The Molecular Biology of Coronaviruses

open access: yes, 1997
This chapter discusses the manipulation of clones of coronavirus and of complementary DNAs (cDNAs) of defective-interfering (DI) RNAs to study coronavirus RNA replication, transcription, recombination, processing and transport of proteins, virion assembly, identification of cell receptors for coronaviruses, and processing of the polymerase.

The Role of CD4 T Cell Repertoire and Immune Memory Mechanisms in Vaccination and Infection Immunity

open access: yesImmunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT CD4+ T cells orchestrate adaptive immunity against respiratory viruses through functionally distinct subsets, yet the qualitative differences between vaccine‐ and infection‐induced responses remain incompletely understood. This review summarizes current evidence on how CD4+ T cell subsets shape the magnitude, breadth, and durability of ...

Detection and Phylogenetic Analysis of Alphacoronaviruses in Bat Populations of Rostov and Novosibirsk Regions of Russia, 2021–2023

open access: yesMicrobiology Research
Bats are natural reservoirs for many emerging viruses, including coronaviruses that were probably progenitors to human coronaviruses with epidemic and pandemic potential, which highlights the importance of screening studies of bat-derived viruses.

Identification and Optimization of a Truncated Hs‐1‐Derived Antimicrobial Peptide for Enhanced Broad‐Spectrum Antiviral Activity

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
Can a shorter peptide be a better antiviral? Structure‐guided optimization of the amphibian peptide Hs‐1 reveals a minimal α‐helical core that, after terminal modification, displays enhanced stability and submicromolar broad‐spectrum activity against enveloped viruses while maintaining a favorable safety profile. Antimicrobial peptides (AMPs) represent
