Human and Veterinary Cancer Therapeutic Agent Utilizing Anthrax Toxin-Based Technology

Due to the disorganized nature of blood vessels that run through tumors, chemotherapeutic agents often fail to penetrate tumors and kill cancer cells at the tumor’s center. This can lead to ineffective chemotherapeutic treatments, because tumors can quickly grow back if the entire tumor is not destroyed. NIH researchers have developed a therapeutic...

Exposure and Activity Detection Assays for Anthrax Lethal Factor and Lethal Toxin

This CDC developed invention identifies an assay for extremely fast and sensitive detection of Bacillus anthracis lethal toxin (LTx), the toxin responsible for the lethal effects of anthrax infection. This assay has already been successfully tested in animals and will allow for early detection of anthrax exposure and screening of lethal factors to...

Novel Epitopes of Bacillus anthracis Lethal Factor for Development of Diagnostics and Therapeutics

CDC researchers have characterized epitopes of Bacillus anthracis Lethal Factor (LF), a critical component of the B. anthracis lethal toxin. These epitopes may allow for development of therapeutics for the treatment or prevention of B. anthracis infection. They may also allow screening for B. anthracis LF in a sample and development of a peptide anthrax...

Linear Epitopes of Anthrax Toxin Protective Antigen for Development of a Peptide Vaccine

Bacillus anthracis is a gram-positive, spore-forming bacteria that causes anthrax infection in humans. CDC inventors have identified epitope sequences of B. anthracis protective antigen (PA) that may be useful for development of peptide-based anthrax vaccines. This invention also relates to methods for determining whether post-vaccination protection...

Engineered Anthrax Toxin Variants that Target Cancer

This technology describes the use of novel mutated anthrax protective antigen (PA) protein variants to target tumor cells and tumor vasculature. NIH scientists have engineered two PA variants that selectively complement one another and combine to form active octamers that target tumor cells. This controlled oligomeric activation of the PA proteins...
