« Matrix metalloproteinase 11, a key player in adipocyte-cancer cell crosstalk »

 

It is well admitted that tumor microenvironment is crucial for cancer progression. In this context, matrix metalloproteinase 11 (MMP-11) represents a paracrine factor of bad prognosis in almost all human invasive cracinomas. Our studies bring evidence that MMP-11 negatively controls adipogenesis by limiting pre-adipocyte differentiation and/or reversing mature adipocyte differentiation, and that this function is aberrantly restored following adipocyte-cancer cell cross-talk during invasive processes. Collectively, these data strongly support the concept that adipocytes play an important role during tumor progression, and highlight the essential function of MMP-11 in this process. They are of particular interest since obesity is a worldwide health problem and epidemiological studies identify obesity as a poor prognosis factor for several cancers.

« Mechanisms and consequences of NFAT signaling pathway activation in innate immune cells in LPS-induced inflammatory conditions »

 

Innate immunity is the most ancient form of response to pathogens and it relies on evolutionary conserved signaling pathways, i.e. those involving the NF-kB pathway. Nevertheless, increasing evidence suggests that factors that have appeared more recently in evolution, such as the Nuclear Factor of Activated T cell transcription factor family (NFATc), also contribute to innate immune response regulation in vertebrates. We have observed that exposure to inflammatory stimuli, such as LPS, induces the activation of NFATc factors in innate immune cells, including conventional dendritic cells (DCs), with a mechanism TLR4-independent involving instead CD14. In turn, NFAT contributes to the regulation of IL-2 production, antigen transport to the lymph nodes via the lymph and DC life cycle. These three NFAT-controlled phenomena and the consequences of their activation will be discussed.
