Piplartine, also called piperlongumine, had protective effects against hearing loss induced by aminoglycoside antibiotics in zebrafish and mouse models of kanamycin-induced hair cell loss. Kanamycin is a member of the aminoglycosides, a group of antibiotics that have broad-spectrum activity against gram-negative bacteria, including multidrug resistant strains.

A strategy inspired by deficient HIV replication could be used as a treatment to reduce viral load in patients living with HIV and help control the pandemic of the retrovirus. Scientists from the University of California San Francisco want to use HIV against itself by using a parasitic version of the pathogen.

Researchers at Leiden University have synthesized semisynthetic guanidino lipoglycopeptides with in vitro and in vivo activity gram-positive bacteria, including methicillin-resistant and vancomycin-resistant Staphylococcus aureus.

Infection or cure? Scientists from Tel Aviv University and the University of Glasgow genetically modified the Toxoplasma gondii to bring a protein inside neurons. The novelty of using a protozoan that can travel from the gut to parasitize the CNS contrasts with the possibility of causing a disease. The scientists are already working on how to avoid it.

Arcturus Therapeutics Holdings Inc. has announced its pandemic influenza vaccine is on track to enter a phase I clinical trial in Q4 of 2024. The vaccine, ARCT-2304, utilizes Arcturus’ STARR self-amplifying mRNA and LUNAR delivery platform technologies to deliver antigens designed to elicit a protective response against the H5N1 strain of avian influenza.

Armed with $55 million in series A funds and a U.S. government contract, Cambridge, Mass.-based Red Queen Therapeutics Inc. launched operations this week, with plans to advance its novel stapled lipopeptide platform, which creates new antiviral therapies that do not rely on the immune system to work.
