Detection of cell surface nucleolin for identification of activated cells in cancer
It is now well demonstrated that cancer that’s diagnosed at an early stage is more likely to be treated successfully. This is particular true for pancreatic ductal adenocarcinoma (PDAC) that remains asymptomatic. Consequently, there is an urgent need to identify biomarkers useable in the diagnosis.
Human Monoclonal Antibodies: a New Therapeutic Strategy against BK virus Infection and Associated Diseases
BK virus (BKV) infection has a major negative impact on the transplant recipient community. It is estimated that up to 30% of the 60,000 kidney transplants performed annually worldwide are potentially compromised by BKV-associated nephropathy (BKVAN) or BKV replication. Furthermore, prolonged BKV re
Ectopic kainate receptors in temporal lobe epilepsy: a new therapeutic target
Mesial temporal lobe epilepsy (TLE), one of the most common forms of epilepsy in adults, is frequently intractable. We have recently explored the pathophysiological implications of kainate receptors (KARs) in chronic seizures in a mouse model of TLE. We have demonstrated that aberrantly expressed sy
Mitochondrial calcium homeostasis in the control of arrhythmia associated with metabolic cardiomyopathy
The control and the regulation of the mitochondrial Ca2+ homeostasis is a primary sensor of the cardiac metabolic disorder. We here propose that (i) MCU expression, structure and function integrates cardiac metabolic flexibility, (ii) the MCU composition dynamically affect mitochondrial Ca2+ homeost
Analytical characterization of hybrid nanoparticles for clinical trial
During last decade, scientific community has shown strong interest for hybrid nanoparticles and their biomedical applications as highlighted by the growing number publications on this field of research. Despite this academic research, only a small number of nanoparticles succeeds to go in clinic. It
PGI2 pathway to enhance wound healing in diabetic foot ulcers
Structural and functional abnormalities of the cutaneous microcirculation in diabetic patients with ulcer support its critical role in the pathophysiology of DFUs. However, the detailed mechanisms underlying such dysfunction remain largely unexplored. The prostacyclin (PGI2) is an important regulato
New Concepts in Chronic Inflammatory Neuropathies: from biomarkers to individualize therapy
During the past years, our group have shown that accurate examination of medical imaging and electrophysiology can help better individualize subgroups of patients and define specific therapeutic approaches. In addition, we recently identified autoantibody targets in patients with chronic inflammator
Induction of neonatal Fc receptor-mediated tolerance to autologous therapeutic proteins
Several pathological situations result from the inability of the organism to mount immune tolerance towards exogenously administered molecules, as observed in alloimmune responses to protein therapeutics. This is particularly true of hemophilia A, a rare X-linked recessive life-threatening, cripplin
Identification of key regulators for a gene network associated to epilepsy
The main objective of the EpiReg project is the identification of genetic drivers for epilepsy by integrating systems genetics approaches and experimental functional in vivo expertise of the INSERM U1141 collaborators. The epilepsy-associated gene regulatory network M30 was previously identified (re
Combo vaccines for emerging infectious diseases
Several arboviruses, such as dengue fever, Zika fever, chikungunya, or West Nile virus circulate simultaneously in the same geographical areas. It would be interesting to have multivalent vaccines against several of these infections which can be fatal. This new vector has been constructed. It makes
Role of mitophagy and innate immune system in the febrile decompensations of inherited rhabdomyolysis: Therapeutic perspectives
Rhabdomyolysis (RM) results from a impairment in ATP metabolism and a deregulation of ion channels, leading to a rapid increase of cytoplasmic ionized calcium concentration and the destruction of muscle cells. Although rare, the prognosis of RM related to Inherited Metabolic Diseases (IMD) is poor,
Osteoinductive implants for the regeneration of critical-size bone defects
To date, the repair of critical sized bone defects remains a clinical unmet need. Autograft, the current gold standard, presents several drawbacks justifying safer strategies. “Orthobiologics” products that combine synthetic grafts, mostly collagen sponges and ceramics, and bioactive molecules such
Translational and multimodal brain imaging investigation of the neural correlate of arousal and awareness
In the last decades, advances in Intensive Care Unit management have led to decreased mortality. However, significant morbidity remains as patients survive after a lesional coma with uncertain quality of awakening and high risk of functional disability. The possible dissociated consciousness recover
Characterization of placental biomarkers of fetal brain defects after in utero alcohol exposure
Alcohol consumption during pregnancy constitutes the main cause of acquired handicap and most children presenting fetal alcohol spectrum disorders (FASD) are not diagnosed at birth. However, these infants are not devoid of neurodevelopmental troubles that will be detected at school-age. Neonatal dia
Narcolepsy type 1 physiopathology
Narcolepsy type 1 (NT1) is a disabling orphan disorder characterized by excessive daytime sleepiness and cataplexy, often associated with hypnagogic hallucinations, sleep paralysis, nighttime sleep disruption and weight gain. NT1 is a chronic disorder, and in the large majority of patients it is a s
PET-MR imaging of an animal model of multiple sclerosis: evaluation of new radiotracers for myelin
Multiple sclerosis is the prototype autoimmune disorder of the central nervous system. Effective therapies to reverse neuronal damage and restore function are a major unmet need. New drugs that promote the formation of myelin may be effective in reducing long-term disability. An associated imaging m
Idiopathic Chronic Thrombocytopenia of Undetermined Significance (ICTUS): pathogenesis and biomarker
Acquired chronic isolated thrombocytopenias are frequent disorders. Most of them are related to an auto-antibody mediated destruction leading to the diagnosis of Immune Thrombocytopenic Purpura (ITP). We previously demonstrated that some of these ITP are not due to an immune disorder, but rather are
Development of tools to eliminate onchocerciasis in Loa loa-coendemic areas
Onchocerciasis is a parasitic vector-borne disease caused by the filaria Onchocerca volvulus (Ov) prevalent mainly in Africa. Due to its ocular and cutaneous complications, individual and public health burden are high where infection prevalence exceeds 40%. Since 1989, populations in such “meso-hype
Therapeutic innovation from extinction of lupus in haemodialysis
Systemic lupus is a rare autoimmune disease leading to end stage renal disease (ESRD) in 25% of cases. It highlights the need for treatment innovation for systemic lupus and lupus nephritis. Despite important efforts made by the medical community, research groups, and pharmaceutical companies, rando
Therapy by modulation of Dynamin 2 expression
Centronuclear myopathies (CNM) are rare congenital myopathies characterized by abnormal centralization of nuclei in muscle fibers. Three main forms of CNM are distinguished: The X-linked recessive CNM (also called X-linked myotubular myopathy, XLMTM) due to mutations in myotubularin (MTM1), the auto
BOTHROPS SNAKE ENVENOMATION ENGAGES ABERRANT HOST DEFENSE RESPONSE THROUGH RECOGNITION OF CELLULAR AND MITOCHONDRIAL DAMAGE-ASSOCIATED MOLECULAR PATTERNS (DAMPS) TO INDUCE MULTIPLE ORGAN AND DEATH
Background: In 2017, World Health Organization reinstated snakebite envenoming to its priority list of neglected tropical diseases. In France, concern is related to the fashion of maintaining exotic snakes as pets, whereas Bothrops sp. are responsible for life-threatening envenomations in French guy
Hepatic sphingolipids in NAFLD: from liver biosynthesis to metabolic consequences
Non-alcoholic fatty liver disease (NAFLD) encompasses a wide range of pathologies from steatosis to non-alcoholic steatohepatitis (NASH), fibrosis and finally cirrhosis. It is a very common pathology during type 2 diabetes (T2D), resulting in excess mortality. NAFLD also promotes the development of
