Infected B2 macrophages stimulated homologous T cells from unvaccinated chicks. Production of NO by macrophages co-cultured with T lymphocytes (A). Activation of T lymphocytes was determined by detection of IFNγ (B). The differences between the B2 and B19 macrophage stimulation not exposed to the NP cDNA vaccine were p < 0.001 for both figures A and B.
