How B cells and other immune cells drive psoriatic arthritis
Immune cell contributions to inflammatory arthritis
This project explores how certain immune B cells and other immune cells cause inflammation and joint damage in people with psoriatic arthritis.

What this research studies
This research uses a mouse model that closely mimics human psoriatic arthritis and compares those findings to cells and tissues seen in patients. Scientists will examine B cells, T cells, and antigen-presenting cells in inflamed joints and measure key inflammatory proteins such as IL-6 and IL-10. They will test what happens when B cells are reduced or shifted toward anti- or pro-inflammatory types and look for resulting changes in joint inflammation and bone erosion. Findings from the mice will be connected to observations from psoriatic arthritis patients to suggest targets for new treatments.
Who could benefit from this research
Good fit: Ideal candidates would be adults with a confirmed diagnosis of psoriatic arthritis, especially those with active joint inflammation, dactylitis, or enthesitis.
Not a fit: People without psoriatic arthritis or with skin-only psoriasis, or those with unrelated forms of arthritis, are unlikely to directly benefit from this specific research.
Why it matters
Potential benefit: If successful, this work could point to new ways to treat or prevent joint damage in psoriatic arthritis by targeting specific B cell types or their inflammatory signals.
How similar studies have performed: Some patients have shown improvement with B cell–targeting drugs like rituximab, but using a disease-mimicking mouse model to define exact B cell roles in psoriatic arthritis is a relatively new approach.
