Andrea Edlow, MD, MsC, is a member of the Obstetrics and Gynecology Faculty at Harvard Medical School and a Maternal-Fetal Medicine specialist at Massachusetts General Hospital.

The laboratory of Andrea Edlow, MD, MSc, at Massachusetts General Hospital investigates the effects of maternal immune activation on fetal brain development and offspring behavior, and how these effects are modified by placental immune activation and fetal sex.  Our work focuses on pre-clinical models (rodent) of maternal diet-induced obesity, and translational work with maternal COVID-19 infection in pregnancy.

Our lab was one of the first to use amniotic fluid supernatant and umbilical cord blood to investigate real-time fetal brain development in obese human pregnancy.

Gene expression profiling of these two biofluids identified abnormal gene expression signatures in fetuses of obese women, highlighting dysregulated brain development and increased inflammation.

Using a validated mouse model of maternal diet-induced obesity, we have demonstrated significant sex differences in the impact of maternal obesity on embryonic brain development, catecholamine neurotransmitter signaling, and offspring neurobehavior.

Maternal diet during pregnancy and lactation also significantly influences in utero brain development and offspring behavior.

Ultimately, we anticipate this work will provide targets for a lifestyle/behavioral intervention, and possibly for prenatal therapies that could be given orally to obese pregnant women, to reverse or ameliorate deleterious structural and functional changes.

During the COVID-19 pandemic, our lab pivoted to expand our focus to maternal SARS-CoV-2 infection in pregnancy. Partnering with a multi-disciplinary team, we have worked across the Mass General Brigham system to establish one of the largest COVID-19 Pregnancy Biorepositories in the country. Through these samples generously provided by enrolled participants, we have generated key insights into maternal immune response, vertical transmission and placental antibody transfer.

Postdoctoral Position Available

We are recruiting a postdoctoral fellow to work in the Edlow Laboratory within the Vincent Center for Reproductive Biology on NIH-funded projects focused on fetal brain-placental immune activation in the setting of maternal immune activation. Maternal immune-activating conditions of interest include obesity, diabetes, and viral infections. Experience in immunology, placental biology, neuroscience and/or systems/computational biology is ideal, but not required. Our research broadly focuses on the programming effects of maternal immune activation on fetal and offspring brain development and behavior, and the placenta-brain connection. We utilize pre-clinical models and human samples to explore mechanisms underlying neurodevelopmental and metabolic morbidity in offspring exposed to immune activation in utero. We also focus on the impact of offspring sex on these outcomes. Our approach is multidisciplinary and highly collaborative. Our laboratory is affiliated with Harvard Medical School and Massachusetts General Hospital, as well as with the Innovation Center on Sex Differences in Medicine at Mass General.

Job Description

The Edlow Laboratory for basic and translational research is sited in the Vincent Center for Reproductive Biology (VCRB) on the main campus of Massachusetts General Hospital. Ongoing studies focus on the neurodevelopmental and metabolic programming effects of maternal obesity, maternal high-fat diet, and maternal viral infection (e.g. with SARS-CoV-2) during pregnancy and lactation. We work both with mouse models of maternal obesity as well as with human participant samples (placenta, maternal blood, cord blood, breastmilk and others). We evaluate the impact of maternal immune activation on placental and fetal immune activation. In the murine model, we assess fetal, juvenile, and adult offspring brain development using molecular and immunohistochemical techniques, as well as neurobehavioral testing. Areas of focus include: (1) the effects of maternal immune activation on offspring cognition and mood outcomes (anxiety, depression), particularly as they relate to neuroinflammation and brain-immune interactions; (2) Developing novel cellular models of fetal brain development using proxy cell types; (3) Developmental programming of offspring feeding behaviors (reward-based feeding governed by the mesolimbic dopamine circuit) and offspring metabolic parameters (including insulin resistance, body fat composition, and dysregulation of leptin, ghrelin, and other peripheral and central hormonal signaling); (4) Utilizing novel targeted therapeutics to improve offspring neurodevelopmental outcomes; and (5) Elucidating the role of fetal and offspring sex in mediating the effects of maternal diet-induced obesity on neurodevelopment. 

Experience in the following is either required or preferred (as indicated):
- Extensive experience with molecular techniques including RNA/DNA/protein assays (required)
- Experience with cell isolations from tissue and blood (animal or human) and with techniques such as RNA-sequencing and flow cytometry/FACS (preferred)
- Experience with mouse models and handling, including rodent surgery (preferred)
- Experience either performing or working with bioinformatics analyses of sequencing data (preferred, but can provide training for interested applicants)
- Experience with brain retrieval, tissue preservation for immunohistochemical analyses, brain or placental sectioning and tissue staining, and neurobehavioral testing (preferred)
- Skill in collection, organization, management, and analysis of complex data sets (required)
- Skill in experimental design, protocol development, and troubleshooting (required)
- Skill in data analysis using statistical analytical tools is required. Experience with Graphpad Prism and/or SPSS/STATA/SAS is preferred. 
- Experience preparing manuscripts for publication, experience with review and summarization of relevant literature for manuscript background and grant preparation (required). Preparation of study findings and presentation at professional meetings will also be strongly encouraged.

There are many opportunities for education and growth in our multidisciplinary, collaborative research program that brings together a diverse group of obstetrician-gynecologists, neuroscientists, immunologists, endocrinologists, animal neuroimagers at the world-class Athinoula Martinos Center for Brain Imaging, and translational and clinical researchers at the Innovation Center on Sex Differences in Medicine.
