What is the Zerial lab?
Our vision is to develop a systems understanding of the molecular mechanisms underlying cell and tissue organization. Over the years, we have been studying the molecular mechanisms of endocytosis, unravelling the key role played by Rab GTPases and their effectors. This work has led us to demonstrate that Rab5 is a master regulator of early endosome biogenesis. We have recently conducted a systems biology analysis by genome-wide RNAi screening in HeLa cells and in C. elegans, using quantitative multi-parametric image analysis (QMPIA). This led us to gain insights into the design principles of the endosomal system. We are now ready to apply this methodology to the multi-scale analysis of tissue organization and function.

Alice Cezanne, one of our predocs, won a poster award at the EMBO meeting on “Endocytic trafficking and signalling in health and disease” (11-15 September in Serock, Poland). She presented her work on the mechanisms governing lateral organisation of the Rab5 machinery on the Early Endosome. [Read more]
