[Specifically reactive cells in experimental allergic pertussis encephalomyelitis].

Dynamics of emergence of specific reactive cell (SRC) with respect to the brain antigen in the draining regional lymph nodes and peripheral blood was studied in experimental whooping cough allergic encephalomyelitis (EAE) in guinea pigs. The greatest number of SRC in the regional lymph nodes, that markedly decreased by the 9th day of sensitization, was revealed in the middle of the EAE incubation period (the 6-7th day), whereas the peripheral blood showed the highest SRC number during this period. The SRC number rose in the regional lymph nodes and dropped in the peripheral blood at the height of EAE progress (the 20th day). It is concluded that SRC found may be attributed to T lymphocyte population.
