Immune-mediated rheumatoid arthritis: from single-cell genomics to new therapies.

Single-cell genomics reveals diverse pathogenic immune cell subsets in rheumatoid arthritis, paving the way for targeted therapies.

• Why it matters: Understanding the causal mechanisms behind immune-mediated arthritis remains challenging despite detailed cellular data, limiting the development of effective treatments.
• What they did: The authors review emerging data and propose integrating spatial transcriptomics, ex vivo mechanistic studies, organoids, and refined animal models based on human disease data to deepen insights into rheumatoid arthritis.
• The result: These approaches can identify disease mechanisms and inform the design of new therapies and clinical trials, with potential applications across other immune-mediated conditions.
