We study how the molecular machinery involved in plasma membrane organization and remodeling translates into signaling pathways and cellular responses during homeostatic and pathological conditions.
The plasma membrane is the first interface mediating the interaction of cells with the external environment. Following an external stimulus, endocytosis is the primary process by which cells regulate the plasma membrane composition, allowing micronutrient uptake or the redistribution of cell surface receptors. The plasma membrane also represents the last proteolipid layer before secretion/exocytosis of cellular constituents involved in antiviral responses and inflammation. Consequently, endocytosis and exocytosis are often hijacked by viruses, toxins, and bacteria to access the host cell and perturb the host microenvironment.
In the team, we investigate the cellular components and pathways allowing signal transmission from virus/receptor binding and internalization, virus sensing, and innate immune response regulating antiviral and inflammatory molecules secretion/exocytosis leading to cell activation, maturation, and migration required for the establishment of host-specific antiviral immunity.
RESEARCH THEME: “Mechanisms of endocytosis”
Project leader: L. Picas
The research theme “mechanisms of endocytosis” is focused on deciphering how receptor-driven plasma membrane reorganization and endocytosis translate signals into cells and induce cellular responses to incoming viruses (e.g. CHIKV). We study the physical principles and molecular machinery driving clathrin-mediated endocytosis, the canonical pathway in all eukaryotic cells that support housekeeping functions, and clathrin-independent mechanisms, which provide an exciting opportunity as novel therapeutic approaches.
RESEARCH THEME: “DC antiviral immunity”
Project leader: F. Blanchet
The research theme “DC antiviral immunity” uses ex vivo-derived human primary immune cell types (Dendritic cells, macrophages) to decipher how endocytic processes are linked to downstream recognition of viruses (CHIKV, HIV-1, etc.) or stress molecules and subsequent innate antiviral immune responses. We also characterize the cellular components of the host innate immune response and define their function on viral replication and transmission of infection when confronted with host antiviral immunity and inflammation.
Identification of unconventional endocytic mechanisms involved in viral uptake
Although clathrin-mediated endocytosis is considered the canonical entry pathway of alphavirus into the host cell, increasing evidence points out that parallel mechanisms exist to infect cells. In the team, we combine cell biology and virology approaches to identify new clathrin-independent mechanisms that participate in the chikungunya virus (CHIKV) entry into host cells.

DC immune responses linked to the cellular autophagy pathway upon viral infections
Autophagy and receptor-mediated endocytosis are involved in HIV-1 entry into dendritic cells (DCs) thus leading to the formation of special intracellular structures coined “immunoamphisomes” which influence both innate and adaptive immune responses. Several receptors, including DC-SIGN, are seemingly involved in this process.
Our aim is therefore to better characterize the first steps of HIV-1 entry and the role of autophagy at this level. The impact of autophagy on innate and adaptive immune responses and the relationship between HIV-1 and autophagy are also currently analyzed in different DC subtypes. We are also trying to dissect the signaling pathways downstream of receptor-mediated endocytosis and the link with autophagy-related factors. Our ambition is to reinforce DC immune functions when virally challenged by modulating cellular autophagy components and endocytic pathways.
Collaboration: V. Haucke (Berlin), M. Lehmann (Berlin), Y. Guerardel (Lille).
Spatio-temporal organization of endocytosis, from molecules to cells
A general feature of all endocytic processes is that they require the inward bending of the plasma membrane to form a transport vesicle. This process is achieved thanks to protein machinery recruited at the plasma membrane, and that will help on the bending, elongation, and scission of vesicles.
At the molecular level, we use bottom-up synthetic systems to reconstitute endocytic processes. Using these systems, we can address the role of the lipid composition of membranes and investigate the structural organization and dynamics of endocytic proteins.
At the cellular level, we combine cell biology, and virology approaches with a toolbox of cutting-edge imaging techniques, from sub-diffraction microscopy to correlative light and atomic force microscopy.

Deciphering Antiviral Immune Responses in human DC subsets
Potent restriction mechanisms are present in DC subsets to counteract and respond to most viral infections. While several DC subtypes are not bona fide targets of HIV-1 replication and infection, many cellular mechanisms of viral restriction remain to be identified or better characterized. We are using state-of-the-art high-throughput transcriptomics and proteomics techniques in human primary DC subsets in order to reveal potential cellular antiviral mechanisms involved in cellular immune responses.
Among the DC subsets studied, we are particularly interested in deciphering Langerhans cells antiviral immune responses. As such we recently uncovered an unsuspected intracellular role for the alarmin S100A9 in the susceptibility to HIV-1 infection of LC. We are now trying to further characterize the mechanism of action of S100A9 on viral restriction while also trying to understand the functional immunobiological balance between intracellular and extracellular pools of alarmins upon viral infections.

Plasma membrane mechano-transduction, from molecules to cellular functions
The ability of proteins to sense and respond to changes in the plasma membrane topology is an important feature triggering the selective accumulation of endocytic proteins to nanometer-scale topologies, as in the case of BAR domain proteins, but also supporting cellular functions, in which cells respond to topological features of the extracellular matrix (e.g., topotaxis). In the team, we combine novel soft-lithography approaches with sub-diffraction microscopy to study the principles of plasma membrane mechano-transduction at the molecular level, using bottom-up synthetic systems, and at the cellular level, investigating the motility of DC cells.
