UBE2M and systemic lupus erythematosus: Preclinical studies in SLE-prone MRL/lpr mice reveal that JP targets key SLE pathogenic pathways: it restores Th17/Treg balance, suppresses SLE-associated pathogenic B cell proliferation via AKT/mTOR inhibition, and promotes apoptosis of double-negative T cells through UBE2M-mediated Bim upregulation.
