Abstract:
Multiple sclerosis (MS) is a chronic inflammatory, demyelinating disease of the central nervous system, which starts in the majority of patients with a relapsing/remitting MS (RRMS) course , which after several years of disease duration converts into a progressive disease. Since anti-inflammatory therapies and immune modulation exert a beneficial effect at the relapsing/remitting stage of the disease, but not in the progressive stage, the question was raised whether inflammation drives tissue damage in progressive MS at all. We show here that also in progressive MS, inflammation is the driving force for brain injury and that the discrepancy between inflammation-driven tissue injury and response to immunomodulatory therapies can be explained by different pathomechanisms acting in RRMS and progressive MS.
Insights
Inflammation drives brain injury in progressive multiple sclerosis (MS), similar to the relapsing-remitting form. Different underlying mechanisms explain why therapies effective in early MS do not work in later stages.
Area of Science:
- Neuroimmunology
- Neurology
- Pathology
Background:
- Multiple sclerosis (MS) is a chronic central nervous system disease characterized by inflammation and demyelination.
- It typically begins with a relapsing-remitting MS (RRMS) course, later progressing to a more severe, irreversible stage.
- Current therapies are effective in RRMS but not in progressive MS, raising questions about inflammation's role in later stages.
Purpose of the Study:
- To investigate whether inflammation drives tissue damage in progressive multiple sclerosis (MS).
- To explore the reasons behind the differential response to immunomodulatory therapies between RRMS and progressive MS.
Main Methods:
- The study analyzed pathomechanisms of inflammation-driven tissue injury in both relapsing-remitting MS and progressive MS.
- Comparative analysis of inflammatory processes and their impact on brain tissue was performed.
Main Results:
- Inflammation was confirmed as the primary driver of brain injury in progressive MS.
- Distinct pathomechanisms were identified in RRMS and progressive MS, explaining the varying responses to immunomodulatory treatments.
Conclusions:
- Inflammation is a key factor in tissue damage throughout all stages of multiple sclerosis.
- Understanding the different pathomechanisms in RRMS and progressive MS is crucial for developing effective treatments for all disease courses.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
