Read our Multiple Sclerosis research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand why different people with multiple sclerosis have different patterns of disease — some with sudden attacks and others with steady progression. This study examines specific immune cells in your blood and spinal fluid to learn which cells are causing damage in different types of MS, so doctors can eventually develop better treatments.
Current MS treatments help many patients, but none can completely stop the disease from progressing. By studying the immune cells in people with MS, researchers hope to discover why some people respond differently to disease and which cells should be targeted by future medications.

You will not need any extra visits — the study uses blood and spinal fluid samples that are already being collected as part of your routine MS care at Bordeaux University Hospital. Researchers will examine your immune cells from these samples to understand how they differ between people with different types of MS. Your clinical progress and any treatments you receive will be tracked over time and linked to what the researchers find in your samples.
