The John J. Cebra Lectureship
“Dynamics of Endocytosis”
Tomas Kirchhausen, Harvard Medical School
July 13, 2012, Lillie Auditorium, 9:00 AM


KirchhausenTom Kirchhausen, PhD, a cell biologist and investigator in the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children’s Hospital Boston, studies “membrane trafficking,” a way by which cells move hormones, growth factors and viruses in and out of the cell. He is well known for the movies he produces in collaboration with animators, illustrating how cells work at the molecular level. His laboratory was one of the first to capture the entry of a virus into cells using real-time imaging.  He received his undergraduate degree in Biology from the Universidad Peruana Cayetano Heredia, earned his Ph.D. in Biophysics from the Instituto Venezolano de Investigaciones Cientificas, and did most of his post-doctoral training at Harvard.



About the John Cebra Lectureship

Professor John J. Cebra was trained as an immunochemist and protein chemist during the mid-1950s through the 1960s at The Rockefeller University, St. Mary’s Hospital, London, and the Weizmann Institute, Israel. In 1961, he established his own lab in the department of microbiology, University of Florida. During the 1960s he became interested in secretory IgA, and his group established its prevalence as a product of gut plasmablasts and its valid quaternary structure. In the 1970s he and others developed many novel principles concerning the IgA system and its Ab product.

Until his death in 2005, Professor Cebra was a professor of biology at the University of Pennsylvania where his group sought to understand the cellular and molecular mechanisms that led to the development of specific humoral and cellular mucosal immune responses, and the influence of commensal bacteria on mucosal immunity. Professor Cebra directed the MBL Physiology course from 1972 to 1976. He and his wife Ethel traveled abroad extensively to engage students of experimental biology in joint research projects. These visits stimulated continuing collaborative scientific interactions between the Cebra lab and various host laboratories worldwide. Professor Cebra considered his major accomplishment to be assisting in the training of 32 graduate students and many postdoctoral fellows.
