Phagocyte migration and differentiation

Isabelle Maridonneau-Parini

Group Leader

Macrophages infiltrate all body tissues which are heterogeneous in composition, stiffness and architecture. This process, critical for immune protection, also promotes inflammatory diseases and cancers, and its control has become a pharmacological challenge. In this attempt, we are investigating the molecular and cellular mechanisms involved in macrophage 3D migration.

We have shown that macrophages use two migration strategies, the amoeboid and mesenchymal modes, depending on the matrix porosity, and that, amongst leukocytes, only macrophages are capable of using the mesenchymal migration mode.

Macrophage infiltration into tumor cell spheroids and in vivo into mouse tumors involves mesenchymal migration.

In the tuberculosis context, macrophages with a bacilli-permissive phenotype exhibit an enhanced capacity for mesenchymal migration. 

Mesenchymal migration requires proteases to create paths in the matrix and podosomes, the unique adhesion structures formed by macrophages. We have identified three podosome effectors, Hck, Filamin A and WASp, as key regulators of mesenchymal migration. An ongoing comparative transcriptomic analysis of 3D-migrating macrophages will lead to the identification of additional candidate genes regulating mesenchymal migration.
As podosomes play a critical role in mesenchymal migration, we have also started investigating their mechanical properties, and have revealed that protrusive forces are generated at podosomes in order to sense the rigidity of the environment. We are currently developing new experimental approaches as well as automated image analysis tools dedicated to the characterization of podosome force, architecture and dynamics. HIV-1, the pathogen responsible for AIDS, uses macrophages as host cells. It manipulates their migration by affecting podosomes, further supporting our team’s strategy of identifying pharmacological targets to control macrophage migration in pathological situations.
