Sergio Grinstein completed his Ph.D. in 1976 at the Centro de Investigacion, in Mexico City. He then spent two years as a post-doctoral fellow at the Hospital For Sick Children in Toronto, followed by a year in the Department of Biochemistry at the Federal Institute of Technology in Zurich. He is currently working at the Hospital For Sick Children in Toronto, where he was Head of the Program in Cell Biology from 1987-2007 and has been Professor of Biochemistry at the University of Toronto since 1988.
Dr. Grinstein is interested in membrane biology, ion transport and the innate immune response.
In the News
Sergio’s group studies two different topics. One topic deals with the regulation of ion transport and pH of intracellular compartments and the researchers have devised a means of measuring the pH and ionic composition of individual organelles within intact live cells. The second area of interest relates to the interaction between the innate immune system and invading microorganisms. The Hospital for Sick Children has an impressive Imaging Facility which provides a full range of imaging solutions for life sciences research.

Membrane Biology, Ion Transport, and the Innate Immune Response
Dr. Grinstein’s group is interested in several aspects of membrane biology and signal transduction. Part of his group studies ion transport mechanisms and regulation, with particular interest in the regulation of the intracellular pH. Another sub-group studies the molecular basis of the innate immune response, mostly in macrophages. The receptors, signals and effectors that mediate phagocytosis are topics of interest, as is the interaction of pathogens with host cells.
