Abstract
Tumor-associated macrophages (TAMs) are detrimental in most cancers. Controlling their recruitment is thus potentially therapeutic. We previously found that TAMs perform protease-dependent mesenchymal migration in cancer, while macrophages perform amoeboid migration in other tissues. Inhibition of mesenchymal migration correlates with decreased TAM infiltration and tumor growth, providing rationale for a new cancer immunotherapy specifically targeting TAM motility. To identify new effectors of mesenchymal migration, we produced ER-Hoxb8-immortalized hematopoietic progenitors (cells with estrogen receptor-regulated Hoxb8 expression), which show unlimited proliferative ability in the presence of estrogen. The functionality of macrophages differentiated from ER-Hoxb8 progenitors was compared to bone marrow-derived macrophages (BMDMs). They polarized into M1- and M2-orientated macrophages, generated reactive oxygen species (ROS), ingested particles, formed podosomes, degraded the extracellular matrix, adopted amoeboid and mesenchymal migration in 3D, and infiltrated tumor explants ex vivo using mesenchymal migration. We also used the CRISPR/Cas9 system to disrupt gene expression of a known effector of mesenchymal migration, WASP (also known as WAS), to provide a proof of concept. We observed impaired podosome formation and mesenchymal migration capacity, thus recapitulating the phenotype of BMDM isolated from Wasp-knockout mice. Thus, we validate the use of ER-Hoxb8-immortalized macrophages as a potent tool to investigate macrophage functionalities.

Abstract
Macrophages infiltrate and establish in developing organs from an early stage, often before these have become vascularized. Similarly, leukocytes, in general, can quickly migrate through tissues to any site of wounding. This unique capacity is rooted in their characteristic amoeboid motility, the genetic basis of which is poorly understood. Trim33 (also known as Tif1-γ), a nuclear protein that associates with specific DNA-binding transcription factors to modulate gene expression, has been found to be mainly involved in hematopoiesis and gene regulation mediated by TGF-β. Here, we have discovered that in Trim33-deficient zebrafish embryos, primitive macrophages are unable to colonize the central nervous system to become microglia. Moreover, both macrophages and neutrophils of Trim33-deficient embryos display a reduced basal mobility within interstitial tissues, and a profound lack of a response to inflammatory recruitment signals, including local bacterial infections. Correlatively, Trim33-deficient mouse bone marrow-derived macrophages display a strongly reduced three-dimensional amoeboid mobility in fibrous collagen gels. The transcriptional regulator Trim33 is thus revealed as being essential for the navigation of macrophages and neutrophils towards developmental or inflammatory cues within vertebrate tissues.

Abstract
The human immunodeficiency virus (HIV-1) disseminates in the body and is found in several organs and tissues. Although HIV-1 mainly targets both CD4+ T lymphocytes and macrophages, it has contrasting effects between these cell populations. HIV-1 infection namely reduces the viability of CD4+ T cells, whereas infected macrophages are long-lived. In addition, the migration of T cells is reduced by the infection, whereas HIV-1 differentially modulates the migration modes of macrophages. In 2-dimensions (2D) assays, infected macrophages are less motile compared to the control counterparts. In 3D environments, macrophages use two migration modes that are dependent on the matrix architecture: amoeboid and mesenchymal migration. HIV-1-infected macrophages exhibit a reduced amoeboid migration but an enhanced mesenchymal migration, via the viral protein Nef. Indeed, the mesenchymal migration involves podosomes, and Nef stabilizes these cell structures through the activation of the tyrosine kinase Hck, which in turn phosphorylates the Wiskott–Aldrich syndrome protein (WASP). WASP is a key player in actin remodeling and cell migration. The reprogramed motility of infected macrophages observed in vitro correlates in vivo with enhanced macrophage infiltration in experimental tumors in Nef-transgenic mice compared to control mice. In conclusion, HIV infection of host target cells modifies their migration capacity; we infer that HIV-1 enhances virus spreading in confined environments by reducing T cells migration, and facilitates virus dissemination into different organs and tissues of the human body by enhancing macrophage mesenchymal migration.

Abstract
Infiltration of macrophages into tissue can promote tumour development. Depending on the extracellular matrix architecture, macrophages can adopt two migration modes: amoeboid migration--common to all leukocytes, and mesenchymal migration--restricted to macrophages and certain tumour cells. Here, we investigate the initiating mechanisms involved in macrophage mesenchymal migration. We show that a single macrophage is able to use both migration modes. Macrophage mesenchymal migration is correlated with decreased activity of Rho/Rho-associated protein kinase (ROCK) and is potentiated when ROCK is inhibited, suggesting that amoeboid inhibition participates in mechanisms that initiate mesenchymal migration. We identify the cyclin-dependent kinase (CDK) inhibitor p27(kip1) (also known as CDKN1B) as a new effector of macrophage 3D-migration. By using p27(kip1) mutant mice and small interfering RNA targeting p27(kip1), we show that p27(kip1) promotes mesenchymal migration and hinders amoeboid migration upstream of the Rho/ROCK pathway, a process associated with a relocation of the protein from the nucleus to the cytoplasm. Finally, we observe that cytoplasmic p27(kip1) is required for in vivo infiltration of macrophages within induced tumours in mice. This study provides the first evidence that silencing of amoeboid migration through inhibition of the Rho/ROCK pathway by p27(kip1) participates in the onset of macrophage mesenchymal migration.

