Novel Anti-HIV Compounds Using Peptides or Peptide Mimetics

The subject invention describes a new class of compounds (such as peptides or mimetics) that target viral RNAs and inhibit the viral life cycle by blocking the viral recognition process. More specifically, these compounds are the first against an RNA Target - currently there are no clinical drugs against RNA targets in the treatment of any type of human disease.

Modified griffithsin tandemers for enhanced activity and reduced viral aggregation

Griffithsin (GRFT) is a lectin with potent antiviral properties that is capable of preventing and treating infections caused by a number of enveloped viruses (including HIV, SARS, HCV, HSV, and Japanese encephalitis) and is currently in clinical development as an anti-HIV microbicide. In addition to its broad antiviral activity, GRFT is stable at high temperature and at a broad pH range, displays low toxicity and immunogenicity, and is amenable to large-scale manufacturing.

Human Antibodies Against Middle East Respiratory Syndrome Coronavirus

No effective therapeutics or vaccines against Middle East Respiratory Syndrome Coronavirus (MERS-CoV) are available. The human-to-human aspect of transmission and the high mortality rate associated with MERS-CoV infection have raised concerns over the potential for a future MERS-CoV pandemic and emphasized the need for development of effective therapeutics and vaccines.

Methods of Treating Giardiasis Using FDA-Approved Compounds

This technology includes a group of at least twenty-nine, diverse, commercially available compounds that are newly identified for activity against Giardia lamblia parasites. At least six of the candidate compounds, Bortezomib, Decitabine, Hydroxocobalamin, Amlexanox, Idarubicin, and Auranofin have preexisting FDA approval for human use for other (non-Giardia) conditions. Another three compounds, Fumagillin, Nitarsone and Carbadox have preexisting approval for veterinary use for non-Giardia conditions.

Monoclonal Antibodies That Bind to the Underside of Influenza Viral Neuraminidase

Current influenza vaccines mainly induce antibodies against the surface glycoprotein hemagglutinin (HA) that block viral attachment to its host receptors and viral membrane fusion to the host cell. The immunodominant head region of HA undergoes antigenic drift and antibodies directed to the head confer little cross-protections between strains or subtypes.

Self-Assembled Ferritin Nanoparticles Expressing Hemagglutinin as an Influenza Vaccine

NIH inventors at the Vaccine Research Center have developed a novel influenza virus hemagglutinin (HA)-ferritin nanoparticle influenza vaccine that is easily manufactured, potent, and elicits broadly neutralizing influenza antibodies against multiple strains of influenza. This novel influenza nanoparticle vaccine elicited two types of broadly neutralizing, cross-protective antibodies, one directed to the highly conserved HA stem and a second proximal to the conserved receptor binding site (RBS) of the viral HA, providing a new platform for universal and seasonal influenza.

Neutralizing Antibodies to Influenza HA and Their Use and Identification

The effectiveness of current influenza vaccines varies by strain and season, in part because influenza viruses continuously evolve to evade human immune responses. While the majority of seasonal influenza infections cause relatively mild symptoms, each year influenza virus infections result in over 500,000 hospitalizations in the United States and Europe. Current standard of care for individuals hospitalized with uncomplicated influenza infection is administration of neuraminidase inhibitors.

Stabilized Group 2 Influenza Hemagglutinin Stem Region Trimers and Uses Thereof

Researchers at the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases (NIAID) have designed influenza vaccine candidates based on group 2 influenza hemagglutinin (HA) proteins. These group 2 HA proteins were engineered to remove the highly variable head region and stabilize the remaining stem region. The researchers then fused the engineered group 2 HA stabilized stem with a ferritin subunit. The resulting fusion protein can self-assemble into nanoparticles which display group 2 HA stem domain trimers on their surface.

Chimeric SHIV Gag Proteins Optimize T-Cell Response Against HIV Gag

HIV Gag has been included in nearly all HIV vaccines entering clinical trials because of its importance in SIV models and its correlation with protection in HIV-infected long-term non-progressors. However, HIV Gag has proven less immunogenic than Env in phase I clinical trial studies. Through sequence comparison, two regions in HIV Gag have been identified as contributing to the decreased immunogenicity observed for HIV Gag. Replacement of these regions with corresponding SIV sequences significantly increased the resulting T-cell response to HIV Gag in mice.

Increased Protein Expression Vector for Vaccine Applications

An expression vector with a unique promoter that results in higher level of protein expression than vectors currently in use is available for licensing from the NIH. The elevated levels of expression are achieved through use of a specific promoter, known as CMV/R, in which the Human T-Lymphotrophic Virus (HTLV-1) Long Terminal Repeat (LTR) R-U5 region is substituted for a portion of the intron downstream of the CMV immediate early region 1 enhancer (Barouch et al., 2005). Sequences of 95% or better homology to CMV/R can be used as well.
