Jacomine Krijnse Locker is a group-leader and heads the Ultrapole (platform of ultrastructural microscopy) at the Institut Pasteur in Paris. She obtained her PhD in Utrecht, the Netherlands, in 1994 on cellular aspects of coronaviruses.
LabEx IBEID – Integrative Biology of Emerging Infectious Diseases
Presentation Le but du projet Biologie Intégrative des Maladies Infectieuses Emergentes (IBEID), coordonné par les professeurs Philippe Sansonetti et Pascale Cossart, est de développer une structure pour anticiper et lutter contre les maladies […]
Embeding methods for salivary glands of mosquitos.
With the group of Anna-Bella Failloux we established a method to embed salivary glands of mosquitos infected with Chikungunya virus to study its replicative cycle in situ (Vega-Rua et al., 2016; viruses 7: pp. […]
FIB-SEM to study anterograde/retrograde transport in the flagellum of trypanosomes.
With the group of Philippe Bastin we have a long-standing collaboration to study the structure of protein complexes (or “trains”) that are moved by anterograde and retrograde transport in the flagellum of trypanosomes. Towards […]
Correlative approaches to study phagosomal membrane rupture.
The group of Jost Enninga studies the escape of intracellular bacteria from phagosomes using advanced imaging techniques. The aim is to study the process of phagosomal membrane rupture that mediates bacterial release into the […]
TNTs characterization by CryoEM
The group of Chiara Zurzolo studies the function, structure and formation of tunneling nano tubes (TNTs) that connect neuronal cells (Delage et al., 2016; Sci Rep 6: 39632). We provide EM support to characterize […]
The research group of the UBI studies membrane assembly of viruses, focusing predominantly on large DNA viruses. Using tools collected over the years, we use virus-infected cells to develop advanced EM-embedding and imaging methods that can be applied by the users of our platform. We put a particular emphasis on the development on two aspects in EM. The development of high-resolution cryo-EM methods to determine the structure of viral membrane-associated proteins in vitro and in situ. We also wish to broaden our portfolio of correlated- light and electron microscopy methods. For both we develop workflows that involve sample preparation, semi-automated imaging and image processing. We particularly welcome the input of autonomous users that can complement our efforts along their biological questions.
