Stable resolvin analogue shows promiseThe chemically stable analogue of resolvin D1 ameliorates experimental autoimmune encephalomyelitis by mediating the resolution of inflammation.
High relevance for autoimmune treatment
We explored the effects of a new, stable form of resolvin D1, called p-MPPF, on autoimmune encephalomyelitis, a condition affecting the nervous system. In our research, both p-MPPF and its unstable counterpart, RvD1, showed significant promise in reducing inflammation and improving symptoms.
This was evidenced by less severe disease progression, better spinal cord health, and changes in immune cell activity. Importantly, we discovered that both substances influenced immune cells in a way that avoids inflammation. Our findings suggest that these types of compounds could lead to improved treatments for autoimmune disorders.

We explored the effect of eicosapentaenoic acid (EPA), a type of omega-3 fatty acid, on systemic lupus erythematosus (SLE), a complex autoimmune disease that causes widespread inflammation in the body. In a carefully designed study using a mouse model of SLE, we discovered that dietary supplementation with EPA-rich fish oil significantly improved various autoimmune symptoms.
Our findings revealed that, after treatment, the mice showed reductions in fluid accumulation, abnormal tissue growth, and levels of certain autoantibodies in their blood. Notably, EPA also led to improvements in kidney health, evidenced by reduced protein levels in urine and decreased inflammation in kidney tissues.
Delving into the mechanisms, we found that EPA influenced how immune cells, particularly B cells, develop. It helped in reducing the overall number of B cells, which are often overactive in autoimmune diseases. Furthermore, EPA encouraged the production of an anti-inflammatory cytokine called IL-10. This is significant because IL-10 plays a crucial role in controlling immune responses and curbing inflammation.
Overall, our research suggests that integrating omega-3 fatty acids like EPA into diets could serve as a promising approach to managing autoimmune conditions, such as SLE. By balancing the intake of omega-3 and omega-6 fatty acids, we may better control the onset and severity of this challenging disease.

Combination therapy shows promiseOmega-3 Polyunsaturated Fatty Acid: A Pharmaco-Nutraceutical Approach to Improve the Responsiveness to Ursodeoxycholic Acid.
Moderate relevance to autoimmune treatment
We set out to understand if adding eicosapentaenoic acid (EPA) to ursodeoxycholic acid (UDCA) could improve outcomes for patients with autoimmune disorders and cholestatic liver diseases. By evaluating how this combination affects key factors like bile acid management, cell apoptosis, and inflammation, we aimed to see if EPA could bolster the effects of UDCA, especially in patients who typically do not respond well to this treatment.
Interestingly, we found that when EPA was combined with a lower dose of UDCA, the results were quite appealing. The combination helped reduce the expression of certain inflammatory genes and showed a notable decrease in cell damage caused by bile acids, even when compared to higher doses of UDCA alone. This means that with EPA, we could potentially achieve better therapeutic outcomes without escalating the drug dosage.
Our findings suggest that incorporating EPA alongside UDCA not only enhances the benefits but could also widen the therapeutic window for patients struggling with liver issues linked to autoimmune disorders. This exciting pharmaco-nutraceutical approach may pave the way for more effective treatments in the future.

We sought to understand how dietary fatty acids, specifically eicosapentaenoic acid (EPA), influence autoimmune diseases like lupus. Through our research on both drug-induced and spontaneous mouse models of lupus, we observed that supplementing with EPA significantly eased symptoms associated with the disease.
Some of the notable improvements included reduced autoantibody production and diminished immunocomplex deposits in the kidneys. Our examinations through lipidomic and membrane dynamics analyses revealed that EPA changes the lipid composition and fluidity of B cell membranes. This adjustment appears to restrict the differentiation of B cells into plasma cells that produce harmful autoantibodies.
Overall, our findings indicate a promising new pathway by which fatty acids like EPA can potentially help manage autoimmunity. This suggests that EPA supplementation might serve as a beneficial treatment option for individuals with lupus.

We aimed to understand how eicosapentaenoic acid, among other metabolites, plays a role in managing autoimmune disorders like rheumatoid arthritis (RA). We tested two specific strains of probiotics, CCFM1074 and CCFM1075, on rats with collagen-induced arthritis to evaluate their impact on immune responses and gut health.
Our findings showed that CCFM1074 significantly eased symptoms of arthritis, while CCFM1075 did not offer similar benefits. Interestingly, both strains helped reduce inflammation markers, notably lowering plasma levels of IL-6 and decreasing the proportion of harmful Th17 cells. However, CCFM1074 stood out by increasing beneficial Treg cells in the mesenteric lymph nodes.
One of the highlights of our study was the role of eicosapentaenoic acid—a metabolite that was notably regulated by CCFM1074. This fatty acid is linked to improving unsaturated fatty acids metabolism, which may contribute to reducing arthritis symptoms. Additionally, CCFM1074 positively influenced the gut microbiota, altering community structures and enhancing beneficial bacteria populations.
Overall, we observed that eicosapentaenoic acid, alongside other factors, could help alleviate arthritis by promoting a healthier gut environment and balancing immune responses.
