Key result
Alanine scanning mutagenesis revealed that a high density of residues along the entire HRV interpentamer interface are critical for viral infectivity, assembly, and conformational stability.
Why the study?
Development and design of effective anti-HRV drugs relies on fundamental knowledge about targeted viral elements and their roles during specific steps of the infectious cycle.

Detailed structural insights into HRV may guide antiviral design; leaves open clinical translation pending further studies.
High-density mutational analysis of the HRV capsid interpentamer interface demonstrates that most interfacial residues are critical for viral infectivity, highlighting this region as a promising target for antiviral drug design.
Valiente et al. (2022) studied Human Rhinovirus (HRV) infection. Alanine scanning mutagenesis of capsid interpentamer interfaces vs. Wild-type HRV-B14 was evaluated on Viral infectivity (progeny infectious titers). Alanine scanning mutagenesis revealed that a high density of residues along the entire HRV interpentamer interface are critical for viral infectivity, assembly, and conformational stability.
