Use of recombinant-derived homologous antigens, which has preceded the isolation of the virus in cell culture, should improve the sensitivity and specificity of results obtained with available heterologous antigens.
IL-17 production by flagellin a- or flagellin b-immunized T cells when stimulated with the homologous antigen was significantly higher than that of T cells stimulated with heterologous antigen (P < 0.05; Figures 7(c) and 7(d) and Figures 7(e) and 7(f)).
