CNS Therapeutics That Target Neuronal Ceroid-Lipofuscinoses and Thioesterase Deficiency Disorders

Clinically known as Neuronal Ceroid-Lipofuscinoses (NCL), Batten disease, is a rare neuron killing disease and one of the lysosomal storage disorders (LSDs).  It is associated with a mutation or lack of palmitoyl-protein thioesterase-1 (PPT1) gene. It manifests very early in a child's life causing absence of brain activity as early as 4 years of age.

IL7Rα-Specific Antibody for Treating Acute Lymphoblastic Leukemia (ALL)

Acute lymphoblastic leukemia (ALL) is the most common cancer in children with approximately 3,250 new cases occurring per year in the United States. About 20% of cases are refractory to current treatment protocols and there is a desperate need for targeted therapies that do not result in adverse side effects such as cognitive impairment. 

Antibodies to TMC1 Protein for Hearing Loss

This technology includes antibodies for TMC1 protein as a treatment for hearing loss. TMC1 is one of the common genes causing hereditary hearing loss. Our laboratory used synthetic peptides corresponding to the TMC1 protein to immunize rabbits. The resulting antisera were shown to bind to TMC1 protein expressed in heterologous expression systems. TMC1 protein is required for the transduction of sound into electrical impulses in inner ear sensory cells.

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.

Stabilized Influenza Hemagglutinin Stem Region Trimers and Uses Thereof

An effective universal influenza vaccine would eliminate the uncertain and costly process of seasonal influenza vaccine development each year. Researchers at the National Institute of Allergy and Infectious Diseases (NIAID) are developing immunogens which elicit neutralizing antibodies to the highly conserved stem region of the influenza viral protein hemagglutinin.

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.

Novel Multivalent Nanoparticle Vaccines

Current seasonal influenza vaccines are designed to elicit immunity to circulating strains of influenza each year. The targeted strains are selected based on predictions of which strains are likely to be predominant in the human population for a given year. This prediction must be made well ahead of the influenza season to allow time for vaccine production and can be inaccurate.