Abstract
Leukocytes migrate through most tissues in the body, a process which takes place in 3D environments. We have previously shown that macrophages use the amoeboid migration mode in porous matrices such as fibrillar collagen I and the mesenchymal mode involving podosomes and matrix proteolysis in dense matrices such as Matrigel. Whether such a plasticity may apply to other leukocytes and to all subsets of macrophages is unknown. Here, we therefore provide a comparative analysis of the in vitro 3D migration modes adopted by primary human leukocytes. Blood-derived monocytes, neutrophils and T lymphocytes were found to use the amoeboid mode in a porous fibrillar collagen I matrix but were unable to infiltrate dense Matrigel and to form podosomes. M2-polarized macrophages and elicited peritoneal macrophages formed podosome rosettes, degraded the ECM and infiltrated both matrices. In contrast, M1 macrophages were motionless in 2D and 3D environments, whilst resident macrophages, devoid of podosomes, were only able to use the amoeboid mode. Thus, we conclude that whereas all leukocytes use the amoeboid mode to migrate through porous matrices, it is only certain macrophages that can adopt the mesenchymal mode that permits migration through dense matrices. Interestingly, the acquisition of mesenchymal migration capacity by macrophages correlates with the presence of podosomes and with their capacity to organize those as rosettes, which appears to be modulated by their differentiation and polarization states. As a perspective, specific control of the mesenchymal migration would be a potential target for therapeutic approaches aiming at decreasing macrophage tissue infiltration.

Abstract
Tumor-associated macrophages are known to amplify the malignant potential of tumors by secreting a variety of cytokines and proteases involved in tumor cell invasion and metastasis, but how these macrophages infiltrate tumors and whether the macrophage migration process facilitates tumor cell invasion remain poorly documented. To address these questions, we used cell spheroids of breast carcinoma SUM159PT cells as an in vitro model of solid tumors. We found that macrophages used both the mesenchymal mode requiring matrix metalloproteinases (MMPs) and the amoeboid migration mode to infiltrate tumor cell spheroids. Whereas individual SUM159PT cells invaded Matrigel using an MMP-dependent mesenchymal mode, when they were grown as spheroids, tumor cells were unable to invade the Matrigel surrounding spheroids. When spheroids were infiltrated or in contact with macrophages, tumor cell invasiveness was restored. It was dependent on the capacity of macrophages to remodel the matrix and migrate in an MMP-independent mesenchymal mode. This effect of macrophages was much reduced when spheroids were infiltrated by Matrigel migration-defective Hck(-/-) macrophages. In the presence of macrophages, SUM159PT migrated into Matrigel in the proximity of macrophages and switched from an MMP-dependent mesenchymal migration to an amoeboid mode resistant to protease inhibitors.Thus, in addition to the well-described paracrine loop between macrophages and tumor cells, macrophages can also contribute to the invasiveness of tumor cells by remodeling the extracellular matrix and by opening the way to exit the tumor and colonize the surrounding tissues in an MMP-dispensable manner.

Abstract
Macrophage tissue infiltration is a critical step in the immune response against microorganisms and is also associated with disease progression in chronic inflammation and cancer. Macrophages are constitutively equipped with specialized structures called podosomes dedicated to extracellular matrix (ECM) degradation. We recently reported that these structures play a critical role in trans-matrix mesenchymal migration mode, a protease-dependent mechanism. Podosome molecular components and their ECM-degrading activity have been extensively studied in two dimensions (2D), but yet very little is known about their fate in three-dimensional (3D) environments. Therefore, localization of podosome markers and proteolytic activity were carefully examined in human macrophages performing mesenchymal migration. Using our gelled collagen I 3D matrix model to obligate human macrophages to perform mesenchymal migration, classical podosome markers including talin, paxillin, vinculin, gelsolin, cortactin were found to accumulate at the tip of F-actin-rich cell protrusions together with β1 integrin and CD44 but not β2 integrin. Macrophage proteolytic activity was observed at podosome-like protrusion sites using confocal fluorescence microscopy and electron microscopy. The formation of migration tunnels by macrophages inside the matrix was accomplished by degradation, engulfment and mechanic compaction of the matrix. In addition, videomicroscopy revealed that 3D F-actin-rich protrusions of migrating macrophages were as dynamic as their 2D counterparts. Overall, the specifications of 3D podosomes resembled those of 2D podosome rosettes rather than those of individual podosomes. This observation was further supported by the aspect of 3D podosomes in fibroblasts expressing Hck, a master regulator of podosome rosettes in macrophages. In conclusion, human macrophage podosomes go 3D and take the shape of spherical podosome rosettes when the cells perform mesenchymal migration. This work sets the scene for future studies of molecular and cellular processes regulating macrophage trans-migration.

