- Helps reduce inflammation in rheumatoid arthritis.
- Reprograms macrophages for better anti-inflammatory response.
- Potential for treating other inflammatory diseases.
Beijing, March 14 (NationPress) A team of researchers from northern China's Tianjin University has created a groundbreaking injectable hydrogel designed to regulate immune cell metabolism, thereby aiding in the reduction of inflammation and the progression of rheumatoid arthritis.
Rheumatoid arthritis is a chronic and debilitating condition characterized by painful symptoms. It arises when the immune system erroneously attacks healthy joints, which can lead to significant deformities and disabilities, posing challenges for millions globally, according to Xinhua news agency.
The researchers identified that a crucial aspect of this issue is the metabolism of immune cells, especially macrophages. When the metabolic pathways of these cells become unbalanced, they emit excessive inflammatory signals that exacerbate the condition. Regulating this metabolism could pave the way for novel therapeutic approaches for rheumatoid arthritis.
The newly developed hydrogel is composed of biodegradable alginate and features a unique dual-network structure, facilitating easy injection and controlled release of therapeutic agents.
Upon injection into the joint, the hydrogel interacts with the acidic environment characteristic of inflammation, gradually releasing zinc ions and small interfering RNA.
These compounds assist in reprogramming the metabolism of macrophages, diminishing their inflammatory response while boosting their anti-inflammatory capabilities.
“This marks the first instance where metabolic reprogramming has been utilized in the treatment of rheumatoid arthritis, and we are optimistic about its potential application to other inflammatory conditions in the future,” stated Li Nan, the team leader.
The results were recently published in Advanced Functional Materials.
“Our aim is to not only offer a more effective treatment for RA but also to investigate innovative methods for addressing inflammation-related disorders at the metabolic level,” Nan added.
This cutting-edge hydrogel represents a beacon of hope for RA patients, potentially transforming the battle against this formidable illness.
