疟疾免疫记忆的建立是缓慢的、不完整的和短暂的。抗疟疾免疫记忆产生和维持的机制尚不清楚。本研究评估了程序性细胞死亡-1 (PD-1)在疟疾免疫记忆建立中的可能作用。在感染柏氏疟原虫(PbANKA)后,我们通过单克隆抗体治疗比较了WT和缺乏PD-1小鼠的自然免疫、获得性免疫和免疫记忆。我们发现PD-1敲低组的寄生虫血症水平显著降低。PD-1消除后,树突状细胞、Th1和t -滤泡辅助细胞显著增加。此外,记忆T、长寿命浆细胞和血清抗体的产生也显著增加。因此,PD-1的消除诱导了更强的自然和获得性免疫反应,增强了对寄生虫的免疫记忆。
The establishment of malaria immune memory is slow, incomplete, and short-lived. The mechanisms underpinning the generation and maintenance of anti-malarial immune memory remain unclear. This study evaluated the possible role of programmed cell death-1 (PD-1) in the establishment of malaria immune memory. Following infection byPlasmodium bergheiANKA (PbANKA) we compared natural immunity, acquired immunity, and immune memory between WT and mice lacking PD-1 via monoclonal antibody treatment. We found that parasitemia levels were significantly lower in the PD-1 knockdown group. After PD-1 elimination, dendritic cells, Th1, and T-follicular helper cells increased significantly. In addition, memory T, long-lived plasma cells, and serum antibody production also increased significantly. Therefore, PD-1 elimination induced stronger natural and acquired immune responses and enhanced immune memory against the parasite.