Abstract
Tissue infiltration of macrophages, although critical for innate immunity, is also involved in pathologies, such as chronic inflammation and cancer. In vivo, macrophages migrate mostly in a constrained three-dimensional (3D) environment. However, in vitro studies, mainly focused on two dimensions, do not provide meaningful clues about the mechanisms involved in 3D macrophage migration. In contrast, tumor cell 3D migration is well documented. It comprises a protease-independent and Rho kinase (ROCK)-dependent amoeboid migration mode and a protease-dependent and ROCK-independent mesenchymal migration mode. In this study, we examined the influence of extracellular matrix (composition, architecture, and stiffness) on 3D migration of human macrophages derived from blood monocytes (MDMs). We show that: 1) MDMs use either the amoeboid migration mode in fibrillar collagen I or the mesenchymal migration mode in Matrigel and gelled collagen I, whereas HT1080 tumor cells only perform mesenchymal migration; 2) when MDMs use the mesenchymal migratory mode, they form 3D collagenolytic structures at the tips of cell protrusions that share several markers with podosomes as described in two dimensions; 3) in contrast to tumor cells, matrix metalloproteinase inhibitors do not impair protease-dependent macrophage 3D migration, suggesting the involvement of other proteolytic systems; and 4) MDMs infiltrating matrices of similar composition but with variable stiffness adapt their migration mode primarily to the matrix architecture. In conclusion, although it is admitted that leukocytes 3D migration is restricted to the amoeboid mode, we show that human macrophages also perform the mesenchymal mode but in a distinct manner than tumor cells, and they naturally adapt their migration mode to the environmental constraints.

Abstract
Hck is a phagocyte specific proto-oncogene of the Src family expressed as two isoforms, p59Hck and p61Hck. It plays a critical role in Bcr/Abl-chronic myeloid leukaemia and is able to transform fibroblasts in vitro. However, the tumourigenic activity of Hck and the respective oncogenic functions of Hck isoforms have not been examined. Tet-Off fibroblasts expressing constitutively active mutants of p59Hck and p61Hck together or individually were used. In contrast to cells expressing p59Hck(ca) or p61Hck(ca) alone, cells expressing both isoforms were transformed in vitro and induced tumour formation in 90% of nude mice within 2 weeks. This is the first demonstration of (i) the tumourigenic activity of Hck in mice, (ii) the cooperative action of the two Hck isoforms in vitro and in vivo. To our knowledge, this is the first example of a transforming activity 'split' in two requisite isoforms.

Abstract
In chronic myeloid leukemia (CML), the transforming activity of Bcr/Abl involves constitutive activation of the phagocyte specific Src-family tyrosine kinase Hck, which in turn directly activates the signal transducer and activator of transcription 5 (STAT5). The effect of Hck on STAT5 was first explored independently of Bcr/Abl by expressing the constitutively active Hck mutant (Hck(ca)) in MEF3T3-TetOff fibroblasts. As previously reported, Hck(ca)-expressing cells form podosomes which are actin-rich structures involved in trans-tissular cell migration and found in the few cell types able to cross anatomic boundaries. We demonstrated that in these cells, the tyrosine-phosphorylated form of STAT5 (PY-STAT5) increased and preferentially localized on podosomes together with Hck, instead of translocating to the nucleus as observed with conventional stimuli such as IFNgamma. To examine whether similar results were obtained in the presence of Bcr/Abl, the CML cell line K562 was used. We observed that (i) podosomal structures are present in these cells in contrast to Bcr/Abl-negative leukemic cells, (ii) podosome formation was inhibited by Bcr/Abl- and Src-kinase inhibitors, and (iii) PY-STAT5 mainly colocalized with Hck on these structures. The presence of podosomes was not sufficient to trap STAT5 since in normal macrophages which spontaneously form podosomes and express regulated Hck, PY-STAT5 is in the nucleus. In conclusion, this is the first report showing that PY-STAT5 associates to podosomes in a process dependent on constitutive activation of Hck. We propose that STAT5, previously classified as a transcription factor, could play another role outside the nucleus, elicited by the Bcr/Abl-Hck transforming pathway.

