TWEAK, a New Biomarker for Predicting Inflammatory Relapses in Multiple Sclerosis (TWEAK)

18. september 2026 opdateret af: Assistance Publique Hopitaux De Marseille

TNF-relateret svag inducer af apoptose (TWEAK), en ny biomarkør, der forudsiger inflammatorisk fremstød i multipel sklerose

A significant variation in the serum concentration of the circulating cytokine TWEAK is associated with the onset of an inflammatory attack of MS. Study the concentration variations of the serum soluble form of cytokine TWEAK during the first year of MS and to analyze their correlation with the occurrence of an inflammatory disease outbreak.

Detaljeret beskrivelse

Multiple sclerosis (MS) is the most common chronic autoimmune demyelinating and neurodegenerative disease of the central nervous system (CNS) of disabling neurological diseases in young adults in France. Patients with MS can present a wide range of symptoms spread over time and space such as motor, sensory, visual or vesico-sphincter deficits. One of the current challenges in treating patients with symptoms suggestive of MS is to assess the risk of an inflammatory flare in order to avoid or limit the installation of an irreversible neurological handicap. At present, the inflammatory activity of the disease is evaluable only by cerebral imaging (MRI). However, these examinations can not be carried out as often as necessary because of their accessibility, cost, duration and the potential deleterious effects of gadolinium accumulation. This is why a blood biomarker able to report early on the inflammatory activity of the disease would be of great help during the monitoring and treatment of patients. TWEAK (TNF-related weak inducer of apoptosis or TNFSF12) is a pro-inflammatory cytokine member of the TNF family. This cytokine is overexpressed in tissues with chronic inflammatory diseases such as MS. It is produced by monocytes / macrophages and microglial cells and can exist in soluble or membrane form the investigators of the clinical department were the first to describe the pro-inflammatory role of TWEAK in MS. Indeed, the investigators have demonstrated in an animal model of MS that the inhibition of TWEAK makes it possible to reduce the severity of the disease. Their recent work (manuscript submitted for publication) has also shown results from a series of 28 patients with MS suggesting that the serum TWEAK assay may be an early marker of thrust occurrence. The investigators propose to study the concentration variations of the serum soluble form of cytokine TWEAK during the first year of MS and to analyze their correlation with the occurrence of an inflammatory disease outbreak. The investigators will perform a prospective study in which 50 patients with MS in the isolated clinical syndrome stage will be included over a 12-month period. Mental Cerebral MRIs will be performed for each patient at baseline (T0), month 6, and month 12. Serum dosages of TWEAK will be performed each month for each patient for one year. Patients will also be treated with soluble TNF, the leader in the TNF family of ligands, anti-TWEAK antibodies (which may interfere with the activity and dosage of TWEAK) as well as C-reactive Protein C ( search for intercurrent infectious episode). These dosages will be correlated with the clinical evolution (appearance or not of an inflammatory flare) as well as the data of the imagery (number of lesions raised or not by the gadolinium).

Andet: serum concentration changes in cytokine TWEAK

We will perform a prospective study in which 50 patients with multiple sclerosis in the isolated clinical syndrome stage will be included over a 12-month period. Mental Cerebral MRIs will be performed for each patient at baseline (T0), month 6, and month 12. Serum dosages of TWEAK will be performed each month for each patient for one year. Patients will also be treated with soluble TNF, the leader in the TNF family of ligands, anti-TWEAK antibodies (which may interfere with the activity and dosage of TWEAK) as well as C-reactive Protein C ( search for intercurrent infectious episode). These dosages will be correlated with the clinical evolution (appearance or not of an inflammatory flare) as well as the data of the imagery (number of lesions raised or not by the gadolinium).

Blood samples (20 ml of blood on dry tube) by venipuncture at the bend of the elbow will be made at T0, then monthly for a period of 1 year . The sera will be isolated by centrifugation and then frozen at -80 degrees Assays of the soluble form of TWEAK and TNF will be performed by ELISA blot technique developed by the team.
