Abstract

The current invention provides novel approaches to the treatment of various disease states that lead to altered cytokine release or cytokine storms. These diseases include viral infections immunological and other non-immunological diseases. Specifically, the invention provides methods targeting ZHX2 including methods of inhibition, blocking or depletion of ZHX2 in order to treat various disease states.

First claim

1 . A method for treating a disease in a patient in need thereof comprising the administration of an inhibitor of ZHX2 to the patient, wherein the administration of an inhibitor of ZHX2, wherein the administration of an inhibitor of ZHX2 leads to the depletion of ZHX2 in the patient.

2 . The method of claim 1 , where in the disease to be treated is selected from the group consisting of inflammatory and non-inflammatory diseases that affect cytokine release including viral infections like SARS-Cov-1, SARS-Cov-2, other coronaviruses, influenza, parainfluenza, Respiratory Syncytial Virus, adenoviruses, enteroviruses, cytomegalovirus (CMV), Epstein Barr Virus (EBV), Middle East Respiratory Syndrome (MERS), and Ebola, non-respiratory viral infections, non-viral infections like bacterial, fungal and parasitic infections, immune-mediated disorders, cardiovascular pathology, diabetes, metabolic syndrome, organ transplantation, neurodegeneration, and cancer, and aging.

3 . The method of claim 1 , wherein the inhibitor of ZHX2 is selected from the group consisting of agent comprising an adeno-associated virus (AAV) or lentovirus-containing an a short-hairpin RNA (shRNA), an antibody or antibody fragment directed against ZHX2, an siRNA or other antisense oligonucleotide that targets ZHX2, and an antagonist that binds to a ZHX2-mediated receptor.

4 . The method of claim 3 , wherein shRNA is attached to or part of a vector.

5 . The method of claim 4 , wherein the vector is selected from the group consisting of plasmids, viral vectors, bacteriophages, cosmids, and artificial chromosomes.

6 . The method of claim 3 , wherein the antibody or antibody fragment directed against the one or more antibodies selected from the group consisting of a polyclonal antibody, a monoclonal antibody and a bivalent antibody.

7 . The method of claim 3 , wherein an inhibitor of ZHX2 is one or more DNA fragments encoding a ZHX2 gene that has been modified.

8 . The method of claim 7 , wherein the one or more DNA fragments encoding a ZHX2 gene that has been modified by CRISPR

9 . The method of claim 2 , wherein the disease to be treated is a disease that causes an increased release of cytokines.

10 . The method of claim 2 , wherein the respiratory viral infection is the result of an infection by SARS-COV-2.

11 . The method of claim 1 , wherein the administration of the ZHX2 inhibitor leads to a ZHX2 hypomorph state in the patient being treated.

12 . The method of claim 1 , further comprising altered activation of STAT5, STAT6 or NFκB proteins.

13 . A method for inhibiting, neutralizing or depleting ZHX2 in a patient in need thereof comprising the administration of a pharmacological agent, wherein the pharmacological agent binds or interacts with the ZHX2 gene and wherein the binding of the pharmacological agent makes reversible or irreversible changes to the ZHX2 gene.

14 . The method of claim 13 , wherein the pharmacological agent binds or interacts with the ZHX2 gene directly.

15 . The method of claim 13 , wherein the pharmacological agent binds or interacts with the ZHX2 gene indirectly either upstream or downstream of the ZHX2 gene.

16 . A method for reducing or silencing ZHX2 gene expression in a patient in need thereof comprising the administration of a pharmacological agent, wherein the pharmacological agent inhibits or blocks a protein that interacts with ZHX2 in the nucleus of a cell.

17 . The method of claim 16 , wherein the protein that interacts with ZHX2 in the nucleus is selected from one or more of ZHX1, ZHX3, Nuclear Factor-YA, Nuclear Factor-YB, Nuclear Factor-YC, FoxCI and ephrin-B1/B2 or any other protein known to interact with ZHX2.

18 . The method of claim 16 , wherein the pharmacological agent that inhibits or blocks a protein that interacts with ZHX2 in the nucleus of a cell causes reversible or irreversible changes to the ZHX2 gene expression.

19 . The method of claim 13 , wherein the administration of the pharmacological agent leads to a ZHX2 hypomorph state in the patient being treated.

20 . The method of claim 16 , wherein the administration of the pharmacological agent leads to a ZHX2 hypomorph state in the patient being treated.
