The influenza hemagglutinin is a critical regulator of disease expression during influenza virus infection and serves as a major target for the host immune response to this pathogen. In this report, we have analyzed an immunodominant site on the hemagglutinin (residues 202-221) recognized by murine class I MHC-restricted T lymphocytes. This analysis has revealed evidence for the duplication of a T cell recognition site within the region 202-221. We have also identified critical amino acids necessary for class I-restricted T cell recognition within these two epitopes. In addition, we provide evidence that a site on the influenza hemagglutinin recognized by neutralizing antibody directly overlaps with an epitope recognized by class I MHC-restricted CTL.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
