Tissue infiltration of phagocytes exacerbates several human pathologies including chronic inflammations or cancers. However, the mechanisms involved in macrophage migration through interstitial tissues are poorly understood. We investigated the role of Hck, a Src-family kinase involved in the organization of matrix adhesion and degradation structures called(More)
A key strategy in microbial pathogenesis is the subversion of the first line of cellular immune defences presented by professional phagocytes. Enteropathogenic and enterohaemorrhagic Escherichia coli (EPEC and EHEC respectively) remain extracellular while colonizing the gut mucosa by attaching and effacing mechanism. EPEC use the type three secretion system(More)
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(More)
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(More)
