Abstract: Provided are compositions that include lipid particles, such as liposomes, that can fuse with the ER membrane of a cell. The lipid particles can also deliver a cargo, such as a therapeutic or an imaging agent, encapsulated inside the particles inside the ER lumen of the cell. The compositions can be useful for treating and/or preventing diseases or conditions caused by or associated with a virus, such as viral infections, including HIV and HCV infections.

Abstract: Disclosed are compositions and methods useful for inducing an immunogenic response in a subject or host. In particular, the compositions and methods may be directed to carbohydrate HIV vaccines and to methods of producing a carbohydrate HIV vaccine by introducing antigenic sugars into mimics of the glycans of the HIV envelope glycoproteins gp120 and gp41.

Abstract: One can treat a viral infection by first administering at least one first antiviral compound for a first time period and then, after the end of the first time period, concurrently or subsequently administering the at least one first antiviral compound and at least one second antiviral compound for a second period. In some cases, after the end of the second period, the same at least one second antiviral compound that was administered during the second time period may be administered for a third time period without concurrent or subsequent administration of the at least one first antiviral compound.

Abstract: Disclosed are methods for screening that may be used to identify an inhibitor of HCV p7 protein. The methods may include incorporating an HCV p7 protein into a membrane to create an HCV p7-containing membrane that has an increased permeability relative to a membrane that does not contain HCV p7 protein. The HCV p7 protein may be contacted with a test compound, and the permeability of this HCV p7-containing membrane then may be compared to an HCV p7-containing membrane in which the HCV p7 protein has not been contacted with the test compound. The inhibitor of HCV p7 protein may be identified by observing a decrease in the permeability of the HCV p7-containing membrane in which the HCV p7 protein has been contacted with the test compound.

Abstract: Disclosed are methods to treat HCV infection by administering an iminosugar derivative compound that is effective to inhibit the activity of HCV p7 protein, and methods by which to screen for compounds that inhibit the activity of p7 protein or variants thereof. The disclosed N-substituted imino compounds, and pharmaceutical compositions thereof, inhibit the capacity of HCV p7 to permeabilize membranes.
