The Sherman laboratory at SickKids focuses on gastrointestinal disorders including necrotizing enterocolitis and colic in infants and irritable bowel syndrome and chronic inflammatory bowel diseases in older children and adults. Using complementary in vitro, ex vivo, and in vivo models of disease we investigate mechanisms by which non-traditional therapies such as probiotics (beneficial bacteria that, when ingested in sufficient amounts, provide health benefits to the host), prebiotics (non-digestible food ingredients that promote the growth of beneficial gut bacteria), and dietary micronutrients (vitamin D, vitamin B12, and omega-3 fatty acids) affect microbial homeostasis, mucosal inflammation, and influence the onset and progression of disease.
