免疫学免疫学免疫学
遗传学遗传学是一个
传染性疾病传染性疾病

背景情况:

宿主基因和蛋白质表达影响疟疾易感性.
导致疟疾保护的免疫细胞平衡,细胞因子概况和基因表达模式尚未完全理解.
在获得免疫的发展过程中,宿主敏感性的决定因素在很大程度上是未知的.

研究的目的:

为了研究免疫细胞种群,细胞因子分泌和基因表达在儿童与不同的临床疟疾敏感性.
为了确定基线免疫特征,预测易感性症状疟疾.

主要方法:

周围血液单核细胞 (PBMC) 是从马里4-6岁的儿童身上在疟疾季节的开始,高峰和结束时收集的.
免疫细胞组成和细胞因子分泌的特征是每时间点的20名儿童 (10名受保护,10名敏感).
基因表达模式分析了每个时间点的六名儿童 (每个队列三名).

主要成果:

易受感染的儿童在传染季节之前表现出高调的炎症基因 (例如CXCL10,STAT1) 和亡基因 (例如XAF1).
在疟疾高峰季节,受保护儿童的HLA-DR+ CD4 T细胞频率更高.
通过疟疾病原体刺激后的细胞因子分泌在所有时间点和群体中都是可比的.

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
