Tetraspanin-enriched membrane microdomains in extracellular vesicles and cell adhesion and migration

Research summary:

Our group is focused on the characterization of tetraspanin-enriched microdomains (TEMs), specialized membrane platforms involved in cell-cell adhesion and migration processes. These membrane platforms are connected to different cytoskeletal components and signalling pathways. We have demonstrated a functional connection of tetraspanin CD81 with the dNTP hydrolase SAMHD1, that results in regulation of nucleotide metabolism downstream TEMs. This axis was proven to be relevant during HIV infectious cycle, and was protected through a patent that describes CD81 as a new target to fight against HIV infection.

In addition, tetraspanin proteins are among the most abundant proteins on extracellular vesicles (EVs). EVs represent a novel mechanism of intercellular communication as vehicles for bioactive proteins, lipids, and RNAs. In our group, we are exploiting the tools against tetraspanin molecules to develop new isolation, detection and quantification devices. We are also interested in deciphering the role of tetraspanins in EV biogenesis and uptake by the target cell. Finally, we are developing synthetic exosome mimetics by the use of tetraspanin-based tools.


Figure 1. Tetraspanin-enriched microdomains and their functions. It has been demonstrated that TEM-induced clustering or segregation of adhesion receptors and signalling molecules plays a functional role in phenomena related to migration and invasion, intercellular adhesion, membrane fusion events and intracellular trafficking. These phenomena are implicated in several biological processes. From Yáñez-Mó et al., Trends Cell Biol. 2009 Sep;19(9):434-46.


Figure 2. Tetraspanins in extracelular vesicle formation and function. Tetraspanins have the capacity to interact with several receptor and signaling molecules at the membrane, organizing specialized tetraspanin-enriched microdomains (TEMs) that may play a role in (A) EV biogenesis, (B) the selection of exosome cargo (proteins and miRNAs), (C) the binding and uptake of exosomes by target cells, or (D) the ability of exosomes to present antigen in the context of an immune response.
