Inflammatory joint macrophages were silenced in mice, not in a clinic

What the research found
News-Medical reported on 28 October 2026 a Science Translational Medicine paper by Rui Peng and colleagues (DOI 10.1126/scitranslmed.adz4081). Single-cell sequencing of mouse synovium and samples from people with osteoarthritis found an expanded group of inflammatory macrophages that carry CD74 and gather where synovium meets cartilage. CD74 partnered with the enzyme ENO2. Lipid nanoparticles carrying silencing RNA against CD74 calmed those cells in a dish and reduced synovial inflammation and disease progression in mice. That intervention is a mouse experiment, not a joint treatment for people. Ages and sex of the human samples were not given in the report. Not medical advice.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
