What Antibody Repertoires See: Structural and Immunogenetic Insights Into Influenza A Virus Hemagglutinin Recognition

Immunological Reviews, Volume 342, Issue 1, September 2026.
ABSTRACT Human infection with or vaccination against influenza A virus has been one of the most informative systems for understanding how human antibody repertoires recognize viral glycoproteins. Decades of antibody isolation, repertoire sequencing, lineage tracing, serology, viral antigenic evolution, and structural biology have shown that antibody ...

CD4+ T‐cell responses directed towards A/H5N1‐derived haemagglutinin peptides increase in patients with seasonal influenza A virus infection

Clinical &Translational Immunology, Volume 15, Issue 8, 2026.
Abstract Objectives Recent outbreak of influenza A/H5N1 viral infections in birds and mammals worldwide prompted renewed concerns over an emerging H5N1‐related influenza pandemic in the generally immunologically‐naive global population. Cross‐reactive CD4+ T cells between A/H1N1 and A/H5N1 subtypes targeting internal and surface influenza proteins have
