Methods of treating neurological conditions with hematopoietic growth factors
The present invention relates to a method of treating neurological conditions in a mammal by administering a hematopoietic growth factor such as granulocyte-colony stimulating factor (GCSF) and granulocyte-macrophage colony stimulating factor (GMCSF). The invention also provides methods of screening for compounds that bind to a GCSF or GMCSF receptor found on the surface of a neuronal cell; and which provides a neuroprotective, neuroproliferative and/or a STAT gene activation activity.
1. A method of treating traumatic brain injury in a mammal suffering from traumatic brain injury, comprising
administering to the mammal suffering from traumatic brain injury, human G-CSF, or a protein having at least 90% homology to SEQ ID NO:38 in an amount sufficient to treat the traumatic brain injury; and
assessing neurological function in the mammal after said administering.
2. The method of claim 1 , wherein human G-CSF is administered.
3. The method of claim 1 , wherein the mammal treated is human.
4. The method of claim 1 , wherein the human G-CSF, or a protein having at least 90% homology to SEQ ID NO:38 is administered by one or more modes of administration selected from the group consisting of direct intracerebral injection, intravenously, intraarterially, orally, and subcutaneously.
5. A method of treating traumatic brain injury in a mammal suffering from traumatic brain injury, comprising intravenously administering to the mammal suffering from traumatic brain injury, human G-CSF, or a protein having at least 90% homology to SEQ ID NO:38 in an amount sufficient to treat the traumatic brain injury; and
assessing neurological function in the mammal after said administering.
6. The method of claim 5 , comprising intravenously administering human G-CSF.
7. The method of claim 5 , comprising intravenously administering a protein having at least 90% homology to SEQ ID NO:38.
8. The method of claim 5 , comprising intravenously administering a protein having at least 95% homology to SEQ ID NO:38.
9. The method of claim 1 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:37, SEQ ID NO:38, or SEQ ID NO:39.
10. The method of claim 5 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:37, SEQ ID NO:38, or SEQ ID NO:39.
11. The method of claim 9 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:38.
12. The method of claim 10 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:38.
13. A method of improving neurological function in a mammal suffering from traumatic brain injury, comprising administering to the mammal suffering from traumatic brain injury, human G-CSF, or a protein having at least 90% homology to SEQ ID NO:38 in an amount sufficient to improve neurological function compared to the mammal prior to administering; and assessing neurological function in the mammal after said administering.
14. The method of claim 13 , wherein human G-CSF is administered.
15. The method of claim 13 , wherein the mammal suffering from traumatic brain injury is human.
16. The method of claim 13 , wherein the human G-CSF, or a protein having at least 90% homology to SEQ ID NO:38 is administered by one or more modes of administration selected from the group consisting of direct intracerebral injection, intravenously, intraarterially, orally, and subcutaneously.
17. The method of claim 16 , wherein the mode of administration is intravenously.
18. The method of claim 13 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:37, SEQ ID NO:38, or SEQ ID NO:39.
19. The method of claim 18 , wherein human G-CSF has the amino acid sequence in SEQ ID NO:38.
