  • Publication number: 20220211762
    Abstract: The present invention relates to a pharmaceutical composition for the treatment of sepsis or systemic inflammatory response syndrome (SIRS) comprising mitochondria as effective ingredient. When activated macrophages and monocytes are treated with mitochondria which are effective ingredient of the pharmaceutical composition of the present invention, expression of IL-1?, TNF-? and IL-6 which are pro-inflammatory cytokines can be restored to normal levels. Furthermore, when the pharmaceutical composition of the present invention is administered to a subject suffering from sepsis, the survival rate of the subject can be remarkably increased. Therefore, the pharmaceutical composition according to the present invention can be useful for the treatment of sepsis.

  • Publication number: 20210052659
    Abstract: The present invention relates to a pharmaceutical composition for prevention or treatment of rheumatoid arthritis and, more particularly, to a pharmaceutical composition comprising mitochondria as an effective ingredient for prevention or treatment of rheumatoid arthritis. When a foreign mitochondria pharmaceutical composition of the present invention is administered to a subject suffering from rheumatoid arthritis, the subject may alleviate edema and rubefaction symptoms. In addition, the pharmaceutical composition of the present invention reduces an expression level of the inflammatory cytokine IL-6, but increases an expression level of the anti-inflammatory cytokine IL-10 in the subject. Therefore, the pharmaceutical composition according to the present invention can be effectively used for preventing or treating rheumatoid arthritis.
