NIH researchers report that in severe influenza, survival improves at late stages only when antivirals are combined with therapies that repair lung damage or limit harmful T-cell responses, explaining why anti-inflammatory treatments alone are often ineffective.

Aligos Therapeutics Inc. and Katholieke Universiteit Leuven (KU Leuken) have synthesized antiviral compounds reported to be useful for the treatment of coronavirus acute respiratory syndrome, norovirus and picornavirus infections.
Adaptor protein-2 associated kinase 1 (AAK1) is key in clathrin-mediated endocytosis, which diverse viruses hijack in order to infect cells. Inhibiting AAK1 has been shown to block the entry of hepatitis C, dengue and rabies viruses into cells.
Human rhinovirus (HRV) is the most frequent cause of upper respiratory infections and a key trigger of asthma exacerbations. No effective anti-HRV therapies exist, and vaccine efforts have been unsuccessful due to its extreme genetic and antigenic diversity, with over 160 known serotypes.
Researchers from the CUNY Advanced Science Research Center and their collaborators recently published a paper in Science Advances on Aug. 27, 2025, about synthetic carbohydrate receptors (SCRs) and their potential as broad-spectrum antivirals by targeting the viral envelope N-glycans. They described the antiviral activity of a series of tetrapodal SCRs both in vitro and in vivo, showing their potential as broad-spectrum inhibitors of viral infection.
The COVID-19 pandemic sent the world into a tailspin, raising ongoing concerns about biosecurity, a subject that encompassed the better part of the morning June 16, the first day of the Biotechnology Innovation Organization’s annual conference in Boston.
Octant Inc. has received a $4.9 million grant from the Gates Foundation to support a new therapeutics program focused on human papillomavirus (HPV)-related cancers. The initiative will develop affordable, broad-spectrum, small-molecule antiviral drugs designed to disrupt the interaction between hundreds of variants of the HPV E6 protein and the tumor suppressor protein p53.
Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system caused by lytic infection of oligodendrocytes by pathogenic strains of the JC polyomavirus (JCV). This opportunistic virus has long persisted as a serious threat during periods of immunosuppression, and currently, there is no effective antiviral treatment available.
