Human antibodies targeting a novel flu epitope for use as a universal flu vaccine and treatment

Scientists at Vanderbilt have discovered a new class of human antibodies specific to a novel target for the detection, prevention, and treatment of influenza A viruses (IAV). Using structural characterization, they have identified a novel antigenic site on the hemagglutin (HA) head domain that may be targeted by multiple antibodies simultaneously in a non-competitive manner. They found that administration of these antibodies against an otherwise lethal challenge with viruses of H1N1, H3N2, H5N1, or H7N9 subtypes confers protection when used as prophylaxis or therapy against major IAV subtypes that are pathogenic to humans. These antibodies may prove effective as a universal influenza treatment or in the design of a universal influenza vaccine.

New Clostridium Difficile Recombinant Toxin for Safe Vaccine Development

A structural biology approach has identified a conserved region common to multiple Clostridium toxins. Specific mutations of the protein sequence in this region prevent the toxins from entering into intestinal cells, thereby preventing widespread tissue damage. These recombinant Clostridium toxins may be used to create a multivalent vaccine to protect against multiple species of Clostridium. Furthermore, the recombinant toxin may be used as a safer alternative to the native toxins in vaccine manufacturing. This discovery stems from a collaboration between the laboratories of Dr. Borden Lacy of Vanderbilt University and Dr. Roman Melnyk of the Hospital for Sick Children.

Long-Lasting and Self-Sustaining Cell Therapy System

Researchers at Vanderbilt have created a novel drug delivery system using two distinct T-cell populations that interact to promote engraftment and persistence in pre-clinical models, increasing the efficacy of T-cell therapies. Furthermore, "booster" treatments can be administered months after the first dose to produce an expansion of antigen specific T cells. These advantages result in longer-term therapeutic efficacy and could reduce the number of treatments required. This system also represents a viable self-renewing platform for the delivery of biologic drugs in patients who would otherwise require frequent administration.
