Dr Karen Forbes

Profile

I am an Associate Professor of Molecular Endocrinology and Reproduction, leading a research programme that investigates how the maternal metabolic environment shapes placental function, fetal growth, and long-term cardiometabolic health of the offspring. My work focuses particularly on pregnancies complicated by diabetes, with an emphasis on the role of extracellular vesicles and microRNA-mediated signalling in maternal–placental–fetal communication.
My research spans mechanistic studies in human and experimental models through to translational work aimed at identifying early biomarkers and therapeutic targets to improve pregnancy and long-term health outcomes. I have established an international research profile in this field and have published extensively on placental biology, extracellular vesicle signalling, and developmental programming of disease.

Research interests

Current Research Projects

Maternal extracellular vesicles as mediators of inter-organ communication in metabolic pregnancy disease
This programme investigates extracellular vesicle (EV)–mediated crosstalk between maternal tissues, the placenta, and the fetus, and how disruption of this signalling contributes to adverse pregnancy outcomes in diabetes and obesity.
Key collaborators: Prof Eleanor Scott (Leeds); Prof Susan Ozanne (University of Cambridge); Dr Beth Holder (Imperial College London); Prof Jürgen Schneider (Leeds); Prof Lee Roberts (Leeds); Prof Eylem Levelt (Baker Heart & Diabetes Institute, Melbourne)

SWEETTALK: Maternal–placental communication in metabolic pregnancy disorders
A joint UK–Germany programme examining immune–metabolic and EV-mediated signalling pathways linking maternal metabolism and placental function in diabetes and obesity.
Collaborator: Prof Sandra Blois (Universität Hamburg)

Extracellular vesicle cargo as predictors of adverse pregnancy outcomes
Identification and validation of maternal EV-based biomarkers for fetal overgrowth, placental dysfunction, and long-term cardiometabolic risk.
Collaborators: Prof Eleanor Scott (Leeds); Prof Alex Heazell (University of Manchester)

Placental vascular development and dysfunction in healthy and complicated pregnancies
Mechanistic analysis of placental vascular structure and signalling in healthy and diabetic pregnancies, integrating histology, advanced imaging, molecular profiling, and novel human placental vascular models.
Collaborators: Prof Eleanor Scott (Leeds); Dr Jayne Charnock (Edge Hill University); Dr Kristina Haase (EMBL Barcelona); Dr Lynn McKeown (Leeds); Dr Paul Meakin (Leeds)

Therapeutic modulation of placental microRNAs to improve fetal growth
Testing whether targeted manipulation of placental microRNA pathways can rescue placental dysfunction and abnormal fetal growth in compromised pregnancies.
Collaborator: Dr Lynda Harris (University of Nebraska Medical Center)

Student education

I offer BSc, MSc, MD and PhD research projects spanning reproductive biology and pregnancy, with a particular emphasis on endocrinology, diabetes, nutrition, and the developmental origins of health and disease (DOHaD). Projects integrate cell and molecular biology approaches to investigate cell signalling pathways, non-coding RNAs, and extracellular vesicle–mediated communication in health and disease. Please contact me to enquire about current projects on offer.
