Multiple sclerosis (MS) is a neuroinflammatory condition that affects the central nervous system and presents with various neurological and cognitive symptoms. Although these symptoms and the disease course of MS can vary considerably among affected individuals, most people with this condition exhibit a progressive accumulation of disability in the later phase of the disease. This poster provides an overview of the pathophysiological contributions of both the immune system and the nervous system to MS and how these contributions change with disease progression. The poster also highlights the sites of action of the currently available drugs for MS and briefly touches on other therapeutic strategies that are being explored.
Research from JAMA Neurology — Vaccines and the Risk of Multiple Sclerosis and Other Central Nervous System Demyelinating Diseases
Gilbert C FAURE's insight:
Results We identified 780 incident cases of CNS ADS and 3885 controls; 92 cases and 459 controls were females aged 9 to 26 years, which is the indicated age range for HPV vaccination. There were no associations between HepB vaccination (odds ratio [OR], 1.12; 95% CI, 0.72-1.73), HPV vaccination (OR, 1.05; 95% CI, 0.62-1.78), or any vaccination (OR, 1.03; 95% CI, 0.86-1.22) and the risk of CNS ADS up to 3 years later. Vaccination of any type was associated with an increased risk of CNS ADS onset within the first 30 days after vaccination only in younger (<50 years) individuals (OR, 2.32; 95% CI, 1.18-4.57).
Conclusions and Relevance We found no longer-term association of vaccines with MS or any other CNS ADS, which argues against a causal association. The short-term increase in risk suggests that vaccines may accelerate the transition from subclinical to overt autoimmunity in patients with existing disease. Our findings support clinical anecdotes of CNS ADS symptom onset shortly after vaccination but do not suggest a need for a change in vaccine policy.
Blood-borne monocyte derived cells play a pivotal, initially unrecognized, role in most central nervous system disorders, including diseases initially classified as purely neurodegenerative (i.e. AD, PD, and ALS).
Gilbert C FAURE's insight:
Extracellular vesicles, namely exosomes and shed vesicles, are released by virtually any cell type and can be detected and identified in terms of cell origin in biological fluids. They therefore constitute an ideal tool to access information on cells residing in an inaccessible site such as the brain. We will review here available information on extracellular vesicles detection in neurological disorders with special emphasis on neurodegenerative diseases.
