Atea Pharmaceuticals Inc. recently presented preclinical data on two of its compounds, AT-2490 and AT-587, which have shown promising antiviral potential for treating hepatitis E virus infection.

Aiming to develop a vaccine candidate against human adenovirus-55 (HAdV-55) infections, researchers from the First Affiliated Hospital of Guangzhou Medical University (China) and collaborators have generated a replication-incompetent rAd55-5E4.

HIV-1 persistence in latent reservoirs of T lymphoid and myeloid origin is a major barrier for the cure of the disease, with complex and multifactorial mechanisms behind HIV-1 latency; thus, investigating these mechanisms is key for future targeted HIV therapies.

Gilead Sciences Inc.’s integrase strand transfer inhibitor (INSTI) GS-3242 is in early clinical development for HIV infection (NCT07001319). The company presented nonclinical data on the candidate at the recent CROI meeting in Denver.

CARB-X is awarding $1.2 million to the Andrew G. Myers research group at Harvard University to develop enhanced antibiotics that target multidrug-resistant gram-negative bacterial pathogens, including Escherichia coli and Klebsiella pneumoniae, to treat urinary tract infections, pneumonia and bloodstream infections.

A new isoform of proliferating cell nuclear antigen (PCNA) – cancer-associated PCNA (caPCNA) – that is specifically expressed in cancer tissues has been reported. Because cancer cells and HIV-infected cells have similar features, researchers from City of Hope National Medical Center tested the anit-HIV effects of a small-molecule compound, AOH-1996, that targets caPCNA.

Broadly neutralizing antibodies (bNAbs) target conserved HIV envelope regions to neutralize diverse strains, eliminate infected cells and reduce viral reservoirs, complementing antiretroviral therapy and supporting prevention and functional cure strategies.
