Learn About Biofilms; New Episode of "That's Pediatrics"

UPMC Children’s Hospital of Pittsburgh has launched a new medical podcast series for physicians, scientists and other health care professionals featuring the hospital’s leading researchers and clinicians. Episodes of “That’s Pediatrics” will include compelling interviews with scientists at UPMC Children’s Hospital who are performing innovative basic, translational, and clinical research. 

Dr. DePas' lab is focused on developing a clear picture of the biogeography of infection sites, determining how the spatial structure impacts bacterial activity and interactions with host cells, and recapitulating important aspects of the infection environment in vitro in order to gain an in-depth understanding of cellular processes that are relevant to pathogenesis. To achieve these goals, they utilize MiPACT-HCR, a tissue-clearing and cellular visualization technique that allows for 3D imaging of fixed tissue samples, along with in vitro techniques to characterize the formation and dispersal of bacterial biofilms in conditions that mimic the in vivo environment. Dr. DePas' lab is chiefly interested in nontuberculous mycobacteria (NTM), emerging pathogens that are particularly problematic for patients with CF. By applying their described methodology, they are working to determine the context in which NTM form biofilms during infection and how biofilm formation contributes to disease severity.
