At the World Vaccine Congress this week, Longhorn Vaccines & Diagnostics LLC presented the preclinical characterization of LHNVD-501, a half-life-extended, humanized IgG monoclonal antibody (mAb) targeting peptidoglycan (PGN). PGN is a conserved structural component shared across bacterial species and an upstream driver of sepsis, as well as metabolic disease, autoimmune disorders and neurodegeneration.
