Membrane compartmentalization by tetraspanins and cell differentiation
Scientific Team Leader: : Dr. Eric Rubinstein (DR Inserm)
Tetraspanins play a crucial role in many physiological functions such as sperm-egg fusion, muscle regeneration, the visual and renal functions , as well as immunity. They also play an important role in major pathologies including cancer, malaria, hepatitis C and AIDS. They play a role in cell compartmentalization , through the regulation of the trafficking of various proteins, and also in membrane compartmentalization. The goal of the “tetraspanin” team is to determine how tetraspanins function at the molecular level, and to unravel the physiopathological importance of some of them.
Cells communicate with their environment through membrane receptors which recognize molecules and particles in the external milieu and transmit an intracellular signal that can lead to gene activation or alternatively to activation of other membrane receptors and cytoplasmic targets. Whereas the membrane has long been considered a fluid mosaic, most recent evidence show that it is not homogeneous, and that several factors oppose to the free diffusion of molecule in the membrane. One of these factors is the interaction with membrane structures of particular composition such as microdomains. Membrane compartmentalization inside these microdomains contributes to ligand binding and/or signalling.
We have been interested in membrane compartmentalization through the study of a family of membrane proteins called tetraspanins. Tetraspanins are four transmembrane domains proteins with discrete structural features. There are 33 tetraspanins in mammals, and so far all cell types studied express several of these molecules, often at a high level. Tetraspanins have been implicated in various biological processes such as cell adhesion, migration, cell fusion, co-stimulation, signal transduction, and differentiation. The array of observed effects suggest that tetraspanins play a role in basal functions of the cell.

The importance of these molecules in various physiological and pathological conditions has been unravelled during the recent years. There are now several genetic diseases caused by mutations in particular tetraspanins. Also several tetraspanins are used for the infection by several pathogens. In particular, HIV recruits several tetraspanins at the site of budding. The tetraspanin CD81 drew particular attention because it plays an essential role in the infection by two important human pathogens. It is on the one hand an obligatory receptor for the hepatitis C virus, a major cause of hepatocellular carcinoma. Additionally, we have shown in collaboration with Olivier Silvie and Dominique Mazier (Inserm U1135) that in plays a major role in the entry of the malaria parasite into hepatocytes (Silvie et al., Nat. Med., 2003, 9: 93).
The idea that tetraspanins play a role in membrane compartmentalization, that could be defined as non-randomness (of localization, of interactions) in the membrane, comes from the demonstration by several groups, including ours, that tetraspanins organize a network of interactions that we referred to as the tetraspanin web (Rubinstein et al., Eur. J. Immunol., 1996, 26: 2657) (Rubinstein et al., Eur. J. Immunol., 1996, 26: 2657), and is also called as tetraspanin-enriched microdomains. We have shown that these structures are highly organized, with a particular tetraspanin targeting specific non-tetraspanin partner molecules (to which they associate directly) to these domains. We have demonstrated that they are built with the help of lipids, cholesterol participating to the maintenance of these structures, as well as lipid-modifications (palmitoylation) of tetraspanins (Charrin et al., FEBS Lett., 2002, 516: 139; Charrin et al., Eur. J. Immunol., 2003, 33: 2479). We have also published the first proteomic characterization of these structures: They contain 4 major groups of proteins, including integrins, proteins with Ig domains, ectoenzymes and heterotrimeric G proteins (Andre et al., Proteomics., 2006, 6: 1437; Le Naour et al., Mol. Cell Proteomics., 2006, 5: 845).
Fig. 2 Les tétraspanines constituent un puzzle moléculaire à la surface cellulaire:
Biochemical studies have demonstrated specific interactions of certain tetraspanins (here in green) with a few numbers of associated molecules (their molecular partners). For example, CD9 and CD81 have two common partners designed as CD9P-1 or EWI-2. Discrete microdomains arise as tetraspanins associate with each others. Thus each tetraspanin is likely to induce the association of its molecular partners with the microdomains.
