SARS-CoV-2 NSP15 Screening: Thymopentin and Oleuropein
2026-08-13
The 2021 study used structure-based virtual screening of a natural-product library against SARS-CoV-2 NSP15 and then applied molecular-dynamics simulations to prioritize thymopentin and oleuropein. Its main contribution is a hypothesis-generating route to target a viral immune-evasion enzyme, while the computational design means biochemical and cellular validation remain necessary.

HIV-1 Remodels Nuclear Pores to License Infection
2026-08-09
This study shows that HIV-1 cell–cell spread overcomes the resistance of resting CD4+ T cells by activating a CD4–LCK–CDK1 pathway that remodels nuclear pore complexes and promotes capsid nuclear import. The work separates contact-dependent signalling from viral dose, providing a mechanistic explanation for efficient infection of resting T cells in vivo and for the dominance of virological-synapse transmission.
