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 Glial Fibrillary Acidic Protein (GFAP), comprising:
detecting whether GFAP is present in a biological sample collected from a subject suspected of having a concussion by contacting the biological sample with an anti-GFAP antibody and detecting binding of the antibody to GFAP, wherein said biological sample is a blood, blood plasma, or serum sample, wherein the concussion is induced by a traumatic insult.
2. The method of claim 1 , further comprising detecting ubiquitin C-terminal hydrolase L1 (UCH-L1) in the sample by contacting the sample with an anti-UCH-L1 antibody and detecting binding between the UCH-L1 and the antibody.
3. The method of claim 1 , wherein the traumatic insult is a blow to the head, a gunshot wound, an automobile accident, a sport accident or shaken baby syndrome.
4. The method of claim 1 , wherein said biological sample is serum.
5. The method of claim 1 , wherein said GFAP is detected using an immunoassay.
6. The method of claim 5 , wherein the immunoassay is an ELISA or a sandwich assay.
7. A method for detecting Glial Fibrillary Acidic Protein (GFAP), comprising:
detecting whether GFAP is present in a biological sample collected from a subject suspected of having a concussion by contacting the biological sample with an anti-GFAP antibody and detecting binding of the antibody to GFAP, wherein said biological sample is a blood, blood plasma, or serum sample, wherein the subject is not suspected of having a stroke.
8. The method of claim 7 , further comprising detecting ubiquitin C-terminal hydrolase L1 (UCH-L1) in the sample by contacting the sample with an anti-UCH-L1 antibody and detecting binding between the UCH-L1 and the antibody.
9. The method of claim 7 , wherein said GFAP is detected using an immunoassay.
10. The method of claim 9 , wherein the immunoassay is an ELISA or a sandwich assay.
11. A method for detecting Glial Fibrillary Acidic Protein (GFAP), comprising:
detecting whether GFAP is present in a biological sample collected from a subject suspected of having a concussion by contacting the biological sample with an anti-GFAP antibody and detecting binding of the antibody to GFAP, wherein said biological sample is a blood, blood plasma, or serum sample, wherein the subject is not suspected of having:
reduced blood flow or ischemia that results in deficient blood supply and death of tissues in one area of the brain; or
sudden diminution or loss of consciousness, sensation, and voluntary motion caused by rupture or obstruction of an artery of the brain.
12. The method of claim 11 , further comprising detecting ubiquitin C-terminal hydrolase L1 (UCH-L1) in the sample by contacting the sample with an anti-UCH-L1 antibody and detecting binding between the UCH-L1 and the antibody.
13. The method of claim 11 , wherein said GFAP is detected using an immunoassay.
14. The method of claim 13 , wherein the immunoassay is an ELISA or a sandwich assay.
