Abstract
Adaptive immune response can be accompanied by immunodominance which
manifests itself by competition of different clones of antigen-specific lymphocytes and
corresponding antibodies. This competition can lead to hierarchy of antibodies and to
competitive exclusion of some of them. In this work we develop a new model of
immunodominance based on partial integrodifferential equations and take into
account random mutations of B-cell receptors, competition of cell clones for
resources, and epitope-specific virus neutralization. Dynamics of immune response is
studied, and it is shown that immunodominance can weaken the immune response
since the dominating antibodies are not necessarily most efficient for virus
neutralization, as observed in COVID-19 patients.
