Learn more about Dr. Deckelbaum

The major focus of Dr. Deckelbaum's laboratory is to determine regulatory mechanisms for cell-lipid particle interaction, cell cholesterol and triglyceride metabolism, and lipid-related gene expression. Current projects are defining the effects of lipid particle properties on their metabolism in the whole animal and with cells via receptor mediated and receptor independent pathways. Dr. Deckelbaum's laboratory has demonstrated that substantial amounts of lipoproteins and lipid emulsions can enter cells by receptor independent pathways. Integrated with these studies are studies on how different lipids, especially free fatty acids and various sphingolipids modulate sterol regulatory element binding protein (SREBP) mediated gene expression, focusing on genes affecting cell and whole body triglycerides and cholesterol homeostasis. Major areas of interest include: a) the role of triglyceride fatty acyl composition on modulating interaction of model lipid triglyceride-rich particles with apoprotein E and subsequent effects on cell and tissue metabolism in vitro, and in vivo, in mouse models. Dr. Deckelbaum's group is demonstrating that triglyceride-rich particles enriched in long chain omega-3 triglycerides do not enter tissues via classic receptor-dependent pathways but rather via other mechanisms which might relate to binding to non-receptor domains on the cell surface, such as phagocytosis or pinocytosis, and b) the actions of free fatty acids as potent regulators of a number of critical steps in cell lipid metabolism, via inhibition of expression mediated by sterol regulatory elements (SRE) in the promoter regions of lipid metabolism genes. Dr. Deckelbaum also coordinates programs related to the effects of varying nutrient intakes on expression of cardiovascular risk factors in children of different genetic backgrounds in both national and international studies. Overall, an important objective of Dr. Deckelbaum's program is to develop investigators who can translate basic nutritional questions into basic lipid and cellular biology.

Learn more about Dr. Lamousé-Smith

Dr. Lamousé-Smith is Assistant Professor of Pediatrics in the Pediatric Gastroenterology, Hepatology, and Nutrition and a member of the Columbia Center for Translational Immunology. Her background and training in cellular immunology and pediatric gastroenterology has led to a specific interest in understanding the role that the gastrointestinal flora has to play on health and disease in children. More specifically, her research is focused on two major questions: What is the impact of antibiotic use during early infancy on the acquisition and stability of the gastrointestinal flora? How does an intestinal flora altered by antibiotic use during infancy impact immune system development and function? In the lab she studies how infant and juvenile mice that are treated with antibiotics at specific ages are able to fight infection or respond to immunization. Complementing these antibiotic treatment models, she has also used germ free mice (mice born and maintained without a gastrointestinal flora) to further shed light on mechanisms by which the gastrointestinal tract flora influences immune function. Dr. Lamousé-Smith also has a specific clinical interest in the use of probiotics to manage gastrointestinal disorders in children. Both of the experimental models that she is studying in the lab provide a platform to experimentally test the potential role of probiotic species in promoting, supporting, and potentially correcting immune dysfunction. Eventually, the lab discoveries may help to inform the design and implementation of studies in human infants and children to learn how we can safely complement the use of probiotics during antibiotic treatment to prevent changes to the intestinal flora that could have consequences for normal immune function.

Learn more about Dr. Shen

Dr. Wei Shen is the Director of Image Analysis Lab and the Associate Director of the Body Composition Unit at the New York Obesity Nutrition Research Center. She has 12 years experience in body composition research, especially in MRI and MRS. Dr. Shen proposed the imaging adipose tissue classification (2003) and developed protocols for bone marrow (2007), intraperitoneal, extraperitoneal (2003, 2010), perimuscular and intramuscular adipose tissue (2003). Using statistical approach, Dr. Shen validated 3-D tissue volume models (2003) and identified the best single slice location (2004, 2008) and slice gap for MRI tissue quantification in adults and children (2010).Her NIH funded projects involve investigating visceral fat and health risks in children; and marrow fat with bone loss using MRI.
