Protein kinase domain of the large subunit of herpes simplex type 2 ribonucleotide reductase (icp 10pk) has anti-apoptotic activity
View Patent ↗The invention relates to a method of treating neuronal apoptosis in a mammal using nucleic acid encoding HSV-2 ICP10PK, or a polypeptide encoded thereby. The invention further relates to a method of treating neuronal apoptosis in a mammal using ICP10PK in combination with a nucleic acid encoding bcl-2, or the polypeptide encoded thereby. The invention also relates to the use of ICP10PK and ICP10PK in combination with bcl-2 to treat non-neuronal diseases characterized by apoptosis.
1. A method of inhibiting neuronal apoptosis in a mammal, comprising administering to said mammal an apoptosis-inhibiting amount of a polypeptide consisting of amino acids 1 to 411 of SEQ ID NO: 2 wherein said polypeptide is administered directly into cells.
2. A method of inhibiting neuronal apoptosis in a mammal, comprising administering to said mammal an apoptosis-inhibiting amount of a polypeptide consisting of amino acids 1 to 411 of SEQ ID NO: 2 fused to a bcl-2 polypeptide, or a mutant, variant, homolog, or fragment thereof having anti-apoptotic activity wherein said polypeptide is administered directly into cells.
3. The method of claim 1 , wherein said neuronal apoptosis is associated with a neurodegenerative disorder.
4. The method of claim 3 , wherein said neurodegeneranve disorder is Alzheimer's disease (AD), lateral sclerosis (ALS), Down syndrome (DS), diabetic neuropathy, Parkinson's disease (PD) or Huntington disease (HD).
5. The method of claim 1 , wherein said neuronal apoptosis is associated with an injury of the central or peripheral nervous system.
6. The method of claim 5 , wherein said injury is a result of stroke, cerebral ischemia, or chemical and/or physical trauma.
7. The method of claim 1 , additionally comprising administering a polypeptide encoded by a nucleic acid encoding bcl-2 or any mutant, variant, homolog, or fragment thereof having anti-apoptotic activity.
8. A method of inhibiting apoptosis in a mammal comprising administering to said mammal an apoptosis-inhibiting amount of a polypeptide which consists of amino acids 1 to 411 of SEQ ID NO: 2 wherein said polypeptide is administered directly into cells.
9. A method of inhibiting apoptosis in a mammal, comprising administering to said mammal an apoptosis-inhibiting amount of a polypeptide consisting of amino acids 1 to 411 of SEQ ID NO: 2 fused to a bcl-2 polypeptide, or any mutant, variant, homolog, or fragment thereof having anti-apoptotic activity wherein said polypeptide is administered directly into cells.
