d-mannose may alleviate psoriasis
We explored whether d-mannose can help alleviate psoriasis, an autoimmune condition that causes significant discomfort. Our study demonstrated that both oral and topical applications of d-mannose were effective in reducing psoriasis symptoms in mice.

We discovered that it works by lowering levels of a protein called HIF-1α and the chemokine CCL20 in skin cells. This inhibition interrupts the harmful cycle between keratinocytes and Th17 immune cells. Overall, this suggests d-mannose could be a helpful treatment option for managing psoriasis.

We examined how D-mannose impacts ulcerative colitis (UC) in a mouse model designed to mimic human inflammatory bowel disease. Our findings reveal that D-mannose significantly lessens UC symptoms by reducing inflammation and oxidative stress. Notably, it increases regulatory T (Treg) cell levels, which are crucial in controlling immune responses. This study is the first to show D-mannose's therapeutic potential for UC, bringing newfound hope for managing this condition.

D-mannose shows therapeutic promise
We investigated how sodium oligomannate affects autoimmune encephalomyelitis in mice and its role in altering gut bacteria and microglial behavior. Mice were divided into groups, with some receiving varying doses of sodium oligomannate.

Results showed improved symptoms and reduced disease severity in the treatment groups compared to the control. Specifically, changes in inflammatory markers and gut flora ratios were noted, indicating that higher doses yielded better outcomes.

Overall, sodium oligomannate demonstrated a promising, dose-dependent therapeutic effect on autoimmune disorders.

After trying LifeSeasons, Urinari-X, I opted for D-mannose and Cranberries due to persistent cystitis linked to my autoimmune disorder. I found these alternatives to be cost-effective and lasted longer. By taking one of each tablet twice daily throughout winter, I avoided severe attacks. This treatment truly deserves a high rating.

After suffering with cystitis for over 10 years, I finally found relief. Antibiotics frequently failed to help, but D-mannose proved effective against my recurring autoimmune disorder. I took three capsules daily at the first signs of trouble, successfully preventing exacerbations. I wholeheartedly recommend D-mannose—it's a miracle for those afflicted.

After years of chronic cystitis and countless antibiotic injections, I persuaded my mother to use D-mannose, alongside probiotics and other supplements for her autoimmune disorder. Miraculously, she experienced significant improvements in her condition. The frequency of cystitis attacks reduced, and her overall gut health improved. A truly effective natural remedy.

We explored how engineered antibodies using mannose 6-phosphate analogs can enhance treatment for autoimmune and inflammatory disorders. Through a clever design, these antibodies target both harmful proteins and specific receptors on cells, which allows for greater internalization and degradation of these proteins.

Our studies showed that this new approach greatly increased the effectiveness of antibodies like infliximab and bevacizumab, making them much better at inhibiting their targets. This innovative strategy could pave the way for more effective treatments in autoimmunity and inflammation.

Mannose enhances methotrexate delivery
We explored an innovative approach to treating rheumatoid arthritis (RA) using mannose-targeted methotrexate delivery systems. This strategy involved creating chimaeric polymersomes that deliver higher amounts of methotrexate directly to macrophages.

The results showed that this method led to improved uptake by activated macrophages, promoting a shift towards healthier anti-inflammatory responses. It also reduced the production of harmful cytokines, effectively protecting joint tissues from damage. Overall, mannose-mediated delivery presents a promising enhancement to RA therapy.
