Abstract

Official abstract text for this publication.

The present invention relates to a composition for treating inflammatory brain diseases, which includes stem cell-derived exosomes as an active ingredient. The stem cell-derived exosomes according to the present invention can be usefully applied to the treatment of inflammatory brain diseases, because the exosomes have outstanding therapeutic effects, including inhibiting cell death due to inflammation in nerve cells, increasing the survival rate in an inflammatory-brain-disease animal model, and substantially reducing brain damage and inflammatory cytokine levels due to inflammatory reactions such as edema.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for treating an inflammatory brain disease, comprising: administering to a subject in need thereof an effective amount of exosome derived from a stem cell, wherein the inflammatory brain disease is selected from the group consisting of encephalitis, encephalomeningitis, and meningoencephalitis, and wherein the stem cell is a mesenchymal stem cell. 2. The method according to claim 1 , wherein the mesenchymal stem cell is derived from one or more tissues selected from the group consisting of umbilical cord, cord blood, bone marrow, fat, muscle, nerve, skin, amnion, and placenta. 3. The method according to claim 1 , wherein the encephalomeningitis is induced by one or more infectious agents selected from the group consisting of bacteria, parasites, fungi, protozoa, and viruses. 4. The method according to claim 3 , wherein the encephalomeningitis is bacterial infection-induced encephalomeningitis. 5. The method according to claim 1 , wherein the composition further comprises the internal contents of exosomes in addition to exosomes. 6. The method according to claim 1 , wherein the composition is administered orally, rectally, intravascularly, intramuscularly, subcutaneously, intrauterinely, cerebrovascularly, or intraventricularly. 7. The method according to claim 1 , wherein the stem cell is treated with thrombin. 8. The method according to claim 1 , wherein the exosome is administered in a pharmaceutical composition containing a pharmaceutically acceptable carrier.
