Dr. Mohamad Navab is a Professor in the Departments of Medicine, Cardiology at the David Geffen School of Medicine at UCLA, with 32 years of research experience in the study of atherosclerosis, lipids and artery wall metabolism. His work has been continuously supported by the National Institutes of Health (NIH). He is CoProject Leader on an NIH PPG/grant that is going into its 31st year. He has published 195 peer-reviewed articles (average H index 90), including 100 chapters and reviews, co-edited two books, and organized three interdisciplinary symposia in the area of lipids and artery wall metabolism. His current research focus is on the role of the role of small intestine, systemic inflammation and cardiovascular function. He has been involved in studies of gut microbiota in dyslipidemia and the effect of HDL mimetic peptides on it.

Dr. Victoria Niklas is a Professor in the Department of Pediatrics at the David Geffen School of Medicine at UCLA and the Director of the Neonatal Intensive Care Unit and Newborn Services at Olive View-UCLA Medical Center. Dr. Niklas earned her medical degree from Harvard Medical School and a master’s degree in Biochemistry and Molecular Biology from Harvard University. She completed her residency in pediatrics at Children’s Hospital Los Angeles and a fellowship in perinatal and neonatal medicine at UCLA.

Dr. Niklas has over 25 years of experience as a clinician investigator and neonatologist integrating basic and translational science in diseases afflicting the newborn. Her career has focused on understanding the immune system in the susceptibility of the newborn to infection and inflammation in the body’s largest mucosal surface, the intestine. She is a recognized expert in mouse models of intestinal immune T cell development and the pathogenesis of intestinal inflammation, in diseases such as necrotizing enterocolitis, a life-threatening intestinal disease of primarily premature infants. More recently, she was the site PI for a phase I/II RCT of enteral human recombinant lactoferrin evaluating its role in reducing hospital-acquired infections (HAI) in very low birth weight infants. Lactoferrin was safe and reduced HAI in premature infants. Also, the normally pathogenic flora was reduced in the feces of lactoferrin treated infants when compared to controls, suggesting one possible mechanism whereby lactoferrin reduced HAI in these infants.

Dr. Niklas wishes to extend these studies by exploring metagenomic signatures of maternal disease (such as obesity) in the taxonomic composition of the gut microbiota acquired by the newborn at birth. Well-described microbial signatures of obesity in adults may result in disease-associated microbial signatures in the newborn intestine. Hence, maternal flora may have a long-lasting impact on the infant’s later risk of diseases, such as obesity, in later life. The reduction in childhood obesity among breastfed infants suggests that components in breast milk (lactoferrin, milk’s microbiome, or milk oligosaccharides) may lower this risk. Possibly by influencing heritability or stability of an obesity-associated intestinal microbiome. Advanced genomic tools and sequencing will be used to explore the composition and diversity of this microbiome between mother and baby. It is, however, envisioned, that a “Mother Baby Cohort” will serve as a springboard for extended “life studies” enabling interdisciplinary, interventional and observational studies of health and disease. These endeavors will advance knowledge and ultimately improve care practices in the management in the perinatal interface with a far-reaching impact on our understanding of health and the origins of disease throughout life.
