  • Publication number: 20250295704
    Abstract: Provided is a composition for the treatment of osteoarthritis using iPSC-derived mitochondria. Therefore, it was confirmed that the iPSC-derived mitochondria of the present disclosure increased the transplant ability into chondrocytes, suppressed the expression of the MMP series, which were cartilage metabolic factors, and suppressed the death of chondrocytes. In addition, it was confirmed that the iPSC-derived mitochondria suppressed damage to joint tissue in an osteoarthritis animal model, reduced immune cells, and increased immune osteoarthritis-causing regulatory cells. In addition, it was confirmed that the expression of UCP2 in iPSC-derived mitochondria was significantly increased compared to mitochondria isolated from other origin cells, and that UCP2 was closely related to the treatment effect of osteoarthritis caused by mitochondrial transplantation. In addition, it was confirmed that iPSC-derived mitochondria overexpressing UCP2 improves osteoarthritis as a cartilage regeneration effect.

  • Publication number: 20240131027
    Abstract: The present invention relates to a pharmaceutical composition comprising a novel compound as an active ingredient for prevention or treatment of transplant rejection. The novel compound SD911 of the present invention was identified to repress the migration of immune cells, increase the engraftment and viability of a grafted tissue, and regulate immune cells. In addition, it was found in a kidney transplantation model that the compound restrained human PBMC from suppressing the engraftment and damaging renal tissues and downregulated the expression of the inflammatory cytokine IL-17, with the consequent effective prevention and treatment of transplant rejection.
