Neural proteins as biomarkers for nervous system injury and other neural disorders
The present invention identifies biomarkers that are diagnostic of nerve cell injury and/or neuronal disorders. Detection of different biomarkers of the invention are also diagnostic of the degree of severity of nerve injury, the cell(s) involved in the injury, and the subcellular localization of the injury.
1. A method for detecting Ubiquitin C-terminal Hydrolase L1 (UCH-L1), comprising:
detecting whether UCH-L1 is present in a biological sample collected from a subject suspected of having a traumatic brain injury (TBI) by contacting the biological sample with an anti-UCH-L1 antibody and detecting binding of the antibody to UCH-L1.
2. The method of claim 1 , wherein the biological sample is cerebrospinal fluid (CSF), blood, plasma, or serum.
3. The method of claim 2 , wherein the biological sample is blood, plasma, or serum.
4. The method of claim 3 , wherein the biological sample is blood.
5. The method of claim 3 , wherein the biological sample is plasma.
6. The method of claim 3 , wherein the biological sample is serum.
7. The method of claim 1 , wherein UCH-L 1 is detected using an immunoassay.
8. The method of claim 7 , wherein the immunoassay is an enzyme-linked immunosorbent assay (ELISA) or a sandwich assay.
9. The method of claim 8 , wherein the immunoassay is an ELISA.
10. The method of claim 2 , further comprising detecting Glial Fibrillary Acidic Protein (GFAP) in the biological sample by contacting the biological sample with an anti-GFAP antibody and detecting binding of the antibody to GFAP.
11. A method for detecting Ubiquitin C-terminal Hydrolase L1 (UCH-L1), comprising:
detecting whether UCH-L1 is present in a biological sample collected from a subject suspected of having a traumatic brain injury (TBI) by contacting the biological sample with an anti-UCH-L1 antibody and detecting binding of the antibody to UCH-L1, wherein the TBI is caused by a traumatic insult.
12. The method of claim 11 , wherein the traumatic insult is a blow to the head, a gunshot wound, an automobile accident, a sport accident, or shaken baby syndrome.
13. The method of claim 11 , wherein the biological sample is cerebrospinal fluid (CSF), blood, plasma, or serum.
14. The method of claim 13 , wherein the biological sample is blood, plasma, or serum.
15. The method of claim 14 , wherein the biological sample is blood.
16. The method of claim 14 , wherein the biological sample is plasma.
17. The method of claim 14 , wherein the biological sample is serum.
18. The method of claim 11 , wherein UCH-L 1 is detected using an immunoassay.
19. The method of claim 18 , wherein the immunoassay is an enzyme-linked immunosorbent assay (ELISA) or a sandwich assay.
20. The method of claim 11 , further comprising detecting Glial Fibrillary Acidic Protein (GFAP) in the biological sample by contacting the biological sample with an anti-GFAP antibody and detecting binding of the antibody to GFAP.
