Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Most experts in the field consider Multiple Sclerosis as the main auto immune disease of the central nervous system. In spite of many works, the data in the literature concerning the antigens targeted by the CD8+ T-Cell response are still contradictory and insufficient.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

30 patients distributed in 3 groups of 10 patients with specific inclusion criteria will participate in this trial:

* 10 MS patients in early disease onset,
* 10 MS patients under Natalizumab treatment
* and control group of 10 patients with other neurological diseases.

The aim of this clinical trial is to detect the CD8+ myelin specific T-Cells in the blood of Multiple Sclerosis patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Multiple Sclerosis

Human Leukocyte Antigen (HLA)-A2 patients whose Multiple Sclerosis has just been diagnosed

Group Type EXPERIMENTAL

Blood samples

Intervention Type BIOLOGICAL

The blood will be sampled in order to be tested in Immunology, twice, the day they sign their agreement and six months after in case of positive myelin pentamer test (at inclusion and 6 months after the inclusion).

Control

HLA-A2 patients hospitalized in the neurology department who are not affected with a neuroimmunological disorder

Group Type OTHER

Blood samples

Intervention Type BIOLOGICAL

The blood will be sampled in order to be tested in Immunology, once, the day they sign their agreement (at the inclusion)

Multiple Sclerosis patients treated

HLA-A2 Multiple Sclerosis patients treated by Natalizumab therapy

Group Type EXPERIMENTAL

Blood samples

Intervention Type BIOLOGICAL

The blood will be sampled in order to be tested in Immunology, twice, the day they sign their agreement and six months after in case of positive myelin pentamer test (at inclusion and 6 months after the inclusion).
