GSK3 Inhibition as Host-Directed TB Therapy
2026-08-12
The 2024 iScience study identifies glycogen synthase kinase 3 as a host pathway that supports intracellular Mycobacterium tuberculosis growth. By combining pharmacological screening, CRISPR knockout, RNA interference, apoptosis analysis, and phospho-proteomics, the authors establish GSK3 inhibition as a mechanistically supported host-directed strategy rather than a conventional antibacterial approach.

Concanavalin A and Conserved Coronavirus N-Glycans
2026-08-10
A 2026 Journal of Virology study identifies conserved high-mannose N-glycans near the coronavirus spike S2′ cleavage site as a broad-spectrum antiviral vulnerability. By combining fusion, pseudovirus, authentic-virus, biochemical, and mouse models, the authors show that concanavalin A blocks spike activation and entry rather than targeting rapidly changing antibody epitopes.
