To investigate the role of innate immunity in variable efficacy of Mycobacterium bovis BCG vaccination in Malawi and the United Kingdom, we examined 24-h tumor necrosis factor alpha, interleukin-1beta (IL-1beta), and IL-10 responses to mycobacterial purified protein derivatives (PPDs). The rank order in stimulatory potency for different PPDs was the same for all three cytokines. Before vaccination Malawians made higher pro- and anti-inflammatory responses than did United Kingdom subjects. Fewer than 5% of United Kingdom subjects made IL-10 in response to any PPD, compared to 19 to 57% responders among Malawians. Priming for regulatory IL-10 may contribute to the smaller increase in gamma interferon responses in Malawians compared to United Kingdom subjects following BCG vaccination.
为研究天然免疫在马拉维和英国卡介苗接种效果差异中的作用,我们检测了对分枝杆菌纯化蛋白衍生物(PPD)的24小时肿瘤坏死因子α、白细胞介素-1β(IL-1β)和IL-10反应。三种细胞因子对不同PPD的刺激效力排序相同。接种疫苗前,马拉维人产生的促炎和抗炎反应高于英国受试者。英国受试者中对任何PPD产生IL-10反应的不到5%,而马拉维人的反应者比例为19%至57%。与英国受试者相比,马拉维人接种卡介苗后γ干扰素反应增幅较小,可能与调节性IL-10的启动有关。
