[Immunochemical characteristics of the population structure of antibody-producing cells in experimental influenza].

The authors presented the results of population study of specific IgG-antibody-forming cells (AFC) in the pool of mice splenocytes performed in the time-course of simulated influenza with the help of experimental mathematical approach which permitted making a detailed observation of the functional structure of the population and analysing the changes in the spectrum of the AFC subpopulations in the time-course of viral disease. Mathematical simulation of the main stage of immunopointed identification of AFC on +nitrocellulose filters (NCF) permitted the verification of the ratio between the characteristic features of the spots on the NCF and the number and affinity of cell-secreting IgG antibodies. New data are obtained on the formation of the population of +virus-specific IgG-AFC which are featured by discreteness of the AFC +affinity ++ spectrum, cyclic changes in their activity and shifts in the stages of the AFC subpopulation activity. The authors substantiated the necessity to revise the existing theoretical models of the formation of humoral immune response to viral infections.
