Phagocyte architecture and dynamics

Christel Vérollet and Renaud Poincloux

Group Leaders

Our team combines cutting-edge techniques in optical and electron imaging, material science, cell mechanics and intra-vital imaging to elucidate how phagocytes, in particular macrophages and osteoclasts, interact with the extracellular matrix, to decipher the mechanisms of macrophage 3D migration and investigate how HIV-1 manipulates phagocyte cell-to-cell spread.

Macrophages are innate immune cells that maintain tissue homeostasis and immune surveillance in all tissues, but are also involved in disease progression (such as chronic inflammatory diseases and cancer). A therapeutic strategy is thus to limit tissue infiltration of pathogenic macrophages.

 

Using intravital microscopy, our team revealed that macrophages use the mesenchymal mode of migration to infiltrate dense tumors and that inhibitors of matrix metalloproteases both decreased the number of tumor-associated macrophages and tumor growth (Gui et al. 2018 Cancer Immunol. Res.). Podosomes are cell adhesion structures involved in the degradation of the extracellular matrix and the mesenchymal migration of macrophages. They are composed of a submicron core of actin filaments surrounded by a ring of integrin-based adhesion complexes.

Thanks to a method that we called protrusion force microscopy, we demonstrated that podosomes generate protrusive forces that are proportional to the stiffness of the extracellular matrix (Labernadie et al. 2014 Nat. Commun.; Proag et al. 2015 ACS Nano), and involve a balance of forces between core protrusion and a traction at the adhesion ring (Bouissou et al. 2017 ACS Nano). We also developed a device combining microchannels and pillars and reported that forces are redirected from inwards to outwards with increased cell confinement (Desvignes et al. 2018 Nano Letters).

 

We showed that the HIV-1 protein Nef modulates the migration of macrophages both in vitro and in vivo, and favors virus dissemination by enhancing the mesenchymal migration and by modulating podosome structure and function (Vérollet et al. 2015 Blood). In addition, we observed that osteoclasts are productively infected by HIV-1. The virus strongly alters podosome organization in osteoclasts, leading to enhanced bone resorption activity (Raynaud-Messina et al. 2018 PNAS USA). These observations likely explains macrophage accumulation in several tissues of HIV-1 infected patients and why they suffer from osteolysis. Macrophages are also the main host cells for Mycobacterium tuberculosis (Mtb). In the context of tuberculosis, we reported that macrophage mesenchymal migration is enhanced, and associated with an accumulation of Mtb-permissive macrophages in lungs (Lastrucci et al. 2015 Cell Research). More recently, we showed that, in tuberculosis microenvironment, the formation of tunneling nanotubes (TNT) by macrophages is increased. When these macrophages are subsequently infected by HIV-1 the virus spread between cells using TNT and the lectin Siglec-1/CD169. These mechanisms could explain how tuberculosis enhances HIV-1 pathogenesis in co-infected patients (Souriant et al., 2019 Cell Rep; Dupont et al., 2020 eLife).

Our article (Souriant S et al., 2019) published in @CellReports was highlighted in Editor's Choice in @sciencemagazine (April 26th, issue #6438). Great boost for the paper and the health issue we are addressing: co-infection with tuberculosis and AIDS !
