Professor Jin Kyun Park's research lab focuses on autoimmune and inflammatory rheumatic diseases, with a primary emphasis on rheumatoid arthritis (RA) and systemic sclerosis (SSc). The lab investigates novel therapeutic targets and molecular mechanisms underlying chronic inflammation, osteoclastogenesis, and immune cell dysfunction, particularly in B cells, monocytes, and regulatory T cells. Key research directions include the development and preclinical evaluation of small-molecule inhibitors—such as Btk and HDAC6 inhibitors—for autoimmune conditions, as well as exploring the role of angiogenesis and bone remodeling in disease progression. The lab also contributes to international consensus efforts in patient-reported outcome measures for inflammatory myopathies.

HM71224 inhibits Btk in B cells and monocytes and ameliorates experimental arthritis in a mouse model. Thus, HM71224 is a potential novel therapeutic agent for rheumatoid arthritis in humans.
The coronavirus disease 2019 (COVID-19) pandemic has caused more than 100 million infections and 2 million deaths worldwide. In up to 20% of cases, COVID-19 infection can take a severe, life-threatening course. Therefore, preventive measures such as mask-wearing, hand hygiene, and social distancing are important. COVID-19 vaccines that use novel vaccine technology can prevent up to 95% of infections. However, the uncertainty regarding the efficacy and safety of vaccination in patients with autoi
The novel HDAC6 inhibitor CKD-506 suppresses inflammatory responses by monocytes/macrophages, improves Treg function, and ameliorates arthritis severity in a murine model of RA. Thus, CKD-506 might be a novel and effective treatment option for RA.
Our findings indicate that increased osteoclast formation and higher VEGF levels may contribute to AO in SSc patients. Further studies are needed to elucidate whether targeting osteoclastogenesis may provide a specific therapeutic option for SSc-associated AO.
Further prioritization and a reduction in the number of domains will be needed for the next Delphi. At the next biennial OMERACT meeting, we aim to present and seek voting on a Myositis Preliminary PRO Core Set to enable ultimate measure selection and development.
Expression of TRAP and cathepsin K is a general feature of MNGs and their expression might be related to histopathological pattern.
Lipoproteins from SLE patients exhibited greater oxidative potential, which might contribute to accelerated atherosclerosis in SLE.
RA and DM/PM seemed to be associated with a higher mortality in patients with lung or breast cancers, whereas SSc seemed to be associated with decreased mortality in patients with lung cancer. It is warranted to explore the survival effect of tailored cancer treatments according to specific RD.
CD70(+) CD4 T cells are enriched in RA and may directly contribute to RA pathogenesis by producing IFN-γ and IL-17. Targeting CD70(+) CD4 T cells might offer new therapeutic opportunities in RA.
MNGs in granulomata in the GPA lung express osteoclastic enzymes TRAP and cathepsin K. GPA patients have a higher propensity to form TRAP+ MNGs from peripheral blood than healthy controls. These data suggest that (i) the tendency to form MNGs is a component of the GPA phenotype itself, and (ii) that lesional MNGs might participate in the destructive process through their proteolytic enzymes.
