ten years, the children participate in an on-site visit, where a physical examination is performed, blood is taken and lung function and neurocognitive performance are tested. 

 

The aim of the PRINCE Study is to understand how children ‘s health is determined before birth – or how childhood diseases may be programmed very early.
 

Add-on studies to the PRINCE Study, in which healthy pregnant women are included, have ben initiated. These include the PRINCE_Covid Study, in which pregnant women suffering from COVID-19 have been recruited. Additonally, women vaccinated during pregnancy, i.e. with the Corona vaccine, are enrolled in the PRINCE-Vaccine Study. Furthermore, the PRINCE-Breast Study has just started. Here, women diagnosed with breats cancer during pregnancy are included. 
 

The PRINCE Studies have been conceptionalized, initiated and are supervised by Anke Diemert, a certified OB/GYN specialist and Professor of Midwifery, and Petra Arck, Professor for Experimental Feto-Maternal Medicine. 

If you are pregnant, live in or near Hamburg and interested in participating the study, please visit our German PRINCE website

Sexual and Reproductive Health in Overweight and Obesity (SHROO)

BMBF.jpeg

The new BMBF-funded Interdisciplinary Junior Scientist Research Centre entitled “Sexual and Reproductive Health in Overweight and Obesity (SHROO)  promotes motivated Medical and Clinician Scientists to develop an independent research career and leadership in order to strengthen the field of sexual and reproductive health in overweight and obesity. We seek to recruit junior scientists who want to improve our understanding of the interaction between overweight and obesity on sexual and reproductive health throughout life, aiming to improve clinical care for affected individuals. 

A team of experts from translational and clinical fields of obstetrics, midwifery, immunology, glycobiology, metabolic surgery, endocrinology, prevention, sexual medicine, and health services research which will serve as mentors and supervisors for the selected junior scientists. An environment in which wet lab research, clinical research and public health-related research can be pursued.
