Exosomes in cancer theranostic: Diamonds in the rough
2017
IF 3.306; International audience; During the last 10 years, exosomes, which are small vesicles of 50-200 nm diameter of endosomal origin, have aroused a great interest in the scientific and clinical community for their roles in intercellular communication in almost all physiological and pathological processes. Most cells can potentially release these nanovesicles that share with the parent cell a similar lipid bilayer with transmembrane proteins and a panel of enclosed soluble proteins such as heat shock proteins and genetic material, thus acting as potential nanoshuttles of biomarkers. Exosomes surface proteins allow their targeting and capture by recipient cells, while the exosomes' conte…
Evidence-Based Clinical Use of Nanoscale Extracellular Vesicles in Nanomedicine
2016
collaboration au projet H2020 European Cooperation in Science and Technology (COST) program European Network on Microvesicles and Exosomes in Health and Disease (ME-HAD); International audience; Recent research has demonstrated that all body fluids assessed contain substantial amounts of vesicles that range in size from 30 to 1000 nm and that are surrounded by phospholipid membranes containing different membrane microdomains such as lipid rafts and caveolae. The most prominent representatives of these so-called extracellular vesicles (EVs) are nanosized exosomes (70-150 nm), which are derivatives of the endosomal system, and microvesicles (100-1000 nm), which are produced by outward budding…

Functionalization of Metal and Carbon Nanoparticles with Potential in Cancer Theranostics
2021
Cancer theranostics is a new concept of medical approach that attempts to combine in a unique nanoplatform diagnosis, monitoring and therapy so as to provide eradication of a solid tumor in a non-invasive fashion. There are many available solutions to tackle cancer using theranostic agents such as photothermal therapy (PTT) and photodynamic therapy (PDT) under the guidance of imaging techniques (e.g., magnetic resonance—MRI, photoacoustic—PA or computed tomography—CT imaging). Additionally, there are several potential theranostic nanoplatforms able to combine diagnosis and therapy at once, such as gold nanoparticles (GNPs), graphene oxide (GO), superparamagnetic iron oxide nanoparticles (SP…
Development of trackable metal-based drugs: new generation of therapeutic agents
2016
International audience; In medicinal chemistry, the aim is not only to conceive ever more efficient molecules, but also to understand their mechanism of action. In very recent years, a new promising strategy was developed to tackle this issue: the conception of trackable therapeutic agents. Metal-based drugs are ideal to exploit this expanding area of research.

Alpha emitting nuclides in nuclear medicine theranostics.
2021
Theranostic applications with radio-isotopes currently are rapidly progressing and expand nuclear medicine application in clinical routine. Alpha emitting isotopes, in particular, have long been hypothesized to achieve relevant advances for the treatment of malignancies. Here, an overview of their properties and the knowledge of radiobiology is reviewed in view of clinical translation. Clinical evidence of radiopharmaceuticals based on alpha emitters is summarized with a focus on recent developments for treatment of metastasized castration resistant prostate cancer.Theranostische Anwendungen mit Radioisotopen machen derzeit rasche Fortschritte und erweitern den Einsatz der Nuklearmedizin in…
Naphthalimide imidazolium-based supramolecular hydrogels as bioimaging and theranostic soft materials
2020
1,8-Naphthalimide-based imidazolium salts differing for the alkyl chain length and the nature of the anion were synthesized and characterized to obtain fluorescent probes for bioimaging applications. First, their self-assembly behavior and gelling ability were investigated in water and water/dimethyl sulfoxide binary mixtures. Only salts having longer alkyl chains were able to give supramolecular hydrogels, whose properties were investigated by using a combined approach of fluorescence, resonance light scattering, and rheology measurements. Morphological information was obtained by scanning electron microscopy. In addition, conductive properties of organic salts in solution and gel state we…
Extracellular Vesicle-Mediated Cell–Cell Communication in the Nervous System: Focus on Neurological Diseases
2019
Extracellular vesicles (EVs), including exosomes, are membranous particles released by cells into the extracellular space. They are involved in cell differentiation, tissue homeostasis, and organ remodelling in virtually all tissues, including the central nervous system (CNS). They are secreted by a range of cell types and via blood reaching other cells whose functioning they can modify because they transport and deliver active molecules, such as proteins of various types and functions, lipids, DNA, and miRNAs. Since they are relatively easy to isolate, exosomes can be characterized, and their composition elucidated and manipulated by bioengineering techniques. Consequently, exosomes appear…
Copper radiopharmaceuticals for theranostic applications
2018
The growing advancement in nuclear medicine challenges researchers from several different fields to integrate imaging and therapeutic modalities in a theranostic radiopharmaceutical, which can be defined as a molecular entity with readily replaceable radioisotope to provide easy switch between diagnostic and therapeutic applications for efficient and patient-friendly treatment of diseases. For such a reason, the diagnostic and therapeutic potential of all five medical radionuclides of copper have thoroughly been investigated as they boost the hope for development of successful radiotheranostics. To facilitate the mutual understanding between all different specialists working on this multidi…
