New Biomarkers for Atherothrombosis in Antiphospholipid Syndrome: Genomics and Epigenetics Approaches
Conclusions In recent years, there have been many advances in the understanding of the molecular basis for vascular involvement in APS, but many areas need to be further investigated, in particular the association between altered genetic/epigenetic profiles, autoantibodies and clinical manifestations, and the effectiveness of new therapeutic strategies. It would be interesting to apply next generation sequencing technologies like RNA-Seq along with GWAS to screen both, the gene profile and the whole transcriptome of large cohorts of primary APS patients, in order to reveal the mutations/polymorphisms, post-transcriptiona...

Subclinical Atherosclerosis in Primary Sj ögren's Syndrome: Does Inflammation Matter?
Conclusions The markers of endothelial activation and damage and of chronic inflammation investigated until now failed to result predictors of subclinical atherosclerosis or to be associated with increased risk of CV events in SS patients. This may suggest that other mechanisms are implicated with increased prevalence of subclinical atherosclerosis in SS or that these biomarkers exert a different mechanism in the pathogenesis of endothelial damage and in the induction of atherosclerosis. Surely, the relationship between the disease itself and inflammatory and immune dysfunction factors is quite complex and still to be cla...

Astragaloside IV protects blood-brain barrier integrity from LPS-induced disruption via activating Nrf2 antioxidant signaling pathway in mice.
Abstract Endothelial cells of cerebral microvessels are one of the components of blood-brain-barrier (BBB), which are connected by tight junctions (TJs). BBB disruption in cerebral diseases such as ischemic stroke, Alzhemer's disease, multiple sclerosis and traumatic brain injury is implicated to exacerbate the disease progression. Astragaloside IV (ASIV) isolated from Astragalus membranaceus prevents BBB breakdown in rodents induced with cerebral edema and experimental autoimmune encephalomyelitis. However, its underlying molecular mechanism has not been elucidated yet. In present study, ASIV was found to prevent...

Melatonin improves memory defects in a mouse model of multiple sclerosis by up-regulating cAMP-response element-binding protein and synapse-associated proteins in the prefrontal cortex.
Abstract Multiple sclerosis is a progressive autoimmune disorder of the myelin sheath and is the most common inflammatory disease of young adults. Up to 65% of multiple sclerosis patients have cognitive impairments such as memory loss and difficulty in understanding and maintaining attention and concentration. Many pharmacological interventions have been used to reverse motor impairments in multiple sclerosis patients; however, none of these drugs improve cognitive function. Melatonin can diffuse through the blood-brain barrier and has well-known antioxidant and anti-inflammatory properties with almost no side eff...

1,2,4-Trimethoxybenzene selectively inhibits NLRP3 inflammasome activation and attenuates experimental autoimmune encephalomyelitis
In conclusion, our results demonstrate that 1,2,4-TTB is an NLRP3 inflammasome inhibitor and attenuates the clinical symptom and inflammation of EAE, suggesting that 1,2,4-TTB is a potential candidate compound for treating NLRP3 inflammasome-driven diseases, such as multiple sclerosis.PMID:33627802 | DOI:10.1038/s41401-021-00613-8
