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. Here, AKT1 is linked to systemic lupus erythematosus.
