Pharmaceutical use of FAM19A5 involved in regulating gliogenesis
The present invention relates to the pharmaceutical use of FAM19A5 involved in regulating gliogenesis, and more specifically, to the use of FAM19A5 in the prevention, diagnosis, or treatment of central nervous system injuries, degenerative brain diseases, or central nervous system diseases, FAM19A5 being spread in the neural stem cells in vertebrates and regulating gliogenesis.
1. A method of treating a glioblastoma in a subject in need thereof, comprising administering to the subject an effective amount of an antibody or a fragment thereof that specifically binds to a family with sequence similarity 19 (FAM19A5) protein (anti-FAM19A5 antibody).
2. The method of claim 1 , wherein the anti-FAM19A5 antibody is a monoclonal antibody.
3. The method of claim 2 , wherein the monoclonal antibody is a humanized antibody.
4. The method of claim 2 , wherein the monoclonal antibody is a human antibody.
5. The method of claim 1 , wherein the fragment thereof comprises a Fab, Fab′, F(ab′)2, Fv fragment, diabody, linear antibody, single chain antibody, multispecific antibody formed from the antibody fragment, or combinations thereof.
6. A method of treating a brain tumor in a subject in need thereof, comprising administering to the subject an effective amount of an antibody or a fragment thereof that specifically binds to a family with sequence similarity 19 (FAM19A5) protein (anti-FAM19A5 antibody), wherein the brain tumor is caused by a gliosis resulting from damage of the central nervous system.
7. The method of claim 6 , wherein the anti-FAM19A5 antibody is a monoclonal antibody.
8. The method of claim 7 , wherein the monoclonal antibody is a humanized antibody.
9. The method of claim 7 , wherein the monoclonal antibody is a human antibody.
10. The method of claim 6 , wherein the fragment thereof comprises a Fab, Fab′, F(ab′)2, Fv fragment, diabody, linear antibody, single chain antibody, multispecific antibody formed from the antibody fragment, or combinations thereof.
11. A method of treating a brain tumor in a subject in need thereof, comprising administering to the subject an effective amount of an antibody or a fragment thereof that specifically binds to a family with sequence similarity 19 (FAM19A5) protein (anti-FAM19A5 antibody), wherein the brain tumor is associated with (i) an onset of reactive astrocytes, (ii) an increase in the number of oligodendrocyte progenitor cells expressing neuron-glial antigen 2 (NG2), (iii) a decrease in TuJ-positive neuron development, or (iv) combinations thereof.
12. The method of claim 11 , wherein the anti-FAM19A5 antibody (i) delays the onset of reactive astrocytes, (ii) decreases the number of oligodendrocyte progenitor cells expressing NG2, (iii) increases TuJ-positive neuron development, or (iv) combinations thereof in the subject.
13. The method of claim 11 , wherein the anti-FAM19A5 antibody is a monoclonal antibody.
14. The method of claim 13 , wherein the monoclonal antibody is a humanized antibody.
15. The method of claim 13 , wherein the monoclonal antibody is a human antibody.
16. The method of claim 11 , wherein the fragment thereof comprises a Fab, Fab′, F(ab′)2, Fv fragment, diabody, linear antibody, single chain antibody, multispecific antibody formed from the antibody fragment, or combinations thereof.
