  • Pim1 is identified as a therapeutic target for inflammatory arthritis, including rheumatoid arthritis (RA) and ankylosing spondylitis (AS).
  • Pim1 expression is elevated in CD4+ T cells in patients with RA or AS and in mouse models of inflammatory arthritis.
  • Conditional knockdown of Pim1 or using the Pim1 inhibitor AZD1208 alleviates inflammatory arthritis by reducing Th17 cell differentiation.
  • Pim1 promotes Th17 cell differentiation by increasing mitochondrial calcium influx, activating oxidative phosphorylation.
  • Nilotinib, an FDA-approved drug, is identified as a potential substitute for Pim1 inhibitors, showing efficacy in reducing Th17 cell differentiation and treating inflammatory arthritis in mouse models.
