AI Technical Summary

Benefits of technology

The patent text describes the discovery of a new gene called Ch25h, which is induced by interferons and is involved in the immune response to viruses. The patent aims to protect the use of this gene and its related proteins for the development of new antiviral therapies that can work against a broad range of viruses. The technical effect of this patent is the discovery and validation of a new gene and its related proteins that can be used to develop new antiviral therapies.

Problems solved by technology

Although these studies support a conserved immunological role of Ch25h and 25HC, their roles in the immune system remain elusive.

Abstract

This invention relates, e.g., to a method for inhibiting the growth and / or proliferation and / or infectivity of a virus in a cell, such as a mammalian cell (e.g. for inhibiting entry of the virus into the cell), comprising administering, or causing to be administered, to the cell, 25-hydroxycholesterol (25HC) in an amount sufficient to inhibit the growth and / or proliferation and / or infectivity of the virus in the cell. The method can be carried out in vivo or in vitro. Among the viruses that can be inhibited are, e.g., VSV, HSV, MHV68, HCV, HIV, EBOV, RVFV, RSSEV and Nipah virus. In one embodiment of the invention, the 25HC is administered topically, e.g. to a mucosal surface.

Description

[0001]This application claims the benefit of the filing date of U.S. Provisional application 61 / 643,110, filed May 4, 2012, which is incorporated by reference herein in its entirely.SEQUENCE LISTING[0002]The instant application contains a Sequence Listing which has been submitted in ASCII format via EFS-Web and is hereby incorporated by reference in its entirety. Said ASCII copy, created on May 3, 2013, is named 58086-347965_SL.txt and is 3,313 bytes in size.BACKGROUND INFORMATION[0003]Viruses are obligate intracellular pathogens that—despite having unique structure and function—undergo lifecycle stages of entry, replication, protein synthesis, assembly, and egress. Upon specific binding to cell surface molecules, non-enveloped virus can enter the cell directly while enveloped viruses undergo fusion process that requires specific interactions between the viral and cellular receptors and membranes. After entry, viral components are released into the cytoplasm and may enter the nucleu...
