The response of individual volunteers to <i>L. major</i> lysate.

<p>Freezed/thawed antigens of <i>L. major</i> were used to stimulate the PBMCs in culture as previous disease indicator. The responses of <i>L. major</i> recovered individuals were potentially detected at CD4 level. Each point represents response of each individual. Horizontal bars represent the median value of CD4⁺/IFN γ⁺ T cells in the related group. Statistical analysis shows a significant difference between R.A2⁺ (HLA-A2⁺ recovered individuals) and R.A2⁻ (HLA-A2⁻ recovered individuals) groups with H.A2⁺ individuals (HLA-A2⁺ healthy donors) with <i>p</i> value<0.05.