Our current projects concern three axis of research based on the studies we have published in the recent years.
The role of the tetraspanins in intercellular fusion process.
We have in the past demonstrated, through the creation of knock-out mice, that the tetraspanin CD9 present on the oocyte surface plays an essential role in sperm-egg fusion, in cooperation with CD81 (Le Naour et al., Science, 2000, 287: 319; Rubinstein et al., Dev. Biol., 2006, 290: 351). We are still analyzing the role of CD9 in this process, in collaboration with Christine Gourier and Eric Perez, at ENS Paris, et the team of Jean-Philippe Wolf at Cochin institute.
We have also recently shown that these two tetraspanins, CD9 and CD81, are negative regulators of the fusion of muscle cells (Charrin et al., 2013, Nat Commun.;4:1674). Their presence prevents the fusion of multinucleated myotubes in vitro, and of regenerating myofibers in vivo. This negative regulation of fusion plays a role in the ad integrum restoration of muscle architecture in the course of regeneration. We have also demonstrated that CD9P-1, a direct partner of both CD9 and CD81 contributed to this negative regulation of fusion. We are studying the underlying mechanisms.
In conclusion, our study unveils a mechanism preventing inappropriate fusion of myotubes that plays an important role in the restitution of normal muscle architecture during muscle regeneration.
Tspan8 in colon cancer.
The tetraspanin Tspan8 has a restricted pattern of expression, and is particularly expressed on digestive epitheliums. We have shown on the one hand that a decrease expression of Tspan8 is a good prognosis parameter in colon cancer. On the other hand, Tspan8 coordinates cell motility by integrating various signals issued from the membrane (integrins, E-cadherin, EGFR) (Greco et al., 2010, Cancer Res 70 :7674). In addition, we have shown that the anti-Tspan8 mAb TS29.2 produced in the laboratory significantly inhibited the growth of colon cancer cell lines grafted in the mouse (Ailane et al., 2014, Front Physiol., 5:364).
Ainsi ce travail démontre que la tétraspanine Tspan8 joue un rôle important dans la progression du cancer du côlon et suggère qu’il pourrait constituer une bonne cible thérapeutique dans cette pathologie.
Regulation of the metalloprotease ADAM10 by tetraspanins and its implication for Notch signalling.
We have shown that a subgroup of 6 tetraspanins (Tspan5, 17, 14, 33, 5, 10) that have 8 cysteines in the large extracellular domain (and therefore are referred to as TspanC8) were all direct partners of ADAM10 and regulated its exit from the endoplasmic reticulum (Dornier, et al., 2012, J Cell Biol,199:481).
ADAM10 plays a key role in Notch signaling. Indeed, Notch can be described as a membrane-tethered transcriptional co-activator . The binding of Notch to its membrane-tethered ligands results in a double cleavage by ADAM10 and the γ-secretase complex that allow the translocation of Notch intracellular domains into the nucleus. We have shown that Tspan5 and Tspan15 are positive regulators of Notch signaling, probably by regulating ADAM10 ability to cleave Notch.
En collaboration avec l'équipe de François Schweisguth (Institut Pasteur), nous avons montré que les TspanC8 de drosophile s'associent également à ADAM10 (aussi appelée Kuz chez la drosophile) dont elles modulent la distribution cellulaire, régulent l'expression de cibles de Notch, et jouent un rôle important dans plusieurs aspects du développement dépendant de Notch.
Most mammalian tetraspanins have no orthologs in invertebrates, suggesting an independent evolution of these molecules in the different phylums. In contrast, TspanC8 have clear orthologs in C. elegans and D. melanogaster (up to 40 % identity). We have shown, in collaboration with the group of François Schweisguth (Institut Pasteur), that the three Drosophila TspanC8 modulate Notch signalling in vivo, acting specifically on the receptor, and that this was associated with a modification of Kuz localization.
In conclusion, this study has identified a set of evolutionary conserved tetraspanins that control ADAM10 surface expression level thereby regulating Notch signaling.