Abstract
Podosomes are adhesion structures with an extracellular matrix-degrading capacity mostly found in monocyte-derived cells. We have previously shown that the protein tyrosine kinase Hck, a member of the Src family, triggers the de novo formation of podosome rosettes in a lysosome-dependent manner when expressed in its constitutively active form. Hck is specifically expressed in myeloid cells. In human monocyte-derived macrophages (MDMs) it is present at podosomes. Here we addressed whether its activation by lipopolysaccharide and interferon-gamma has an effect on podosome organization in MDMs. Several structures were observed evolving from individual podosomes to clusters, aggregates and rosettes. In chronic myeloid leukemia cells, Hck is constitutively activated by the fusion protein Bcr-Abl and podosome-like structures were present. Finally, in monocyte-derived osteoclasts, Hck was found to accumulate at podosome belts. In conclusion, in monocyte-derived cells, it is likely that Hck could play a role in podosome re-arrangements.

Abstract
Haematopoietic cell kinase (Hck) is a protein tyrosine kinase of the Src family specifically expressed in phagocytes as two isoforms, p59Hck and p61Hck, present at the plasma membrane and lysosomes, respectively. We report that ectopic expression of a constitutively active mutant of p61Hck (p61Hck(ca)) triggered the de novo formation of actin-rich rings at the ventral face of the cells that we characterized as bona fide podosome rosettes, structures involved in cell migration. Their formation required the adaptor domains and the kinase activity of p61Hck, the integrity of microfilament and microtubule networks and concerted action of Cdc42, Rac and Rho. Podosome rosette formation was either abolished when p61Hck(ca) was readdressed from lysosomes to the cytosol or triggered when p59Hck(ca) was relocalized to lysosomes. Lysosomal markers were present at podosome rosettes. By stimulating exocytosis of p61Hck(ca) lysosomes with a calcium ionophore, the formation of podosome rosettes was enhanced. Interestingly, we confirm that, in human macrophages, Hck and lysosomal markers were present at podosomes which were spatially reorganized as clusters, a foregoing step to form rosettes, upon expression of p61Hck(ca). We propose that lysosomes, under the control of p61Hck, are involved in the biogenesis of podosomes, a key phenomenon in the migration of phagocytes.

Abstract
The macrophage mannose receptor (MR) appears to play an important role in the binding and phagocytosis of several human pathogens, but its phagocytic property and signaling pathways have been poorly defined. The general strategy to explore such topics is to express the protein of interest in nonphagocytic cells, but in the case of MR, there are few reports using the full-length MR cDNA. When we searched to clone de novo the human MR (hMR) cDNA, problems were encountered, and full-length hMR cDNA was only obtained after devising a complex cloning strategy. Chinese hamster ovary cells, which have a fully functional phagocytic machinery when expressing professional phagocytic receptors, were stably transfected, and cell clones expressing hMR at quantitatively comparable levels than human macrophages or J774E cells were obtained. They exhibited a functional hMR-mediated endocytic capacity of a soluble ligand but failed to ingest classical particulate ligands of MR such as zymosan, Mycobacterium kansasii, or trimannoside bovine serum albumin-coated latex beads. Transient expression of hMR in two human cell lines did not provide a phagocytic capacity either. In conclusion, we show that MR is not a professional phagocytic receptor, as it does not possess the ability to promote particle ingestion in nonphagocytic cells on its own. We propose that MR is a binding receptor, which requires a partner to trigger phagocytosis in some specialized cells such as macrophages. Our new expression vector could represent a useful tool to study the receptor and its partnership further.

Abstract
Two types of opsonic phagocytosis have been defined depending on the receptor engaged: FcgammaRs mediate type I phagocytosis of IgG-coated particles; complement receptor 3 (CR3) mediates type II phagocytosis of complement-coated particles. In addition to opsonic phagocytosis, CR3 also mediates nonopsonic phagocytosis of zymosan (Z) and Mycobacterium kansasii through engagement of distinct sites. Using Chinese hamster ovary cells stably expressing human CR3, we studied CR3-mediated ingestion of nonopsonized particles, Z or M. kansasii, compared with opsonized zymosan (OZ). We show that 1) while OZ sinks into cells, Z is engulfed by pseudopodia as visualized by electron microscopy; 2) in contrast to OZ, nonopsonic phagocytosis of Z and M. kansasii depends on Rac and Cdc42 but not on Rho activity; and 3) CR3-mediated phagocytosis of Z depends on the kinase activity of the Src family tyrosine kinase Hck, while OZ internalization does not. Therefore, CR3 mediates type I phagocytosis under nonopsonic conditions and type II under opsonic conditions. This is the first evidence that a single receptor can mediate both types of phagocytosis depending on the ligand used.
